About
Elphel Eyesis is a complete 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.
Usage Scenarios
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 can be supplied with 110V/220V AC and can be used with car power adapter, when mounted on a car. Power consumption is around 50W.
Calibration
The sensor-front-ends (SFE) - which were especially developed for Eyesis - allow the focus plane to be shifted and rotated in all 3 dimensions. This allows extremely precise calibration of each lens and SFE which is done with every Eyesis during assembly with custom developed software.

FAQ
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.
