摘要
开发了一种基于数字信号处理器(DSP)TMS320DM642的嵌入式高速图像识别系统。该系统实现了对每帧1024×1500像素的黑白图像的高速采集处理,速度最高可达到每秒5帧。硬件主要包括线阵CCD传感器、DSP处理器(TMS320DM642)、处理电路等3个部分。阐述了CCD采集工作原理和TMS320DM642处理器的工作原理,以及DSP处理系统的硬件设计及驱动管理。介绍了图像识别的算法结构及流程图。
A high-speed embedded image processing system based on digital signal processor （DSP） was developed. The system captured and processed black and white images in high speed; and the max speed reaches 5 frames （one frame has 1024 ＊ 1500 pixels） per second. The hardware of the system is mainly composed of three parts： a linear CCD sensor, a piece of DSP （TMS320DM642） and the corresponding processing circuit. The hardware design and drive -management of the image processing system are illustrated and the operating principles of CCD sensor and TMS320DM642 are introduced. The algorithm structure and flow chart are also given.
