Abstract: A crowd-sourced modeling system to perform operations that include: receiving image data that comprises image attributes; accessing a 3D model based on at least the image attributes of the image data, wherein the 3D model comprises a plurality of parts that collectively depict an object or environment; identifying a change in the object or environment based on a comparison of the image data with the plurality of parts of the 3D model, the change corresponding to a part of the 3D model from among the plurality of parts; and generating an update to the part of the 3D model based on the image attributes of the image data.

Abstract: An addressable media system for performing operations that include: accessing image data that depicts an object in an environment at a client device; causing display of a presentation of the image data within a graphical user interface at the client device; detecting the display of the object within the presentation of the image data based on at least a portion of the plurality of image features of the display of the object; identifying an object class based on at least the portion of the image features of the display of the object; receiving an input that selects the display of the object from the client device; and associating the object class that corresponds with the object with the user profile in response to the input that selects the display of the object.

Abstract: An augmented reality system to perform operations that include: accessing image data at a client device; determining a position of a user of the client device based on the image data; causing display of a projection that extends from the position of the user upon a presentation of the image data at the client device; detecting an intersection of the projection and a surface of an object; generating a request that includes an identification of the portion of the surface of the object at the client device; and presenting the portion of the surface of the object based on the graphical property of the projection at the client device in response to the request that includes the identification of the portion of the surface of the object.

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.
