Problems solved by technology
[0003] The MIPI camera is used to obtain video data in the dual-channel video signal. During the entire video data stream collection process, the original dot matrix data is collected from the MIPI camera, converted into color coded data by the video encoding module, and then converted into H264 video stream by the multimedia encoding module. Data needs to go through multiple operation steps, and the system load is heavy, which will affect the normal operation of the entire system
As the requirements for smart rearview mirrors in vehicle safety monitoring and defense continue to increase, the solution for dual-channel video signals has been unable to meet market requirements.

The invention discloses an intelligent rearview mirror multi-camera monitoring system in the field of intelligent rearview mirror monitoring, and an implementation method thereof. The system comprises a main control chip, a USB interface camera and a CVBS interface camera, the CVBS interface camera is connected with the main control chip, and the USB interface camera is connected with the main control chip through a USB multi-port repeater. The method comprises the processes of starting the main control chip, loading a camera drive, inquiring the states of the cameras, obtaining video data, and displaying the video data or providing the video data for a security subsystem. The multichannel high-definition real-time monitoring video solution provided by the invention provides software and hardware support for an omnibearing security monitoring function of intelligent rearview mirrors.
Description
technical field [0001] The invention relates to the technical field of rearview mirror intelligent monitoring, in particular to an intelligent rearview mirror multi-camera monitoring system and its implementation method. Background technique [0002] Existing smart rearview mirror dual-camera video surveillance solutions (for example, the vehicle rearview mirror solution based on Spreadtrum SC7731, which supports dual-channel video signals: 5 million front cameras and 1 million rear view cameras), the reversing images need to monitor the distance In the case of a relatively close position below the rear of the vehicle, the installation angle of the camera is downward, and the video area is limited to a small area under the rear of the vehicle, and the scope of video surveillance is limited. [0003] The MIPI camera is used to obtain video data in the dual-channel video signal. During the entire video data stream collection process, the original dot matrix data is collected f...
