Overview


Elphel Eyesis4Pi is a 64 Mpx panoramic camera covering 360*180 (4Pi) view angle.^" The camera is designed to be a measurement tool for photogrammetry and for future 3D reconstructionof the scenes due to precise optical calibration of sensor+lens modules and pixel-mapping. Eyesis4Pi can be mounted on a car for outdoor panoramic applications and also lightweight enough to be carried by a person, which allows to successfully create panoramas of small and narrow spaces.^*

^{* There are simplified modification of the camera available (see "Camera Models" below).}

Elphel Eyesis4π models

Eyesis4Pi:

There are 24 x 5MPix sensors in the camera head plus 2*5MPix sensors positioned in the camera pole. The total resolution is 64 Mpix after stitching images into panorama.

Eyesis4Pi Modifications:

Eyesis4Pi-16: 360*120’ panoramic camera with 16 image sensors (not covering nadir);

Eyesis4Pi-24: 360*180’ panoramic camera with 24 image sensors without 2 sensors in the pole sensors;

Other modifications are possible upon reques.

All the models include:

The Inertial Measurement Unit - IMU ( ADIS 16375, 2400 samples per second) is integrated with the camera, as well as 5Hz GPS. IMU provides precise position and orientation of the camera. Images are synchronized with the IMU and GPS data.

Images are recorded to internal Solid State Drives (SSD) or to an external computer over the network. Eyesis4Pi camera system includes Eyesis computer for image downloading and post-processing with pre-installed SDK and Free and Open Source Software for camera calibration, image acquisition and panorama stitching.

Panorama Image Samples are available on wiki: http://wiki.elphel.com/index.php?title=Eyesis4Pi_samples

There are several ways to view panoramas made Eyesis4Pi: WebGL viewer: spherical view, which can be rotated around you as an observer. (This viewer requires a browser supporting WebGL like Firefox4 or Chrome). Equarectangular projection of spherical panorama (link to wikipedia): Jpeg image made for WebGL viewer. Screenshot images of panorama in WebGL viewer.

Camera Parameters:

Sensor Front Ends: 24 High Resolution Sensor Front Ends:

	5 MPix  sensor (Aptina MT9P006),

Lenses (),

adjusted to reduce aberration.  Compact Optical Layout achieves lesser parallax. 

Data Storage: internal: 8 x 256 Gb SSDs (Solid State Drives); external: over the Network.

Position and Orientation Measurement: Inertial Measurement Unit (IMU) - ADIS 16375: 2560 recorded measurements per second. GPS receiver (Locosys LS20031): 5-10 Hz update rate. Odometer / Pedometer Input Interface Images are synchronized with IMU and GPS with 1Mu/s resolution GPS powered geo-tagging

Physical Characteristics: Weight 10 Kg; Size 230 x 1350 mm; Power Consumption – 50W; Weatherproof.

Image Capturing Recording Speed: 2.5 FPS (Frames per Second) recommended for final panorama image quality; 5 FPS maximum recording speed.

Recording Time: 11 hours at 2.5 FPS, to internal storage.

Recording Image Format: JP4 (RAW format), recommended; JPEG.

Recording Controls: Web based Graphical User Interface (GUI).

Camera Software:

Camera Internal Software (Firmware): SDK for internal camera software customization: shared with 10353E system board SDK;

Host computer software: Eyesis GUI for recording: Post-Processing Tools for creating panoramas:

All software is FOSS (Free and Open Source Software). It is experimental software that used to test the camera performance, and it continues to be developed. All updates are available for download from git repository at SorceForge. Software may require integration with customer software depending upon camera hardware configuration and application.

Camera Operation Workflow (table with minuts) (example: 100 panoramas = 50 hours ):

Starting the camera: Turn on PoE Switch

Run system tests: Setup parameters for recording: define data storage paths; select shooting settings: FPS, whiteballance, autoexposure parameters, mode Start Recording Stop Recording
