The Construction of Simplified Mesh Model Containing the Plane in the Indoor Scene

In order to simulate the indoor scene by constructing a simplified mesh model with plane structure,a fast mesh modeling algorithm was proposed.Firstly,the horizontal and vertical planes were quickly and robustly reconstructed from the noisy mesh by algorithm based on the principle of heat conduction.Then the mesh was simplified by QEM algorithm,and the non-manifold edges were avoided through judging the link condition in the simplification process.Finally,the vertices of the mesh boundaries were classified and processed to ensure the consistency of the topological connection between the planar and non-planar mesh.Taking meshes generated by the TUM-RGBD dataset as input,this algorithm is compared with the Guided Normal Filter algorithm,etc.The experiments show that the algorithm can construct a simplified mesh with consistent topology connectivity,and the reconstruction speed can basically meet the requirements of real-time interaction.
