POSE RECOGNITION METHOD AND APPARATUS BASED ON TWO-DIMENSIONAL CAMERA, AND DEVICE AND STORAGE MEDIUM

摘要

A pose recognition method and apparatus based on a two-dimensional camera, and a device and a storage medium, which relate to the field of artificial intelligence. The method comprises: acquiring, by means of a two-dimensional camera, a human body image of a human body to be subjected to recognition (S1); according to the human body image, extracting body contour information, pose information and gender information of said human body (S2); generating an SMPL model according to the body contour information, the pose information and the gender information (S3); acquiring a 3D node feature from the SMPL model (S4); extracting a 2D node feature of said human body from the human body image (S5); generating an error function according to the 3D node feature and the 2D node feature (S6); adjusting the SMPL model according to the error function, and extracting a target 3D joint feature from the adjusted SMPL model (S7); acquiring skeleton information according to the target 3D joint feature (S8); and performing pose analysis according to the skeleton information (S9). The pose recognition method and apparatus based on a two-dimensional camera, and the device and the storage medium can be applied to the field of blockchains, and can accurately recognize a pose of a human body to be subjected to recognition.
