Raspberry pi camera

Description: 

The Camera Module is a custom designed add-on for Raspberry Pi. It attaches to Raspberry Pi by way of one of the two small sockets on the board upper surface. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data.

The board itself is tiny, at around 36mm x 36mm highlight of our module is that the Lens is replaceable compared to official one, making it perfect for mobile or other applications where size and image quality are important. It connects to Raspberry Pi by way of a short ribbon cable. The camera is connected to the BCM2835 processor on the Pi via the CSI bus, a higher bandwidth link which carries pixel data from the camera back to the processor. This bus travels along the ribbon cable that attaches the camera board to the Pi.

The sensor itself has a native resolution of 5 megapixel, and has a fixed focus lens onboard. In terms of still images, the camera is capable of 2592 x 1944 pixel static images, and also supports 1080p30, 720p60 and 640x480p60/90 video.

The camera is supported in the latest version of Raspbian, Raspberry Pi's preferred operating system.

  • Raspberry Pi HD Camera
  • High-Definition video camera for Raspberry Pi Model A or B.
  • Omnivision 5647 sensor in a fixed-focus module with replaceable Lense

  • Connection by flat ribbon cable to 15-pin MIPI Camera Serial Interface (CSI) connector S5 on Raspberry Pi computer board
  • The Camera Lens for Raspberry Pi Camera Board is LS-40136

How to use the Raspberry Pi camera software

raspivid is a command line application that allows you to capture video with the camera module, while the applicationraspistill allows you to capture images.

-o or –output specifies the output filename and -t or –timeout specifies the amount of time that the preview will be displayed in milliseconds. Note that this set to 5s by default and that raspistill will capture the final frame of the preview period.

-d or –demo runs the demo mode that will cycle through the various image effects that are available.

Example commands

Capture an image in jpeg format:

#raspistill -o image.jpg

Capture a 5s video in h264 format:

#raspivid -o video.h264

Capture a 10s video:

#raspivid -o video.h264 -t 10000

Capture a 10s video in demo mode:

#raspivid -o video.h264 -t 10000 -d

To see a list of possible options for running raspivid or raspistill, you can run:

#raspivid | less

#raspistill | less

Use the arrow keys to scroll and type q to exit.

Extended documentation is available.

Note that we recommend that you change SSH password if you are using a camera, in order to prevent unwanted access.

How to stream video from the Raspberry Pi camera over a network

To view the feed on Linux

Install the dependencies by running the following in a terminal:

sudo apt-get install mplayer netcat

Find your IP address by running ifconfig. (Your IP address will be listed in the console output and will probably be of the form 192.168.1.XXX).

Run the following command in a terminal to view the feed using MPlayer:

#nc -l -p 5001 | mplayer -fps 31 -cache 1024 -

To view the feed on Windows

Install and run Linux instead.

Find your IP address by running ipconfig. (Your IP address will be listed in the console output and will probably be of the form 192.168.1.XXX).

Download MPlayer & Netcat.( netcat is a tool which allows sending data over the network, its used to send the video from raspberry pi to the computer )

Note that your browser may complain that these files are malicious, as they are unsigned executables.

Press the Windows key and the ‘r’ key simultaneously to bring up the “Run” dialog. Enter cmd.exe into the dialog and press enter/return to open a DOS prompt.

Enter the following command at the prompt to view the feed using MPlayer:

[Path to nc.exe]\nc.exe -L -p 5001 | [Path to mplayer.exe]\mplayer.exe -fps 31 -cache 1024 -

To view the feed on OS X

Download MPlayer.

Alternatively, you can download mplayer using Brew, which we recommend.

Find your IP address by running ifconfig. (Your IP address will be listed in the console output and will probably be of the form 192.168.1.XXX).

Run the following command in Terminal to view the feed using MPlayer:

#nc -l -p 5001 | mplayer -fps 31 -cache 1024 -

To view the feed on a Raspberry Pi:

Find your IP address by running ifconfig. (Your IP address will be listed in the console output and will probably be of the form 192.168.1.XXX).

Run the following commands in a terminal on the receiving Pi:

mkfifo buffer

#nc -p 5001 -l > buffer | /opt/vc/src/hello_pi/hello_video/hello_video.bin buffer

To transmit the feed from the Pi with camera module attached

After setting up the “receiving” machine as per the instructions above, run the following commands in a terminal on the “transmitting” Pi:

#raspivid -t 999999 -o – | nc [insert the IP address of the client] 5001

You can then use the commands listed in the “How to use the Raspberry Pi camera software” section above to change the capture time or to add a video effect.
