摘要
The use of mathematical formulations to retrieve missing data is not usually implemented as an automated computer procedure. The purpose of this paper is to present a simple mathematical formulation that can be used to retrieve the coordinates of markers hidden during a task. A strategy based on the smoothness of the variation of distance between points is devised, which leads to an automated computer procedure for retrieving hidden skin markers or missing joint. coordinates (missing 3D points). This approach has the advantage of not being restricted to the usual rigid-body assumption. (C) 2002 IPEM. Published by Elsevier Science Ltd. All rights reserved.
