Package boofcv.alg.geo.trifocal

Class TrifocalAlgebraicPoint7

java.lang.Object

boofcv.alg.geo.trifocal.TrifocalLinearPoint7

boofcv.alg.geo.trifocal.TrifocalAlgebraicPoint7

public class TrifocalAlgebraicPoint7
extends TrifocalLinearPoint7

Initially computes the trifocal tensor using the linear method TrifocalLinearPoint7, but then iteratively refines the solution to minimize algebraic error by adjusting the two epipoles. The solution will enforce all the constraints and be geometrically valid. See page 395 in [1].

Note: This works with planes!
