Interactive three-dimensional point cloud reconstruction method and system, storage medium and electronic equipment

The invention relates to the field of meta-universe digital twin smart cities, and provides an interactive three-dimensional point cloud reconstruction method and system, a storage medium and electronic equipment, and the method comprises the steps: obtaining urban region three-dimensional point cloud data of a target urban region; performing grid reconstruction on the three-dimensional point cloud data of the urban area to obtain a grid reconstruction result; obtaining an expected patch number input by a user; and folding the edge with the minimum edge folding cost in the grid reconstruction result until the number of simplified grid patches of the grid obtained after folding is smaller than the expected patch number, and obtaining a grid simplification result. According to the interactive three-dimensional point cloud reconstruction method, the edge with the minimum edge folding cost in the grid reconstruction result is folded to realize the simplification of the grid, the folding cost generated in the grid
