I try to calculate the orientation of 2 contours. At the end i want to rotate one contour, so it is in cover with the other one. With my code I get a result, but it isn't that accurate. Also I get the same orientations although the contours is rotated around 90 degrees.
Here is my code:
Moments moments_dxf;
Moments moments_img;
moments_dxf = moments( mcontours_dxf[ alargest_contour_index_dxf ], true );
double theta_dxf_outer = 0.5 * atan( ( 2 * moments_dxf_outer.mu11 ) / ( moments_dxf_outer.mu20 - moments_dxf_outer.mu02 ) );
moments_img = moments( mcontours_image[ alargest_contour_index_img ], true );
double theta_img_outer = 0.5 * atan( ( 2 * moments_img_outer.mu11 ) / ( moments_img_outer.mu20 - moments_img_outer.mu02 ) );
has anyone an idea?
