AD Station W100 is a research and development platform for autonomous vehicle acquisition, calculation, and hardware in the loop simulation testing of HIL. It can be paired with 16 channel in car camera GMSL acquisition card A16, 8 channel in car video injection card S2, and 4 channel in car video injection card S1
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
