Detailed Description

If you are using the factor, please cite: L. Carlone, Z. Kira, C. Beall, V. Indelman, F. Dellaert, Eliminating conditionally independent sets in factor graphs: a unifying perspective based on smart factors, Int. Conf. on Robotics and Automation (ICRA), 2014. This factor assumes that camera calibration is fixed, but each camera has its own calibration. The factor only constrains poses (variable dimension is 6). This factor requires that values contains the involved poses (Pose3).
