Placement of Composed LED Light Sources for an Inverse Triangulation Motion Capture System with Reflexive Spherical Markers

Article Preview

Abstract:

This paper investigates the problem of composed LED light sources placement for a particular case of motion capture with reflexive spherical markers in Gait Analysis in a controlled lighted environment. After the addressed problem is introduced the way the rays are propagated from the individual LEDs to the pixel array of video camera is computed. Based on this calculus the number of ray hits on distinct pixels is computed for a marker placed in the workspace. Next by varying some scene parameters we obtain the total number of hits on the overall set of makers placed in the scene and based on this number we obtain finally the best placement for the composed LED light sources using an iterative approach.
