Abstract
In the process of real-time 3D modeling of urban renewal data,there may be cumulative errors in point cloud data registration,which can cause the registered point cloud data to deviate from the original position and reduce the accuracy of 3D modeling.To address this issue,the article proposes a real-time 3D modeling method for urban renewal data based on multi-source point cloud fusion technology.This method combines point cloud data from two different sources,namely LiDAR point cloud and photogrammetric point cloud,and fuses them through registration.Based on the fused point cloud data,extract the skeleton lines in the urban environment and use them as a basis for 3D modeling.By quantifying the cumulative error of point cloud registration fusion and using spatiotemporal redundancy as a constraint to mitigate the impact of errors.On this basis,add point cloud data and construct the corresponding 3D model.The results show that this method has high modeling accuracy,with a root mean square error of about 0.47 m.关键词
