發(fā)布時間:2018-12-15 04:25
【摘要】:為解決LBS技術中組件式地理信息服務在車輛監(jiān)控應用中研發(fā)成本和應用門檻較高的問題,基于第三方地圖服務,研究分別從數(shù)據層、中間處理層與用戶交互層出發(fā),實現(xiàn)坐標系統(tǒng)轉換、空間數(shù)據篩選與圖形疊加等監(jiān)控數(shù)據地圖可視化關鍵技術,將數(shù)據層中不同源空間數(shù)據篩選轉換成用戶層中圖形可視化交互信息。研究實現(xiàn)實時位置追蹤與車輛行駛軌跡等基礎功能,驗證了監(jiān)控數(shù)據地圖可視化技術的可行性;并測試空間數(shù)據篩選技術的有效性,數(shù)據篩選率最高為30%。
[Abstract]:In order to solve the problem of high R & D cost and application threshold of component GIS in vehicle monitoring and control application in LBS technology, based on the third party map service, the paper starts from the data layer, the intermediate processing layer and the user interaction layer, respectively. The key technologies of monitoring data map visualization, such as coordinate system transformation, spatial data filtering and graph superposition, are realized, and different homologous spatial data filtering in data layer is transformed into graphical visual interactive information in user layer. The basic functions of real-time position tracking and vehicle track are studied to verify the feasibility of the visualization technology of monitoring data map, and the validity of spatial data screening technology is tested. The data screening rate is up to 30%.
