Human face angle determination method and device based on computer vision, equipment and medium

The invention discloses a face angle determination method and device based on computer vision, equipment and a medium. The method comprises the following steps: acquiring current video data containing a current video frame and corresponding to a target area; recognizing and processing the current video frame based on the target area detection model, generating a basic face recognition area containing face detection information, and performing external expansion cutting on the basic face recognition area based on the face detection information to generate a target face recognition area corresponding to the current video frame; carrying out key point extraction on the target face recognition area based on an improved target three-dimensional key point detection model, and generating a target face key point set corresponding to the current video frame; and calculating and evaluating the target face key point set based on the basic three-dimensional face key point template and a preset large-angle judgment standa
