python - cv2 videoCapture 没有属性

Question

import cv2

import sys


cpt=0

vidStream=cv2.videoCapture(0)
while True:
    ret,frame=vidStream.read()

    cv2.imshow("test frame",frame)
    cv2.imwrite(r"C:\Users\Abhishek\PycharmProjects\images\0\image%04i.jpg"%cpt,frame)
    cpt +=1

    if cv2.waitKey(10)==ord('q'):
        break

任何人请帮我修复错误
我收到一条错误消息，上面写着“模块 'cv2.cv2' 没有属性 'videoCapture'”和“无法导入 cv2”

Answer 1

1) 不是 cv2.videoCapture()，而是尝试 cv2.VideoCapture()。

Python 2.7.18rc1 (default, Apr  7 2020, 12:05:55) 
[GCC 9.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> vid = cv2.videoCapture(0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'videoCapture'
>>> vid = cv2.VideoCapture(0) #like that it works fine.
>>> 

尝试安装 opencv 使用命令 pip install opencv-python或 pip install opencv-contrib-python ，并检查您是否仍然收到“无法导入 cv2”错误
