Paper Abstract

This paper introduces an improved 6DOF measurement method for the non-overlapping multi-camera systems. In contrast to the existing equal-weighted bundle adjustment methods, the proposed method assigns an uncertainty based weight to each of the non-overlapping cameras. The measurement uncertainty evaluation framework is established based on the implicit function theorem. The weight assignment criterion enables the camera in a better observation condition to provide stronger constraints. The 6DOF parameters are obtained by optimizing the uncertainty-weighted space resection model with the nonlinear squares solver. The experiment results demonstrate the robustness of the proposed method to cope with poor observation conditions.
