Overview
Elphel Eyesis4Pi-26-393 is the newer generation of the full-sphere multi-camera systems for stereophotogrammetric applications.
Automated panoramic imagery and 3-dimensional panoramas are the 2 main applications of Eyesise4Pi-393 camera. Improvements over older generation Eyesis4Pi

Calibration
We have developed full calibration process and post-processing software to compensate for optical aberrations, allowing to preserve full sensor resolution over the camera FOV, and distortions – for precise pixel-mapping for photogrammetry and 3D reconstruction. Check out this Elphel Development Blog post for more details.
