The invention relates to the field of monitoring point location blind area detection, and discloses a video monitoring blind area detection method and system based on a road network. The system comprises a monitoring unit, a detection processing unit, a matching elimination unit, and a grid calculation unit. According to the invention, a video monitoring module and a distance monitoring module inthe monitoring unit monitor the external condition of a road, and monitoring signals are transmitted through the detection processing unit, therefore, a point location blind area detection mechanism can be effectively monitored; meanwhile, spatial gridding is conducted on a spatial map, then the road network and the grids are effectively overlapped, non-road-network parts are removed, and the overlapped parts are reserved; and then, a coverage range of the monitoring point location is set, effective visual grid calculation is performed, the detection of the road blind area of the monitoring point location is completed, and the coverage area of the monitoring point location and the mileage of the covered road are effectively obtained.
本发明涉及监控点位盲区检测领域,公开了一种基于路网的视频监控盲区检测方法和系统,包括:监控单元、检测处理单元、匹配消除单元、以及网格计算单元;本发明通过监控单元中的视频监控模块和距离监控模块进行道路外部情况的监测,同时监测信号通过检测处理单元进行传输;从而可以有效的监控点位盲区检测机制;同时将空间地图进行空间网格化,然后将路网与网格进行有效的重叠并剔除非路网部分,保留重叠部分;然后拟定监控点位可以覆盖的范围,进行有效可视化网格计算,完成监控点位道路盲区检测侦测,有效获取监控点位覆盖面积和覆盖道路里程数。
