Design of PCIe-Based Color Recognition and Tracking System

The tracking of target location plays an important role in animal behavior experiments. In order to meet the demand for high-speed transmission and fast processing of images in experiments, this paper designs an image transmission and processing system based on PCIe high-speed communication interface, which can track objects of specific colors within the screen in real time. By using the upper computer software designed based on the QT framework, the system is able to receive images containing calibration information in real time and make them available to researchers. The system's control and processing core uses Xilinx's Artix-7 series FPGAs, the Riffa framework to drive the PCIe high-speed communication interface data transceiver, and DDR3 SDRAM as the core of the high-speed memory module. The image acquisition device uses OV7670 CMOS, and the whole system realizes the complete process from image acquisition, processing, transmission to display.
