Abstract
Motion analysis systems are currently used in a number of applications. In space research, this apparatus is useful in the study of astronauts' movements in weightlessness. However, the systems that are available on the market do not allow for easy identification of the markers held by the subject when the luminous environment is not controlled. The utilization of active coded targets allows these markers to be identified automatically and without ambiguity. This article presents a possible form of coding, called temporal asynchronous coding of active targets. A prototype integrating this coding has been developed in collaboration with an industrial partner. The implementation of this system, and certain experiments carried out, are set out in this document.
