Embodiment Construction
[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0042] Compared with other modal data, the depth data is greatly affected by the collection distance and camera parameters in terms of overall style, void rate, and three-dimensional accuracy. The occlusion of glasses, hair, and accessories will also bring uncertainty to the depth data. Impact. These factors will increase the difficulty of face r...

The embodiment of the invention provides a face recognition method and device, electronic equipment and a storage medium. The method comprises the steps of determining a to-be-recognized face depth map; based on the face depth map, determining a face parameterized point cloud map; inputting the human face parameterized point cloud picture into a three-dimensional human face reconstruction networkto obtain a three-dimensional human face reconstruction model output by the three-dimensional human face reconstruction network; and inputting the three-dimensional face reconstruction model into a feature extraction network to obtain face features output by the feature extraction network, the face features being used for face recognition. According to the method and device, the electronic equipment and the storage medium provided by the embodiment of the invention, the face recognition accuracy is improved, and the generalization ability of depth data of different cameras is enhanced.
Description
technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a face recognition method, device, electronic equipment and storage medium. Background technique [0002] With the development of depth sensor technology, it becomes possible to obtain the depth information of the target in real time. The 3D face recognition technology based on depth information can well solve the problem of poor anti-counterfeiting ability of 2D face recognition, thereby further improving the effect of face recognition and has broad application prospects. [0003] In the existing technology, when using depth data for face recognition, due to the uneven quality of depth data at different distances, different depth cameras will have different point cloud styles, and the face may have occlusions, holes, etc. Low recognition accuracy and poor generalization ability to depth data from different cameras. Contents of the invention [0004] Embodimen...
