35.4、仿射变换实例一

目标：通过仿射变换根据定位find_***_model输出的参数把模板轮廓贴合到实时图像上

read_image (Image11, '1-1.bmp')

dev_set_draw ('margin')

draw_rectangle1 (3600, Row1, Column1, Row2, Column2)

gen_rectangle1 (Rectangle, Row1, Column1, Row2, Column2)

reduce_domain (Image11, Rectangle, ImageReduced)

create_shape_model (ImageReduced, 'auto', rad(-180), rad(360), 'auto', 'auto', 'use_polarity', 'auto', 'auto', ModelID)

get_shape_model_contours (ModelContours, ModelID, 1)

find_shape_model (Image11, ModelID, rad(-180), rad(360), 0.5, 1, 0.5, 'least_squares', 0, 0.9, Row, Column, Angle, Score)

 

if (|Score|>0)

*方法一

* dev_display_shape_matching_results (ModelID, 'red', Row, Column, Angle, 1, 1, 0)

*方法二

* hom_mat2d_identity (HomMat2DIdentity)

* hom_mat2d_scale (HomMat2DIdentity, 1, 1, 0, 0, HomMat2DScale)

* hom_mat2d_rotate (HomMat2DScale, Angle, 0, 0, HomMat2DRotate)

* hom_mat2d_translate (HomMat2DRotate, Row, Column, HomMat2DTranslate)

* affine_trans_contour_xld (ModelContours, ContoursAffinTrans, HomMat2DTranslate)

* dev_display (ContoursAffinTrans)

*方法三

vector_angle_to_rigid (0, 0, 0, Row, Column, Angle, HomMat2D)

hom_mat2d_scale(HomMat2D, 1, 1, 0, 0, HomMat2DScale1)

affine_trans_contour_xld (ModelContours, ContoursAffinTrans1, HomMat2DScale1)
