摘要
针对城区建筑物密集及其周边植被繁茂的丘陵地区,制订合理高效的测绘方案,采用机载LiDAR与倾斜摄影测量技术,获取实景三维模型和数字正射影像。利用EPS软件二三维联动一体化测图模式,实现二维或三维状态下的地形图测绘。试验结果表明,依据该方法生产地形图的平面精度和高程精度均满足大比例尺地形图测量的要求,为机载LiDAR与倾斜摄影测量技术在实际生产应用提供参考。
In view of the hilly area with dense buildings and lush vegetation around the city,a reasonable and efficient surveying and mapping scheme is made,which adopts airborne LiDAR and oblique photogrammetry technology,get 3D real scene model and digital orthophoto.The topographic map of 2D or 3D state can be surveyed and drawn by EPS software.The experimental results show that the plane accuracy and elevation accuracy of topographic map produced by this method can meet the requirements of large-scale topographic map measurement,and provide a reference for the application of airborne LiDAR and oblique photogrammetry technology in practical production.
