如何在Python中使用网络摄像头捕获图像？

Question

There are certain libraries such as fswebcam, cv2 etc. But pip cant find a matching distribution for Python3 on Win7 64bit. Are there any other libraries or how can i use these two to capture images from Python

Answer 1

I installed openCV on my 64-bit windows 10 machine using openCV and numpy wheels, which I installed using pip.

You can find the numpy wheels here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

And the cv2 wheels here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv

Make sure you find the wheels specific to your setup, ie. 64-bit with python 3.6, use: numpy‑1.14.5+mkl‑cp36‑cp36m‑win_amd64.whl

Save those in a folder, then navigate to that folder in a command window and install the files using pip.

Answer 2

I guess the reason is that you have both Python2 and Python3 installed, and therefore pip only works for Python 2. You can install OpenCV as follows:

python3 -m pip install opencv-python

You have to make sure Python 3 has been added to the system path and the command Python3 is available. If the executable file of Python 3 is named Python , just rename it to Python3 .
