Scheme of Automatic Driving Vehicle Diversion Collection and Calculation Platform
After the camera video is collected, it is stored on the disk to provide data support for subsequent algorithm simulation and restoration
The onboard splitter card splits the camera output to the ECU and stores the video data on the disk
