python opencv实现切变换 不裁减图片

本文实例为大家分享了python opencv实现切变换的具体代码，供大家参考，具体内容如下 # -*- coding:gb2312 -*- import cv2 from math import * import numpy as np img = cv2.imread("3-2.jpg") height,width=img.shape[:2] degreeAffine=45 #切变换最后结果 heightAffine=height widthAffine=int(2*height*tan(radians(degreeAffine))+width) # 随意两点得到仿射变换矩阵 # poi
