Patent number: 11380051Abstract: Systems and methods for image based location estimation are described. In one example embodiment, a first positioning system is used to generate a first position estimate. Point cloud data describing an environment is then accessed. A two-dimensional surface of an image of an environment is captured, and a portion of the image is matched to a portion of key points in the point cloud data. An augmented reality object is then aligned within one or more images of the environment based on the match of the point cloud with the image.

Patent number: 10055895Abstract: Systems and methods for local augmented reality (AR) tracking of an AR object are disclosed. In one example embodiment a device captures a series of video image frames. A user input is received at the device associating a first portion of a first image of the video image frames with an AR sticker object and a target. A first target template is generated to track the target across frames of the video image frames. In some embodiments, global tracking based on a determination that the target is outside a boundary area is used. The global tracking comprises using a global tracking template for tracking movement in the video image frames captured following the determination that the target is outside the boundary area. When the global tracking determines that the target is within the boundary area, local tracking is resumed along with presentation of the AR sticker object on an output display of the device.Type: GrantFiled: January 29, 2016Date of Patent: August 21, 2018Assignee: Snap Inc.Inventors: Jia Li, Linjie Luo, Rahul Sheth, Ning Xu, Jianchao Yang

Publication number: 20180007286Abstract: Systems and methods are described for receiving, at a computing device, a video comprising a plurality of frames and determining, by the computing device, that vertical cropping should be performed for the video. For each frame of the plurality of frames, the computing device processes the video by analyzing the frame to determine a region of interest in the frame, wherein the frame is a first frame, cropping the first frame based on the region of interest in the frame to produce a vertically cropped frame for the video, determining a second frame immediately preceding the first frame, and smoothing a trajectory from the second frame to the vertically cropped frame. The vertically cropped frame is displayed to a user instead of the first frame.Type: ApplicationFiled: July 1, 2016Publication date: January 4, 2018Inventors: Jia Li, Nathan Litke, Jose Jesus (Joseph) Paredes, Rahul Sheth, Daniel Szeto, Ning Xu, Jianchao Yang
