Description

Technical Field

[0001] The present application relates to the field of automotive intelligent cockpit components, and particularly to a design method, device, equipment and storage medium for an anti-disturbance mechanism for rearview mirror vision. Background Art

[0002] Currently, most of the external rearview mirrors on automobiles are traditional optical rearview mirrors. The traditional optical rearview mirrors placed outside the vehicle are vulnerable to adverse weather conditions. For example, in rainy or snowy days, the vision reflected by the mirror surface will be affected. In the night or dim environment, the traffic conditions in the dark cannot be seen clearly. After the line of sight is disturbed, there will inevitably be traffic hazards.

[0003] In addition, traditional optical rearview mirrors are also prone to strong light irradiation from the front and rear during night driving, resulting in unclear vision and inability to obtain the rearview of the vehicle in time, interfering with normal driving. Seriously, when the driver observes the rear situation from the traditional optical rearview mirror, it may even cause the driver to be dazzled and blind, and it takes at least 1-2 seconds of reaction time to see the road conditions clearly. If the vehicle speed is relatively fast or there is an emergency situation ahead at this time, it is difficult for the driver to take timely measures to avoid the danger, affecting the safe driving of the driver.

[0044] In order to enable those skilled in the art of the present technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0045] To make the purpose, technical solution and advantages of this application clearer, the embodiments of this application will be further described in detail below with reference to the drawings.

[0046] In a first aspect, an embodiment of this application provides a design method for a rearview mirror vision anti-disturbance mechanism.

[0047] In one embodiment, referring to Figure 1 , Figure 1 is a schematic flowchart of the first embodiment of the design method for the rearview mirror vision anti-disturbance mechanism of this application. As Figure 1 shown, the rearview mirror vision anti-disturbance mechanism includes a first display screen 11 and a second display screen 12 installed inside the vehicle, and a first imaging device 21 installed at the rearview mirror installation position of the vehicle and electrically connected to the first display screen 11, and a second imaging device 22 electrically connected to the second display screen 12. The design method for the rearview mirror vision anti-disturbance mechanism includes:

[0048] S1: Based on the installation positions of the first display screen 11 and the second display screen 12 relative to the reference eye point 3, calculate the horizontal and vertical average magnification ratios of the physical object captured by the first imaging device 21 and displayed on the first display screen 11 from the perspective of the reference eye point 3, and the horizontal and vertical average magnification ratios of the physical object captured by the second imaging device 22 and displayed on the second display screen 12.

[0049] S2: Determine whether the average magnification ratios in the horizontal and vertical directions calculated both meet the requirements. If so, it is qualified; otherwise, it is unqualified. In the embodiments of the present application, both the first imaging device 21 and the second imaging device 22 can be set as cameras. The first imaging device 21 and the first display screen 11 can be installed near the driver's side, while the second imaging device 22 and the second display screen 12 are installed near the passenger's side. Preferably, the optical field of view of a traditional external rearview mirror is almost fixed, with a limited visible range and certain blind spots. However, the viewing angle of a camera can obtain a wider field of view with the help of a wide-angle lens. It is reported that when a single lane can only be seen in an ordinary physical rearview mirror, a wide-angle camera can view at least three lanes, changing the field-of-view limitation caused by factors such as the mirror curvature, shape, size, and angle of a traditional optical external rearview mirror.

[0050] In the embodiments of the present application, by installing the first imaging device 21 and the second imaging device 22 at the installation positions of vehicle rearview mirrors, and installing the first display screen 11 and the second display screen 12 electrically connected to the first imaging device 21 and the second imaging device 22 respectively inside the vehicle, the first imaging device 21 and the second imaging device 22 can be used to collect the fields of view on the left and right sides of the vehicle. The collected fields of view can be transmitted to the first display screen 11 and the second display screen 12 respectively. Since the first display screen 11 and the second display screen 12 are both installed inside the vehicle, the interference of the external environment on the first display screen 11 and the second display screen 12 used for observation is reduced. And calculate the average magnification ratios in the horizontal and vertical directions of the physical object captured by the first imaging device 21 and displayed on the first display screen 11, and the average magnification ratios in the horizontal and vertical directions of the physical object captured by the second imaging device 22 and displayed on the second display screen 12 from the perspective of the reference eye point 3. It should be understood that when determining that the average magnification ratios in each direction meet the requirements, it can be considered that the driver has a good viewing angle whether looking at the first display screen 11 or the second display screen 12, solving the technical problems in the related art that a traditional optical rearview mirror placed outside the vehicle is vulnerable to bad weather, and when the traditional optical rearview mirror is irradiated by strong light from the front and back, it affects the driver's safe driving. In addition, the rearview mirror field-of-view anti-interference mechanism in the embodiments of the present application can effectively prevent the field of view from being disturbed and improve the safety of night driving through its all-weather ability, high-definition display, and night vision ability.

[0051] Further, in one embodiment, calculating the average magnification ratios in the horizontal and vertical directions of the physical object captured by the first imaging device 21 and displayed on the first display screen 11, and the average magnification ratios in the horizontal and vertical directions of the physical object captured by the second imaging device 22 and displayed on the second display screen 12 from the perspective of the reference eye point 3 based on the installation positions of the first display screen 11 and the second display screen 12 relative to the reference eye point 3 includes:

[0052] S11: Taking the reference eye point 3 as the origin, measure the vertical installation angle θ of the first display screen 11 and the second display screen 12 monitor / ver / D and the horizontal installation angle θ monitor / hor / D , and measure the distance between the reference eye point 3 and the first display screen 11 and the distance a between the reference eye point 3 and the second display screen 12 monitor / D . The distance from the reference eye point 3 to the first display screen 11 can be the distance from the reference eye point 3 to the midpoint of the first display screen 11, and the distance between the reference eye point 3 and the second display screen 12 can also be the distance from the reference eye point 3 to the second display screen 12.

[0053] S12: Obtain the horizontal field of view angle α of the first imaging device 21 and the second imaging device 22 camera / hor and the vertical field of view angle α camera / ver . That is, the horizontal field of view angle of the first imaging device 21 and the second imaging device 22 is α camera / hor , and the vertical field of view angle of the first imaging device 21 and the second imaging device 22 is α camera / ver .

[0054] S13: Respectively obtain the horizontal field of view percentage p of the first imaging device 21 displayed on the first display screen 11 and the second imaging device 22 displayed on the second display screen 12 camera / hor , and obtain the vertical field of view percentage p of the first imaging device 21 displayed on the first display screen 11 and the second imaging device 22 displayed on the second display screen 12 camera / ver .

[0055] S14: Respectively obtain the size W of the first display screen 11 and the second display screen 12 in the horizontal direction monitor / hor and the size H in the vertical direction monitor / ver . It should be understood that the horizontal direction and the vertical direction at this time can refer to the horizontal and vertical directions of the first display screen 11 and the second display screen 12 themselves. When the first display screen 11 and the second display screen 12 are installed in the vehicle, the plate surface direction thereof may not be perpendicular to the vehicle length direction in the X direction of the vehicle, that is, the plate surfaces of the first display screen 11 and the second display screen 12 both have a certain included angle with the vehicle length direction. In the embodiments of the present application, the size of the first display screen 11 in the horizontal direction is the horizontal width of the first display screen 11 itself, and the size in the vertical direction is the longitudinal length. Similarly, the horizontal direction size and the vertical direction size of the second display screen 12 are respectively the horizontal width and the longitudinal length of the second display screen 12 itself. It should be understood that the above-mentioned horizontal width and longitudinal width only include the screen sizes of the first display screen 11 and the second display screen 12, and do not include the outer frame.

[0056] S15: Based on the horizontal installation angle θ monitor / hor / D , distance a monitor / D , horizontal field of view angle αcamera / hor and the percentage p of the field of view camera / hor and the size W monitor / hor , calculate the horizontal average magnification of the physical object captured by the first imaging device 21 when viewed from the reference eye point 3 and displayed on the first display screen 11 and the second display screen 12; based on the vertical installation angle θ monitor / ver / D , the distance a monitor / D , the vertical field of view angle α camera / ver , p camera / ver and the size H monitor / ver , calculate the vertical average magnification of the physical object captured by the first imaging device 21 when viewed from the reference eye point 3 and displayed on the first display screen 11 and the second display screen 12. In the embodiments of the present application, in the steps S11 to S14, the acquisition times of the respective data can be interchanged, that is, it is not necessary to acquire the respective data in a certain order, and even the respective data can be acquired synchronously.

[0057] In this embodiment, by using the respective data that can be directly measured or directly obtained, calculate the horizontal and vertical average magnifications of the physical object captured by the first imaging device 21 when viewed from the reference eye point 3 and displayed on the first display screen 11, and the horizontal and vertical average magnifications of the physical object captured by the second imaging device 22 and the image displayed on the second display screen 12, and make the picture content parameters of the first display screen 11 and the second display screen 12 as close as possible for the driver to see through the calculation results, which can solve the technical problem of the long visual adaptation time for the driver when switching between different display screens during driving in the related art.

[0058] Further, in one embodiment, as shown in Figure 3 , taking the reference eye point 3 as the origin, measuring the vertical and horizontal installation angles of the first display screen 11 and the second display screen 12 may include: prescribing a line extending along the length direction of the vehicle from the reference eye point 3 as the main line of sight; denoting the line connecting the reference eye point 3 and the center of the first display screen 11 as the first line, and the line connecting the reference eye point 3 and the center of the second display screen 12 as the second line, measuring the vertical and horizontal installation angles between the main line of sight and the first line as the vertical and horizontal installation angles of the first display screen 11, and measuring the vertical and horizontal installation angles between the main line of sight and the second line as the vertical and horizontal installation angles of the second display screen 12. The acquisition of the vertical and horizontal installation angles can be based on the driver's sitting position as the origin, respectively radiating forward to the first display screen 11 and the second display screen 12, and according to the radiation lines, calculating the vertical installation angle θ monitor / ver / D and the horizontal installation angle θ monitor / hor / DIn the embodiments of the present application, measuring the angle between the main line of sight and the first connection line or the second connection line in the vertical direction reflects the inclination degree of the first display screen 11 or the second display screen 12 relative to the driver's line of sight along the Z-axis (the up-and-down direction of the vehicle); measuring the angle between the main line of sight and the first connection line or the second connection line in the horizontal direction reflects the deflection degree of the first display screen 11 or the second display screen 12 relative to the driver's line of sight along the Y-axis (the left-and-right direction of the vehicle).

[0059] In this embodiment, by prescribing the main line of sight and prescribing the first connection line and the second connection line respectively, the vertical installation angle θ monitor / ver / D and the horizontal installation angle θ monitor / hor / D between the main line of sight and the first connection line can be obtained relatively quickly and intuitively, and the technical problem of the complex measurement process of the vertical and horizontal installation angles of the first display screen 11 and the second display screen 12 in the related art is solved.

[0060] Further, in one embodiment, before calculating the horizontal average magnification of the physical object captured by the first imaging device 21 and displayed on the first display screen 11 and the second display screen 12 from the perspective of the reference eye point 3 based on the horizontal installation angle θ monitor / hor / D , distance a monitor / D , horizontal field of view angle α camera / hor , percentage p of the field of view camera / hor and size W monitor / hor , it includes: constructing the horizontal angular size α′ monitor / hor / D of the first display screen 11 and the second display screen 12, and the horizontal display size α monitor / hor of the images of the first display screen 11 and the second display screen 12, and the relationship formula with the horizontal average magnification M system / hor / avg of the physical object captured by the first imaging device 21 and displayed on the first display screen 11 or the physical object captured by the second imaging device 22 and displayed on the second display screen 12 from the perspective of the reference eye point 3, which is denoted as the first formula; based on the first formula, constructing the relationship formula between the horizontal installation angle θ monitor / hor / D , distance a monitor / D , horizontal field of view angle α camera / hor , percentage p of the field of view camera / hor and size W monitor / hor and the horizontal average magnification M system / hor / avg . In the embodiments of the present application, the constructed first formula can be denoted as:

[0061] Further, in one embodiment, based on the vertical installation angle θ monitor / ver / D , distance a monitor / D , vertical field of view angle α camera / ver , pcamera / ver and dimension H monitor / ver , before calculating the vertical average magnification of the object captured by the first imaging device 21 and displayed on the first display screen 11 and the second display screen 12 from the perspective of the reference eye point 3, it may further include: constructing the vertical angular dimension α' of the first display screen 11 and the second display screen 12 monitor / ver / D , and the vertical image display dimension α of the first display screen 11 and the second display screen 12 monitor / ver and the vertical average magnification M of the object captured by the first imaging device 21 and displayed on the first display screen 11 or the object captured by the second imaging device 22 and displayed on the second display screen 12 from the perspective of the reference eye point 3 system / ver / avg The relational expression is denoted as the second formula; based on the second formula, the vertical installation angle θ monitor / ver / D , distance a monitor / D , vertical field of view angle α camera / ver , p camera / ver and dimension H monitor / ver and the vertical average magnification M system / ver / avg The relational expression. The constructed second formula can be denoted as:

[0062] It should be understood that the horizontal average magnification of the object captured by the first imaging device 21 and displayed on the first display screen 11 and the horizontal average magnification of the object captured by the second imaging device 22 and displayed on the second display screen 12 from the perspective of the reference eye point 3 can be denoted as M system / hor / avg , specifically:

[0063]

[0064] The vertical average magnification of the object captured by the first imaging device 21 and displayed on the first display screen 11 and the vertical average magnification of the object captured by the second imaging device 22 and displayed on the second display screen 12 from the perspective of the reference eye point 3 can be denoted as M system / ver / avg , specifically:

[0065]

[0066] In this embodiment, by constructing the first formula and the second formula, a basis is provided for calculating the horizontal and vertical average magnifications of the object captured by the first imaging device 21 and displayed on the first display screen 11 and the horizontal and vertical average magnifications of the object captured by the second imaging device 22 and displayed on the second display screen 12 from the perspective of the reference eye point 3, and by constructing the first formula and the second to calculate the average magnification, the actual relationship between the display screen and the imaging device can be more accurately reflected.

[0067] Further, in one embodiment, referring toFigure 2 As shown, both the first display screen 11 and the second display screen 12 are installed on the A-pillar of the vehicle. Before measuring the vertical and horizontal installation angles of the first display screen 11 and the second display screen 12 with the reference eye point 3 as the origin, it includes: determining the position of the reference eye point 3 based on the set height as the initial basis; installing the first display screen 11 and the second display screen 12 respectively based on the height of the reference eye point 3. The set height can be based on the average height as the initial basis, and it is assumed that the driver is sitting in the center of the driver's seat. At this time, the position of the driver's eyes is used as the position of the reference eye point 3, and the first display screen 11 and the second display screen 12 are respectively installed on the A-pillar of the vehicle with reference to the height of the driver's eyes, so that both the first display screen 11 and the second display screen 12 can be at the same height as the driver's eyes. In the embodiment of the present application, the left rearview mirror and the right rearview mirror are also installed near the A-pillar of the vehicle and are respectively installed on the left and right sides of the vehicle. At this time, the first camera device 21 and the second camera device 22 can be respectively installed on the left rearview mirror and the right rearview mirror to be responsible for collecting the visual fields on the left and right sides of the vehicle. During operation, the first camera device 21 and the second camera device 22 transmit the collected picture data to the controller. After being processed by the controller, the pictures are transmitted to the first display screen 11 and the second display screen 12 in the cockpit for display. The pictures captured by the first camera device 21 and the second camera device 22, after being optimized by the graphic image processing module, the image quality finally presented on the high-definition liquid crystal screen is much higher than that of the traditional optical rearview mirror. Such an improvement in clarity not only allows the driver to observe the situation behind more clearly, but also can reduce the driver's visual fatigue to a certain extent. Moreover, in the night or in a relatively dark environment, the visual field of the traditional optical rearview mirror is greatly limited, while the rearview mirror visual field anti-interference mechanism in this embodiment can optimize the visual imaging effect, give the vehicle contour and suppress the high light, so that the driver can understand the road conditions behind more clearly. Such a design undoubtedly further enhances the safety of night driving.

[0068] Preferably, the first display screen 11 and the second display screen 12 configured with the first camera device 21 and the second camera device 22 and the Internet of Things card act as intelligent streaming media devices. By using the first camera device 21 and the second camera device 22 of the vehicle to sense the road condition information, it realizes AR (Augmented Reality) real-time road navigation, real-time storage / retrospective viewing of driving information in the cloud, real-time positioning of the vehicle position information, and real-time obtaining of information during the driving process, etc. These functions not only ensure the safety of the driving process, but also realize the intelligent scene interaction in the vehicle, improving the driving experience and safety.

[0069] In this embodiment, by installing the first display screen 11 and the second display screen 12 at a position approximately at the same height as the driver's eyes, the first display screen 11 and the second display screen 12 are both at the same horizontal line position as the driver's eyes, so that the driver can approach a forward view of the screen in the vertical direction as much as possible, reducing the ambient light interference in the vertical direction. In addition, in the horizontal direction, the horizontal azimuth angle of the first display screen 11 will be adjusted so that when viewed from the driver's position, the screen can be viewed as vertically as possible to reduce the interference of ambient light. The same applies to the second display screen 12. In this way, it can be ensured that the driver can approach a forward view of the display screen in both the vertical and horizontal directions, minimizing the ambient light interference. This solves the problem in the related art that the angle difference between the driver's eyes and the first display screen 11 and the second display screen 12 is too large, making it vulnerable to external light interference.

[0070] Further, in one embodiment, after calculating the horizontal and vertical average magnification ratios of the physical object captured by the first imaging device 21 and displayed on the first display screen 11 and the horizontal and vertical average magnification ratios of the physical object captured by the second imaging device 22 and displayed on the second display screen 12 from the perspective of the reference eye point 3, it includes: calculating the ratio of the horizontal average magnification ratio of the physical object captured by the first imaging device 21 and displayed on the first display screen 11 to the vertical average magnification ratio of the physical object captured by the first imaging device 21 and displayed on the first display screen 11 from the perspective of the reference eye point 3, denoted as the first ratio; calculating the ratio of the horizontal average magnification ratio of the physical object captured by the second imaging device 22 and displayed on the second display screen 12 to the vertical average magnification ratio of the physical object captured by the second imaging device 22 and displayed on the second display screen 12 from the perspective of the reference eye point 3, denoted as the second ratio; respectively determining whether both the first ratio and the second ratio are within the design range. That is, after respectively determining that the horizontal average magnification ratio of the first display screen 11, the horizontal average magnification ratio of the second display screen 12, the vertical average magnification ratio of the first display screen 11, and the vertical average magnification ratio of the second display screen 12 all meet the requirements, the ratio of the horizontal average magnification ratio to the vertical average magnification ratio of the first display screen 11 and the ratio of the horizontal average magnification ratio to the vertical average magnification ratio of the second display screen 12 can be calculated respectively to confirm the aspect ratio of the magnification of the first display screen 11 and the second display screen 12. In the embodiment of the present application, the acceptable ranges of the first ratio and the second ratio can both be set as:

[0071] In this embodiment, through the aspect ratio of the magnification factors of the first display screen 11 and the second display screen 12, the average magnification factors of the first display screen 11 and the second display screen 12 in the horizontal direction or the vertical direction can be designed more precisely, so that the driver can have a better viewing experience when observing the first display screen 11 and the second display screen 12 during driving.

[0072] Furthermore, when the driver observes the first display screen 11 and the second display screen 12, a small floating difference in the viewing angle is allowed. The size of the angular floating difference is determined by the difference in the picture effects seen by the driver. Within the angular floating range, the picture content parameters of the first display screen 11 and the second display screen 12 seen by the driver should be close. Moreover, the left and right display screens are respectively set with different sizes. The first display screen 11 is installed near the driver's seat and is closer to the driver, so the display screen size can be set smaller. The second display screen 12 is installed near the co-driver's seat and is farther from the driver's position than the first display screen 11, so the size of the second display screen 12 is set larger. According to the ratio of the distance between the driver and the first display screen 11 to the distance between the driver and the second display screen 12, the size ratio of the first display screen 11 and the second display screen 12 is respectively confirmed to ensure that the picture ratios of the first side display screen and the second side display screen seen by the driver are close, thereby enhancing the visual effect.

[0073] Furthermore, in one embodiment, after determining whether both the average magnification factor in the horizontal direction and the average magnification factor in the vertical direction calculated meet the requirements, if so, it is qualified; otherwise, if it is unqualified, it includes: adjusting the deflection angles and / or the screen sizes of the first display screen 11 and / or the second display screen 12; calculating the average magnification factors in the horizontal and vertical directions of the physical object captured by the first imaging device 21 and displayed on the first display screen 11 and the average magnification factors in the horizontal and vertical directions of the physical object captured by the second imaging device 22 and displayed on the second display screen 12 from the perspective of the reference eye point 3 after adjustment, until it is qualified. That is, when any one of the calculated average magnification factors in the horizontal direction and the average magnification factor in the vertical direction does not meet the requirements, either one or both of the first display screen 11 and the second display screen 12 can be adjusted. When adjusting, the deflection angles of the first display screen 11 and the second display screen 12 can be adjusted, or the screen sizes of the first display screen 11 and the second display screen 12 can be adjusted. After the adjustment is completed, the respective data after adjustment are obtained or measured again, and the above calculation process is repeated. If it is still unqualified, the adjustment and calculation processes are repeated until the calculation result meets the requirements and is finally qualified.

[0074] In this embodiment, by adjusting the first display screen 11 and the second display screen 12 respectively, when any calculation result does not meet the requirements, the deflection angle or the screen size of the display screen that needs to be adjusted can be adjusted separately.

[0075] Furthermore, by providing the first imaging device 21 and the first display screen 11 that cooperates with the first imaging device 21, and the second imaging device 22 and the second display screen 12 that cooperates with the second imaging device 22, the vehicle can reduce the impact of bad weather such as rain and snow on the field of vision through hardware and software during driving, minimize the interference with the driver's field of vision as much as possible, and significantly improve the driving safety at night or under bad weather conditions. Compared with traditional optical rearview mirrors, the electronic rearview mirrors in the embodiments of the present application have obvious advantages, especially in terms of the field of vision and environmental impact. The electronic rearview mirrors provide a wider field of vision through different sensors and cameras, ensuring the safety of vehicle driving and other road participants.

[0076] In addition, since the external device only has the sensor components of the first imaging device 21 and the second imaging device 22, its volume is much smaller than that of the traditional optical rearview mirror, reaching one-third or even smaller of the traditional rearview mirror. This design not only conforms to the principle of aerodynamics, reduces wind resistance, but also can effectively reduce high-speed wind noise, providing a more comfortable driving environment for the driver.

[0077] Preferably, the cover plate surfaces of the first display screen 11 and the second display screen 12 are provided with AR (anti-reflection), AG (anti-glare), and AF (Anti-fingerprint) coatings. The AR film can improve the transmittance of the display screen and reduce the reflectivity. The AG film can reduce the interference of ambient light and reduce screen reflection, thereby increasing the viewing angle of the picture. The AF film can minimize the surface tension of the glass, reduce the contact area between dust and the glass surface, making it have strong hydrophobic, anti-oil, and anti-fingerprint capabilities, and keeping the video glass panel clean and bright for a long time.
