Calibration of Target Positions using the Conformal Model and Geometric Algebra

This paper addresses the problem of calibrating the 3D positions of multiple stationary point targets based on the motion analysis of a group of rigidly co-located calibrated cameras. A non-linear solution is developed using the conformal model of Euclidean 3D space. The algorithm is expressed entirely within the computational framework of geometric algebra and geometric calculus. Experiments are performed to evaluate the algorithm and the results show that it performs well and is robust in the presence of noise.
