Three-dimensional attitude information restoration method and device

Abstract

The invention discloses a three-dimensional attitude information restoration method and device, and the method comprises the steps: obtaining a first front image, photographed by a camera device, of a current human body; identifying a plurality of joints in the first front image, and determining length information of a rigid skeleton corresponding to each joint in the plurality of joints in the first front image; acquiring a second front image shot by the current human body after the posture of the current human body is changed by facing the camera device, changing the posture under the condition that the hip joint connecting line of the current human body is parallel to the imaging plane of the camera device, and keeping the distance between the current human body and the imaging plane of the image unchanged; identifying a plurality of joints in the second front image, and determining projection coordinate position information of a rigid skeleton corresponding to each joint in the plurality of joints on an image imaging plane; and restoring the posture information of the current human body in a third dimension orthogonal to the imaging plane. The acquisition cost of model samples and the calculation capability requirement of a training model are reduced, and the calculation amount is greatly reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for restoring three-dimensional posture information. Background technique [0002] In recent years, with the rapid development of artificial intelligence, especially in the field of image recognition, many excellent algorithms have been born, and the level of image recognition is constantly improving. However, human body pose recognition is a very popular sub-field in the current image recognition field. By using various algorithms, the accuracy of human body pose recognition is also constantly improving. [0003] In recent years, the degree of refinement of human body recognition has been improved from two-dimensional to three-dimensional. To perform accurate three-dimensional human body posture recognition, in related technologies, it is generally necessary to use three-dimensional information of the human body for training. Such information includes voxels...
