Abstract：The renovation of old houses in urban renewal is an important measure to promote high-quality economic development and improve residents'happiness.However,in complex building surveying and mapping,traditional measurement methods have problems of low efficiency and high operational difficulty.The article combines UAV oblique photography technology with 3D laser scanning technology,utilizing their complementary advantages to enhance the accuracy and all-round coverage capability of building modeling.Through practical case analysis,the application effect of this composite measurement method in complex buildings has been verified.This technical solution can significantly improve the efficiency and accuracy of building measurement,and provide data support for the renovation and upgrading of old buildings.
