Abstract

The invention belongs to the technical field of video recording, and relates to a four-camera video recording method based on a TDA4 development board. The method comprises the following steps: a J721EXCPXEVM development board is connected with a video fusion board EVM577PFUSION-V1-0; an LVDS (Low Voltage Differential signal) interface of the video fusion board is connected with cameras of four paths of AR0143 UB933 serializers; after driving configuration is completed, the development board is lightened; capturing four paths of camera image data, wherein the image format is UYVY; a J721EXCPXEVM development board and a J721EXSOMXEVM core board are adopted, and the J721EXCPXEVM development board is used as a core board; the image data in the UYVY format is used, and the image format is changed into the NV12 format through an image data conversion module; and converting the image data in the NV12 format into RGB image data, setting a code rate and a coding format, and finally outputting the RGB image data to a local avi video file. In the prior art, a general around-view camera is only used for displaying the surrounding condition of the vehicle and does not have a video recording and storing local function, and the video of each camera can be recorded in the vehicle at any time and stored as a local file in an avi format.

Description

technical field [0001] The invention belongs to the technical field of video recording, and relates to a video recording method for 4-channel cameras based on a TDA4 development board. Background technique [0002] The car surround view system is composed of multiple wide-angle cameras installed on the car body, each camera covers a certain area, and through the images displayed by the 4 cameras, you can intuitively see the situation around the vehicle, preventing the driver from Scuffing occurs while driving or reversing. The present invention is based on the TDA4 development board, and is connected with 4 cameras at the front, rear, left, and right sides. Generally, the surround view camera is only used to display the surrounding conditions of the vehicle, and there is no function of recording video and saving it locally. The present invention can record the video of each camera in the car at any time and save it in avi format local files. Contents of the invention [...
