Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted displays, and in particular to the field of intelligent driving assistance, and specifically refers to an intelligent vision compensation system, method, device, processor and computer-readable storage medium thereof for avoiding occlusion of the A-pillar of an automobile. Background Art

[0002] When driving a car, the driver's vision is often blocked by the A-pillar and the left front pillar, which not only affects driving comfort but also increases the risk of driving safety. Traditional solutions usually rely on physical design changes, such as adjusting the shape or angle of the A-pillar, or increasing the use of side mirrors. However, these methods have obvious limitations.

[0003] The disadvantage of physical design adjustments is that they often require major changes to the overall structure of the car, which not only increases manufacturing costs but may also affect the aerodynamic performance and aesthetics of the vehicle. In addition, even if adjustments are made, the problem of line of sight obstruction cannot be completely eliminated because the structure of the A-pillar and the left front pillar is critical to the safety of the vehicle and cannot be completely removed.

[0004] While the use of side-view mirrors can reduce visual obstruction to a certain extent, they also have their own disadvantages. Side-view mirrors may increase wind resistance, affecting fuel efficiency, and in inclement weather conditions, side-view mirrors may be obscured by rain or fog, further reducing their effectiveness.

[0005] Additionally, some vehicles attempt to provide views of blind spots by adding additional cameras, but these systems often lack integration and intelligence. They may require the driver to frequently check multiple screens, distracting the driver rather than providing a seamless visual compensation experience.

[0006] In summary, traditional solutions have obvious shortcomings in reducing the A-pillar and left front pillar vision obstruction. They either fail to provide sufficient vision, add additional complexity and cost, or affect the performance and safety of the vehicle. Therefore, it is urgent to develop an intelligent vision compensation system that can be seamlessly integrated into the car design to provide a clear, real-time blind spot view without adding additional wind resistance or distracting the driver's attention. Summary of the invention

[0038] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.

[0039] Before describing in detail embodiments according to the present invention, it should be noted that, hereinafter, the terms "comprises", "includes" or any other variations are intended to cover non-exclusive inclusion, whereby a process, method, article or apparatus comprising a series of elements includes not only these elements, but also other elements not explicitly listed or inherent to such process, method, article or apparatus.

[0040] The intelligent visual compensation system for avoiding occlusion of the A-pillar of an automobile comprises:

[0041] The camera data acquisition module is used to capture the road condition information of the A-pillar shielded area in real time by installing one or more high-definition wide-angle cameras on the outside of the A-pillar of the car;

[0042] An information collection display module is connected to the camera data collection module and installed inside the A-pillar to display the A-pillar blind spot image captured by the camera data collection module in real time;

[0043] An image processing and transmission module, connected to the camera data acquisition module and the acquisition information display module, for transmitting the image captured by the camera data acquisition module to the acquisition information display module through a high-speed signal transmission system inside the car; and

[0044] The intelligent switching and calibration module is used to calibrate the relative position of the driver's eyes and the display screen by adjusting the angle and depth of the camera through the internal visual compensation system according to the driver's height and seat height usage habits.

[0045] As a preferred embodiment of the present invention, the viewing angle of the high-definition wide-angle camera is 170°, the camera is installed 5 cm away from the outer edge of the A-pillar, and the height is 70 cm from the vehicle chassis.

[0046] As a preferred embodiment of the present invention, the display area of ​​the acquisition information display module adopts a transparent OLED screen with a resolution of 1920×1080, a refresh rate of 60 Hz, and a brightness of 500 nits.

[0047] As a preferred embodiment of the present invention, the image processing and transmission module performs denoising and contrast enhancement on the acquired image during data transmission, wherein a median filtering algorithm is used for denoising, and the filter window size is 3×3; a linear stretching algorithm is used for contrast enhancement, and the stretching coefficient is 1.2.

[0048] As a preferred embodiment of the present invention, when the driver's height is between 150 cm and 190 cm, the camera angle adjustment range is 20° up and down, 15° left and right, and the depth adjustment range is 10 cm front and back.

[0049] The intelligent visual compensation method for avoiding automobile A-pillar occlusion is implemented by using the above-mentioned system, wherein the method comprises the following steps:

[0050] (1) After the vehicle is started, the system automatically turns on and the camera begins to capture road conditions in the area blocked by the A-pillar;

[0051] (2) The camera data acquisition module transmits the captured images to the image processing and transmission module in real time for preprocessing;

[0052] (3) The pre-processed image is transmitted to the acquisition information display module for real-time display;

[0053] (4) The system continuously monitors the driver’s height and seat position parameter changes;

[0054] (5) When there are parameter changes, the system automatically adjusts the angle and depth of the camera to ensure that the displayed content accurately compensates for the A-pillar obstruction so that the driver can view it in real time.

[0055] In practical application, the implementation method of this technical solution is as follows:

[0056] Camera setup: Install one or more high-definition cameras near the left front pillar of the car (such as the outside of the A-pillar). These cameras include but are not limited to wide-angle or ultra-wide field of view, which can capture the road condition information of the area blocked by the A-pillar. The best solution for the camera is to just make up for the sight of the driver's position blocked by the left front pillar, and cooperate with the display screen installed on the inner side of the left front pillar to display the blocked picture;

[0057] Display device integration: A display device is installed on the inner side of the left front pillar to display the A-pillar blind spot image captured by the camera in real time. This display area can be designed to blend with the surrounding environment. The best solution is to just make up for the image blocked by the left front pillar, as if the left front pillar is a transparent object;

[0058] Image processing and transmission: The image captured by the camera is transmitted to the display device through the signal transmission system inside the car. During the transmission process, the image may be pre-processed, such as denoising and contrast enhancement, to improve the image clarity and readability;

[0059] Intelligent switching and calibration: The visual compensation system of the left front pillar can be calibrated according to the driver's height and seat height usage habits, that is, the relative position of the driver's eyes and the display screen, by adjusting the angle and depth of the camera to ensure that the image captured by the camera and the display content on the display device just compensate for the obstruction of the left front pillar.

[0060] A specific embodiment is given below to better illustrate the implementation scenario of this technical solution:

[0061] Step 1: Choose a common family car as the test vehicle, and install two high-definition wide-angle cameras near the left front pillar of the vehicle (outside the A-pillar). The camera viewing angle is 170°, and the installation position is 5 cm away from the outer edge of the A-pillar and 70 cm above the vehicle chassis.

[0062] Step 2: Install a transparent OLED display device with a length of 20 cm and a width of 15 cm on the inner side of the left front pillar, with a resolution of 1920×1080, a refresh rate of 60 Hz, and a brightness of 500 nits.

[0063] Step 3: The vehicle starts, the system automatically turns on, and the camera starts to capture road conditions. At this time, a driver with a height of 170 cm sits in the driver's seat, with a moderate seat height and normal front and rear position.

[0064] Step 4: The captured image is transmitted to the image processing module at a transmission rate of 5 Gbps for median filtering denoising (filter window size is 3×3) and linear stretching contrast enhancement (stretching factor is 1.2).

[0065] Step 5: The processed image is transmitted to the display device for real-time display, and the driver can clearly see the road conditions in the A-pillar blind spot.

[0066] Step 6: When the driver adjusts the seat height to raise it by 10 cm, the system detects this change and automatically adjusts the camera angle upward by 10° and forward by 5 cm to ensure that the displayed content still accurately compensates for the A-pillar blocking the image.

[0067] Step 7: Test the stability and reliability of the system in different driving scenarios, such as urban roads, highways, and curves.

[0068] Step 8: Record the system performance data during the test, including image clarity, response speed, calibration accuracy, etc., and optimize and improve the system.
