The idea of laser scanning is to convert the point cloud to BIM model. Every details of a project is captured and based on the information 3D model is created which includes every nook and corner properly modelled. 3D scanning helps the different stages of construction like 3D model creation, visualization, animation, rendering and quality inspection. This process helps to keep record of any project which is already built. Basically the modelling standard that is followed here is LOD 400. It helps to take decision quickly mainly for renovating work.
