无人机倾斜影像数据自动生成等高线方法

A Method for Automatic Generation of Contour Lines from Tilt Image Data of UAV

在地形图生产过程中,等高线的采集编译需要占用大量时间,且对作业人员经验要求较高。为此,利用Context Capture软件生成倾斜影像点云,利用Terrasolid软件功能模块提取地面点及关键地面点以获取最终地面点,最终生成矢量等高线。等高线成果经过编译修改后,进而为地形图生产提供可靠的等高线数据,提高等高线生产效率和地形图生产效率。

In the process of topographic map production,it takes a lot of time to collect and compile contour line,and it requires high experience of operators.To this end,the paper aims to generate tilted image point cloud by Context Capture software,extract ground points and critical points by the function module of Terrasolid software to obtain the final ground points,and generate vector contour lines based on the final critical ground points.After compilation and modification,the contour results can provide reliable contour data for the production of topographic maps and improve the production efficiency of contour lines and topographic maps.
