Capture webcam with Python (OpenCV): step by step
This is a part of Python for Image and Video Processing with OpenCV.
In this Python video tutorial I demonstrate how to capture webcam video with Python. Streaming webcam video in real time in Python is very simple processing, just follow the steps I demonstrating on video tutorial.
For this example I used Lifecam VX-1000 and Python 3.5.2.
This method is suitable for any type of external computer camera or laptop camera.
The content of the video tutorial is:
1. Demonstration of video capturing by Python: 0:02
2. Starting coding: 0:29
#0 Import Python modules: cv2, time: 0:31
#1 Create a video object: 0:38
#2 Define Shutdown for camera 1:05
#3 Create a Frame object 1:42
#4 Show the Camera frame on the screen 2:39
#5 Set that any Key (from keyboard) will break the video capturing 3:20
#6 Converting video frame to Grayscale 4:16
#7. THE MOST IMPORTANT MOMENT: make video capturing frames a whole stream 5:18
For make video capturing in frequency to 1 millisecond (every frame is refreshes every 1 millisecond) I use While loop in Python. For testing purposes you can change refreshing interval.
P.S. set Q key for break a capturing: 6:13
Demonstration result of video capturing by Python and break it by press Q key: 7:30.
I hope this video tutorial will be good for python beginners and give you a basic understand how to programming and coding any computer camera.
