尝试执行BGR到二进制阈值转换时，出现以下错误。
imgthreshhold = cv2.inRange(img, cv2.cv.Scalar(3,3,125), cv2.cv.Scalar(40,40,255)) AttributeError: 'module' object has no attribute 'cv'
以下是完整的程序。
import cv2
cap = cv2.VideoCapture(0)
#help(cv2)
while cap.isOpened():
#BGR image feed from camera
ret, img = cap.read()
cv2.imshow('output', img)
#BGR to grayscale
img2 = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
cv2.imshow('grayscale', img2)
#BGR to binary(RED) thershholded
imgthreshhold = cv2.inRange(img, cv2.cv.Scalar(3,3,125), cv2.cv.Scalar(40,40,255))
cv2.imshow('threshholded', imgthreshhold)
k = cv2.waitKey(10)
if k==27:
break
cap.release()
cv2.destroyAllWindows()
我怎样才能解决这个问题？
最佳答案
我一直面临着同样的问题。而且我认为我们正在遵循OpenCV的同一教程。我稍微弄乱了这个函数，发现只提供值就可以了。
因此，您的代码应如下所示:
import cv2
cap = cv2.VideoCapture(0)
#help(cv2)
while cap.isOpened():
#BGR image feed from camera
ret, img = cap.read()
cv2.imshow('output', img)
#BGR to grayscale
img2 = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
cv2.imshow('grayscale', img2)
#BGR to binary(RED) thershholded
imgthreshhold = cv2.inRange(img, (3,3,125), (40,40,255))
cv2.imshow('threshholded', imgthreshhold)
k = cv2.waitKey(10)
if k==27:
break
cap.release()
cv2.destroyAllWindows()
关于python - AttributeError: 'module'对象没有属性 'cv'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38934374/
