描述

vector_angle_to_rigidvector_angle_to_rigidVectorAngleToRigidVectorAngleToRigidVectorAngleToRigidvector_angle_to_rigid 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 HomMat2DHomMat2DHomMat2DHomMat2DhomMat2Dhom_mat_2d. The matrix consists of 2 components: a rotation matrix R and a translation vector t (also see hom_mat2d_rotatehom_mat2d_rotateHomMat2dRotateHomMat2dRotateHomMat2dRotatehom_mat2d_rotate and hom_mat2d_translatehom_mat2d_translateHomMat2dTranslateHomMat2dTranslateHomMat2dTranslatehom_mat2d_translate):

The coordinates of the original point are passed in (Row1Row1Row1Row1row1row_1,Column1Column1Column1Column1column1column_1), while the corresponding angle is passed in Angle1Angle1Angle1Angle1angle1angle_1. The coordinates of the transformed point are passed in (Row2Row2Row2Row2row2row_2,Column2Column2Column2Column2column2column_2), while the corresponding angle is passed in Angle2Angle2Angle2Angle2angle2angle_2. The following equation describes the transformation of the point using homogeneous vectors:

In particular, the operator vector_angle_to_rigidvector_angle_to_rigidVectorAngleToRigidVectorAngleToRigidVectorAngleToRigidvector_angle_to_rigid is useful to construct a rigid affine transformation from the results of the matching operators (e.g., find_ncc_modelfind_ncc_modelFindNccModelFindNccModelFindNccModelfind_ncc_model), 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.

HomMat2DHomMat2DHomMat2DHomMat2DhomMat2Dhom_mat_2d can be used directly with operators that transform data using affine transformations, e.g., affine_trans_imageaffine_trans_imageAffineTransImageAffineTransImageAffineTransImageaffine_trans_image.

运行信息

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
