Face recognition optimization method and device

The invention provides a face recognition optimization method. The face recognition optimization method comprises the following steps: acquiring video data acquired by a camera; determining a face posture in the video data by utilizing a corresponding relation of coordinates of the face key points in the video data in an image coordinate system and a world coordinate system; and correspondingly adjusting a yaw angle of the camera by using the face posture so as to collect a front face image in a face recognition process. 本发明提供了一种人脸识别优化方法，包括：获取所述摄像机采集到的视频数据；利用所述视频数据中的人脸关键点在图像坐标系和世界坐标系中的坐标的对应关系确定出所述视频数据中的人脸姿态；以及利用所述人脸姿态对应地调整所述摄像机的偏航角以便于在人脸识别过程中采集正面人脸图像。
