Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The thermal imaging sight that this application embodiment provided, as shown in fig. 1, the thermal imaging sight includes: the device comprises a machine body 1, an ocular 2 and a part to be measured 3; the part to be measured 3 is fixed on the ocular 2, and the machine body 1 is detachably connected with the ocular 2; the machine body 1 is provided with an image acquisition assembly 11, a controller 12, a display 13 and a detection component 14; the controller 12 is electrically connected with the image acquisition assembly 11, the display 13 and the detection part 14 respectively;

the image acquisition component 11 is used for transmitting each continuously acquired image data to the controller 12;

the detection component 14 is used for detecting the component 3 to be detected, obtaining detection information and transmitting the detection information to the controller 12;

the controller 12 is configured to determine a target image adjustment manner corresponding to the detection information detected by the detection component 14 according to a preset correspondence between the detection information and the image adjustment manner; adjusting each image data continuously acquired by the image acquisition assembly 11 based on the target image adjustment mode, and transmitting the adjusted image data to the display 13;

and a display 13 for displaying the adjusted image data.

In an implementation, the image capturing component 11 may transmit the captured image data to the controller 12, the image data captured by the image capturing component 11 may be an image signal, and the controller 12 may process the electrical signal into the image data. For example, an AD conversion unit and an image processing unit may be included in the controller 12, and the AD conversion unit may convert an analog signal (image signal) sent by the image capturing assembly 11 into a digital signal, and then process the digital signal into image data for display by the display 13 via the image processing unit. The controller 12 can also receive the detection information corresponding to the detected part 3 fixed on the eyepiece 2 and detected by the detection part 14, and determine the corresponding target image adjustment mode in the preset corresponding relationship between the detection information and the image adjustment mode. Then, each continuously acquired image data is adjusted according to the target image adjustment mode, and the adjusted image data is transmitted to the display 13 for display.

Alternatively, the component to be detected 3 includes a magnet 31, and the detecting component 14 includes a hall sensor 141.

In implementation, the detected component 3 may be a magnet 31, and the corresponding detecting component 14 may be a hall sensor 141. Whether the hall sensor 141 detects the magnetic field of the magnet 31 or the direction of the magnetic field of the magnet 31 detected by the hall sensor 141 may be used as the detection information.

When the hall sensor 141 uses the magnetic field direction of the magnet 31 detected by the hall sensor 141 as detection information, the thermal imaging sight includes a plurality of magnets 31, the main body 1 is provided with a plurality of hall sensors 141, and the number of the plurality of magnets 31 is equal to the number of the plurality of hall sensors 141.

The hall sensor 141 is configured to detect a magnetic field direction of the corresponding magnet 31, determine a first value as detection information if the magnetic field direction of the corresponding magnet 31 is detected as a first magnetic field direction, and determine a second value as detection information if the magnetic field direction of the corresponding magnet 31 is detected as a second magnetic field direction; the controller 12 is configured to determine a target image adjustment manner corresponding to the received multiple pieces of detection information sent by the multiple hall sensors 141 according to a preset correspondence between the detection information combinations and the image adjustment manners.

In practice, the orientation of the N pole or S pole of the magnet 31 fixed to the eyepiece can be set to be the same for the same magnification or type of magnification, so that the magnification or type of the eyepiece can be determined by detecting the direction of the magnetic field of the magnet 31 fixed to the eyepiece. Since the hall sensor 141 can detect two magnetic field directions corresponding to one magnet 31, as shown in fig. 2, the first magnetic field direction is a magnetic field direction directed from the magnet 31 to the hall sensor 141, and the second magnetic field direction is a magnetic field direction directed from the hall sensor to the magnet 31. It is possible to distinguish between the two eyepieces by the direction of the magnetic field if only one magnet 31 is fixed in the eyepiece. In practical application, different magnifications and kinds of eyepieces exist, so that the number of eyes can be increasedThe number of magnets 31 fixed to the mirror corresponds to different eyepieces by combination of magnetic field directions corresponding to the plurality of magnets 31. For example, if 2 magnets 31 are fixed in the eyepiece, 2 magnets 31 can form 4 different combinations of magnetic field directions, and thus 4 different magnifications of the eyepiece can be distinguished, and correspondingly if n magnets 31 are fixed in the eyepiece, n magnets 31 can form 2ⁿDifferent combinations of magnetic field directions can be distinguished 2ⁿDifferent magnifications of the eyepiece.

Accordingly, as the number of the magnets 31 increases, the number of the hall sensors 141 may also increase, and the number of the hall sensors 141 is equal to the number of the magnets 31. So that each hall sensor 141 on the body 1 can detect the magnetic field direction of the corresponding magnet 31. When the first magnetic field direction is detected, the first numerical value is determined as the detection information, and if the magnetic field direction of the corresponding magnet 31 is detected as the second magnetic field direction, the second numerical value is determined as the detection information. Each hall sensor 141 may send the corresponding first value and second value to the controller 12, and the controller 12 may determine, according to a correspondence between a preset detection information combination and an image adjustment manner, a target image adjustment manner corresponding to a plurality of pieces of detection information sent by the received plurality of hall sensors 141. Wherein each image adjustment may correspond to an eyepiece of unique magnification. For example, the first value is 1, the second value is 0, and the number of magnets 31 is 2, and table 1 can be a type of eyepiece corresponding to the output of the hall sensor, as shown in table 1.

TABLE 1

Optionally, the body 1 is further provided with a triode 18 and a power supply 19; the hall sensor 141 is electrically connected with the base electrode of the triode 18; the emitter of the transistor 18 is electrically connected to the positive electrode of the power supply 19, and the collector of the transistor 18 is electrically connected to the controller 12.

As shown in fig. 3, H1 and H2 are hall sensors, T1 and T2 are magnets, Q1 and Q2 are triodes, and BT1 is a power supply. Taking H1 as an example, after the eyepiece 2 is mounted on the body 1, the position of the magnet T1 fixed on the eyepiece 2 may correspond to the position of the hall sensor H1. When the magnet T1 is aligned with the hall sensor H1 with the S pole and the N pole, respectively, a0 may output a high level or a low level according to a conduction state with the triode.

In another possibility, when determining whether the hall sensor 141 detects the magnetic field of the magnet 31 as the detection information, the thermal imaging sight includes at least one magnet 31, and the main body 1 is provided with a plurality of hall sensors 141.

A plurality of positions of the fixed magnets 31 may be provided on the eyepiece 2, and a hall sensor 141 may be provided on the body 1 at positions corresponding to the plurality of fixed magnets 31. For the same magnification or kind of eyepiece, it is optional to fix the magnet 31 in the same fixed position. The plurality of hall sensors 141 may be configured to detect the magnetic field of the magnet 31, respectively, and determine a first value as detection information if the magnetic field of the magnet 31 is detected, and determine a second value as detection information if the magnetic field of the magnet 31 is not detected; the controller 12 is configured to determine a target image adjustment manner corresponding to the received multiple pieces of detection information sent by the multiple hall sensors 141 according to a preset correspondence between the detection information combinations and the image adjustment manners. For example, 3 positions of the fixed magnet 31 are provided on the eyepiece 2. The positions of the different kinds of eyepiece fixing magnets 31 may be different for the three different kinds of eyepieces, so that the kinds of the eyepieces can be determined based on the hall sensors 141 that detect the magnetic fields.

Optionally, the image capturing assembly 11 includes an objective 111 and an infrared sensor 112, and the infrared sensor 112 is electrically connected to the controller 12.

In an implementation, the image capturing assembly 11 may be composed of an objective lens 111 and an infrared sensor 112, and the infrared sensor 112 may be an infrared focal plane array. The objective lens 111 may focus external (thermal radiation) infrared rays on the infrared focal plane array, and the infrared focal plane array generates an electric signal (analog signal) from the detected infrared rays, and then transmits the electric signal to the controller 12, and then the electric signal is processed into image data by the controller 12.

Wherein the image adjustment mode comprises at least one of zooming, rotating and cutting.

In practice, the size of the corresponding observable area in the display 13 may be different due to the different magnifications of the different eyepieces, and the image (the image in the display 13) viewed when the magnification of the eyepiece is 1 time is an erect image, and the image viewed when the magnification of the eyepiece is high, such as 3 times and 5 times is an inverted image. Therefore, when the body of the thermal imaging sight is connected with different eyepieces, image data displayed on the display needs to be processed. The corresponding image processing mode can be set according to the magnification of the ocular, for example, when the ocular is high, the image can be rotated by 180 degrees and cut to the observable area of the high-power lens objective, or the image can be zoomed to the observable area of the high-power lens objective.

Optionally, as shown in fig. 4, a clamping groove 15 is arranged on the body 1, and a buckle 21 is arranged on the eyepiece 2; when the machine body 1 and the ocular lens 2 are tightly connected, a buckle 21 arranged on the ocular lens 2 is clamped with a clamping groove 15 arranged on the machine body 1; when the latch 21 is latched to the latch slot 15, the detection member 14 faces the member to be detected 3.

In practice, the body 1 and the eyepiece 2 may be detachably connected. For example, the body 1 and the eyepiece 2 may be connected by a screw thread. When the machine body 1 and the ocular 2 are tightly connected, the buckle 21 arranged on the ocular 2 can be clamped in the clamping groove arranged on the machine body. When the latch 21 is engaged with the slot 15, the position of the detection component 14 in the body may be opposite to the position of the detected component 3. Thus, the detection unit 14 can accurately detect the detection information corresponding to the detected member 3. This makes it possible to distinguish different eyepieces 2 by the detection information.

Optionally, as shown in fig. 5, a detection contact 17 is arranged on the body 1, a detected contact 22 is arranged on the eyepiece 2, and the detection contact 17 corresponds to the detected contact 22; the controller 12 is electrically connected with the detection contact 17; when the body 1 is connected with the ocular lens 2, the detection contact 17 is contacted with the detected contact 22; the controller 12 is further configured to control the detection component 14 to be turned on when the detection contact 17 is detected to be in contact with the detected contact 22, and control the detection component 14 to be turned off after the detection component 14 is turned on for a first preset time period.

In an embodiment, the body 1 may be provided with the detection contactor 17, and the eyepiece 2 may be provided with the detection contactor 22. Thus, when the eyepiece 2 is mounted on the body 1, the detection contact 17 can be brought into contact with the detection contact 22. The controller 12 can determine that the eyepiece 2 is mounted on the front body 1 when the detection contact 17 is in contact with the detected contact 22, and can control the detection component 14 to be opened so as to detect the detection information corresponding to the detected component 3 fixed on the eyepiece 2. The detection member 14 may then be controlled to turn off after the detection member 14 is turned on for a first preset period of time, which may be preset by a technician. Therefore, the detection component 14 is started within the first preset time length when the machine body 1 and the ocular lens 2 just start to be connected, and the detection component 14 does not need to be started all the time to detect the detection information corresponding to the detected component 3 fixed on the ocular lens 2.

Optionally, the controller 12 is further configured to control the display 13 to display an image adjustment failure prompt message if the target image adjustment manner corresponding to the detection information of the detected component 3 detected by the detection component 14 is not included in the corresponding relationship between the preset magnetic field direction and the image adjustment manner.

In implementation, when the detection information corresponding to the detected component 3 detected by the detection component 14 is not in the preset corresponding relationship, that is, if the controller 12 does not find the target image adjustment mode of the detection information corresponding to the detected component 3 detected by the detection component 14 in the corresponding relationship, the controller 12 may control the display 13 to display the image adjustment failure prompt information. The display image adjustment failure prompt message may be a sentence, for example, "do not store the image adjustment mode corresponding to the currently installed eyepiece, please manually adjust". In addition, since there is no target image adjustment method corresponding to the current eyepiece, the user may blur the image displayed on the display 13 when looking through the eyepiece, so the image adjustment failure prompt information may also be a symbol or a set color.

Optionally, the body 1 further comprises at least one key 16; at least one key 16 electrically connected to the controller 12; at least one key 16 is used to control the controller 12 to adjust the image data.

In implementation, the display 13 may display the prompt information of failure to adjust the image, and the user may manually adjust the image in the display 13, and the corresponding main body 1 may further be provided with at least one key 16, so that the user may control the controller 12 to adjust the image data through the at least one key 16.

Wherein, the at least one key 16 includes an adjustment key 161, a confirmation key 162 and an adjustment mode selection key 163; the controller 12 is further configured to control the image displayed on the display 13 to rotate by 180 degrees when detecting a single click of the adjustment mode selection key 163; after detecting that the adjustment mode selection key 163 is clicked twice continuously and when detecting that the adjustment key 161 is clicked within a second preset duration, controlling the scaling factor to change periodically according to a preset change rule, performing scaling adjustment on continuously acquired image data based on the scaling factor that changes periodically, and stopping the periodic change of the scaling factor after detecting that the confirmation key 162 is clicked during the periodic change of the scaling factor; after three continuous clicks of the adjustment mode selection key 163 are detected and when the click of the adjustment key 161 is detected within a second preset time period, the cutting size is controlled to periodically change according to a preset cutting rule, the image data continuously acquired is scaled and adjusted based on the periodically changed cutting size, and in the process of periodically changing the cutting size, the periodic change of the cutting size is stopped after the click of the confirmation key 162 is detected.

In implementation, the at least one key 16 includes an adjustment key 161, a confirmation key 162, and an adjustment mode selection key 163. Wherein the adjustment mode selection key 163 may be used to select an image adjustment mode. When the controller 12 detects that the adjustment mode selection key 163 is clicked a single time, it may be determined that the user selects the image rotation adjustment mode; when the controller 12 detects that the adjustment mode selection key 163 is continuously clicked twice, it may be determined that the user selects the image scaling adjustment mode; when the controller 12 detects that the adjustment mode selection key 163 is clicked three times in succession, what may be selected by the determination user is the image cropping adjustment mode. It should be noted that, a single click of the adjustment mode selection key 163 means that the adjustment mode selection key 163 is not detected to be clicked again within a preset click duration after the adjustment mode selection key 163 is clicked once, and a continuous click of the adjustment mode selection key 163 twice means that the adjustment mode selection key 163 is detected to be clicked again within a preset click duration after the adjustment mode selection key 163 is clicked once. The adjustment mode selection key 163 being clicked three times in succession means that it is detected that the adjustment mode selection key 163 is clicked twice again within a preset click duration after it is detected that the adjustment mode selection key 163 is clicked once.

(1) When the controller 13 detects a single click of the adjustment mode selection key 163, the image displayed in the display 13 may be controlled to be rotated by 180 degrees.

(2) When the controller 13 detects that the adjustment mode selection key 163 is clicked twice consecutively and detects that the adjustment key 161 is clicked within a second preset time period after detecting that the adjustment mode selection key 163 is clicked twice consecutively, the controller controls the scaling factor to change periodically according to a preset change rule, and then performs scaling adjustment on the image data that is continuously acquired according to the scaling factor that changes periodically. For example, the scaling factor may become larger over time, and may jump to the smallest scaling factor when the scaling factor reaches a maximum and then become larger over time. During the periodic variation of the scaling factor, the controller 12 may scale the current resulting image data according to the current scaling factor. It can be shown in the display 13 as an image that is periodically zoomed. The user can observe the periodically zoomed image displayed in the display 13 through the eyepiece 2 and can click the confirmation key 162 when the image is zoomed to an appropriate size. When the controller 12 detects that the confirmation key 162 is clicked, the controller 12 may stop the periodical change of the zoom factor, that is, the controller 12 zooms the image data according to the currently determined zoom factor.

(3) When the controller 13 detects that the adjustment mode selection key 163 is clicked three times in succession and detects that the adjustment key 161 is clicked within a second preset duration after detecting that the adjustment mode selection key 163 is clicked two times in succession, the controller controls the cropping size to change periodically according to a preset cropping rule, and then performs cropping adjustment on the image data which is continuously acquired according to the periodically changing cropping size. For example, the cut size may become larger gradually with time, and when the cut size reaches a maximum, the cut size may jump to a minimum cut size and then become larger gradually with time. During the process in which the cropping size periodically changes, the controller 12 may crop the current resulting image data according to the current cropping size. It can be displayed in the display 13 as a periodic cropping of the image. The user can observe the periodically cropped image displayed in the display 13 through the eyepiece 2 and can click the confirmation button 162 when the image is cropped to an appropriate size. When the controller 12 detects that the confirmation key 162 is clicked, the controller 12 may stop the periodical change of the cropping size, that is, the controller 12 crops the image data in the currently determined cropping size.

In addition, when there is no image adjustment mode corresponding to the current eyepiece for the preset correspondence between the magnetic field direction and the image adjustment mode, after the user adjusts the zoom size or the crop size corresponding to the current eyepiece through the at least one key 16, or determines whether to rotate, the corresponding image adjustment mode and the detected magnetic field direction of the magnet of the current eyepiece may be added to the preset correspondence between the magnetic field direction and the image adjustment mode.

The utility model provides a through fixed surveyed part on the eyepiece, when the fuselage of eyepiece and thermal imaging sight is connected, the detection part that sets up on the fuselage can detect the detection information that surveyed part on the eyepiece corresponds, then the controller can confirm the image adjustment mode that corresponds according to the detection information that the detection part detected, can distinguish different eyepieces through different detection information like this, and can confirm the target image adjustment mode of the current eyepiece that corresponds, then can adjust image data according to target image adjustment mode, thereby can make the user pass through the clear image that observes and shows in the display of eyepiece. It is thus clear that this application of adoption does not need the manual image adjustment operation of user, can improve the user and follow the efficiency of changing the eyepiece to can use the eyepiece to observe the image.
