ArcEngine根据栅格文件获取x,y和高程信息

选择三维点云的点，返回坐标： H = CLICKA3DPOINT(POINTCLOUD) shows a 3D point cloud and lets the user % select points by clicking on them. The selected point is highlighted % and its index in the point cloud will is printed on the screen. % POINTCLOUD should be a 3*N matrix, represending N 3D points. % Handle to the figure is returned. % % other functions required: % CALLBACKCLICK3DPOINT mouse click callback function % ROWNORM returns norms of each row of a matrix % % To test this function ... % pointCloud = rand(3,100)*100; % h = clickA3DPoint(pointCloud); % % now rotate or move the point cloud and try it again. % (on the figure View menu, turn the Camera Toolbar on, ...) % % To turn off the callback ... % set(h, 'WindowButtonDownFcn','');

VLP-16激光雷达扫描的原始文件为pcap文件，本代码读取VLP-16原始扫描文件对应TXT文件，对文件进行提取、计算获得三维扫描点坐标。
