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 160, show mould based on the initial data obtained from electronics rearview mirror camera and from image The sampled data that block 140 receives carries out data check, and the check results are fed back to image processing module 130 and are controlled Adjustment.

Specifically, the video that image capture module 110 is shot for acquiring electronics rearview mirror system camera 170 in real time Picture signal, picture area collected are defined as video collection area A.Image interception module 120 in described image for adopting Collect module 110 acquire video collection area A in interception display picture area B, show picture area B be final output extremely The picture range that image display 140 is shown.Typically, the view that the camera 170 of electronics rearview mirror system is shot The size of frequency pickup area A is greater than or is equal to the display picture area B, and the display picture area B can be in the view It moves up and down in the range of frequency picture A, is required with meeting the picture display in vehicle operation different scenes.As shown in Fig. 2, The display picture area B can in the range of video collection area A with vehicle running state and Driver Vision demand and Adjustment variation.

As shown in figure 3, hyperbolicity electronics rearview mirror system is directed to, when image capture module 110 acquires video collection area A And after the interception display of image interception module 120 picture area B, image processing module 130 is based on image interception module 120 and is intercepted Display picture area B image-region range, according to predetermined ratio along it is vertical longitudinal image to be displayed is cut into it is continuous flat Two parts image of row arrangement, is respectively defined as the first main field-of-view image of image V1() and the second image V2(expanded field of vision figure Picture), it is generally the case that the ration of division of the first image V1 and the second image V2 are 1:1 to 3:2, to realize in picture number Two parts display area is constructed according to level.In general, image processing module 130 is abnormal for the first image V1 and the second image V2 progress Become correction process, and for the second image V2, other than distortion correction processing, image processing module 130 can also be according to dynamic The control instruction of module 150 is adjusted to the carry out transverse compression or stretching of the second image V2, is illustrated later.

As one of embodiments of the present invention, dynamic adjusts 150 real-time reception vehicle sensor signal of module, according to pre- When determining sequential monitoring and being in the straight travel state of average rate range to vehicle, control electronics rearview mirror be in that hyperbolicity is fixed to be shown Operating mode, at this point, dynamic adjustment module 150 according to 130 pairs of image processing module show picture area B cutting process feelings Condition, such as when image processing module 130 will show that picture area B is cut into 2 subgraphs, the first image V1 and the second image V2 When, the split screen quantity of image display 140 is set as 2 also according to identical cutting mode, is respectively defined as first point Shield S1(main view open country display screen) and the second split screen S2(expanded field of vision display screen), concurrently set the first split screen S1 size and second point The ratio for shielding S2 size is 2:1 or 3:1, and split screen dimension scale is kept to immobilize, in the first split screen S1 and the second split screen S2 Display area between have fixed Video segmentation line to distinguish display effect between different curvature, facilitate driver quick Identification.

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(expanded field of vision image of image processing module 130) project the second split screen S2 On (expanded field of vision display screen), that is, expanded field of vision display effect is presented, to show left and right splicing on entire display screen Hyperbolicity effect.As previously mentioned, image processing module 130 can be according to the control instruction of dynamic adjustment module 150 to the second image The carry out transverse compression of V2 or stretching.

Specifically, it can control image display 140 determining split screen quantity according to dynamic adjustment module 150 Come to carry out the second image V2 image procossing with split screen dimensional conditions, usually under the operating mode of the fixed display of hyperbolicity, the The size of 2 panes S2 can be less than the first split screen S1, at this point, the second image V2 can be transversely compressed, in the ruler of the second split screen S2 The all images information of the second image V2 of display in very little range generates the biggish extension display effect of curvature in the second split screen S2 Fruit.

It should be strongly noted that electronics rearview mirror can be constantly in the operating mode of the fixed display of hyperbolicity, at this point, can It closes relevant work scheme control to adjust, electronics rearview mirror operating mode is unrelated with vehicle-state.In addition, the fixed display of hyperbolicity The display scale of the first split screen and the second split screen when operating mode be it is fixed, also may be defined as hyperbolicity electronics rearview mirror Standard operating conditions.

As one of embodiments of the present invention, dynamic adjusts 150 real-time reception vehicle sensor signal of module, according to pre- When determining sequential monitoring and being in straight-line travelling acceleration or deceleration or steering or lane change or state of rolling backward to vehicle, electronics rearview mirror is controlled Operating mode in the servo-actuated display of hyperbolicity, at this point, the difference is that, being moved with the fixed display operating mode of aforementioned hyperbolicity State adjusts ratio of the module 150 based on vehicle condition the first split screen S1 size of setting and the first split screen S1 size in 2:1 to 5:1's Range dynamic change, above range are preferably 2:1 to 4:1.At this point, two split screen dimension scales not immobilize, but with Vehicle-state change brought by driver is wild to electronics rearview mirror main view and the changes in demand of expanded field of vision, dynamic adjust mould Block 150 dynamically adjusts the dimension scale of the first split screen S1 and the second split screen S2 of image display 140.

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 hyperbolicity 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 change sliding and swaying in a certain range with vehicle condition, 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, and specific control logic table is shown in Figure 4.

When vehicle is in turning or when lane change state, demand of the driver to expanded field of vision is required high at this time, to rear or The observation of outside road conditions is even more important, and correspondingly, the demand to main view open country becomes smaller relatively, is based on vehicle turning or lane change as a result, Steering degree, can specifically be monitored anticipation by steering signal of vehicle, the second split screen S2 size of control incrementally increases, accordingly Ground, the first split screen S1 size gradually reduce, and the first split screen S1 and the second split screen S2 size become in controllably determining range Change.The image projected on the first split screen S1 for the first image V1 of guarantee is really undistorted, can correspondingly adjust and reduce the first figure As V1 range, simultaneously because the second split screen S2 size increases, correspondingly control reduces 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 become large-sized, is utmostly met Driver is during turning or lane change to the observation demand at rear or outside road conditions.Similarly, in the process, with first The adjustment of the dynamic of split screen S1 and the second split screen S2 dimension scale, distinguishing the Video segmentation line between different zones can turn with vehicle Curved or lane change turn signal is swung in a certain range, and driver is facilitated quickly to identify.

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, demand of the driver to expanded field of vision require height, are even more important to the observation at rear or outside road conditions, correspondingly, to master The demand in the visual field is opposite to become smaller, and as a result, based on vehicle backing steering and speed state, can specifically be carried out by steering signal of vehicle Monitoring anticipation, the second split screen S2 size of control incrementally increase, and correspondingly, the first split screen S1 size gradually reduces, and the first split screen S1 and the second split screen S2 size change in controllably determining range.When reversing straight trip, demand of the driver to main view open country Compared to expanded field of vision height, at this point, the speed based on vehicle backing straight trip carries out control adjustment, when reversing straight trip speed is lower When, driver changes the electronics rearview mirror visual field of less demanding at this time, and the ratio of the first split screen S1 and the second split screen S2 size can It remains unchanged, when reversing straight trip speed is higher, demand of the driver to main view open country is relatively large at this time, to the need of expanded field of vision It asks relatively small, is changed as a result, based on Vehicle Speed, the first split screen S1 size of control incrementally increases, the second split screen S2 ruler It is very little to gradually reduce, and the first split screen S1 and the second split screen S2 size change in controllably determining range, thus utmostly Meet driver during reversing turns to and reversing is kept straight on to the observation demand at rear or outside road conditions.

The vehicle sensor signal includes the parameters such as driving status, travel speed, turn signal, interior wheelspan, described Driving status includes straight trip, reversing, turns to, lane change, and the turn signal includes steering wheel turn signal, turns to modulating signal, vehicle Take turns rotational 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(expanded field of vision image) it projects the second split screen S2(expanded field of vision and shows Screen) on, expanded field of vision display effect is presented, the first split screen S1 and the second split screen S2 splice according to cross direction profiles mode as a result, main It is seamless spliced between the visual field and expanded field of vision, significantly improve main view open country and extension in vertical screen electronics rearview mirror in the prior art The defect spliced between the visual field according to upper and lower mode avoids driver's duplicate acknowledgment object distance bring visual fatigue.

Hyperbolicity electronics rearview mirror of the invention two 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.For a left side Rearview mirror, line of demarcation left side are expanded field of vision, are the main visual field on the right side of line of demarcation；It is main view on the left of line of demarcation for right rear view mirror Open country, line of demarcation right side are expanded field of vision.

As previously mentioned, the ratio of the first split screen S1 and the second split screen S2 can be 2:1 to 5:1, it is therefore preferable to 2:1 to 4:1. The ratio is preferably not less than 2:1, because too small ratio is unfavorable for driver and differentiates main view open country and expanded field of vision, the ratio Preferably no greater than 5:1, because too big ratio causes the presence of expanded field of vision to lose meaning.Within this range, art technology Personnel can carry out any adjustment to the ratio, meet in relevant laws and regulations as long as the video of main view open country and expanded field of vision is shown It is required that.

It is important to note that above-mentioned only carried out the hyperbolicity effect of electronics rearview mirror to introduce description in detail, Those skilled in the art can clearly know on this basis, can adjust module 150 and image processing module 130 by dynamic The quantity of subgraph and split screen is controlled to realize the electronics rearview mirror display effect of three curvature or multi-curvature, concrete implementation mode With control logic on the basis of hyperbolicity electronics rearview mirror basic function disclosed by the invention it is easy to accomplish, correspondingly, three The electronics rearview mirror of curvature or multi-curvature belongs to the scope that the present invention discloses protection.

As one of embodiment of the present invention, the display screen of hyperbolicity electronics rearview mirror can shield for vertical screen or laterally. As shown in figure 5, the lateral rectangular rear-mirror mirror surface equally picture of two different focal lengths of tiled display in the same direction, the first display Main view is wild for rendering by region S1, the second display area S2 expanded field of vision for rendering.

As one of embodiments of the present invention, when using laterally screen, the vertical angle that image is shown is unsatisfactory for requiring. In such a case, it is possible to which the mode spliced up and down is used to provide the broader visual field for driver.

As previously mentioned, electronics rearview mirror camera is abnormal because of sensor or electrical part in the prior art, or because high Picture is handled and cannot be met the requirements speed when driving, and the failures such as appearance influence is freezed, the even unexpected blank screen of picture delay exist very More security risks.

As another aspect of the present invention, the image of the hyperbolicity electronics rearview mirror integrates processing module 100 and may be used also To include image verification module 160, 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.For example, if video image movement speed it is smaller than speed or speed is not zero and picture solidification it is motionless, judge that picture goes out Now freeze or postpone, at this point, image verification module issues sound-light alarm prompt to image display 140.

It should be strongly noted that hyperbolicity electronics rearview mirror of the invention can be applied to a variety of vehicles, including But be not limited to automobile, engineering truck, ship, bus, cleaning vehicle, logistic car, caravan, commercial vehicle etc..Rearview mirror is shown Image can change with the direction change for using main body to provide, and realize that scene is servo-actuated.

Above-mentioned specific embodiment, does not constitute a limitation on the scope of protection of the present invention.Those skilled in the art should be bright It is white, design requirement and other factors are depended on, various modifications, combination, sub-portfolio and substitution can occur.It is any Made modifications, equivalent substitutions and improvements etc. within the spirit and principles in the present invention, should be included in the scope of the present invention Within.
