For ease of understanding, the purposes of the arrangement of the pin adapter plate 120 and the signal format conversion plate 130 are collectively described herein.
In the process of transmitting the video signal to the projector 140 by the car machine 110, since the video signal is generally large, a high-speed serial interface capable of transmitting the video signal, such as a GMSL interface, is generally selected to ensure the transmission efficiency. However, the existing projector generally only configures a DP Interface or an HDMI (High Definition Multimedia Interface), so a signal format conversion board 130 needs to be added between the car unit 110 and the projector 140 to convert a GMSL signal sent by the car unit 110 into a DP signal or an HDMI signal that can be received by the projector.
Further, since signal-format conversion board 130 and vehicle machine 110 are not generally developed by the same manufacturer in the actual production process of vehicle machine 110 and signal-format conversion board 130, there is generally no uniform pin order standard when packaging pins. The video signal sent by the in-vehicle device 110 generally consists of multiple signals, such as a sound signal and an image signal, each signal needs to be sent to the signal format conversion board 130 according to the pin sequence in the in-vehicle device 110, and in order to ensure that the signal received by the signal format conversion board 130 can satisfy the pin sequence of the signal format conversion board 130, the pin adapter board 120 needs to be added between the in-vehicle device 110 and the signal format conversion board 130, and the pin adapter board 120 can adjust the pin sequence of the signal sent by the in-vehicle device 110 to a signal that can satisfy the pin sequence of the signal format conversion board 130.

Therefore, whether the high definition display film is arranged or not and the specific type of the high definition display film can be determined according to actual requirements, and the method is not limited herein.
Further, the projector 140 and the car unit 110 may have an API (Application Programming Interface) built therein.
The API may be configured to establish a point-to-point communication link between the projector 140 and the car machine 110 when the projection enters a multi-point projection correction mode.
The multipoint correction mode is an optional mode for correcting the projection distortion of the projector 140, and a specific projection distortion correction method will be described in detail in the following embodiments.
According to the technical scheme of the embodiment of the invention, the vehicle machine, the pin adapter plate, the signal format conversion plate and the projector are arranged in the vehicle, so that the high-efficiency stable transmission of the video signal in the process of transmitting the video signal to the projector by the vehicle machine is ensured, and the function of projecting the video signal at the front windshield of the vehicle through the projector arranged in the vehicle is realized.

The real-time correction state information may include: a current correction point and a correction result of the current correction point.
Taking the above-described correction screen having 60 correction points as an example, one coordinate value can be assigned to each point, the position of the current correction point can be obtained from the coordinate values, and the positional relationship between the other correction points and the current correction point can be obtained. The real-time correction state information may include a coordinate value of the current correction point and a correction result indicating whether the current correction point is corrected successfully.

After the projection correction intermediate stage is determined according to the real-time correction state information, the next correction point needing correction can be obtained according to the preset correction point sequence information.
In a specific embodiment, if the current position is in the middle stage of projection correction and the current correction point is successfully corrected, selecting the next correction point for correction according to a preset correction point sequence; and if the current correction point fails to correct, returning to the previous row of backspacing correction points in the same column with the current correction point, and correcting the backspacing correction points again.

The backspacing correction mapping table may include backspacing correction points corresponding to the correction points in the correction picture. In the embodiment of the present invention, the backspacing correction points obtained through the backspacing correction mapping table may be correction points in the upper row in the same column as the correction failure points.
