摘　　要：为了实现全方位监控和智能预警,设计了一套以DM642为核心的全景多目标检测系统。从硬件设计和软件设计两个方面分析了系统和算法的构建、实现和优化。针对该系统复杂的功能和架构,详细分析其工作流程,采用了基于DSP/BIOS的框架搭建,并且设计和采用基于能量累计的背景建模和基于SIFT的图像匹配等关键图像处理算法。并最终通过系统调试验证其设计的可行性。To achieve omni directional monitoring and intelligent warning,a DM642-based panorama multi-target detection system was designed. The construction,achievement and optimization of the system and algorithm are analyzed in the aspects of hardware design and software design. A detail analysis of the system’s operation flaw is done in allusion to complex functions and architecture. The framework is built by DSP/BIOS. The background modeling based on energy accumulation and critical image processing algorithm based on SIFT are applied. Finally,the feasibility was verified by the system debugging.
