Video signal processing system and method for automatic driving and ADAS

Abstract

The invention discloses a video signal processing system and method for automatic driving and ADAS, and belongs to the field of automatic driving, the system comprises a signal equalizer, an AHD decoder, an FPGA chip and an RK3588 chip; the signal equalizer receives the SDI video signal and the HDMI video signal and transmits the SDI video signal and the HDMI video signal to the FPGA chip; the AHD decoder receives an AHD video signal and transmits the AHD video signal to the FPGA chip; the FPGA chip receives SDI video signals and HDMI video signals through a high-speed serial transceiver inside the FPGA chip, carries out image processing on the SDI video signals and the HDMI video signals and then transmits the SDI video signals and the HDMI video signals to the RK3588 chip, and the FPGA chip carries out image processing on AHD video signals and then transmits the AHD video signals to the RK3588 chip. The PCIE interface of the FPGA chip is connected with the PCIE interface of the RK3588 chip; and the RK3588 chip performs video decoding, image processing and video coding on the SDI video signal, the HDMI video signal and the AHD video signal after image processing, and then transmits the signals to terminal equipment. According to the method, the problems of existing automatic driving and ADAS solutions in the aspects of computing platform performance, high cost and system integration are effectively solved.
