Detailed Description

template<class CALIBRATION>
class gtsam::EssentialMatrixFactor5< CALIBRATION >

Binary factor that optimizes for E and two calibrations Ka and Kb using the algebraic epipolar error (Ka^-1 pA)'E (Kb^-1 pB). The calibrations are assumed different for the two images, but if you use the same key for Ka and Kb, the sum of the two K Jacobians equals that of the K Jacobian for EssentialMatrix4. If you know there is a single global calibration, use that factor instead.

Note: see the comment about priors from EssentialMatrixFactor4: even stronger caveats about having priors on calibration apply here.
