Gaia, One Billion $ One Billion Pixels 3D Camera

on Thursday, 19 December 2013 12:50. Posted in Research Projects

The European Space Agency (ESA) is sending the $1.2 billion Gaia mission to space to catalog a billion galaxies, stars, and planets in the next five years. The super resolution map of the sky will thus cost on dollar per star... With one billion pixels, the camera designed by Astrium is the largest digital camera ever built for a space mission.

The dual telescope will orbit around the L2 Lagrange point (which is located 1.5 million km from the Earth in the anti-Sun direction) and will scan the sky continuously with is super-huge CCD camera for five years. The main sensor is a mosaic of 106 credit-card size CCD devices (4500x1600 pixels each) with a total area around 0.5 x 1-meter (1.6 x 3.3-foot).

3D Theatrical Manoeuvres in the Dark

on Sunday, 08 December 2013 19:32. Posted in Research Projects

A super-sensitive camera is developed by Ahmed Kirmani at MIT labs that may one day change the way we shoot pictures in 3D. The new camera records photons from the scene one by one, meaning it can see in almost complete darkness. The new system is 100 times more sensitive than state-of-the-art LIDARs.

The new process uses existing photon-detector technology, but applies a new algorithm to extract the maximum possible information from each reading and assemble that info into a 3D model of the surroundings.

Fourth Report on Stereoscopic Film Quality Released

on Sunday, 03 November 2013 17:21. Posted in Research Projects

Researcher Denis Sumin and his supervisor Pr. Dmitriy Vatolin from Lomonosov Moscow State University in Russia are leading a project on 3D stereoscopic movie quality assessment called VQMT3D (Video Quality Measurement Tool 3D).

The Lab decided to analyze several stereoscopic films and to investigate the potential reasons of headache and eyestrain often suffered by some moviegoers. The first two reports were focused on films captured with stereoscopic camera systems, and the main problems discovered during the film analysis were: excessive horizontal disparity, vertical disparity, color mismatch, and sharpness mismatch.

Report #4 of 6 has just been released on October 1st, 2013 (free access to all 3D professionals -see links here under). It covers excessive horizontal disparity, vertical disparity, color mismatch, and sharpness mismatch.

This incredibly acurate report contains a full frame-by-frame analysis with charts showing metric values. Here under you can see an example of vertical disparity from "Step Up Revolution".

MIT 3D Detection Camera is Able to See Transparent Objects

on Wednesday, 27 November 2013 22:17. Posted in Research Projects

Three MIT students developed a 3D camera that could be used in medical imaging and collision-avoidance detectors for cars, and to improve the accuracy of motion tracking and gesture-recognition devices used in interactive gaming. Compared with Microsoft's Kinect the new device is a clear winner -at least outdoors- as it is not fooled by rain, fog, or even windows and translucent objects.

The camera was presented last week at Siggraph Asia in Hong Kong.

3D Tongue-in-Cheek

on Sunday, 13 October 2013 10:30. Posted in Research Projects

The Seeing Speech project was funded by the Carnegie Trust and involved researchers from Glasgow, Queen Margaret, Strathclyde, Edinburgh and Aberdeen universities (all in Scotland, UK).

Three dimensional videos which show how tongues move during speech feature on the freshly published website, designed to help teachers, scientists, health experts and actors. The Seeing Speech website, created by a University of Glasgow-led team, includes tongue and vocal tract videos using ultrasound and MRI technology. The clips show the tongue's movement at full and half speed to allow for study.

Images recording is done by a combination of ultrasound imaging and MRI (magnetic resonance imaging).
