As shown in fig. 4, the step of recognizing the change of the graduation mark in the graduation mark image by the central control unit 30 of the visual perception system of the present invention specifically includes the following steps:

and S10, acquiring a scale mark image on the zero position adjusting knob.

As shown in fig. 5, the scale image obtained at this time has 5 scales in the field of view. It can be understood that the number of the scale lines in the visual field can be changed by adjusting the distance between the camera and the adjusting knob.

S20, recognizing the feature and the pixel position of each scale in the scale image, and sequentially setting different labels for recognition for each scale.

Before identifying the scale marks in the scale mark image, the central control unit 30 of the visual perception system of the present invention needs to learn, i.e., enter a learning mode to learn the features of the short scale marks and the long scale marks respectively.

In the invention, the characteristic identification of each scale mark in the scale mark image comprises the identification of the shape characteristic and the color characteristic of the scale mark.

The shape feature recognition includes height, width, edge feature recognition, and the like. As shown in fig. 7, after learning and recognition in the learning mode, the respective features of the long and short scale lines are stored, and the system calls and compares the features in the subsequent recognition process.

Because the system obtains the characteristics of the long and short scale marks in the learning mode, the system identifies the characteristics of each scale mark in the scale mark image in a normal identification state, identifies the long and short scale marks, and determines the position of each scale mark in the image by combining the identified pixel positions.

In order to facilitate the comparative analysis with subsequent images, different labels are arranged on each scale mark in sequence in the identified scale mark image. As shown in fig. 8, each graduation mark is labeled with "lineX".

Preferably, the labels of the present invention are always arranged to be sequentially increased from the rightmost side of the scale image to the left, and are sequentially line1, line2, line3, … … and lineN. As shown in fig. 8, the rightmost label of the image is line1, line2, line3, … …, lineN are gradually increased to the left. The invention arranges the label from a fixed direction, which is convenient for comparison and identification after the position of the scale mark changes in the identification process.

And S30, dynamically acquiring the scale mark images in the rotation process of the adjusting knob and carrying out characteristic and pixel position tracking identification on each scale mark in the images.

In the process of rotating the adjusting knob, the invention needs to dynamically acquire the scale mark image of the adjusting knob and track and identify the characteristic and pixel position of each scale mark in the image so as to compare the characteristic and pixel position with the previous identification result in real time and obtain the dynamic position change of each scale mark.

It will be appreciated that the identified tick marks may be re-labeled in subsequent dynamically acquired tick mark images to facilitate subsequent comparative analysis.

The machine vision algorithm run by the intelligent process control module 32 of the present invention includes:

and the machine learning algorithm is used for extracting the characteristics of the object in the machine learning mode and saving the characteristics for the subsequent machine vision identification process.

And the machine recognition algorithm is used for recognizing the object or the figure, analyzing the characteristics and the pixel positions of the object or the figure in the image shot by the camera and automatically labeling the recognized object or the figure.

When the machine recognition algorithm recognizes that the object or the graph moves in the visual field of the camera, the size and the pixel position of the object or the graph in the image shot by the camera can be continuously tracked, recognized and analyzed, and the label can move along with the object or the graph shot by the camera. And the data such as the size, the pixel position, the label name and the like of the object or the figure which changes continuously in the image shot by the camera can be seen in the running data of the visual perception system, and the data can be used as the subsequent execution judgment data.

And S40, comparing the current recognition result with the previous recognition result, and judging that the adjustment of the adjusting knob changes one scale mark when the existing scale mark on the rightmost side of the current scale mark image disappears or a new scale mark appears. It will be appreciated that the rightmost tick mark change of the tick mark image is used in this embodiment, as is the principle if the leftmost tick mark change of the tick mark image is used instead.

As shown in a and b in fig. 8, after the labels in a and b are compared, the pixel position change of a scale mark can be obtained, and in b, a new scale mark appears at the rightmost side, so that the rotation direction can be judged to be clockwise, and the adjusting knob adjusts a scale point.

As shown in fig. 11, the calculating the current adjustment value of the adjustment knob according to the embodiment of the present invention specifically includes the following steps:

s51, it is determined whether the rightmost edge in the ruled-line image is to increase or decrease one ruled line.

S52, if the current adjustment value is decreased, the adjustment knob is judged to rotate a scale anticlockwise, the original label in the scale line image is changed into line (d-1), d is the label value before the change of the scale, and the current adjustment value of the adjustment knob adopts the formula: V-Vp-Vu calculation, and the V value is recorded. The V value is sent to the display unit 40 for display and called for the next calculation.

S53, if increasing, judging that the adjusting knob rotates a scale clockwise, and changing the original label in the scale line image from line to line (y-1), wherein y is the label value before changing a scale, and the current adjusting value of the adjusting knob adopts the formula: v ═ Vp + Vu was calculated and the V value was recorded. The V value is sent to the display unit 40 for display and called for the next calculation.

Wherein, V is the current regulating value of adjusting knob, Vp is the regulating variable before the adjusting knob changes a scale point, and Vu is the value of adjusting knob changes a scale point.

Therefore, when the current adjustment value is calculated, only the adjustment quantity before the change needs to be obtained, and then the value of one scale is directly added (or subtracted) when a new scale mark is identified.

As shown in c in fig. 8, the labels are always kept to increase from the rightmost side to the left, i.e. line1 is always at the rightmost side of the image.

After the setting step two and the setting step three are completed, the central control portion 30 obtains each adjustment value U of the scale mark 111 of the adjustment knob 11 of the sighting telescope 10, where U is | Vu |, and Vu is a value of the adjustment knob that changes by one scale point; the central control section 30 obtains a zero point of the adjustment knob 11 of the scope 10, which is a reference point of the values of the other points of the scale 111. Referring to a in fig. 8, when the adjustment knob 11 of the scope 10 is at the zero point, the image of the graduation lines 111 captured by the camera 20 is as shown in the figure, the central control portion 30 identifies the graduation lines 111 in all fields of view of the camera 20 according to the color and shape feature data of the graduation lines 111 identified by the learning mode saving, and analyzes the size, shape and pixel position of each graduation line 111 in the image captured by the camera 20, the central control portion 30 sets that all the graduation lines 111 in the image captured by the camera 20 must be labeled as "line 1", "line 2", "line 3" and "line 4" … in the order from right to left according to the comparison result of the pixel position data, the current adjustment value V of the adjustment knob 11 is Vp + u, and since the adjustment knob 11 is at the zero point, Vp is equal to zero point, the adjustment knob 11 is not rotated, Vu is equal to zero point, so V is 0. When the adjustment knob 11 of the scope 10 is rotated clockwise, the scale mark 111 of the adjustment knob 11 of the scope 10 is moved from right to left in the field of view of the camera 20 until a scale mark 111j appears in the field of view of the rightmost side of the camera 20, that is, the scale mark 111 of the adjustment knob 11 of the scope 10 is rotated clockwise by a scale, referring to b in fig. 8, the central control portion 30 immediately recognizes that it is a scale mark from its color and shape characteristics and analyzes its pixel position in the image photographed by the camera 20, then determines that its position is rightmost in the image photographed by the camera 20 from the comparison of the data of the pixel position where the scale mark is located and the data of the pixel positions where other scale marks are located, and then determines that the scale mark 111 of the adjustment knob 11 of the scope 10 is rotated clockwise by a scale from the scale mark newly appearing in the rightmost field of view of the camera 20, since the newly appearing scale line is located at the rightmost side of the image captured by the camera 20, and the central control section 30 labels it as "line 1" according to the rule, and changes the label of all scales originally labeled from "line" to "line (y + 1)", y being the original label value of each scale before the change by one scale, please refer to c in fig. 8, the central control section 30 sets the increment of the adjustment value of the adjustment knob 11 to be positive when the adjustment knob 11 of the scope 10 is rotated clockwise, then the current adjustment value V of the adjustment knob 11 is Vp + Vu, Vp is 0, Vu is U, so V is U; meanwhile, referring to a in fig. 8, when the adjustment knob 11 of the scope 10 is rotated clockwise from the zero point, the leftmost line labeled "line 5" disappears in the leftmost field of view of the camera 20, referring to b in fig. 8, since the line is not in the field of view of the camera 20, i.e., it is not in the identification area of the central control portion 30, the central control portion 30 loses its identification, the central control portion 30 immediately cancels its identification label, and the label name and the data such as the size and the pixel position in the image captured by the camera 20 disappear from the system, referring to c in fig. 8; as long as the adjusting knob 11 of the scope 10 is rotated clockwise, the situation that the leftmost scale mark disappears in the leftmost field of view of the camera 20 will occur, and since the scale mark is not in the field of view of the camera 20, i.e. it is not in the identification area of the central control portion 30, the central control portion 30 loses its identification, the central control portion 30 immediately cancels its identification tag, and the tag name and the data such as the size and the pixel position in the image captured by the camera 20 will disappear from the system, so that the scale mark which disappears in the leftmost field of view of the camera 20 will not be explained any more in the case that the adjusting knob 11 of the scope 10 is rotated clockwise later. The dial knob 11 of the scope 10 continues to rotate clockwise until the 2 nd graduation mark appears in the rightmost field of view of the camera 20, that is, the graduation mark 111 of the dial knob 11 of the scope 10 rotates clockwise by one graduation mark, the central control portion 30 immediately recognizes that it is a graduation mark from its color and shape characteristics and analyzes its pixel position in the image photographed by the camera 20, then determines that its position is rightmost in the image photographed by the camera 20 from the comparison of the data of the pixel position where the graduation mark is located and the data of the pixel position where other graduation marks are located, then determines that the graduation mark 111 of the dial knob 11 of the scope 10 rotates clockwise by one graduation mark from the graduation mark newly appearing in the rightmost field of view of the camera 20, since the newly appearing graduation mark is located rightmost in the image photographed by the camera 20, the central control portion 30 labels it as "line 1" according to the rules, changing the labels of all scales originally labeled from "linez" to "line (z + 1)", wherein z is the original label value of each scale before changing by one scale, so that the current adjustment value V of the adjusting knob 11 is Vp + Vu, Vp is U, Vu is U, and therefore V is 2U; the dial knob 11 of the scope 10 continues to rotate clockwise until the nth scale mark appears in the rightmost field of view of the camera 20, that is, the scale mark 111 of the dial knob 11 of the scope 10 rotates clockwise by one scale from the scale n-1, the central control portion 30 immediately recognizes that it is a scale mark from its color and shape characteristics and analyzes its pixel position in the image photographed by the camera 20, then determines that its position is rightmost in the image photographed by the camera 20 from the comparison of the data of the pixel position where the scale mark is located and the data of the pixel positions where other scale marks are located, then determines that the scale mark 111 of the dial knob 11 of the scope 10 rotates clockwise by one scale from the scale mark newly appearing in the rightmost field of view of the camera 20, since the newly appearing scale mark is located rightmost in the image photographed by the camera 20, according to the rule, the central control unit 30 labels the label as "line 1", changes the labels of all scales originally labeled from "line" to "line (w + 1)", where w is the original label value of each scale before the change of one scale, and then the current adjustment value V of the adjustment knob 11 is Vp + Vu, Vp (n-1) U, and Vu is U, so V is nU; since the zero point of the adjustment knob 11 of the scope 10 and each adjustment value U of the graduation mark 111 have been obtained by setting, the central control portion 3 thereby calculates the current adjustment value V when the adjustment knob 11 is rotated clockwise.

Referring to a in fig. 9, when the adjustment knob 11 of the scope 10 is at the zero point, the image of the graduation lines 111 captured by the camera 20 is as shown in the figure, the central control portion 30 identifies the graduation lines 111 in all the fields of view of the camera 20 according to the color and shape characteristic data of the identified graduation lines 111 stored in the learning mode, and analyzes the size and pixel position of each graduation line 111 in the image captured by the camera 20, when the adjustment knob 11 of the scope 10 rotates counterclockwise from the zero point, in the field of view of the camera 20, the graduation line 111 of the adjustment knob 11 of the scope 10 moves from left to right, and the rightmost graduation line of the image captured by the camera 20 finally disappears from the field of view of the camera 20, that is, the graduation line 111 of the adjustment knob 11 of the scope 10 rotates by one graduation, because the anticlockwise graduation line is not in the field of view of the camera 20, that is, it is not in the recognition area of the central control section 30, the central control section 30 loses its recognition, the central control section 30 immediately cancels its recognition tag, the tag name of the scale mark, which is the recognition target of the "line 1", and the data such as the size and the pixel position thereof in the image photographed by the camera 20 disappear from the system, the central control section 30 immediately judges from the data that disappears that the scale mark 111 of the adjustment knob 11 of the scope 10 has been rotated one scale counterclockwise, please refer to b in fig. 9, at this time, the scale mark labeled as "line 1" disappears from the image photographed by the camera 20, the remaining scale marks 111 in the image photographed by the camera 20 are labeled as "line 2", "line 3", "line 4" … in the order from right to left, which does not conform to the rule set by the central control section 30, and therefore the central control section 30 changes all the scale marks of the original image photographed by the camera 20 from "line" to "line" marked "line" (d-1) ", d is the original label value of each scale before changing by one scale, and referring to c in fig. 9, the central control unit 30 sets the increment of the adjustment value of the adjustment knob 11 to negative when the adjustment knob 11 of the scope 10 is rotated counterclockwise, and then the current adjustment value V of the adjustment knob 11 becomes Vp + Vu, Vp becomes 0, and Vu becomes-U, so V becomes-U.

Meanwhile, referring to a in fig. 10, when the adjustment knob 11 of the scope 10 is rotated counterclockwise from the return zero point, the scale mark 111 of the adjustment knob 11 of the scope 10 moves from left to right until a new scale mark 111k appears in the leftmost field of view of the camera 20, referring to b in fig. 10, the central control part 30 immediately recognizes that it is a scale mark from its color and shape characteristics, and then determines that its position is leftmost in the image photographed by the camera 20 from the comparison of the data of the pixel position where the scale mark is located and the data of the pixel position where other scale marks are located, and according to the rule, the central control part 30 labels it as "line (g + 1)", "line" as the label value of the leftmost scale mark in the image photographed by the original camera 20, referring to c in fig. 10, as long as the adjustment knob 11 of the scope 10 is rotated counterclockwise, a situation occurs in which a new scale mark appears in the leftmost field of view of the camera 20, the central control portion 30 immediately recognizes that it is a scale mark from its color and shape characteristics, and then determines that its position is leftmost in the image captured by the camera 20 from a comparison of the data of the pixel position where the scale mark is located and the data of the pixel position where the other scale mark is located, and according to the rule, the central control portion 30 labels it as "line (g + 1)", "line" as the label value of the leftmost scale mark in the image captured by the original camera 20, and thus does not set forth any more about the appearance of a new scale mark in the leftmost field of view of the camera 20 in the case where the adjustment knob 11 of the rear scope 10 is rotated counterclockwise. The dial knob 11 of the scope 10 continues to rotate counterclockwise until the 2 nd line marked as "line 1" disappears in the rightmost field of view of the camera 20, that is, the scale mark 111 of the dial knob 11 of the scope 10 rotates counterclockwise by one scale, since this scale mark is not in the field of view of the camera 20, that is, it is not in the identification area of the central control section 30, the central control section 30 loses its identification, and the central control section 30 immediately cancels its label, the identification target marked as "line 1", that is, the label name of the scale mark and the data such as the size and the pixel position thereof in the image captured by the camera 20 disappear from the system, the central control section 30 immediately judges from these disappeared data that the scale mark 111 of the dial knob 11 of the scope 10 has rotated by one scale, and at this time, the scale mark marked as "line 1" disappears from the image captured by the camera 20 counterclockwise, the labels of the scale marks 111 in the image captured by the remaining camera 20 from right to left are "line 2", "line 3", and "line 4" …, which do not meet the rule set by the central control unit 30, so that the central control unit 30 changes the labels of all scales originally labeled in the image captured by the camera 20 from "line" to "line (e-1)", and e is the original label value of each scale before changing one scale, and then the current adjustment value V of the adjustment knob 11 is Vp + Vu, Vp-U, and Vu-U, so V-2U; the dial knob 11 of the scope 10 continues to rotate counterclockwise until the nth line1 marked scale line disappears in the rightmost field of view of the camera 20, i.e., the scale line 111 of the dial knob 11 of the scope 10 rotates counterclockwise by one scale from the scale n-1, since this scale line is not in the field of view of the camera 20, i.e., it is not in the recognition area of the central control portion 30, the central control portion 30 loses its recognition of this scale line, the central control portion 30 immediately cancels its recognition tag, the recognition target marked as "line 1", i.e., the tag name of the scale line and its size and pixel position in the image photographed by the camera 20, disappear from the system, the central control portion 30 immediately judges from these disappeared data that the scale line 111 of the dial knob 11 of the scope 10 has rotated by one scale from these disappeared data, and then the "line 1" marked counterclockwise disappears from the image photographed by the camera 20, the labels of the scale marks 111 in the image captured by the remaining camera 20 from right to left are "line 2", "line 3", and "line 4" …, which do not meet the rule set by the central control unit 30, so that the central control unit 30 changes the labels of all scales originally labeled in the image captured by the camera 20 from "line" to "line (f-1)", where f is the original label value of each scale before changing one scale, and then the current adjustment value V of the adjustment knob 11 is Vp + Vu, Vp (n-1) — U, and Vu-U, so V is-nU; the central control unit 3 calculates the current adjustment value V when the adjustment knob 11 is rotated counterclockwise.

In practical use, each time the adjustment knob 11 of the scope 10 is rotated, referring to the execution flow of fig. 11, the camera 20 moves the scale mark 111 of the adjustment knob 11 of the scope 10 from left to right or from right to left, if a new scale mark appears in the rightmost field of view of the camera 20, the central control portion 30 immediately recognizes that it is a scale mark from its color and shape characteristics and analyzes its pixel position in the image captured by the camera 20, then determines that its position is rightmost in the image captured by the camera 20 from the comparison of the data of the pixel position of the scale mark and the data of the pixel positions of other scale marks, then determines that the scale mark 111 of the adjustment knob 11 of the scope 10 is rotated by a scale from the scale mark newly appearing in the rightmost field of view of the camera 20, since the newly appearing scale mark is located rightmost in the image captured by the camera 20, according to the rule, the central control unit 30 labels the label as "line 1", changes the labels of all scales originally labeled from "line" to "line (y + 1)", where y is the original label value of each scale before the change of one scale, then the current adjustment value V of the adjustment knob 11 is Vp + Vu, and Vu is U, so V is Vp + U, and the central control unit 30 records the value of V and transmits it to the display unit 40 for display, and then the next judgment execution process is performed. If the rightmost scale mark disappears from the image captured by the camera 20, since this scale mark is not in the visual field of the camera 20, that is, it is not in the identification area of the central control section 30, and the central control section 30 loses its identification, the central control section 30 immediately cancels its identification label, the label name of the scale mark, which is the identification target labeled "line 1", and the data such as the size and the pixel position thereof in the image captured by the camera 20 disappear from the system, and the central control section 30 immediately judges from these disappearing data that the scale mark 111 of the adjustment knob 11 of the scope 10 has been rotated counterclockwise by one scale mark, and since the scale mark "line 1" disappears from the image captured by the camera 20 at this time, the scale marks of the remaining images captured by the camera 20 are labeled "line 2" in the order from right to left, Since the central control unit 30 changes the labels of all scales originally labeled in the image captured by the camera 20 from "line" to "line (d-1)" and d is the original label value of each scale before the change by one scale, the current adjustment value V of the adjustment knob 11 is Vp + Vu and Vu is-U, and therefore V is Vp-U, and the central control unit 30 records the value of V and transmits it to the display unit 40 to be displayed, and then the next determination execution process is performed.

Since the adjustment value calculation of the present invention is started from the zero point, i.e., Vp is 0, the central control unit 30 can continuously perform the determination process shown in fig. 11 as long as the adjustment knob 11 of the scope 10 is continuously rotated, calculate the current adjustment value of the adjustment knob 11, and transmit the current adjustment value to the display unit 40 for display.

Therefore, the visual perception system of the invention can immediately digitize the adjustment amount of the adjusting knob 11 of the sighting telescope 10, so that a shooter can acquire the current adjustment values of the height adjusting knob 11a and the left and right adjusting knobs 11b of the sighting telescope 10 from the display screen 41 without removing eyes from the eyepiece 14 of the sighting telescope, thereby quickly sighting the adjusting knob 11 of the sighting telescope 10 while observing a target and greatly improving the shooting efficiency. Furthermore, the current setting value of the setting knob 11 of the digital sighting telescope 10 can also be used by other shooting intelligence apparatuses, so that the calculation result of the shooting intelligence apparatus is directly linked with the current setting value V of the sighting telescope 10, thereby making it possible to use more new intelligence apparatuses.
