vector_angle_to_rigidvector_angle_to_rigidVectorAngleToRigidvector_angle_to_rigidVectorAngleToRigidVectorAngleToRigid computes a rigid affine transformation, i.e., a
transformation consisting of a rotation and a translation, from a point
correspondence and two corresponding angles and returns it as the
homogeneous transformation matrix HomMat2DHomMat2DHomMat2DHomMat2DHomMat2DhomMat2D. The matrix consists of 2
components: a rotation matrix R and a
translation vector t (also see
hom_mat2d_rotatehom_mat2d_rotateHomMat2dRotatehom_mat2d_rotateHomMat2dRotateHomMat2dRotate and hom_mat2d_translatehom_mat2d_translateHomMat2dTranslatehom_mat2d_translateHomMat2dTranslateHomMat2dTranslate):
The coordinates of the original point are passed in
(Row1Row1Row1Row1Row1row1,Column1Column1Column1Column1Column1column1), while the corresponding angle is passed in
Angle1Angle1Angle1Angle1Angle1angle1. The coordinates of the transformed point are passed in
(Row2Row2Row2Row2Row2row2,Column2Column2Column2Column2Column2column2), while the corresponding angle is passed in
Angle2Angle2Angle2Angle2Angle2angle2. The following equation describes the transformation of the
point using homogeneous vectors:
In particular, the operator vector_angle_to_rigidvector_angle_to_rigidVectorAngleToRigidvector_angle_to_rigidVectorAngleToRigidVectorAngleToRigid is useful to
construct a rigid affine transformation from the results of the matching
operators (e.g., find_shape_modelfind_shape_modelFindShapeModelfind_shape_modelFindShapeModelFindShapeModel or best_match_rot_mgbest_match_rot_mgBestMatchRotMgbest_match_rot_mgBestMatchRotMgBestMatchRotMg),
which transforms a reference image to the current image or (if the parameters
are passed in reverse order) from the current image to the reference image.
HomMat2DHomMat2DHomMat2DHomMat2DHomMat2DhomMat2D can be used directly with operators that transform data
using affine transformations, e.g., affine_trans_imageaffine_trans_imageAffineTransImageaffine_trans_imageAffineTransImageAffineTransImage.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
