Abstract
A system for tracking a moving target having up to six degrees of freedom and rapidly determining positions of the target, said system includes an easy to locate precision optical target fixed to the target. This system includes at least two cameras positioned so as to view the optical camera from different directions with each of the at least two cameras being adapted to record two dimensional images of the precision optical target defining precise target point. A computer processor is programmed to determine the target position of x, y and z and pitch, roll and yaw. In an embodiment, the system can be configured to utilize an iteration procedure whereby an approximate first-order solution is proposed and tested against the identified precise target points to determine residual errors which can be divided by the local derivatives with respect to each component of rotation and translation, to determine an iterative correction.
