Pi Camera Quick Installation Guide
Setup your Raspberry Pi Camera fast with our with our quick tutorial, and then learn the basics of using it
One of the most recent Raspberry Pi accessories is the tiny Pi Camera board – a small PCB with a camera sensor mounted to it that connects to the Pi. It connects directly to the Raspberry Pi board to save USB slots, however this does not make it exactly plug and play, so you’ll need to do some extra set-up on your Raspberry Pi to get it to work.
The Pi Camera has multiple use cases, such as timelapse photography, using as a webcam or even as an optical sensor for a Pi-powered robot. As it doesn’t take up any USB ports and draws very low power, it can be a lot more versatile than a standard webcam.
The Pi Camera itself is not a low quality piece of kit either – with a 5MP sensor, it’s also able to create up to 1080p quality video, the same as the Raspberry Pi’s HDMI output. Grab your Raspbian SD card, and get started making the most out of your Pi Camera.
Step by Step
To attach the camera to the Raspberry Pi, locate the slot between the Ethernet and HDMI port, and gently lift up the fastener. Insert the ribbon of the camera board, making sure to align the ribbon’s connectors with those on the Raspberry Pi.
Before we try and enable the Raspberry Pi camera, make sure your firmware and software are all up-to-date with a quick software upgrade. In Raspbian, we do this by opening the terminal and using:
$ sudo apt-get update
$ sudo apt-get upgrade
Once that’s finished, run in the terminal or command line:
$ sudo raspi-config
…to start the standard configuration screen. Navigate down to Enable Camera, press Enter, and then simply key over to enable and confirm with another press of Enter. Select Finish, and reboot.
To take pictures with the Raspberry Pi Camera, you’ll simply need to enter:
$ raspistill -o image.png
This will show a five second preview of the input of the camera, and then capture the last frame of the video
To record a video, we use a similar command, raspivid, like so:
$ raspivid -o video.h264
Similar to the image taking,
If you want to do a little more with the Pi Camera, there’s a simple python wrapper currently available called picam. You’ll need to install it first though, and we’ll use pip for that. Install pip with:
$ sudo apt-get install python-pip
…and then enter:
pip install https://github.com/ashtons/picam/zipball/master#egg=picam
We can now use Python to construct a script to take photos with the picam module. Very simply, all you need to do is enter:
import picam i = picam.takePhoto() i.save('/home/pi/test.jpg')
And running it will take photo, test.
You can have it take photos of specific size and quality with a time-based name by editing the code to look like this:
import picam import time ii = picam.takePhotoWithDetails(640,480, 85) filename = "/tmp/picam-%s.jpg" % time.strftime("%Y%m%d-%H%M%S") ii.save(filename)
Picam Video and More
Picam also allows you to take video in a similar way to the above, with the main difference being that you’ll use recordVideo. You can use the code to take photos or video at regular interval for timelapse, or have it trigger during a specified event
