Publication number: 20240135656Abstract: A cross reality system enables portable devices to access stored maps and efficiently and accurately render virtual content specified in relation to those maps. The system may process images acquired with a portable device to quickly and accurately localize the portable device to the persisted maps by constraining the result of localization based on the estimated direction of gravity of a persisted map and the coordinate frame in which data in a localization request is posed. The system may actively align the data in the localization request with an estimated direction of gravity during the localization processing, and/or a portable device may establish a coordinate frame in which the data in the localization request is posed aligned with an estimated direction of gravity such that the subsequently acquired data for inclusion in a localization request, when posed in that coordinate frame, is passively aligned with the estimated direction of gravity.Type: ApplicationFiled: December 26, 2023Publication date: April 25, 2024Applicant: Magic Leap, Inc.Inventors: Javier Victorio Gomez Gonzalez, Miguel Andres Granados Velasquez, Mukta Prasad, Dominik Michael Kasper, Eran Guendelman, Keng-Sheng Lin

Publication number: 20240062491Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously persisted maps of very large scale environments and render virtual content specified in relation to those maps. The cross reality system may build a persisted map, which may be in canonical form, by merging tracking maps from the multiple devices. A map merge process determines mergibility of a tracking map with a canonical map and merges a tracking map with a canonical map in accordance with mergibility criteria, such as, when a gravity direction of the tracking map aligns with a gravity direction of the canonical map. Refraining from merging maps if the orientation of the tracking map with respect to gravity is not preserved avoids distortions in persisted maps and results in multiple devices, which may use the maps to determine their locations, to present more realistic and immersive experiences for their users.Type: ApplicationFiled: August 28, 2023Publication date: February 22, 2024Applicant: Magic Leap, Inc.Inventors: Miguel Andres Granados Velasquez, Javier Victorio Gomez Gonzalez, Mukta Prasad, Eran Guendelman, Ali Shahrokni, Ashwin Swaminathan

Publication number: 20230119217Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously persisted maps, even maps of very large environments, and render virtual content specified in relation to those maps. The cross reality system may quickly process a batch of images acquired with a portable device to determine whether there is sufficient consistency across the batch in the computed localization. Processing on at least one image from the batch may determine a rough localization of the device to the map. This rough localization result may be used in a refined localization process for the image for which it was generated. The rough localization result may also be selectively propagated to a refined localization process for other images in the batch, enabling rough localization processing to be skipped for the other images.Type: ApplicationFiled: December 7, 2022Publication date: April 20, 2023Applicant: Magic Leap, Inc.Inventors: Miguel Andres Granados Velasquez, Javier Victorio Gomez Gonzalez, Danying Hu, Eran Guendelman, Ali Shahrokni, Ashwin Swaminathan, Mukta Prasad
