Paper Abstract

Satellite scanner imaging geometry is quite different from that of the frame camera. The differences play an important role when determining parameters of exterior orientation. This paper discusses current approaches to scanner resection and describes how the accuracy of these approaches may be enhanced by using reconstructed satellite motion information and alternative parameterizations of the unknowns. A new geometric formulation of the resection problem is introduced which uses a point-to-line distance metric instead of the conventional collinearity equations. This is proposed in order to reduce the amount of approximation required for scanner resection, and hence increase accuracy.
