Irregular target scanning and printing method based on three-dimensional camera

The invention discloses an irregular target scanning and printing method based on a three-dimensional camera, and belongs to the field of three-dimensional reconstruction. The method comprises the following steps: firstly, carrying out camera initialization and communication initialization, and collecting multiple pieces of point cloud data by using a three-dimensional camera; then statistical filtering processing is carried out; then carrying out random sampling consistency estimation, and removing a reference surface; carrying out top projection to realize bottom surface compensation; then carrying out centroid removal operation and rotation transformation; performing registration by using an iterative nearest point algorithm to obtain complete irregular target point cloud data after registration of a plurality of point clouds; smoothing is carried out by using a moving least square algorithm; performing curved surface reconstruction by using a greedy projection triangulation algorithm; and finally, the fil
