摘要
为研究采用"机载LiDAR+倾斜摄影"技术制作的实景三维模型地理精度,以建筑的点、面、体为地理空间特征,采用内外业检测对比的方法,结合数据源分析倾斜影像、LiDAR点云数据对实景三维模型地理精度影响的原因以及分布规律,总结出实景三维模型地理精度检测,可以简化为对建筑楼顶点、楼侧点、楼底点的检测,来评价实景三维模型的地理空间精度。
For the study of using ＂airborne LiDAR＋ tilt photography＂ technology in the production ofreal 3D model of geographical accuracy, building point, area and volume for the geographic features, methods of detection and contrast by inside and outside the industry, combined with the data source analysis of the influence of tilt images of LiDAR point cloud data on the Shi Jingsan dimension model precision and geographic distribution, summary a real 3D model of geo- graphic precision detection can be simplified to the detection of building, building, building the vertex side of the bottom point,to evaluate the real 3D model of geographical space precision.
