StereoPi
The best solution for experiments with 3D video
with Raspberry Pi inside!

Paradise for coders
Did you know that stereo natively supported in Raspbian from 2014?
Capture still image...

...or capture a video




Use OpenCV for computer vision
 




Process it with Python or C++
  • raspistill utility in Raspbian natively supports stereo mode. To capture this image we used:
    raspistill -3d sbs -w 1280 -h 480 -o 1.jpg
     
  • raspivid, used for video capture in Raspbian, also support stereo out of the box.
    raspivid -3d sbs -w 1280 -h 480 -o 1.h264
     
  • Like Python? Picamera supports stereo, for capturing stereo you may just use:
    camera = PiCamera(stereo_mode='side-by-side', resolution=(1280,720))
     camera.capture('foo.jpg')

     
  • C/C++? Picamera library also did this work for you
     
  • OpenCV for camera undistortion, stereo image calibration and depth map
     
  • You can find stereo mode implementation history on Raspberry Pi forum thread
ROS support out of the box

We used ROS Kinetic from Ubiquiti Robotics to obtain depth map. This Ubuntu-based image has the same kernel as Raspbian, so stereoscopic mode is natively supported. You can find current implementation discussion here on GitHub
You can also read full ROS experiments story in our Blog on Medium.
Livestream video to YouTube

We did 3D printed case, inserted LTE modem and wrote a simple script for RTMP livestream. You can look at original not edited livestream record of this test here on YouTube. We plan to make one more test with sound (adding USB microphone).
3rd person view with Oculus Go

Just a fun experiment with StereoPi and Oculus Go: "3rd person view in a real life". 3D printed case, camera back-support, Android application for Oculus Go and simple code on StereoPi took several days.
You can find out more details about this project here in our blog on Medium
3D FPV for RC geeks

If you like DIY-style FPV like WiFi-broadcast you need just run it on StereoPi and add -3d sbs parameters to your script.
Also we used -dec option to compress both images width to save original FOV of our 160 degree cameras.

If you like ready-to-go FPV video links able to capture video from HDMI sources you can use it with StereoPi. For example you can connect HDMI out from StereoPi to input of Insight SE 5G or any other video link.

You can also use two independent livestreams from both cameras, like "front view" and "rear view".
360 panoramic photo and video

Post from RICOH THETA. - Spherical Image - RICOH THETA

You may mention most of modern 360 degree cameras use two wide-angle cameras. You can make such experiments with StereoPi!
We added two 200-degree cameras to StereoPi, installed device on tripod and captured couple of photos. Then we googled "spherical panorama", have found "Ricoh Theta software", downloaded trial and in a 10 minutes have our first 360 spherical panorama!
Here is a steb-by-step guide in our blog to repeat this experiment.
Raspberry Pi inside!
StereoPi carrier board supports all Raspberry Pi Compute modules
 


Raspberry Pi Compute Module 3 Lite


Raspberry Pi Compute Module 3


Raspberry Pi Compute Module 1
(power mode switchable)
Raspbian out of the box

Just download the latest Raspbian image, write it on MicroSD card – and here you go!
If you already worked with Raspberry Pi and have MicroSD with your project – just put it in StereoPi and continue with stereo!
Need stereo for old projects? Just enable second camera by putting dtblob.bin in boot partition.
Classic Raspberry Pi GPIO header


Use your Pi with external hardware?
We kept all classic Pi GPIOS for you to be able continue your projects!
Thermometers, servos, relays and other goodies for your fun!
