MULTISPECTRAL ENHANCED VISION SYSTEM AND METHOD FOR AIRCRAFT LANDING IN INCLEMENT WEATHER CONDITIONS
Publication number: 20190035290Abstract: Apparatus for detecting airfield light emitters, the apparatus including a plurality of light detection cameras, each detecting at least one respective waveband of electromagnetic radiation within the electromagnetic spectrum, each of the light detection cameras producing a plurality of respective spectral images, and a processor coupled with the light detection cameras, thereby generating a multispectral image of the airfield light emitters from the spectral images, the multispectral image including a multi-dimensional set of spectral values, wherein the processor further determines which combination the multi-dimensional set of spectral values corresponds with a plurality of distinct light emission characteristics of the airfield light emitters by identifying a particular spectral signature corresponding to the multi-dimensional set of spectral values, wherein the processor produces an enhanced image from those spectral values of the multi-dimensional set of spectral values which correspond to the determineType: ApplicationFiled: January 25, 2018Publication date: January 31, 2019Inventors: Ron Schneider, Ofer David, Dror Yahav -
Patent number: 8885177Abstract: A medical Wide-Field-Of-View optical-tracking-system for determining the position and orientation of a target-object in a reference coordinate system. The system includes at least three light-emitters, at least one optical-detector and a processor. The processor is coupled with each optical-detector. One optical-detector is a Wide-Field-Of-View optical detector, which acquires an image of the light-emitters within the field-of-view thereof. Each Wide-Field-Of-View optical-detector includes an optical-sensor and two optical-receptors. The processor determines the position and orientation of the target-object in the reference coordinate system according to representations of the light-emitters. Each light-emitter is within the field-of-view of an optical-detector. Each optical-detector and each light-emitter is attached to one of the target-object and a reference-location.Type: GrantFiled: November 21, 2013Date of Patent: November 11, 2014Assignee: Elbit Systems Ltd.Inventors: Rani Ben-Yishai, Adi Charny, Dror Yahav, Shahaf Zommer, Ilan Efrat

Patent number: 8687056Abstract: Enhanced vision system for assisting aircraft piloting, the system including a line-of-sight detector for determining the line-of-sight of the pilot of the aircraft, a head mounted display (HMD) worn by the pilot, and a processor which receives the determined line-of-sight from the line-of-sight detector, receives a spatial image of the external scene to the aircraft, generates symbolic information respective of the aircraft piloting, and superimposes the symbolic information onto the spatial image to produce a combined spatial and symbolic image, the HMD displaying the combined spatial and symbolic image to the pilot in real-time, in alignment with the determined line-of-sight. The spatial image may be an image combined from a sensor image and a synthetic image. A communication interface may be coupled to the HMD allowing the pilot to receive and confirm flight instructions.Type: GrantFiled: July 15, 2008Date of Patent: April 1, 2014Assignee: Elbit Systems Ltd.Inventors: Dror Yahav, Yaron Kranz, Asaf Ashkenazi, Itai Orenstein, Tal Waisman, Mike Abrahami

Patent number: 8593647Abstract: An optical tracking system for determining the pose of a moving object in a reference coordinate system includes light emitters, optical detectors, and a pose processor. The processor is coupled with an optical detector and also with a light emitter. The processor determines the object's pose according to detected light. An optical detector and a light emitter are situated at a fixed position in the reference coordinate system. Other ones of the optical detectors and light emitters are attached to the object. One optical detector is a WFOV detector comprising an optical sensor and optical receptors. The receptors are spaced apart and optically coupled with the optical sensor. The sensor senses light received from a light emitter. Each receptor projects a different angular section of a scene on the sensor. The pose processor associates the representation on the sensor, with a respective receptor which projected the light on the sensor.Type: GrantFiled: January 22, 2013Date of Patent: November 26, 2013Assignee: Elbit Systems Ltd.Inventors: Adi Charny, Dror Yahav, Shahaf Zommer, Ilan Efrat, Rani Ben-Yishai
