Title:
HUMAN BODY POSTURE ESTIMATION METHOD AND APPARATUS, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/257378
Kind Code:
A1
Abstract:
Embodiments of the present application provide a human body posture estimation method and apparatus, and a terminal device. The method comprises: extracting first feature data of an image, inputting the first feature data to a two-dimensional human body posture estimation model, and outputting a two-dimensional human body posture key point feature map, a two-dimensional human body joint connection feature map, and second feature data by means of the two-dimensional human body posture estimation model; inputting the first feature data and the second feature data to a three-dimensional human body posture estimation model, and outputting a three-dimensional human body posture key point feature map by means of the three-dimensional human body posture estimation model; and according to the two-dimensional human body posture key point feature map, the two-dimensional human body joint connection feature map, and the three-dimensional human body posture key point feature map, determining two-dimensional positions of human body key points of each human body in the two-dimensional human body posture key point feature map, and three-dimensional positions of the human body key points of each human body. In this way, two-dimensional positions and three-dimensional positions of the human body key points can be detected simultaneously, thereby reducing time overhead.
