StereoPi - companion computer on Raspberry Pi with stereo video support
https://diydrones.com/profiles/blogs/stereopi-companion-computer-on-raspberry-pi-with-stereo-video-1

 Compute Module 3 for playing with stereo video and OpenCV. It could be interesting for those who study computer vision or make drones and robots (3D FPV).

It works with a stock Raspbian, you only need to put a dtblob.bin file to a boot partition for enabling second camera. It means you can use raspivid, raspistill and other traditional tools for work with pictures and video.

JFYI stereo mode supported in Raspbian from 2014, you can read implementation story on Raspberry forum.

Before diving into the technical details let me show you some real work examples.

1. Capture image:

raspistill -3d sbs -w 1280 -h 480 -o 1.jpg

and you get this:

You can download original file here.

2. Capture video:

raspivid -3d sbs -w 1280 -h 480 -o 1.h264

and you get this:

You can download original captured video fragment (converted to mp4) here.

3. Using Python and OpenCV you can experiment with depth map:

For this example I used slightly modified code from my previous project 3Dberry (https://github.com/realizator/3dberry-turorial)

I used this pair of cameras for taking the pictures in examples above:
