The Application of 3D Laser Scanning Technology in Urban Renewal Measurement
This paper takes the renewal and reconstruction project of old streets in Ningbo City as an example to study the application of 3D laser scanning technology in the renewal of old streets.Firstly,the 3D laser scanner is used to collect the street point cloud data,and then the point cloud is processed through splicing,denoising,and the Computer-Aided Design(CAD)is introduced to draw the building facade line graphics,and then the 3D digital model of the street is constructed by combining 3ds Max and Unity3D software.The practice shows that the 3D laser scanning technology can quickly and accurately reconstruct building facades,and the accuracy meets the requirements of relevant specifications,which can meet the application needs of the renewal and reconstruction of old streets.
