摘　　要：在研究机器人视觉系统的过程中，研制成功两种基于ＤＳＰ的实时图像处理系统。以４片专用ＤＳＰＩＭＳＡ１１０阵列为核心的系统，达到了８４０ＭＯＰＳ的处理速度，可实时完成各种大小模板的卷积、相关、滤波、边缘检测、增强及阈值化、线性与非线性变换等图像预处理操作。以通用ＤＳＰＴＭＳ３２０Ｃ３０为核心的系统，具有３３．３ＭＦＬＯＰＳ的处理速度，适于高层次图像处理和图像识别。两种系统均以ＰＣ机为宿主机，均配有独立的Ａ／Ｄ、Ｄ／Ａ系统。在设计中采用了创新的循环往复式流水线结构和ＤＭＡ、双口ＲＡＭ、多口共享存储区以及窗口映射等先进技术。系统稳定可靠，具有技术先进性及高的性能价格比。两种系统进一步有机的结合可实现高性能的机器人视觉系统。During the research on robotic vision system,two types of real-time image-processing systems based on DSP have been sucessfully developed. The system which uses special purpose DSP four-chip IMSA110s array as its kernel attains a processing speed of 840MOPS. It can realtimely finish the image pre-processing operation of various sized modules, such as convoluting,correlating, filtering, edge detecting, thresholding, linear and non-linear transforming,etc. The system which uses general purpose DSP TMS320C30 as its kernel can operate at speeds of 33. 3 MFLOPS. It is suitable to do high-level image processing and image recognizating. Either of the two systems uses PC micro-computer as its host computer and has its own independent A/D,D/A systems. Some advanced techniques, such as novel recycling pipe-lined structure, DMA,dualport RAM,multi-port shared memory and window mapping are used in the design. The two systems are of high stability,advanced technique and high ratio of performance to price.The further combination of the two systems can constitute a robotic vision system of high perfomance.
