基于Hi3516的矿井运动目标检测系统的设计与实现

摘要

针对煤矿井下专门设计的智能化视频监控系统相对较少的情况，设计与实现了一种基于 Hi3516的矿井运动目标检测系统。该系统以 Hi3516作为核心处理器，通过搭建交叉编译开发平台及程序的编写，实现视频实时采集、H��264编码以及基于改进分层光流法的运动目标进行实时检测，最后采用基于Live555的RTSP服务器完成视频数据的实时传输，实现了远程视频监控及运动目标检测功能。试验结果表明，该系统运动目标检测准确性高，稳定性和实时性较好。%In view of the relative lack of specially designed intelligent video monitoring sys-tem for underground coal mine,a kind of moving obj ects detection system in coal mines based on Hi3516 was designed and implemented�� The system took the Hi3516 as the core processor, through programming and setting up the cross compiler development platform,real-time video capture,H��264 encoding and real-time moving objects detection based on improved hierarchical optical flow method were realized, then the real-time video data transmission was achieved through RTSP server based on Live5 5 5 ,which realized the remote video monitoring and moving obj ects detection��The test results showed that the system had high accuracy of moving obj ects detection,better stability and real-time performance.
