Abstract: Obtained from the surface of a real scene, the point cloud is a useful representation with respect to real world geometric simulation. We employ point cloud to represent the scene, whose integration into CAD system poses greater challenges and thus causes this topic to be covered less frequently. A registration based perception method is introduced to identify the interest object and calculate its orientation based on which the virtual models are superimposed. According to the hierarchical geometric relationships between the recognised part and the other unknown parts, each component can be installed in the correct position and orientation in the point cloud based scene. Our experiments show that the point cloud environment is useful for virtual assembly simulation. The interaction performed in point cloud space will provide more intuitive, more natural experiences than those in 2D image space.

Keywords: point cloud representation; virtual assembly; assembly constraints; simulation.
