python opencv 使用pointPolygonTest函数判断点在自定义矩形轮廓内

python opencv判断点在自定义轮廓内
点：point
范围： (x1, y1) 与 (x2, y2) 构成的矩形轮廓

x1, y1, x2, y2 = (0, 0, 300, 300)
point = (220, 110)
testContour = np.array([np.array([x1, y1]), np.array([x2, y1]), np.array([x2, y2]), np.array([x1, y2])])
exist = cv2.pointPolygonTest(testContour, point, True)
print("test result: ", exist)
