Elphel Eyesis4Pi is an open hardware / free software panoramic camera solution that is able to capture high-resolution - 64 MPix total (120 MPix before stitching) - 360° panoramas at a rate up to 5 frames per second at full resolution. It is the successor of the Elphel Eyesis. Images are recorded to 8 solid-state-discs (Eyesis4Pi 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. Eyesis4Pi uses 24 sensor-front-ends and high-grade lenses that are triggered simultaneously with microsecond accuracy to ensure a full homogeneous spherical snapshot.

Usage Scenarios

The system was designed to be small and lightweight with a minimal distance between the entrance pupils (46.5mm) to achieve lowest possible parallax.

The primary usage scenario is to mount Eyesis4Pi 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.

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 ???W.

Models

4π (or 4Pi) corresponds to a full full spherical (360°x180°) field of view in steradians.

There are 2 version of the camera Eyesis4Pi with 24 image sensors and full spherical field of view and Eyesis3Pi with 16 sensors (without 8 bottom modules) with slightly smaller field of view.

Notes:

  1. Angular resolution per pixel differs in the sub-camera FOV, minimal resolution is used.
  2. Zenith area for Eyesis (covered by fisheye lens) is calculated separately.
  3. For Eyesis the distance is measured from the entrance pupil of the horizontal lens to that of the top fisheye, for Eysis-4pi – to the entrance pupil of the lens immediately above/below the first one.
  4. Frame rate may be limited by the recording (or network if the SSD are not used) datarate for high compression quality (>0.3 bytes/pixel), required for the aberration correction.


Calibration

The sensor-front-ends (SFE) - which were especially developed for Eyesis4Pi - 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 Eyesis4Pi during assembly with custom developed software. Check out this Elphel Development Blog post for more details.

Eyesis4Pi-393 is the newest generation of the full-sphere multi-camera systems for stereophotogrammetric applications.
  • The system is calibrated to compensate for optical aberrations allowing to preserve full sensor resolution over the field of view.
  • Distortion calibration is performed for precise pixel-mapping to automatically stitch images into panoramas, and also for photogrammetry and 3D reconstruction.  
  • There are 24 x 5MPix sensors in the camera head, resulting in 120 MPix image acquisition. Panorama image resolution after stitching is 64 MPix, the equirectangular projection is 14000x7000.
  • High-precision Inertial Measurement Unit IMU (ADIS 16375, 2400 samples per second) is integrated with the camera, as well as 5Hz GPS (Locosys LS20031) to provide precise position and orientation of the camera.
  • Images, synchronized with IMU and GPS data, can be recorded to internal Solid State Drives (SSD), external swappable SSDs or to a PC over the network.
  • Optionally Eyesis4Pi-393 camera system includes PC for image downloading and post-processing with pre-installed SDK and Free and Open Source Software for camera calibration, image acquisition and panorama stitching.
  • Eyesis4Pi-393 can be mounted on a car for outdoor panoramic applications or carried by a person, which lets successfully create panoramas of small and narrow spaces.*

Automated panoramic imagery and 3-dimensional panoramas are the 2 main applications of Eyesise4Pi-393 camera.
