Abstract

Disclosed is a 3D point selection method in an optical motion capture scene. The method comprises the following steps: acquiring a real-time 3D point of a rigid object in an optical motion capture scene at a target moment; calculating the distance between any two of the real-time 3D points; comparing the distance between any two of the real-time 3D points with the distance between any two of the points of the rigid body object in the reference form to obtain a corresponding relation; and determining the corresponding relationship between the real-time 3D point and each point of the rigid body object in the reference form according to the corresponding relationship. Therefore, the corresponding relation between the real-time 3D points and the points of the rigid body object in the reference form can be accurately obtained by comparing the calculated distance between the 3D points with the distances of the points of the rigid body object in the reference form. The corresponding rigid body attitude can be conveniently calculated subsequently, and the calculation amount is reduced.

Description

technical field [0001] The present invention relates to the technical field of motion capture, in particular to a method, device and storage medium for selecting a 3D point in an optical motion capture scene. Background technique [0002] In the existing marker point motion capture system, there are certain requirements for the installation of the rigid body and the marker point, and the characteristics of the rigid body determine the accuracy of the system motion capture to a certain extent. Generally speaking, the optical motion capture system emits infrared light through the group control cameras arranged around the scene, and then receives the infrared light reflected by several infrared photospheres on multiple rigid objects to complete the capture of 2D pixel data of rigid objects. [0003] Then use the captured 2D data to perform 3D reconstruction through triangulation and other methods, so as to restore the 3D point position of the rigid body point in the scene. How...
