Building model construction method of 3D laser point cloud data based on multi-detail feature layer
Nowadays,many scholars have put forward many useful solutions for different types of building modeling,while the fast building modeling method for old residential buildings still needs to be studied.Therefore,a fast building modeling method based on 3 D laser point cloud data is proposed in this paper.Firstly,when original data of the building point cloud obtained,the method can be used to calculate the scale information and extract the characteristic parameters through the denoising and normalization of the point cloud.Secondly,the point cloud elevation is sliced,and the edge and boundary of the sliced block point cloud are fitted and determined respectively,and the digital model surface is constructed through the connection relationship between the layers.Finally,the surface of the above model is spliced and op-timized to complete the construction of the digital model of the whole building,and a residential building in an area is taken as an example to test.The results show that the method proposed in this paper can be used to complete model modeling,and the constructed model has practical engineering applications.So the proposed method has good promotion values and reference significance in the field of 3D point cloud building modeling.
