The invention provides a monocular camera image multi-channel acquisition device based on an FPGA. The device includes a FPGA, and a MCU module and a DDR storage chip arranged outside the FPGA chip. Amonocular camera interface module, an image frame control module, an image distribution module, an RAW image acquisition module, an RAW image processing module, an image preprocessing module, an acquisition VDMA module, a specific target detection module and a detection VDMA module are arranged in the FPGA. Based on the device, an input monocular camera image is preprocessed, so that the monocular camera image is pre-decomposed into different to-be-detected image data under different frame frequencies, the driving change condition of a vehicle is rapidly detected under the condition that thetotal bandwidth is not changed or limited, and the condition of frame loss or missing detection is avoided. 本发明提供了基于FPGA的单目摄像头图像多通道采集装置，包括FPGA、FPGA片外的MCU模块和DDR存储芯片，在FPGA中设置有单目摄像头接口模块、图像帧控制模块、图像分配模块、RAW图像采集模块、RAW图像处理模块、图像预处理模块、
