Brief description of a movement of the type of solid indeformable of a set of markers disposed on the anatomical elements, in particular of the human body.

摘要

The process comprises the following steps: at least three markers are placed on or in the part of the anatomy of the subject; the discrete spatial trajectories of the markers are recorded as the subject moves; the markers which are most stable in position relative to one another are determined on each image and these markers are used to establish an orthonormated mark on each image; the marker co-ordinates in these marks are expressed; the reference spatial configuration of the dimensionally-stable solid type is calculated for all the markers involved by an operation for averaging the co-ordinates of these markers; these operations are repeated in order to process the entire movement recorded. The invention is used in particular in anthropometric robotics, medicine or biomechanics.
