Sažetak
3D kinematic systems based on the images acquired by cameras are one of the most popular tools for a human motion analyses. Prior to the actual reconstruction a camera calibration procedure is needed. Originally 3D calibration cages were utilized for that purpose, but nowadays a vast majority of commercial systems rely on the wand calibration. When the highest degree of accuracy is requested, than using 3D calibration cage is often recommended over the wand calibration. On the other hand, from a user point of view a wand calibration is generally regarded as the most user friendly. A substantial ‘ intermediate’ solution would be using 2D calibration plate. Interestingly, there could be hardly found any trace that commercial 3D kinematic systems ever relied on 2D calibration plate. The purpose of this study was to investigate quantitative and qualitative aspects of calibrating the 3D kinematic system using 2D calibration plate.
