Modeling method and device of point cloud model, storage medium and electronic equipment

The invention discloses a modeling method of a point cloud model. The modeling method comprises the following steps: acquiring an initial three-dimensional point cloud; determining a sampling size based on the overall size of the initial three-dimensional point cloud, the scale of a target point cloud model and the point cloud density of the initial three-dimensional point cloud; performing point cloud sampling on the initial three-dimensional point cloud according to the sampling size to obtain a target point cloud; performing normal orientation on each point in the target point cloud; for all points in the target point cloud, every two points form a point pair, and the features of each group of point pairs are determined; associating each group of point pairs with the serial number of the corresponding point pair; and generating a model file of a target point cloud model based on the target point cloud, the normal orientation result of each point in the target point cloud, the features of each group of poin
