基於視訊AI+GIS的創新實踐開發了面向公安行業的二三維一體化服務公安實戰應用。二三維一體化服務公安實戰應用是以“雪亮工程”為背景，把治安防範措施延伸到群眾身邊，發動社會力量和廣大群眾共同監看視訊監控，共同參與治安防範，從而真正實現治安防控“全覆蓋、無死角”。在這套系統中，視訊AI與二三維GIS應用充分結合，實現了基於二三維地圖的視訊AI解析、視訊影象智慧預警、三維融合實景指揮排程。
(1)視訊AI解析應用
在GIS地圖上，基於視訊AI解析應用，實現人員資訊、車輛資訊、探頭資訊、建築資訊的自動識別和上圖。人員資訊主要識別其臉部特徵、體貌特徵、姿態、狀態、著裝顏色、紋理、體型、膚色、髮型等。車輛資訊主要識別車牌號、顏色、車輛型別、品牌、行駛速度、方向、貼膜顏色、改裝標誌、經過時刻、道路等。探頭資訊主要對攝像頭點位資訊進行上圖、實現短視距、最長視距、平均視距、二維可視域、三維可視域等。建築資訊主要識別提取其建築物特徵、建築物內各層、各房間屬性資訊、建築物窗戶等。
(2)視訊影象智慧預警
基於視訊AI解析應用結果，結合二三維GIS地圖，實現人員資訊、車輛資訊、探頭資訊的圖上實時預警、預警資訊查詢、以及預警資訊的統計分析。
(3)三維融合實景指揮排程
三維融合實景指揮排程基於三維GIS實現指揮排程、預案管理、資訊統計、綜合預警等功能，為日常勤務、重大任務提供可視、直觀的決策環境，大大提高作戰效率與輔助決策水平。
