摘要
以TMS320C6205为处理器,设计一种实时图像识别系统。用SAA7111和FPGA完成无 DSP干预的图像采集与存储,通过DMA实现图像传输与DSP识别的并行执行。系统将触发、采集、存储、识别等功能集成在一块PCI卡上,提高了系统的可靠性和安全性。与基于采集卡和PC机的图像识别系统相比,该系统在保持相同的图像识别准确率的前提下,可以将识别速度提高约28.7%。
A real-time image processing system is designed by using TMS320C6205 as processor. Image sampling and storing are carried out by SAA7111 he FPGA without intervention of digital signal processing. Image transmission and DSP recognition are simultaneously carried out through DMA. The reliability and safety of the system are improved through integration of the functions of triggering, sampling, storing and recognizing in a PCI card. Compared with the image recognition system based on sampling card and PC machine, the system can improve the recognition speed by about 28.7% on the premise of maintaining the same image recognition accuracy.
