一. cv2.getRotationMatrix2D(center, angle, scale) 1.1 参数说明 returns:返回下面的2*3行列式,注:α=cosθ,β=sinθ 还是不太懂的话参考:cv2.getRotationMatrix2D的旋转矩阵的正确形式-CSDN博客 二、cv2.warpAffine(src, M, dsize, dst, flags, borderMode, borderValue) 2.1 参数说明 2.2 flags 值说明...
在OpenCV-Python中,图像旋转是常见的几何变换之一。下面我们将介绍几种常用的图像旋转方法:cv.warpAffine、cv.getRotationMatrix2D、cv.rotate和np.rot90。1. cv.warpAffinecv.warpAffine是一个用于执行仿射变换的函数,其中包括旋转操作。该函数接受三个参数:输入图像、变换矩阵和输出图像。变换矩阵可以通过cv.getRotation...
