摘要
设计了基于PXA270Xscale处理器和多片TMS320DM642DSP处理器的并行智能视频监控系统,详细介绍了其体系结构的特点,关键模块的硬件组成及工作原理,并通过在该系统上实现运动目标的实时跟踪算法验证了系统的设计性能。验证结果表明,该监控系统具有处理速度快、接口丰富、成本低廉、可重构的特点,适合应用于视觉导航、安全监控等要求高速视频图像处理的场合。
Based on PXA270 Xscale processor and TMS320DM642 Multi-DSPs processor, a new parallel intelligent video surveillance system is designed. Firstly, the architecture, hardware configuration, and principle of the system are introduced in detail. Subsequently, in order to validate the system＇s performance, the algorithm for motion detection and objects tracking is transplanted to DSPs on realworld circumstance. Experimental result shows that the system proposed has the characteristics of high operation speed, sufficient resource, low cost, etc., which can used to the fields require high-speed digital image processing such as vision navigation and safety surveillance.
