USB3.0-based analog camera detection board

The invention discloses a USB3.0-based analog camera detection board, which comprises a video decoding circuit, a level conversion circuit, an FPGA receiving circuit, a USB3.0 control circuit and a PC in serial connection sequentially, wherein the video decoding circuit receives a PAL/NTSC/SECAM analog signal and outputs a video signal ITU-R BT.656 to the level conversion circuit, and the signal is only received by the FPGA receiving circuit through level conversion of the level conversion circuit; the video decoding circuit adopts a TVP5150AM1 chip, the analog signal is converted into a parallel interface data signal, and the FPGA receiving circuit transmits the signal to the USB3.0 control circuit at a 100M signal rate; and the USB3.0 control circuit transmits the signal to the PC at a 5G signal rate. Analysis transmission on an image with a higher resolution and a higher frame rate can be met, and requirements of compatible analysis on multiple resolutions can also be met.
