    Abstract: An augmented reality system to generate and cause display of a presentation of a space at a first client device, receive one or more selections of points within the presentation of the space at the first client device, and render graphical elements at the one or more points within the presentation of the space at the first client device. The augmented reality system is further configured to receive a display request to display the space at a second client device, and in response, may render a second presentation of the space at the second client device, wherein the second presentation of the space includes the graphical elements at the one or more points.

    Abstract: Determining the position and orientation (or “pose”) of an augmented reality device includes capturing an image of a scene having a number of features and extracting descriptors of features of the scene represented in the image. The descriptors are matched to landmarks in a 3D model of the scene to generate sets of matches between the descriptors and the landmarks. Estimated poses are determined from at least some of the sets of matches between the descriptors and the landmarks. Estimated poses having deviations from an observed location measurement that are greater than a threshold value may be eliminated. Features used in the determination of estimated poses may also be weighted by the inverse of the distance between the feature and the device, so that closer features are accorded more weight.

    Abstract: Disclosed are augmented reality (AR) personalization systems to enable a user to edit and personalize presentations of real-world typography in real-time. The AR personalization system captures an image depicting a physical location via a camera coupled to a client device. For example, the client device may include a mobile device that includes a camera configured to record and display images (e.g., photos, videos) in real-time. The AR. personalization system causes display of the image at the client device, and scans the image to detect occurrences of typography within the image (e.g., signs, billboards, posters, graffiti).

    Abstract: An occlusion detection system to perform operations that include: capturing image data that depicts an environment at a client device, the environment including a target object at a position within the environment; causing display of a presentation of the environment at the client device, the presentation of the environment including a display of the target object at the position within the environment; detecting a first attribute of the display of the target object at the client device; performing a comparison of the first attribute of the display of the target object and a second attribute associated with the target object; and detecting an occlusion based on the comparison.

    Abstract: Methods and systems are disclosed for creating a shared augmented reality (AR) session. The methods and systems perform operations comprising: receiving, by a second device, a request to join an AR session initialized by a first device; in response to receiving the request, detecting a body corresponding to a user of the first device in one or more images captured by a camera of the second device; identifying a body part of the detected body corresponding to the user of the first device; determining, by the second device, a transformation in the AR session between the first device and the second device using the identified body part; and causing the AR session to be displayed by the second device based on the determined transformation.
