1. A calibration process for mapping the angular and spacing positions of referencing cameras, comprisingpositioning a calibration tool having two reflectors secured at predetermined positions at a known distance away from each other in the viewing range of said cameras, moving said calibration tool three-dimensionally in said viewing range, mapping several intermediate positions of said calibration tool by said referencing cameras and converting the resulting data by means of a computer unit individually into three-dimensional coordinates of the reflectors or calibration tool, and computing said angular and spacing positions of said cameras from said three-dimensional coordinates of said reflectors or calibration tool by means of said computer unit.
