Description

SPM_ITERATIVE

Levenberg-Marquardt optimization. Requires at least 4 planar or 6 non-planar reference points.

SPM_EPNP

Efficient perspective-n-point camera pose estimation. Requires at least 4 reference points.

SPM_P3P

Complete solution classification for the perspective-three-point problem. Requires exactly 4 reference points to find a unique solution.

SPM_AP3P

An efficient algebraic solution to the perspective-three-point problem. Requires exactly 4 reference points to find a unique solution.

SPM_IPPE

Infinitesimal plane-based pose estimation. Requires at least 4 coplanar reference points.

SPM_IPPE_SQUARE

IPPE specialization for squares. Requires exactly 4 reference points in the following order (hsl: half square length): (-hsl, hsl, 0), (hsl, hsl, 0), (hsl, -hsl, 0), (-hsl, -hsl, 0)

SPM_SQPNP

A consistently fast and globally optimal solution to the perspective-n-point problem. Requires at least 4 reference points.
