Halcon极坐标逆变字符生成八卦图的玩法

浮生如梦_2024-10-15 15:57

极坐标的逆变换：polar_trans_image_inv(PolarImage : XYTransImage : Row, Column, AngleStart, AngleEnd, RadiusStart, RadiusEnd, Width, Height, Interpolation : )

其中：Row, Column分别为圆环的中心行列坐标， AngleStart, AngleEnd为起始和终止的角度值，RadiusStart, RadiusEnd为起始和终止的半径角度值， Width, Height为输出图片的宽和高。
