According to certain aspects, a server may access aerial and other image data and identify a set of parameters associated with the capture of the image data. The server may access a corresponding set of acceptable image capture parameters, and may compare the set of parameters to the set of acceptable parameters to determine whether image data is consistent with the set of acceptable parameters. In some embodiments, if the image data is not consistent, the server may generate a notification or instruction to cause an image capture component to recapture additional image data.Type: GrantFiled: February 20, 2018Date of Patent: March 10, 2020Assignee: STATE FARM MUTUAL AUTOMOBILE INSURANCE COMPANYInventors: Bradley A.

Patent number: 10499046Abstract: A camera system captures images from a set of cameras to generate binocular panoramic views of an environment. The cameras are oriented in the camera system to maximize the minimum number of cameras viewing a set of randomized test points. To calibrate the system, matching features between images are identified and used to estimate three-dimensional points external to the camera system. Calibration parameters are modified to improve the three-dimensional point estimates. When images are captured, a pipeline generates a depth map for each camera using reprojected views from adjacent cameras and an image pyramid that includes individual pixel depth refinement and filtering between levels of the pyramid. The images may be used to generate views of the environment from different perspectives (relative to the image capture location) by generating depth surfaces corresponding to the depth maps and blending the depth surfaces.Type: GrantFiled: April 18, 2017Date of Patent: December 3, 2019Assignee: Facebook, Inc.Inventors: Michael John Toksvig, Forrest Samuel Briggs, Brian Keith Cabral

Patent number: 10484561Abstract: A smartphone may be freely moved in three dimensions as it captures a stream of images of an object. Multiple image frames may be captured in different orientations and distances from the object and combined into a composite image representing an three-dimensional image of the object. The image frames may be formed into the composite image based on representing features of each image frame a set of points in a three dimensional depth map. Coordinates of the points in the depth map may be estimated with a level of certainty. The level of certainty may be used to determine which points are included in the composite image. The selected points may be smoothed and a mesh model may be formed by creating a convex hull of the selected points. The mesh model and associated texture information may be used to render a three-dimensional representation of the object on a two-dimensional display.Type: GrantFiled: May 11, 2015Date of Patent: November 19, 2019Assignee: ML Netherlands C.V.Inventors: Alexander Ilic, Benedikt Koeppel

Patent number: 10477195Abstract: Different full screen content is displayed on the same television at the same time from the perspective of the viewer by displaying as the content as two full screen sequential frames. The different full screen content may be provided as a single combined frame signal such as a side-by-side, top-bottom, or checkerboard signal which is then displayed as two sequential full screen frames. Configured glasses such as polarized or shutter are used to view the different content as full screen content where one pair of configured glasses views an initial one of the sequential frames but blocks the subsequent one and another pair of configured glasses blocks the initial one of the sequential frames and views the subsequent one. Shutter glasses have both lenses open during the initial frame and both closed during the subsequent one. For polarized glasses, the initial frame has a polarization matching both lenses of one pair of glasses while the subsequent frame has a polarization that differs from both lenses.Type: GrantFiled: July 13, 2017Date of Patent: November 12, 2019Inventor: Jeramie J.

Patent number: 10373337Abstract: A method is provided for calibrating a stereo imaging system by using at least one camera and a planar mirror. The method involves obtaining at least two images with the camera, each of the images being captured from a different camera position and containing the mirror view of the camera and a mirror view of an object, thereby obtaining multiple views of the object. The method further involves finding the center of the picture of the camera in each of the images, obtaining a relative focal length of the camera, determining an aspect ratio in each of the images, determining the mirror plane equation in the coordinate system of the camera, defining an up-vector in the mirror's plane, selecting a reference point in the mirror's plane, determining the coordinate transformation from the coordinate system of the image capturing camera into the mirror coordinate system, and determining a coordinate transformation.Type: GrantFiled: March 18, 2016Date of Patent: August 6, 2019Assignee: Lateral Reality KFT.Inventor: Péter Torma
