Abstract

In recent years, the rise of driverless technology makes the video transmission bandwidth of vehicle platform larger and larger. With the increase of the number of cameras used in cars, a large number of cameras will inevitably produce a large amount of data, which greatly increases the data bandwidth of the on-board platform. "Bandwidth" has become one of the biggest challenges faced by automobile manufacturers. This paper mainly studies the video acquisition and storage technology of multi-channel camera based on GMSL (Gigabit multimedia serial links), which can well solve the problem of data transmission bandwidth. Firstly, the principle of GMSL technology is studied; Secondly, taking FPGA processor as the core control chip, a multi-channel video acquisition and storage system based on GMSL is designed, the overall design scheme and hardware architecture are given, and the hardware circuit design of the system is completed; Finally, the technical feasibility of the system is verified, and the experimental effect of the system is good.
