The invention discloses a hole detection and repairing method based on a point cloud greedy triangular projection construction model. Point cloud data acquired by means of three-dimensional laser scanning, underwater multi-beam and the like are used as a basis. A point cloud three-dimensional model is constructed according to a greedy triangular projection method; however, the construction qualityof the model is greatly influenced by the relative sparse degree of point clouds. A plurality of model holes are often generated in a three-dimensional model; therefore, the refinement degree of a point cloud greedy triangular projection construction model is improved; according to the method, the area with the hole needs to be rapidly and automatically found, meanwhile, the hole needs to be completely repaired through an optimized algorithm, the value of the complete three-dimensional model with the high refinement degree can be brought into play, and reliable guarantee is provided for subsequent point cloud analysis work.
