Superseded by Elphel_Eyesis4Pi
Elphel Eyesis is an open hardware / free software panoramic camera solution that is able to capture high-resolution - 38 MPix total (45 MPix before stitching) - 360° panoramas at a rate up to 5 frames per second at full resolution. Images are recorded to 3 swappable solid-state-discs (Eyesis Data Storage) which can store up to 11 hours of footage at full resolution. Meta-data like GPS-coordinates (geotags), viewing direction, movement speed, etc. are directly embedded into the images EXIF fields. Eyesis uses 9 sensor-front-ends and high-grade lenses that are triggered simultaneously with microsecond accuracy.
The camera head was designed to be small and lightweight with a minimal distance between the entrance pupils (29.5 mm) to achieve lowest possible parallax.
The primary usage scenario is to mount Eyesis on the roof of a vehicle. When driving at 50 mph (22.3 m/s) and recording at 5 FPS a full panorama is captured every 4.46 meters.
Though the total weight is just around 10 kg (22 lbs.) which also allows back-pack like operation.
Operation & Monitoring
Eyesis is controlled from a laptop, via a web-based interface (Eyesis GUI). Which also displays real-time previews of your captured panorama footage.
Eyesis is supplied with 110V/220V AC and can be used with car power adapter (inverter), when mounted on a car roof. Power consumption is around 50W.
The sensor-front-ends - which were especially developed for Eyesis - allow the focus plane to be shifted and rotated with very high accuracy. This allows extremely precise calibration of each lens and SFE which is done with every Eyesis during assembly with custom developed software.

Why are there 3 SSDs and not just a single bigger one?
There are nine sensor-front-ends. There are 3 system boards each connected to 3 sensor-front-ends and one SSD. So the shots of a single panorama are split up one 3 SSDs. 3 images to SSD1, 3 images to SSD2 and 3 images to SSD3.
Can I also use the Eyesis Data Storage with HDDs instead of SSDs?
We initially tested the system with HDDs but due to strong vibrations when using Eyesis mounted to a car roof we experience massive write-rate drops with HDDs. After we switched to SSDs all these problems were gone. If your Eyesis application does not involve bumby roads or vibrations HDDs should work just fine though.
What software do I need on my laptop/computer to control Eyesis?
Eyesis GUI requires a locally running webserver (apache2 + PHP5) and the Eyesis GUI software.
Install Instructions provide packages for Ubuntu and instructions for installation on other operating systems.
How do I connect my laptop/computer to Eyesis and how do I control image recording?
The Eyesis Data Storage Box hosts a Gigabit Ethernet switch so all you need is one Ethernet cable from the Data Storage Box to your laptop/computer.
The Eyesis GUI is completely browser based so after you connected to the network you just start a browser type in the correct URL and you are ready to go.
