Sažetak
Video-based systems for three-dimensional reconstruction during the course of biomechanical analysis are today very popular and common. One of the pre-conditions when using such a systems is so-called camera calibration. The objective of calibration is to determine a set of camera model parameters that describe the mapping between 3D reference coordinates (calibration points) and 2D image coordinates. Traditional approach is by the means of calibration cage. Although very effective and still present in many today&#8217 ; ; ; ; s operating systems, calibration cages tend to be replaced more and more through calibration plane or stick (wand). Using calibration plane or wand make such a 3D reconstruction system a lot more user-friendly [1]. On the other hand, calibration/reconstruction algorithms become more complex and the reconstruction accuracy using only plane/wand is likely to be impaired. The aim of this paper was to investigate these three different types of calibration.
