Systems and methods for modeling structures using point clouds derived from stereoscopic image pairs
Patent number: 11915368Abstract: A system for modeling a roof structure comprising an aerial imagery database and a processor in communication with the aerial imagery database. The aerial imagery database stores a plurality of stereoscopic image pairs and the processor selects at least one stereoscopic image pair among the plurality of stereoscopic image pairs and related metadata from the aerial imagery database based on a geospatial region of interest. The processor identifies a target image and a reference image from the at least one stereoscopic pair and calculates a disparity value for each pixel of the identified target image to generate a disparity map. The processor generates a three dimensional point cloud based on the disparity map, the identified target image and the identified reference image. The processor optionally generates a texture map indicative of a three-dimensional representation of the roof structure based on the generated three dimensional point cloud.Type: GrantFiled: August 16, 2021Date of Patent: February 27, 2024Assignee: Insurance Services Office, Inc.Inventors: Joseph L.

Patent number: 6961754Abstract: In a multimedia environment, end-users are provided with the ability to effectively access, manipulate and share one or more multimedia objects, or select portions thereof, independent of the terminal and/or network capabilities that are associated with the terminals employed by each end-user. This may be accomplished, for example, by identifying a set of multimedia data that is stored in a multimedia database that is accessible by each end-user. The set of multimedia data is then adapted in accordance with an information adaptation service and modified in accordance with a transcoder/scalability service. The functions provided by both of these services are based on a number of user preferences and based on a number of terminal and communication (e.g., network) connection capabilities associated with the terminals corresponding to each of the end-users that are to have access to the modified set of multimedia data.Type: GrantFiled: January 12, 2001Date of Patent: November 1, 2005Assignee: Telefonaktiebolaget LM EricssonInventors: Charilaos Christopoulos, Niklas Björk, Francisco Rivas, Göran A P Eriksson
