Many military test ranges worldwide deal with the measuring of position and attitude of moving objects using dedicated tracking mounts which can follow objects at large distances. The main feature to be measured for these studies is the 3D position of the object at different times. Using the 3D position data all kinds of analysis can be performed, e.g. calculating the distance between a missile and a target. Several tracking mounts can be used, positioned at different locations. Recording the direction to the object from different angles results in high accuracy 3D positions. An important tool to obtain this accuracy is TrackEye. The program tracks objects in images automatically, handles the positions of the tracking mounts, integrate different calibrations and corresponding corrections, transforms coordinate systems and calculates the position for all objects.
