industrial_calibration::RandomCorrespondenceSampler Struct Reference

A correspondence sampler that randomly chooses a specifiable number of correspondence indices with a uniform probablility to use in generating a homography transform.

	RandomCorrespondenceSampler (const std::size_t n_correspondences_, const std::size_t n_samples_, const unsigned seed_=std::random_device{}())
virtual std::vector< std::size_t >	getSampleCorrespondenceIndices () const final override

Public Attributes
const std::size_t	n_correspondences
	Number of total correspondences.
const std::size_t	n_samples
	Number of samples with which to calculate the homography transform. This number must be at least 4. Typically a lower number of samples (i.e. 4) does not produce an accurate homography transform; one quarter to half the total number of correspondences is a good rule of thumb.
const unsigned	seed
	Random seed.
