针对嵌入式机器视觉系统向独立化、智能化发展的要求,介绍了一种嵌入式视觉系统--智能相机。基于对智能相机体系结构、组成模块和图像采集、传输和处理技术的分析,对国内外的几款智能相机进行比较。综合技术发展现状,提出基于FPGA+DSP模式的硬件平台,并提出智能相机的发展方向。分析结果表明,该系统设计可以实现脱离PC运行,完成图像获取与分析,并作出相应输出。 Abstract: This paper introduced an embedded vision system-intelligent camera ,which was for embedded machine vision systems to an independent and intelligent development requirements. Intelligent camera architecture, component modules and image acquisition, transmission and processing technology were analyzed. After comparing integrated technology development of several intelligent cameras at home and abroad, the paper proposed the hardware platform based on FPGA+DSP models and made clear direction of development of intelligent cameras. On the analysis of the design, the results indicate that the system can run from the PC independently to complete the image acquisition and analysis and give a corresponding output.
