Aiming at the shortcomings of the current ARM and DSP-based embedded image processing system, the front-end acquisition speed is slow and the image processing algorithm is not easy to accelerate, a full HD (resolution 1920×1080) real-time video acquisition and image processing based on the HDMI interface is designed system. A 5 million pixel CMOS camera is used as the front-end data source. The main chip uses an ARM+FPGA heterogeneous architecture, which has both the parallel processing capability of the FPGA and the task scheduling function of the ARM processor. Based on the AXI protocol, a custom data storage and transmission IP core is designed to maximize processing speed and bandwidth. Use the HLS tool to quickly package the image preprocessing algorithm to generate an IP core, implement hardware acceleration of the image algorithm in FPGA, and complete the design of the image processing system platform prototype. Compared with the traditional PC and camera combined machine vision platform, the system takes an average of less than 10ms to run, and the real-time detection effect is satisfactory, effectively solving the contradiction between low power consumption and high data bandwidth and processing speed. Provides good support for back-end result analysis and edge acceleration.
