Sequential estimation in robot vision

This paper introduces an efficient estimation algorithm based on Givens transformations for use in point positioning and updating camera orientation data. In a test, an easy-to-use standard video camera has been applied for image frame generation. The results of camera calibration and an accuracy test using a 3D testfield are presented. The computing times of sequential point positioning and camera orientation are given and in part compared to the values for the simultaneous adjustment. This clearly indicates the superior performance of the sequential procedure. -from Authors
