Abstract

The invention relates to the technical field of artificial intelligence, in particular to a three-dimensional human body posture estimation method and device, equipment and a storage medium, and the method comprises the steps: collecting a picture or video frame of a target human body; the picture or the video frame of the target human body is input into a preset three-dimensional human body posture estimation model, a three-dimensional human body posture estimation result of the target human body is obtained, and the preset three-dimensional human body posture estimation model is obtained by training a semantic graph convolutional neural network based on the target key point of the reference human body; and recognizing the actual motion state of the target human body based on the three-dimensional human body posture estimation result. Therefore, the problems of poor real-time performance, poor application effect and the like of three-dimensional human body posture estimation in related technologies are solved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular, to a three-dimensional human body pose estimation method, device, equipment and storage medium. Background technique [0002] 3D human pose estimation predicts the 3D coordinate information of human joint points in a given world coordinate system by extracting and analyzing object information from pictures and video streams. 3D human pose estimation helps to analyze the motion state of the human body in the picture, and is of great significance to the prediction of pedestrian motion trends and the detection of sudden and dangerous events. [0003] With the rapid development of deep learning theory and technology, it has also received more and more attention and applications in the field of 3D human pose estimation. There are two main frameworks for 3D human pose estimation based on deep learning, one is an end-to-end framework, and the other is a two-...
