Publication number: 20240169658Abstract: A stored volumetric scene model of a real scene is generated from data defining digital images of a light field in a real scene containing different types of media. The digital images have been formed by a camera from opposingly directed poses and each digital image contains image data elements defined by stored data representing light field flux received by light sensing detectors in the camera. The digital images are processed by a scene reconstruction engine to form a digital volumetric scene model representing the real scene. The volumetric scene model (i) contains volumetric data elements defined by stored data representing one or more media characteristics and (ii) contains solid angle data elements defined by stored data representing the flux of the light field. Adjacent volumetric data elements form corridors, at least one of the volumetric data elements in at least one corridor represents media that is partially light transmissive.Type: ApplicationFiled: January 25, 2024Publication date: May 23, 2024Inventors: David Scott ACKERSON, Donald J. MEAGHER, John K. LEFFINGWELL, Kostas DANIILIDIS

Patent number: 10991036Abstract: A method for automatically mapping a store layout includes identifying a path for traversing a retail area and capturing images of the retail area at various points along the path. The images may be analyzed to identify visual characteristics which may be compared to a template of retail products in a template library. When an object depicted in the image matches with a retail product in the template library, the object may correspond to the retail product. Additionally, a retail department for the object may also be identified. The retail department may be compared to the retail product corresponding to the object, and when the retail product is not associated with the retail department, another retail product which is associated with the retail department may be identified as corresponding to the object. A map of the store layout may be generated based on the identified retail products.Type: GrantFiled: May 26, 2020Date of Patent: April 27, 2021Assignees: WALGREEN CO., The Trustees of the University of PennsylvaniaInventors: John M. Bergstrom, Jonas Cleveland, Dinesh Thakur, Philip Dames, Cody Philips, Terry Kientz, Kostas Daniilidis, Vijay Kumar

Publication number: 20040021766Abstract: Provided is a multispectral and omnidirectional imaging sensor and system that produces improved surround awareness, as well as methods of use therefor. The multispectral omnidirectional optical sensor device comprises a series of view and reflecting mirrors for splitting the electromagnetic spectrum into two or more electromagnetic wavelength bands; in combination with a plurality of cameras that are spaced relative to the reflecting mirrors. Each camera senses one of the wavelength bands or the resulting signal passing through the mirrors and creates an image thereof (focussed on the same view), so that each image is automatically registered.Type: ApplicationFiled: January 31, 2003Publication date: February 5, 2004Inventors: Kostas Daniilidis, Elli Angelopoulou, Vijay Kumar
