Motion capture method for determination of the spatial positions of markers in a 3D volume from 2D digital images for use in motion capture systems so that the marker positions can be related to a coordinate system

摘要

Method for determining the spatial positions of markers in a volume, whereby digital 2D images are obtained using cameras and then processed using a computer. The images are assigned to groups and a bundle comparison method implemented so that from a multiplicity of data sets, 2D positions corresponding to the same marker can be determined. The spatial positions of the markers with respect to a reference coordinate system are determined using the determined marker positions. The invention also relates to a corresponding motion capture system.
