摘要
采用地面三维激光雷达系统,完成了某市13个老旧小区改造建筑立面测绘项目,并在此基础上,统计分析了三维激光点云的精度,检测了建筑立面图的间距精度,其精度可达16.55 mm。相比传统测绘方法,在城镇老旧小区改造中,地面三维激光雷达系统则具有高效率、高精度的优势。
The facades surveying and mapping project of 13 old residential areas in a city was completed by using ground 3D laser radar system.Based on this,the accuracy of 3 D laser point cloud is analyzed statistically,and the spacing accuracy of building facade can be up to 16.55 mm.Compared with the traditional surveying and mapping method,the ground-based three-dimensional lidar system has the advantages of high efficiency and high precision in the reconstruction of the urban old residential area.
