Three-dimensional face model generation method based on point cloud

The invention discloses a three-dimensional face model generation method based on point cloud, and the method comprises the following steps: S1, calibrating the position relation between the visual angles of a depth camera: S11, collecting corresponding calibration images at different visual angles of the depth camera; s12, calculating an internal parameter matrix and an external parameter matrix of the camera; s2, calibrating a position relationship between the depth camera and the RGB camera, and calculating an internal and external parameter matrix between the depth camera and the RGB camera by acquiring a calibration image; and S3, acquiring three-dimensional point cloud and RGB images, and simultaneously capturing three-dimensional point cloud data and color images with RGB information of the same face at different visual angles by using the binocular depth camera and the RGB camera. According to the three-dimensional face model generation method based on the point cloud, the position relation among the
