Description

Technical Field

[0001] The present application relates to the technical field of automotive electronic rearview mirrors, and in particular to a method, device, equipment and storage medium for displaying a rear view of a vehicle. Background Art

[0002] In recent years, electronic rearview mirror technology has developed rapidly. It obtains image information from the rear of the vehicle through cameras arranged at the rear and on the left and right sides of the vehicle, and projects it onto the electronic display screen inside the vehicle to replace the function of traditional optical rearview mirrors. Currently, electronic interior rearview mirrors have been widely used in China. At the same time, some commercial vehicles in overseas markets are also equipped with electronic exterior rearview mirrors.

[0003] At the same time, when using electronic rearview mirrors, multiple electronic rearview mirrors are integrated into a large central electronic rearview mirror, and the image information obtained by multiple cameras is spliced ​​to obtain a large picture, thereby solving the problem in related technologies that multiple screens are located on the left, above and right side of the driver's head, resulting in the rear picture being divided and the driver cannot observe the overall situation behind the car at the same time.

[0004] However, in actual use, the above-mentioned related technologies often need to intercept the image information obtained by each camera according to the changes in vehicle status, such as changes in vehicle speed, gear position or steering wheel steering angle, and further stitch the intercepted images so that the images presented on the electronic rearview mirror can have a change in viewing angle. In this process, due to the changes in each image, different stitching logics will be replaced during stitching to process the data of the image information. Therefore, the electronic rearview mirror system needs to develop multiple sets of algorithm logics according to demand, which not only places higher performance requirements on the controller, but also greatly increases the difficulty, cycle and cost of the development of the entire system.

[0050] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of this application. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0051] At present, in the process of using electronic rearview mirrors, it is often necessary to intercept the image information obtained by each camera according to the changes in the vehicle state, such as changes in vehicle speed, gear position or steering wheel steering angle, and further splice the intercepted images so that the images presented on the electronic rearview mirror can produce changes in viewing angle. In this process, since each image has changed, different splicing logics will be replaced during splicing to process the data of the image information. Therefore, the electronic rearview mirror system needs to develop multiple sets of algorithm logics according to demand, which not only places higher performance requirements on the controller, but also greatly increases the difficulty, cycle and cost of the development of the entire system. In order to solve the above problems, the embodiments of the present application provide a method, device, equipment and storage medium for displaying the rear image of a vehicle.

[0052] The embodiments of the present application provide a method, device, equipment and storage medium for displaying the rear image of a vehicle. The inventive concept is to obtain a combined image under a fixed viewing angle by splicing multiple area images captured by a camera module through a preset splicing logic, and then select the part corresponding to the vehicle status signal from the combined image according to the vehicle status signal as the display image, thereby realizing that only one image splicing logic needs to be executed, greatly reducing the performance requirements for related equipment and the difficulty of developing the entire system.

[0053] In a first aspect, an embodiment of the present invention provides a vehicle rear screen display device, which may be a device having a data processing function, such as a personal computer (PC), a notebook computer, or a server.

[0054] Reference Figure 1 , Figure 1It is a hardware structure diagram of the vehicle rear screen display device involved in the embodiment of the present invention. In the embodiment of the present invention, the vehicle rear screen display device may include a processor 1001 (such as a central processing unit, CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components; the user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard); the network interface 1004 may optionally include a standard wired interface, a wireless interface (such as wireless fidelity WIreless-FIdelity, WI-FI interface); the memory 1005 may be a high-speed random access memory (random access memory, RAM), or a stable memory (non-volatile memory), such as a disk storage, and the memory 1005 may optionally be a storage device independent of the aforementioned processor 1001. Those skilled in the art will understand that Figure 1 The hardware structure shown in the figure does not constitute a limitation of the present invention, and may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0055] Continue to refer to Figure 1 , Figure 1 The memory 1005 as a computer storage medium may include an operating system, a network communication module, a user interface module, and a vehicle rear screen display program. The processor 1001 may call the vehicle rear screen display program stored in the memory 1005 and execute the vehicle rear screen display method provided in the embodiment of the present invention.

[0056] In a second aspect, an embodiment of the present invention provides a method for displaying a rear image of a vehicle.

[0057] Reference Figure 2 , a vehicle rear screen display method, comprising:

[0058] S100, obtaining regional images of multiple areas behind the vehicle;

[0059] S200, combining different regional images according to a preset splicing logic to obtain a combined image;

[0060] S300, obtaining a vehicle status signal, and selecting at least a portion of the combined screen as a display screen according to the vehicle status signal;

[0061] S400: Adaptively adjust the display image and display it on a display interface.

[0062] In some possible implementations, when acquiring regional images of multiple areas of the vehicle in step S100, the camera devices used to acquire regional image images, such as cameras, all acquire images under their respective maximum viewing angles, so that the images acquired in step S100 and the combined images spliced ​​in step S200 are the maximum range images that can be acquired, and when selecting at least part of the images from the combined images as the display images in step 300, the corresponding images can always be acquired according to the vehicle status signal, avoiding the omission of the images of the relevant areas. At the same time, in other possible implementations, the viewing angle of the camera device corresponding to the images acquired in step S100 can also be adjusted as needed.

[0063] At the same time, in different implementations, the parts of the combined picture corresponding to two different vehicle status signals may be the same or different, and can be adjusted according to the actual field of vision when driving the vehicle.

[0064] In step S400, the adaptive adjustment of the display screen is specifically, in some embodiments, to display the selected display screen in full screen mode on the display interface all the time, so as to ensure that when a part of the combined screen is selected as the display screen, the part of the screen is enlarged to facilitate the observation of the occupants when needed. In other embodiments, other adaptive adjustments can be made to the obtained display screen according to display needs, and the embodiments of the present application are only used as examples and are not limited thereto.

[0065] Through the above scheme, the acquired images of multiple areas behind the vehicle are spliced ​​through the preset splicing logic to obtain a combined image under a fixed viewing angle, and then the part corresponding to the vehicle status signal is selected from the combined image according to the vehicle status signal as the display image, thereby realizing that only one image splicing logic needs to be executed, greatly reducing the performance requirements for related equipment and the difficulty of developing the entire system.

[0066] Reference Figure 3 In some possible implementations, the step S300 of acquiring a vehicle status signal and selecting at least a portion of the combined screen as a display screen according to the vehicle status signal comprises the following steps:

[0067] S310, acquiring a vehicle status signal, and determining a vehicle status according to the vehicle status signal;

[0068] S320: Select a display screen on the combined screen according to the vehicle state and a screen selection range corresponding to the preset vehicle state.

[0069] With such a configuration, the implementation method of the present application can select different screen selection ranges according to different vehicle status signals, and finally select a display screen on the combined screen using the selected screen selection range. Compared with the related art, in which different splicing logics are replaced after the regional screen used to splice the combined screen changes to obtain the final display screen, the present application can obtain the display screen by directly determining a screen selection range on the combined screen whose viewing angle range has not changed according to the vehicle status signal, which will effectively reduce the difficulty of designing and executing the system program, and is also more beneficial to cost control.

[0070] Specifically, in different embodiments of the above implementation, the screen selection range corresponding to the vehicle state can be preset as follows: different vehicle states correspond to screen selection ranges of different combination screens, or multiple different vehicle states can correspond to the same screen selection range of the combination screen. In this embodiment, different specific vehicle states correspond to three screen selection ranges in total. Figure 6 , wherein the three screen selection ranges correspond to the first range screen, the second range screen and the third range screen of the combined screen respectively, the first range screen is consistent with the combined screen, the second range screen is a partial screen of the first range screen, and the third range screen is a partial screen of the second range screen. Meanwhile, in other embodiments, different vehicle states may correspond to other numbers of screen selection ranges, and the combined screen parts corresponding to different screen selection ranges may also overlap or be completely different, which is only taken as an example in this embodiment and is not limited thereto.

[0071] Reference Figure 4 In some other possible implementations, the step S300 of acquiring a vehicle status signal and selecting at least a portion of the combined screen as a display screen according to the vehicle status signal comprises the following steps:

[0072] S310, acquiring a vehicle status signal, and determining a vehicle status according to the vehicle status signal;

[0073] S320, obtaining a display screen set including multiple screens with different ranges according to the combination screen and the preset selection ranges of multiple combination screens;

[0074] S330: Select a display screen from the display screen set according to the vehicle state and the preset correspondence between multiple vehicle states and multiple different range screens.

[0075] With this arrangement, the process of forming a display screen set according to the selection ranges of multiple preset combination screens by the combination screen has nothing to do with the vehicle state. After the vehicle state is determined, one of the formed range screens will be directly selected from the display screen set as the display screen. Furthermore, after the vehicle state changes, there is no need to intercept the combination screen again using a different selection range, but the range screen in the display screen set can be directly used, which has a faster response speed, and the selection logic of the multiple range screens in the display screen set does not need to change. It is only necessary to simply select the multiple range screens from the combination screen according to the logic. While ensuring that the overall control logic is easy to execute, an existing range screen in the display screen set can be quickly replaced as the display screen after the vehicle state changes. This is more real-time and conducive to actual driving use.

[0076] Further, in step S320, according to the combined picture and the preset selection range of multiple combined pictures, a display picture set including multiple different range pictures is obtained, and the display picture set includes at least a first range picture and a second range picture, the first range picture is consistent with the combined picture, and the second picture is a partial picture of the first range picture, see Figure 6 .

[0077] With such an arrangement, when the display screen is displayed on the display interface, the combined screen can be magnified in the first order or the second order as needed according to the vehicle state, or the combined screen can be directly displayed without magnification. In the case of the vehicle state of directly displaying the combined screen, there is no need to intercept the combined screen, so as to simplify the execution logic. In addition, in other embodiments, the number of different range screens in the display screen set can be different, and the combined screen parts corresponding to the different range screens can overlap or be completely different. This is only used as an example in this embodiment and is not limited.

[0078] Furthermore, the step S330, selecting a display screen from the display screen set according to the vehicle state and the preset correspondence between the multiple vehicle states and the multiple different range screens, comprises the following steps:

[0079] S331, if the vehicle is in a forward gear, the turn signal lamp is not turned on, and the vehicle speed is lower than a preset first vehicle speed, selecting a first range picture from the display picture set as a display picture;

[0080] S332, if the vehicle is in a forward gear, the turn signal lamp is not turned on, and the vehicle speed is greater than a preset first vehicle speed, selecting a second range picture from the display picture set as the display picture;

[0081] S333: if the turn signal is on, select a first range picture from the display picture set as the display picture;

[0082] S334: If the vehicle is not in the forward gear, select a first range picture from the display picture set as the display picture.

[0083] Further, refer to Figure 6 , the display picture set also includes a third range picture, and the third range picture is a partial picture of the second range picture;

[0084] The step S330, selecting a display picture from the display picture set according to the vehicle state and the preset correspondence between the multiple vehicle states and the multiple different range pictures, further includes the following steps:

[0085] S335. If the vehicle is in a forward gear, the turn signal is not turned on, and the vehicle speed is greater than a preset second vehicle speed, a third range image is selected from the display image set as the display image; wherein the second vehicle speed is greater than the first vehicle speed.

[0086] Set it up like this, refer to Figure 6 , when the vehicle speed is less than the first speed, that is, the vehicle speed is in a low speed state, the display interface can display the picture at the maximum viewing angle; when the vehicle speed is greater than the first speed and less than the second speed, the part of the first range picture can be automatically enlarged; when the vehicle speed is greater than the second speed, that is, the vehicle speed is in a high speed state, the display interface can be further enlarged on the basis of the second range picture to obtain a third range picture with the smallest viewing angle but clearer picture-related details; and when the vehicle turns on the turn signal or is in reverse gear, the first range picture corresponding to the maximum viewing angle is displayed, so that the driver can observe the road conditions behind.

[0087] In some possible implementations, in order to facilitate occupants in the vehicle to quickly understand the displayed screen information, in the process of splicing the regional screens of each area to form a combined screen in step S200, a virtual vehicle body image is simultaneously added to the display screen, and the regional screens are correspondingly spliced ​​on each side of the virtual vehicle body image, ultimately forming a combined screen with a virtual vehicle body image.

[0088] Furthermore, when the display screen is selected by using the combination screen changer in the future, it is also possible to display the partial combination screen with the virtual vehicle body image as the display screen, so that people in the car can understand it more quickly when observing the display screen, which is convenient for grasping the specific situation of the current rear of the vehicle and is beneficial to actual driving.

[0089] Reference Figure 5In some possible implementations, after the step S300 of acquiring the vehicle status signal and selecting at least part of the combined screen as the display screen according to the vehicle status signal, further includes:

[0090] S340, in response to a picture selection signal, selecting a display picture from the display picture set according to a preset correspondence relationship between multiple picture selection signals and multiple pictures of different ranges; the picture selection signal is manually input.

[0091] Among them, the picture selection signal can be realized by a related trigger module arranged in the car, that is, the user can select the corresponding picture selection signal on the related trigger module according to the needs, and then through the correspondence between the picture selection signal and the pictures of different ranges, the display picture can be adjusted according to the user's own choice when needed, which has strong practical significance.

[0092] In some possible implementations, after the vehicle is powered on, the vehicle will first display the perspective image when the display interface was turned off when the vehicle was powered off last time.

[0093] Through the above scheme, since the driver often actively parks the vehicle when the power is cut off, and the display screen displayed on the display interface during the parking process is consistent with the display screen when the vehicle starts to be driven, therefore, setting the vehicle to directly use the display screen when the power is cut off last time when the vehicle is powered on, this process can be more convenient and quick, and the control logic can be simplified to a certain extent, which is conducive to practical use.

[0094] In a third aspect, the present application provides a vehicle rear screen display device.

[0095] Reference Figure 7 , a vehicle rear screen display device, comprising:

[0096] A camera module, which is used to obtain images of respective areas of a plurality of areas behind the vehicle;

[0097] A processing module, which is used to combine different regional images according to a preset splicing logic to obtain a combined image, and select at least part of the combined image as a display image according to a vehicle state signal;

[0098] The display module is used to display the obtained display picture.

[0099] In a fourth aspect, the present application provides a storage medium.

[0100] A storage medium non-temporarily stores computer-readable instructions, which, when executed by a computer, can implement the vehicle rear screen display method as described above.

[0101] The beneficial effects of a vehicle rear screen display method, device, equipment and storage medium provided in the present application are: the acquired multiple area screens of the rear of the vehicle are spliced ​​together through a preset splicing logic to obtain a combined screen under a fixed viewing angle, and then the part corresponding to the vehicle status signal is selected from the combined screen according to the vehicle status signal as the display screen, thereby realizing that only one screen splicing logic needs to be executed, greatly reducing the performance requirements for related equipment and the difficulty of developing the entire system. At the same time, in some embodiments, the process of forming a display screen set by combining screens according to the selection ranges of multiple preset combination screens has nothing to do with the vehicle state. After the vehicle state is determined, one of the formed range screens will be directly selected from the display screen set as the display screen. Furthermore, after the vehicle state changes, there is no need to intercept the combined screen again using a different selection range. The range screen in the display screen set can be directly used, which has a faster response speed, and the selection logic of the multiple range screens in the display screen set does not need to change. It is only necessary to simply select the multiple range screens from the combined screen according to the logic. While ensuring that the overall control logic is easy to execute, when the vehicle state changes, a range screen already in the display screen set can be quickly replaced as the display screen, which is more real-time and conducive to actual driving use.
