AI Technical Summary

Problems solved by technology

The problem with this is that when the number of marker points or the number of cameras is large, the calculation of the three-dimensional position coordinates of each marker point will become very time-consuming due to the increase in the number of pixels

Abstract

The invention discloses a method for identifying a marking point, comprising: acquiring a moving image of an object captured by a camera, and numbering pixels in the moving image of the object from 0 to n-1, wherein n is the moving image of the object the number of pixels in the image; call the graphics processor to create n-1 thread groups in the image processor; in the i-th thread group created, the moving image of the object is judged by threads executed in parallel Whether there is a track intersection between pixel i and pixel j in , where i, j are the numbers of pixel points, 1≤i≤n‑1, 0≤j

Description

technical field [0001] The present invention relates to the technical field of motion capture, and in particular, to a method, apparatus, device and storage medium for identifying a marker point. Background technique [0002] Currently, motion capture technology is widely used in virtual reality (VR) games or some somatosensory games. The so-called motion capture refers to setting trackers (such as reflective markers) at key parts of moving objects, capturing the position of the tracker, and then processing the data of three-dimensional space coordinates by computer. When the data is recognized by the computer, it can be used in animation production, gait analysis, biomechanics, ergonomics and other fields. [0003] In the existing optical motion capture system, the motion gesture recognition and trajectory tracking of the target object are generally realized by capturing the motion trajectory of the reflective markers. In this process, the optical motion capture system ne...
