opencv - 广义霍夫变换 OpenCV Python 模板

Question

我很困惑如何在 openCV Python 中使用广义霍夫变换。当我使用灰度图像的 ROI 设置模板时，它显示此错误:

Incorrect type of self (must be 'GeneralizedHough' or its derivative)

这是我的示例代码:

alg = cv.GeneralizedHoughGuil()
# Simple create template with 1 channel black images with size 5x5
template = np.zeros((5,5))
alg.setTemplate(template)

Answer 1

调用 cv.createGeneralizedHoughGuil而不是 cv.GeneralizedHoughGuil :

alg = cv.createGeneralizedHoughGuil()
template = np.zeros((5,5))
alg.setTemplate(template)
