I'm following this guide and trying to understand whet he does step by step but i got stuck with that line. I want only to copy the area inside the card contour ,save it as another image and after campare that image with other images for detect what card is. python opencv Share Impro...

我对getPerspectiveTransform的参数有点困惑，因为我看不到正确的图像。这是我的代码。original_image变量是包含一个正方形对象(以及其他一些对象)的图像，我希望裁剪该对象并创建一个新图像(类似于下面的Android OpenCV Find Largest Square or Rectangle)。变量p1、p2、p3和p4是图像中最大的正方形/矩形的角坐标。p1...
