Web2 de jan. de 2024 · This method accepts an input image and an angle to rotate it by. We assume we’ll be rotating our image about its center (x, y) -coordinates, so we determine these values on lines 44 and 45. Given these coordinates, we can call cv2.getRotationMatrix2D to obtain our rotation matrix M ( Line 50 ). Web21 de dez. de 2024 · Imgproc.getRotationMatrix2D(Point center, double angle, double scale) Parameters: center – Center of the rotation in the source image.; angle – Rotation angle in degrees.
