Abstract

The invention discloses a face posture recognition method, device and e apparatus and a storage medium, and belongs to the technical field of face recognition. The method comprises the following steps: acquiring a region image containing a face region; calling a posture angle recognition model to recognize a face posture in the area image, wherein the posture angle recognition model is a machine learning model with face posture angle recognition capability; wherein the posture angle recognition model is obtained by training a sample face image marked with a sample face posture angle, and the sample face posture angle is any angle selected in a circumferential angle range; and obtaining the human face attitude angle output by the attitude angle recognition model, wherein the human face attitude angle comprises a pitch angle, a yaw angle and a roll angle of the human face relative to a shooting position. The human face posture angle is any angle within the range of the circumferential angle.

Description

technical field [0001] The present application relates to the technical field of face recognition, and in particular to a face gesture recognition method, device, equipment and storage medium. Background technique [0002] Face recognition technology is based on the user's facial features to identify the input face image or video stream. This technology first judges whether there is a face in the input image or video stream. If there is a face, it further obtains the information of each face. The information corresponding to the position and size and the position information of each facial organ can extract the identity features contained in the face according to the above information, and compare the recognized face information with the known face information to know the correspondence of the face. user identity. [0003] Face recognition can identify the state of the face according to the user's facial expression or movement, and the movement of the user's head, such as r...
