Patent number: 11915453Abstract: Eyewear providing an interactive augmented reality experience between two eyewear devices by using alignment between respective 6DOF trajectories, also referred to herein as ego motion alignment. An eyewear device of user A and an eyewear device of user B track the eyewear device of the other user, or an object of the other user, such as on the user's face, to provide the collaborative AR experience. This enables sharing common three-dimensional content between multiple eyewear users without using or aligning the eyewear devices to common image content such as a marker, which is a more lightweight solution with reduced computational burden on a processor. An inertial measurement unit may also be used to align the eyewear devices.Type: GrantFiled: February 7, 2023Date of Patent: February 27, 2024Assignee: SNAP INC.Inventors: Branislav Micusik, Georgios Evangelidis, Daniel Wagner

Publication number: 20230401796Abstract: A method for aligning coordinate systems from separate augmented reality (AR) devices is described. In one aspect, the method includes generating predicted depths of a first point cloud by applying a pre-trained model to a first single image generated by a first monocular camera of a first augmented reality (AR) device, and first sparse 3D points generated by a first SLAM system at the first AR device, generating predicted depths of a second point cloud by applying the pre-trained model to a second single image generated by a second monocular camera of the second AR device, and second sparse 3D points generated by a second SLAM system at the second AR device, determining a relative pose between the first AR device and the second AR device by registering the first point cloud with the second point cloud.Type: ApplicationFiled: August 23, 2022Publication date: December 14, 2023Inventors: Georgios Evangelidis, Branislav Micusik, Jakob Zillner, Nathan Jacob Litke

Publication number: 20230359038Abstract: Eyewear having unsynchronized rolling shutter (RS) cameras such that images produced by each camera are unaligned, and a state that includes velocity and gravity orientation in the eyewear's reference system is calculated. The state is not limited to these two parameters as other parameters such as the acceleration bias, the gyroscope bias, or both may be included. Math solvers are used such that processing time to calculate the velocity and gravity orientation are acceptable. Arranging the RS cameras in an unsynchronized configuration allows estimating the motion of the eyewear from just one stereo image pair and removes the requirement of possessing more images.Type: ApplicationFiled: July 19, 2023Publication date: November 9, 2023Inventors: Branislav Micusik, Georgios Evangelidis

Publication number: 20230267691Abstract: A method for detecting changes in a scene includes accessing a first set of images and corresponding pose data in a first coordinate system associated with a first user session of an augmented reality (AR) device and accessing a second set of images and corresponding pose data in a second coordinate system associated with a second user session. The method identifies the first set of images corresponding to a second image from the second set of images based on the pose data of the first set of images being determined spatially closest to the pose data of the second image after aligning the first coordinate system and the second coordinate system. A trained neural network generates a synthesized image from the first set of images. Features of the second image are subtracted from features of the synthesized image. Area of changes are identified based on the subtracted features.Type: ApplicationFiled: February 22, 2022Publication date: August 24, 2023Inventor: Branislav Micusik

Patent number: 11450022Abstract: A method for detecting a loop closure is described. A device accesses pose information and a three-dimensional map of feature points generated by a visual inertia system of the device. The device splits the pose information into a translational part and a rotational part. The device limits the translational part to two-dimensional coordinates and estimates two-dimensional information of the limited translational part based on an accumulator voting space. The device determines an updated pose of the device based on the estimated two-dimensional information, the rotational part, and the three-dimensional map. The pose information is updated with the updated pose.Type: GrantFiled: October 27, 2020Date of Patent: September 20, 2022Assignee: RPX CorporationInventor: Branislav Micusik

Patent number: 10586395Abstract: A system and method for offloading object detection are described. A server receives first sensor data from a first sensor of an augmented reality (AR) display device. The first sensor data indicates a pose of the AR display device relative to a first reference coordinate system. The server detects a physical object using second sensor data received from a second sensor of the AR display device. The server determines, based on the second sensor data, a pose of the physical object relative to the AR display device.
