摘要
Abstract
The shapes and structures of urban irregular buildings are complex and diverse.Both unmanned aerial vehicle(UAV)oblique photography and ground-based three-dimensional(3D)laser scanning technologies suffer from occlusion issues,which affect the quality of 3D models.To improve the accuracy of the completion survey results for irregular build-ings,this study used UAV oblique photography and laser scanning point-cloud data as the basis and applied the iterative clos-est point(ICP)algorithm for point-cloud registration and fusion.A 3D model is reconstructed,and an experiment based on a specific irregular sports venue demonstrates that this method significantly enhances the model's precision.The error distri-bution becomes more uniform,and it compensates for defects such as model gaps and blurry textures that are common with single technology-based models.This approach provides accurate and visualized model data for the completion survey of irregular buildings.关键词
