Application of 3D Laser Scanning Technology in Reconstruction Survey of Old Residential Areas
In old community reconstruction projects,the detailed topographic map,elevation map and other basic data are usually needed.In order to solve the problems of large manpower input,long working time and low working efficiency in traditional working methods,this paper takes a reconstruction survey project in an old residential area of Nanchang,Jiangxi province as an example,and introduces the operation flow,data processing and technical points of 3D laser scanning technology.The accuracy of the results is verified with the total station instrument combined with the traditional measuring methods such as steel ruler.
