Abstract

The invention relates to a human body light spot label identification method and device, a computer device and a storage medium. The method comprises the steps of obtaining an image containing light spots; identifying light spots in the image; numbering the light spots according to preset conditions, obtaining the positions of human body key points obtained through calculation according to inertial sensor measurement data, matching the numbered light spots with the human body key points, obtaining the corresponding matching results, calculating the credibility of the matching results, and whenthe credibility is larger than the preset credibility, matching the light spots with the human body key points. By recognizing the corresponding relation between the light spots and the key points ofthe human body through the inertial sensor and the image data, the corresponding matching result is obtained, the credibility of the matching result is judged, the matching result meeting the presetcredibility serves as the final recognition result, and the recognition accuracy is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a tag recognition method, device, computer equipment and storage medium for light spots on a human body. Background technique [0002] The hybrid motion capture system is composed of a whole body inertial sensor and optical marking points installed on the key points of the human body. The optical marking points are referred to as light points for short. Each light point worn on an actor corresponds to a tag information, indicating the actor where it is located and the number of the wearing part. When the light point is visible to multiple groups of infrared cameras of the optical positioning system, the optical positioning system can detect and obtain the position of the light point in the spatial optical coordinate system. However, the label information of the light spot cannot be directly obtained, and the optical positioning system cannot know which part of th...
