Patent number: 12217380Abstract: System and method are provided for scaling a 3-D representation of a building structure. The method includes obtaining world map data including a first track of real-world poses for a plurality of images. The plurality of images comprises non-camera anchors. The method also includes detecting a discrepancy in at least one real-world pose of the first track. The method also includes in response to detecting a discrepancy, generating a new track of real-world poses. The method also includes calculating a scaling factor for a 3-D representation of the building structure based on sampling across a plurality of tracks. The plurality of tracks comprises at least the first track and the new track.Type: GrantFiled: June 8, 2023Date of Patent: February 4, 2025Assignee: Hover Inc.Inventors: Manish Upendran, William Castillo, Jena Dzitsiuk, Yunwen Zhou, Matthew Thomas, Giridhar Murali, Atulya Shree

Publication number: 20240029384Abstract: System and method are provided for scaling a 3-D representation of a building structure. The method includes obtaining images of the building structure, including non-camera anchors. The method also includes identifying reference poses for images based on the non-camera anchors. The method also includes obtaining world map data including real-world poses for the images. The method also includes selecting candidate poses from the real-world poses based on corresponding reference poses. The method also includes calculating a scaling factor for a 3-D representation of the building structure based on correlating the reference poses with the selected candidate poses. Some implementations use structure from motion techniques or LiDAR, in addition to augmented reality frameworks, for scaling the 3-D representations of the building structure. In some implementations, the world map data includes environmental data, such as illumination data, and the method includes generating or displaying the 3-D representation.Type: ApplicationFiled: October 4, 2023Publication date: January 25, 2024Inventors: Manish Upendran, William Castillo, Jena Dzitsiuk, Yunwen Zhou, Matthew Thomas

Publication number: 20230236219Abstract: Disclosed is a method including receiving a depth map estimated using data based on image and data received from a movement sensor as input, generating an alignment parameter based on the depth map, adding the alignment parameter to a pre-calibration state to define a user operational calibration state, generating scale parameters and shift parameters based on features associated with the data received from the image and movement sensor, and calibrating the image and movement sensor based on the user operational calibration state, the scale parameters and the shift parameters.Type: ApplicationFiled: January 21, 2022Publication date: July 27, 2023Inventors: Yunwen Zhou, Ryan Christopher DuToit, Abhishek Kar, Konstantine Nicholas John Tsotsos, Eric Turner, Chao Guo
