Problems solved by technology

[0004] However, for the face key point detection in the 3D face model, if the above-mentioned face key point detection algorithm is used, the 3D face model is directly processed and analyzed, and finally the 3D face key point in the 3D face model is obtained. Positioning results, the positioning results of 3D face key points obtained in this way are not accurate enough

Abstract

The embodiment of the invention provides a face key point detection method, device and equipment and a storage medium, and relates to the technical field of artificial intelligence computer vision. The method comprises the following steps: acquiring a three-dimensional face model; projecting the three-dimensional face model from n different visual angles to obtain n two-dimensional face images; detecting corresponding two-dimensional face key points from the n two-dimensional face images; obtaining key point mapping results respectively corresponding to the n two-dimensional face images; and respectively selecting three-dimensional face key points corresponding to the projection view angles from the key point mapping results corresponding to the n two-dimensional face images, and integrating the three-dimensional face key points to obtain a positioning result of the three-dimensional face key points on the three-dimensional face model. According to the technical scheme provided by theembodiment of the invention, the accuracy of detecting the face key points on the three-dimensional face model is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of computer vision of artificial intelligence, and in particular to a face key point detection method, device, equipment and storage medium. Background technique [0002] Face key point detection refers to the detection of key points such as eyeball centers, eye corners, nose tips, mouth corners, and face contours from a given face image. [0003] In related technologies, for the face key point detection of two-dimensional face images, there are relatively mature technologies, such as: ASM (Active Shape Model, active shape model) algorithm, AAM (Active Appearance Model, active appearance model) algorithm , CPR (Cascaded Pose Regression, cascaded posture regression) algorithm, machine learning algorithm, etc. Through the above-mentioned human face key point detection algorithm, the two-dimensional human face image is processed and analyzed, and finally the positioning result of th...
