Detailed Description

template<class CALIBRATION>
class gtsam::SmartProjectionPoseFactor< CALIBRATION >

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, and that the calibration is the same for all cameras involved in this factor. The factor only constrains poses (variable dimension is 6). This factor requires that values contains the involved poses (Pose3). If the calibration should be optimized, as well, use SmartProjectionFactor instead!
