Further detailed, complete explanation is done to the present invention combined with specific embodiments below.The following description is substantially only It is merely exemplary and is not intended to the limitation disclosure, application or purposes.

For this situation, as shown in Figure 1, servo-actuated display multi-curvature electronics rearview mirror system of the invention includes camera 170, display screen 180 and image integrate processing module 100, wherein it includes Image Acquisition mould that described image, which integrates processing module 100, Block 110, image interception module 120, image processing module 130, image display 140 and dynamic adjustment module 150, the figure As acquisition module 110, image interception module 120, image processing module 130, image display 140 are sequentially connected, dynamic is adjusted Mould preparation block 150 is connect with image processing module 130, image display 140 respectively.

Each functions of modules effect is as follows:

Image capture module 110, the real time image collection image data shot based on electronics rearview mirror camera 170；

Image interception module 120, based on 110 acquired image data of image capture module and actual vehicle signal choose to Display image data；

Image processing module 130, based on the image to be displayed data intercepted, according to predetermined ratio transversely or it is radial will be to Display image is cut into continuously arranged a number of partial image, and according to the instruction of dynamic adjustment module 150 to partial image Cutting adjust accordingly；

Image display 140 is modified processing to the image data received from image processing module 130, and according to Preset program shows corresponding partial image on display screen 180 with split screen mode；

Dynamic adjustment module 150, image procossing situation and actual vehicle signal based on image processing module 130, dynamic are adjusted The split screen quantity and split screen size of whole image display 140, and each partial image is projected accordingly according to pre-defined rule On split screen region.

In order to guarantee that electronics rearview mirror system operational security is reliable, selectively, image of the present invention integrates processing module also It may include image verification module, based on the initial data obtained from electronics rearview mirror camera and from image display 140 sampled datas received carry out data check, and the check results are fed back to image processing module 130 and carry out control tune It is whole.

Specifically, image capture module 110 is drawn for acquiring the video of electronics rearview mirror system camera shooting in real time Face signal, picture area collected are defined as video collection area A.Image interception module 120 is used to acquire in described image Interception display picture area B within the scope of the video collection area A that module 110 acquires, display picture area B are that final output is extremely schemed Picture range as shown in carrying out display module 140.Typically, the video acquisition of the camera shooting of electronics rearview mirror system The size of region A is greater than or is equal to the display picture area B, and the display picture area B can be in the video pictures A In the range of move up and down, with meet vehicle operation different scenes in picture display require.As shown in Fig. 2, described aobvious Show that picture area B can adjust variation with vehicle running state and operator demand in the range of video collection area A.

As shown in figure 3, electronics rearview mirror system of the invention is directed to, when image capture module 110 acquires video acquisition area After domain A and the interception of image interception module 120 show picture area B, image processing module 130 is based on 120 institute of image interception module Image to be displayed is cut into company along vertical longitudinal direction according to predetermined ratio by the image-region range of the display picture area B of interception Continue three parts image arranged in parallel, be respectively defined as the first main field-of-view image of image V1(), the second image V2(external expansion visual field Image) and third image V3(in expanded field of vision image), it is generally the case that the first image V1, the second image V2, third image V3 The ration of division be 4:4:2 or 5:3:2, thus realize image data level construct three parts display area, i.e. three curvature Display effect.In the present invention, the first image V1, the second image V2, third image V3 the ration of division be not limited only to it is above-mentioned Two special ratios, and can change in a certain range, as long as the image-region of main view open country and expanded field of vision meets correlation method Requirement in rule.

Wherein, the first image V1 mainly covers main view open country image range, and the second image V2, which is mainly covered, is distanced laterally from vehicle External expansion field-of-view image range, third image V3 mainly covers the interior expanded field of vision image of laterally adjacent vehicle, also will be exactly The image monitoring carried out for " vision dead zone " during large car above-mentioned turning.

In general, image processing module 130 carries out distortion correction for the first image V1, the second image V2, third image V3 Processing, and for the second image V2 and third image V3, other than distortion correction processing, image processing module 130 can also root Transverse compression or stretching are carried out to the second image V2 and third image V3 according to the control instruction of dynamic adjustment module 150, had later Body explanation.

As previously mentioned, dynamic adjustment module 150 can show according to 130 Duis of image processing module the cut place of picture area B Situation and traveling state of vehicle are managed, dynamic adjusts the split screen quantity and split screen size of image display 140.Specifically, when Image processing module 130 will show that picture area B is cut into 3 subgraphs, the first image V1, the second image V2 and third image When V3, the split screen quantity and split screen size of image display 140 are also set according to traveling state of vehicle.This is because only When Vehicular turn or lane change, the third image V3 for covering interior expanded field of vision just has display demand, when vehicle is in straight-going state When, driver only needs to observe the first image V1 of covering main view open country and the second image V2 in the covering external expansion visual field.

Vehicle is monitored according to preset program when dynamic adjustment 150 real-time reception vehicle sensor signal of module based on this When in straight travel state, as shown in figure 3, the split screen quantity of image display 140 is set as 2 along vertical longitudinal direction at this time It is a, it is respectively defined as the first split screen S1(main view open country display screen) and the second split screen S2(external expansion visual field display screen), setting first The ratio of split screen S1 size and the second split screen S2 size is 2:1 or 3:1, and split screen dimension scale is kept to immobilize, first There is fixed Video segmentation line to show between different curvature between split screen S1 and the display area of the second split screen S2 to distinguish Effect facilitates driver quickly to identify.

On this basis, will be through treated the first main field-of-view image of image V1(of image processing module 130) project One split screen S1(main view open country display screen) on, it is ensured that the main field-of-view image that the first image is shown is really undistorted, i.e. presentation main view is wild Display effect.Will be through treated the second image V2(external expansion field-of-view image of image processing module 130) project the second split screen S2(external expansion visual field display screen) on, that is, external expansion visual field display effect is presented, to show left and right on entire display screen The multi-curvature effect of splicing.As previously mentioned, image processing module 130 can be according to the control instruction of dynamic adjustment module 150 to the The carry out transverse compression or stretching of two image V2.

Specifically, it can control image display 140 determining split screen quantity according to dynamic adjustment module 150 Come to carry out image procossing to the second image V2 with split screen dimensional conditions.Under normal conditions, the size of the second split screen S2 can be less than One split screen S1, at this point, the second image V2 can be transversely compressed, to show the second image V2 in the size range of the second split screen S2 All images information, in the second split screen S2 generate the biggish extension display effect of curvature.

When vehicle is in the acceleration mode by low speed to high speed, quickly change since road conditions are relatively single, show picture, Excessive velocities lead to the high factor of time of driver's reaction requirement, and demand of the driver to main view open country is relatively large at this time, to expansion The demand for opening up the visual field is relatively small, is changed as a result, based on Vehicle Speed, and the first split screen S1 size of control incrementally increases, phase Ying Di, the second split screen S2 size gradually reduce, and the first split screen S1 and the second split screen S2 size are in controllably determining range Variation.The image projected on the first split screen S1 for the first image V1 of guarantee is really undistorted, can adjust increase by first accordingly Image V1 range, simultaneously because the second split screen S2 size reduces, correspondingly control improves the second image V2 transverse compression ratio, from And the multi-curvature display effect for the splicing that guarantees main view open country and expanded field of vision or so.

In the process, as the dynamic of the first split screen S1 and the second split screen S2 dimension scale adjusts, different zones are distinguished Between Video segmentation line can with vehicle condition change swing in a certain range, facilitate driver quickly to identify.

Correspondingly, when vehicle is in the deceleration regime by high speed to low speed, the first split screen S1 and the second split screen S2 size Changing than regular meeting along opposite mode dynamic adjustment, that is, the first split screen S1 size of control gradually reduces, correspondingly, second point Screen S2 size incrementally increases, and details are not described herein for concrete mode.

As shown in figure 4, being monitored when dynamic adjustment 150 real-time reception vehicle sensor signal of module according to preset program When vehicle is in turning or lane change state, the split screen quantity of image display 140 is become 3 according to same way, respectively Be defined as the first split screen S1(main view open country display screen), the second split screen S2(external expansion visual field display screen) and third split screen S3(in expand Open up visual field display screen), i.e., on the basis of aforesaid state, third split screen S3 is increased for showing interior expanded field of vision, monitoring is large-scale " vision dead zone " during vehicle turning.

As driver brought by turning or lane change state change occurs for vehicle to electronics rearview mirror main view open country, external expansion The changes in demand in the visual field and interior expanded field of vision, in this course of work, since initial straight-going state-turn to or lane change-turn To or lane change future-steering or lane change after journey-steering or lane change complete the split screen variation diagram in five stages, it can be seen that In Initial straight-going state is into steering or lane change starting process, and as vehicle corner increases activation threshold value, image display 140 is controlled Display screen processed is gradually become 3 panes (S1, S2, S3) from two split screens (S1, S2), and the first split screen S1 size of covering main view open country is protected Hold constant and display position translates, cover in the third split screen S3 of expanded field of vision gradually show and size also incrementally increases, Correspondingly, the second split screen S2 size for covering the external expansion visual field also gradually reduces, that is to say, that second point under 3 panes state Shield the second split screen S2 size that the sum of size of S2 and third split screen S3 is equal under two split screen states, that is, the ruler of third split screen S3 Very little incrementss are equal to the reduction amount of the second split screen S2 size.

During journey after vehicle is in steering or lane change future to steering or lane change, vehicle steering angle reaches maximum value When, the size of third split screen S3 increases to maximum value, and the second split screen S2's is reduced in size to minimum value, at this time as the time pushes away It moves, the entire steering procedure of vehicle is gradually completing, and the third split screen S3 size for covering interior expanded field of vision gradually reduces, and correspondingly, is covered The second split screen S2 size in the lid external expansion visual field incrementally increases, until after the completion of steering or lane change, vehicle image display module 140 Control display screen is gradually become two split screens from 3 panes, and third split screen S3 gradually disappears, and returns to working condition when original straight trip.

As shown in figure 4, the first split screen S1 and the second split screen S2, the first split screen S1 and third divide in the above-mentioned course of work Shielding has between the display area of S3 as vehicle body turns to the Video segmentation line of variation, and driver is facilitated quickly to identify.Wherein, first Split screen S1 concurrently sets the first split screen S1, the second split screen S2, third split screen S3 between the second split screen S2 and third split screen S3 Dimension scale substantially 6:3:1 or 6:2:2, maximum ratio limit value when above-mentioned dimension scale is turning or lane change state.Herein In range, those skilled in the art can carry out any adjustment to the ratio, as long as the video of main view open country and expanded field of vision is aobvious Show the requirement met in relevant laws and regulations.

Due to requiring the first split screen S1 size constancy and position translation, dynamic adjusts module 150 and controls the first image The image that V1 is projected on the first split screen S1 is really undistorted, only adjusts the first split screen S1's of translation by image display 140 Display position.Since the second split screen S2 size gradually reduces, correspondingly control improves the second image V2 transverse compression ratio, thus The expanded field of vision of second image V2 is more intuitively clearly illustrated on the second split screen S2 that size becomes smaller, is utmostly met Driver is during turning or lane change to the observation demand at rear or outside road conditions.Since the size of third split screen S3 gradually increases Add, control image processing module 130 to third image V3 carry out transverse compression after project on third split screen S3, as a result, with The size of third split screen S3 increases, and the compression factor of third image V3 can gradually reduce, and projects the display effect of third split screen S3 Fruit also gradually enhances, to guarantee interior expanded field of vision in electronics rearview mirror display screen, main view open country, the splicing of external expansion visual field left, center, right Display effect.

Similarly, in the process, with the first split screen S1, the second split screen S2, third split screen S3 dimension scale dynamic Two Video segmentation lines between different zones are distinguished in adjustment, the variation of mainly the second split screen S2 and third split screen S3 size Driver can be facilitated quickly to identify with vehicle turning or the turn signal of lane change sliding and swaying in a certain range.

It at this time include reversing steering and reversing straight trip two states, when reversing turns when vehicle is in reversing binning state Xiang Shi, the course of work of electronics rearview mirror are identical as basic process when above-mentioned turning or lane change.Specifically, oversize vehicle drives The observation of member's internal expanded field of vision road conditions when reversing turns to storage is more demanding, correspondingly, is turned to based on vehicle backing and vehicle Fast state can specifically be monitored anticipation by steering signal of vehicle, and controlling display screen from two split screens (S1, S2) gradually becomes three Split screen (S1, S2, S3) shows conditions of demand to the observation in the three parts visual field according to driver, covers main view in this course The first wild split screen S1 size remains unchanged and display position translates, and the third split screen S3 for covering interior expanded field of vision is gradually shown Now and size also incrementally increases, and correspondingly, the second split screen S2 size in the covering external expansion visual field also gradually reduces.

It completes when turning into when reversing straight trip, demand of the driver to main view open country is compared to expanded field of vision height, at this point, control Display screen processed gradually becomes two split screens (S1, S2) from 3 panes (S1, S2, S3), and the speed based on vehicle backing straight trip is controlled System adjustment, when reversing straight trip speed is lower, driver changes of less demanding, the first split screen S1 to the electronics rearview mirror visual field at this time It can be remained unchanged with the ratio of the second split screen S2 size, when reversing straight trip speed is higher, need of the driver to main view open country at this time Ask relatively large, the demand to expanded field of vision is relatively small, changes as a result, based on Vehicle Speed, controls the first split screen S1 Size incrementally increases, and the second split screen S2 size gradually reduces, and the first split screen S1 and the second split screen S2 size are controllably determining In the range of change, thus utmostly meet driver reversing turn to and reversing straight trip during to rear or outside road conditions Observation demand.Details are not described herein for detailed concrete mode, and specific control logic table is shown in Figure 5

The vehicle sensor signal includes the parameters such as driving status, travel speed, turn signal, interior wheelspan, the traveling State includes straight trip, reversing, steering, lane change, and the turn signal includes steering wheel turn signal, turns to modulating signal, wheel turn Dynamic angle etc..

Overview says it, and the present invention is by the first main field-of-view image of image V1() project the first split screen S1(main view open country display screen) On, main view open country display effect is presented, by the second image V2(external expansion field-of-view image) project the second split screen S2(external expansion visual field Display screen) on, by expanded field of vision image in third image V3() project expanded field of vision display screen in third split screen S3() on, point Inside and outside two class expanded field of vision display effects are presented in cloth, and third split screen S3, the first split screen S1 and the second split screen S2 are according to transverse direction as a result, Distribution mode splicing, it is seamless spliced between main view open country and inside and outside expanded field of vision, significantly improve vertical screen electronics in the prior art The defect spliced between main view open country and inside and outside expanded field of vision according to upper and lower mode in rearview mirror, can effectively monitor vehicle in real time " vision dead zone " during turning also avoids driver's duplicate acknowledgment object distance bring visual fatigue.

Multi-curvature electronics rearview mirror of the invention multiple split screen intersections in display screen show Video segmentation line, this energy Enough helping driver which side is differentiated is main view open country, which side is expanded field of vision, at the same time it can also help driver's accurate judgement vehicle At a distance from barrier or rear car, the generation for leading to traveling accident because observing the dizzy sense that rearview mirror generates is avoided.

It is important to note that those skilled in the art can clearly know on this basis, can be adjusted by dynamic Mould preparation block 150 and image processing module 130 control the quantity of subgraph and split screen to realize that the electronics rearview mirror of multi-curvature is shown Effect, concrete implementation mode and control logic are easy on the basis of electronics rearview mirror basic function disclosed by the invention real It is existing, belong to the scope that the present invention discloses protection.
