Application of Regional Sampling in Underground Space 3D Modeling
摘要
Abstract
Compared with the many limitations of traditional surveying and mapping methods,3D laser scanning technology has more signifi-cant advantages in underground space,but the problem of point cloud redundancy also increases the application burden of results.Aiming at this problem,we studied the data acquisition method of underground space,divided the point cloud into regions according to the curvature,and com-pleted the regional sampling at first.Then,taking a basement for example,we used the polygon modeling method to complete the dioramas recon-struction of basement.Finally,we evaluated the model accuracy,and verified the reliability of this method,which could provide a case reference for 3D modeling of underground space.关键词
