Image georegistration method and system. An imaging sensor acquires a sensor-image of a scene. Imaging parameters of the acquired sensor-image are obtained, the imaging parameters including at least the detected 3D position and orientation of the imaging sensor when acquiring the sensor-image, as detected using a location measurement unit. A model-image of the scene is generated from a textured 3D geographic model, the model-image representing a texture-based 2D image of the scene as acquired in the 3D model using the imaging parameters. The sensor-image and the model-image are compared and the discrepancies between them determined. An updated 3D position and orientation of the imaging sensor is determined in accordance with the discrepancies. The updated position and orientation may be used to display supplementary content overlaid on the sensor-image in relation to a selected location on the sensor-image, or for determining the geographic location coordinates of a scene element.

A photodetector-array and a method for fabricating the same are disclosed. The photodetector-array includes: a first semiconductor structure having an active region including plurality of active photodetectors defining light sensitive regions; and a second semiconductor structure defining a plurality of active readout integrated circuit pixels (RICPs) having electric contacts electronically connectable to electric contacts of respective active photodetectors of the first semiconductor structure, for carrying out respective read out operations from the active photodetectors.

The present invention discloses a photo-detector comprising: an n-type photon absorbing layer of a first energy bandgap; a middle barrier layer, an intermediate layer is a semiconductor structure; and a contact layer of a third energy bandgap, wherein the layer materials are selected such that the first energy bandgap of the photon absorbing layer is narrower than that of said middle barrier layer; wherein the material composition and thickness of said intermediate layer are selected such that the valence band of the intermediate layer lies above the valence band in the barrier layer to create an efficient trapping and transfer of minority carriers from the barrier layer to the contact layer such that a tunnel current through the barrier layer from the contact layer to the photon absorbing layer is less than a dark current in the photo-detector and the dark current from the photon-absorbing layer to said middle barrier layer is essentially diffusion limited and is due to the unimpeded flow of minority carriers, thus reducing generation-recombination (GR) noise of the photo-detector. The principles of the present invention also apply to inverted polarity structures of the form pBp in which all the doping polarities and band alignments described above are reversed.

Agency: European Commission | Branch: H2020 | Program: CS2-IA | Phase: JTI-CS2-2015-CFP02-LPA-03-06 | Award Amount: 1.30M | Year: 2016

The ANGI-HUD (Advanced Next Generation Intelligent Head Up Display) proposal responds to the 2nd Call for Proposals of the Clean Sky 2 Joint Undertaking under the topic JTI-CS2-2015-CFP02-LPA-03-06 Head Up System integration in next generation cockpits. The consortium can meet the technical challenges. Within IADP LPA Platform 3 (Next Generation Aircraft Systems, Cockpit and Avionics) a number of new and advanced functions are developed and demonstrated that will be considered and elaborated on in the ANGI-HUD project. Specifically, the ANGI-HUD activities will line up with the work performed under WP3 of the Clean Sky 2 Joint Undertaking. The main objective of the ANGI-HUD project is to analyse how the capacities of the Head Up Display could be used to provide new functionalities, in combination with other visualization means, and to demonstrate them on a fixed-based simulator. The ANGI-HUD project will contribute to the analysis of potential new functionalities, prototype the intended new Man Machine Interface, provide the Airframer with two representative Head Up Systems, including rapid prototyping capacities, and participate to, and support, bench tests at the Airframers simulation facilities. A rather novel and ambitious aspect will be the development of the so-called eyes- out cockpit concept; i.e. the capability to perform approaches and landings only using the information displayed on the ANGI-HUD and via HUD-integrated eye tracking technology. The comprehensive experience of the partners in the areas of head up systems, head up symbology design, flight simulation, cockpit design, human factors evaluations, as well as experience in simulator and flight testing of airliners and business jet flight operations motivated the common application to this call. The specific skills and know-how of each partner and their complementarity are crucial for demonstrating a higher TRL for the technologies considered here.
