S101, matching two camera shooting display components, wherein each camera shooting display component comprises a camera and an in-vehicle electronic display mirror.
Wherein, the collocation display module that makes a video recording, the display module that makes a video recording includes camera and in-vehicle electronic display mirror, and after camera and in-vehicle electronic display mirror have been set up, on-vehicle electron rear-view mirror field of vision scope is also fixed thereupon. The quantity of the camera shooting display component is two, namely the two cameras are respectively a left camera and a right camera, the left camera is arranged at the position of the left rearview mirror of the automobile, and the right camera is arranged at the position of the right rearview mirror of the automobile. The quantity of electronic display mirror also is two in the car, is left display mirror and right display mirror respectively, and left side display mirror matches with left camera, and right side display mirror matches in right camera. The left camera and the right camera each include a sensor (image sensor) and a lens. The pixel resolution of the sensor is larger than the output effective pixel resolution of the electronic display mirror in the vehicle. To make the vehicle-mounted electronic rearview mirror have the function of adjusting the field of view, the actual pixel resolution of the sensor must be greater than the output effective pixel resolution of the sensor (i.e. the output effective pixel resolution of the vehicle-mounted electronic display mirror). In order to make the adjustment range large, the pixel resolution of the sensor is far larger than the output effective pixel resolution of the electronic display mirror in the vehicle.
And S102, transmitting the video signal shot by the camera to an in-vehicle electronic display mirror through a coaxial line.
The electronic display mirror is arranged in the automobile, the number of the electronic display mirrors in the automobile is two, the two electronic display mirrors are respectively a left display mirror and a right display mirror, the left display mirror is connected with the left camera, and the right display mirror is connected with the right camera. The left camera and the right camera are both connected to the in-vehicle electronic display mirror through coaxial lines.
S103, adjusting the visual field range by touching the upper, lower, left and right icons on the interface of the electronic display mirror in the vehicle.
The in-vehicle electronic display mirror interface is provided with up-down, left-right icons (as shown in fig. 2), and when the in-vehicle electronic display mirror is used, a user touches the up-down, left-right icons to adjust the viewing angle of the in-vehicle electronic display mirror.
In an alternative embodiment, referring to fig. 2, the step of adjusting the field of view by touching the up, down, left, and right icons on the electronic display mirror interface in the vehicle includes steps S1031 to S1033.
S1031, the electronic display mirror in the vehicle transmits the coordinate value data of the current icon to the MCU of the vehicle-mounted electronic rearview mirror through the I2C communication interface
S1032, the MCU identifies the icon key corresponding to the coordinate value data of the current picture and sends an instruction to an ISP (image signal processor) through an I2C communication interface.
And S1031, ISP (Internet service provider) configures register moving visual angle of a sensor (image sensor) in the camera through I2C communication interface.
In an alternative embodiment, please refer to fig. 3 and 4, which is a schematic diagram of a method for matching two camera display modules, including steps S1011-S1012.
S1011, calculating the range of upper, lower, left and right pixels of the adjusting picture.
Specifically, the range of pixels up, down, left and right of the adjustment picture is obtained by subtracting the output effective pixel resolution of the electronic display mirror in the vehicle from the actual pixel resolution of the sensor of the camera.
S1012, the actual viewing angle range of the screen movement is calculated.
Specifically, the actual view angle range of the screen movement is calculated from the distortion table of the lens, which includes steps S1012a-S1012 b.
S1012a, the image height of the actual output resolution is calculated from the size of each sensor pixel.
And S1012b, obtaining the angle of view of the horizontal half image height and the vertical half image height by checking a distortion table of the lens, and obtaining the horizontal angle of view and the vertical angle of view of the camera output by using the angle of view x2 of the horizontal half image height and the vertical half image height.
The following is a specific example, sensor model IMX390, with an actual resolution of 2017 x 1217; the resolution of the output effective pixels of the in-vehicle electronic display mirror is 1280 × 720 (shown in fig. 5), the adjustable range of the sensor on the left and the right is 368 pixels, and the adjustable range on the upper and the lower is 248 pixels.
After the upper, lower, left and right pixel ranges of the picture are calculated, a proper lens is matched, and the visual angle range of the actual picture movement can be calculated through a distortion table of the lens. For example, a lens of HJ6040 is used, and the distortion table is shown in fig. 9. IMX390 Each pixel is 3 uM.
First, the view angle of 1280x720 of the camera output is calculated.
The horizontal image height is: 1280x3uM is 3.84mm and the horizontal half-image height is 1.92 mm.
The vertical image height is: 720x3uM is 2.16mm and the vertical half image height is 1.08 mm.
Viewing angle x2 for horizontal and vertical half image height by looking up the distortion table of HJ6040 (as shown in fig. 9) yields horizontal and vertical viewing angles for camera output 1280x 720.
Horizontal viewing angle: 49 degrees; vertical viewing angle: 27.5 °.
By the same principle, the calculated viewing angle ranges for the horizontal movement range of 368 pixels and the vertical movement range of 248 pixels are:
the left-right movement visual angle range is as follows: 14 degrees; the vertical movement viewing angle range is: 9 degrees.
Thus, it can be concluded that the display 1280x720 screen of the electronic rearview mirror is at a horizontal angle of 49 °, a vertical angle of 27.5 °, a left-right adjustable angle of 14 ° and a top-bottom adjustable angle of 9 °, which can completely replace the functions of the traditional physical rearview mirror with adjustable top, bottom, left and right visual fields. For example, fig. 6 is a normal viewing angle, and fig. 7 and 8 are an effect of adjusting a viewing angle up and an effect of adjusting a viewing angle down.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
