Class TrifocalExtractEpipoles

java.lang.Object

boofcv.alg.geo.trifocal.TrifocalExtractEpipoles

public class TrifocalExtractEpipoles
extends java.lang.Object

Extracts the epipoles for views 2 and 3 with respect to view 1 from the trifocal tensor. Epipoles are found in homogeneous coordinates. Singular value decomposition is used to compute each vector and is robust to noise and epipoles will have a norm of one..

Properties:

• e2^T*F12 = 0
• e3^T*F13 = 0

where F1i is a fundamental matrix from image 1 to i.

public void process(TrifocalTensor tensor,
                    Point3D_F64 e2,
                    Point3D_F64 e3)

Extracts the epipoles from the trifocal tensor. Extracted epipoles will have a norm of 1 as an artifact of using SVD.

Parameters:

tensor - Input: Trifocal tensor. Not Modified

e2 - Output: Epipole in image 2. Homogeneous coordinates. Modified

e3 - Output: Epipole in image 3. Homogeneous coordinates. Modified
