       基于视频AI+GIS的创新实践开发了面向公安行业的二三维一体化服务公安实战应用。二三维一体化服务公安实战应用是以“雪亮工程”为背景,把治安防范措施延伸到群众身边,发动社会力量和广大群众共同监看视频监控,共同参与治安防范,从而真正实现治安防控“全覆盖、无死角”。在这套系统中,视频AI与二三维GIS应用充分结合,实现了基于二三维地图的视频AI解析、视频图像智能预警、三维融合实景指挥调度。

  (1)视频AI解析应用

  在GIS地图上,基于视频AI解析应用,实现人员信息、车辆信息、探头信息、建筑信息的自动识别和上图。人员信息主要识别其脸部特征、体貌特征、姿态、状态、着装颜色、纹理、体型、肤色、发型等。车辆信息主要识别车牌号、颜色、车辆类型、品牌、行驶速度、方向、贴膜颜色、改装标志、经过时刻、道路等。探头信息主要对摄像头点位信息进行上图、实现短视距、最长视距、平均视距、二维可视域、三维可视域等。建筑信息主要识别提取其建筑物特征、建筑物内各层、各房间属性信息、建筑物窗户等。

  (2)视频图像智能预警

  基于视频AI解析应用结果,结合二三维GIS地图,实现人员信息、车辆信息、探头信息的图上实时预警、预警信息查询、以及预警信息的统计分析。

  (3)三维融合实景指挥调度

  三维融合实景指挥调度基于三维GIS实现指挥调度、预案管理、信息统计、综合预警等功能,为日常勤务、重大任务提供可视、直观的决策环境,大大提高作战效率与辅助决策水平。
