3D visualization for heart model from point clouds

In order to improve the efficiency of the ablation operation, this paper proposes a 3D visualization system. In the system, cloud section is used, looking for outer points and eliminating noise-points effectively. And then we adopt Poisson surface reconstruction to achieve 3D reconstruction for scattered point-cloud, which can obtain more ideal geometry. Then, a further optimization is made for the model. The test shows that this system has good reliability and instantaneity.
