Use the OpenCV function cv::getRotationMatrix2D to obtain a \(2 \times 3\) rotation matrix; Theory What is an Affine Transformation? A transformation that can be expressed in the form of a matrix multiplication (linear transformation) followed by a vector addition Aug 25, 2018 · cv2. cv2. The code sample uses linear interpolation, 1 degree rotation, and no NaN values. def warpAffine(src, M, dsize, dst=None, flags=None, borderMode=None, borderValue=None) src：输入图像; M：运算矩阵，2行3列的，数据类型要求是float32位及以上; dsize：运算后矩阵的大小，也就是输出图片的尺寸; dst：输出图像 Aug 12, 2021 · cv2. warpAffine () cv2. By setting the mode to BORDER_CONSTANT it will use a constant value for border pixels (i.
