How to Connect to the Default Webcam of Your Computer in Python using OpenCV



Python


In this article, we show how to connect to the default webcam of your computer in Python using the OpenCV module.

OpenCV allow us to perform a number of different image and video manipulations.

Using OpenCV, we can connect to the default webcam of our computer and then once connected, we can later do things such as open up the webcam and record and save video.

In this articles, though, we're simply going to show how to connect to the default webcam.

In later articles, we will then show how to open up the webcam and then record video.

So in order to connect to the default webcam of your computer, we use the following code shown below.



Let's now go over this code.

First, we import the cv2 module.

Next, we create a variable, video. We assign this variable to, cv2.VideoCapture(0).

The VideoCapture() function allows us to connect to a device such as a webcam on our computer. When 0 is placed in as the parameter to VideoCapture(), this connects to the default webcam of our computer.

When we now run the video variable, we see that it has successfully connected to our default webcam.

Now that we're now connected to a webcam on our computer, we can now do things such as open up the webcam and record video.

And this is how to connect to the default webcam of your computer in Python using the OpenCV module.
