*** 方法1 刚性仿射变化 推荐
* vector_angle_to_rigid (Row, Column, 0,Row1[i], Column1[i], Angle[i], HomMat2D1)
* affine_trans_contour_xld (ContoursAffineTrans, ContoursAffineTrans1, HomMat2D1)

** 方法2 仿射变化
hom_mat2d_identity (HomMat2DIdentity)
*** Row1[i]-Row 要移动的X左边
*** Column1[i]-Column 要移动的Y坐标
hom_mat2d_translate (HomMat2DIdentity, Row1[i]-Row,Column1[i]-Column, HomMat2DTranslate)
hom_mat2d_rotate (HomMat2DTranslate, Angle[i], Row1[i],Column1[i], HomMat2DRotate)
