ABSTRACT

Raspberry Pi has mostly used hardware to interface/working with the camera-based application. Mainly for Open CV (Open Computer Vision) based applications. As the Raspberry Pi beginner first to learn about to capture the image using Raspberry Pi with a USB camera. If the image is captured using below code, the captured image is stored in the current directory.

HARDWARE REQUIRED

• Raspberry Pi
• SD card
• Power supply
• VGA to HDMI converter (Optional)
• USB camera

SOFTWARE REQUIRED

• Raspbian Stretch OS      
• SD card Formatter
• Win32DiskImager (or) Etcher

PYTHON LIBRARIES USED

• Fswebcam library to capture the image
• Subprocess to do the parallel process for capturing the image while the code is running
• Open CV (CV2) (Optional) 

CODE

import subprocess
subprocess.Popen("sudo fswebcam image.jpg",shell=True).communicate()
