Problems solved by technology

[0009] Due to the above limitations of traditional approaches to tracking technology, current AR user experiences may feel unnatural
Also, most users are unlikely to know or understand the motion necessary for traditional tracking initialization using two reference images
Typical users are also often confused as to why they have to perform a particular movement before the augmented reality system can display the scene's tracking updates

Abstract

Disclosed are a system, apparatus, and method for in-situ creation of planar natural feature targets. In one embodiment, a planar target is initialized from a single first reference image one or more subsequent images are processed. In one embodiment, the planar target is tracked in six degrees of freedom upon the processing of the one or more subsequent images and a second reference image is selected from the processed one or more subsequent images. In one embodiment, upon selecting the second reference image the planar target is refined to a more accurate planar target.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority to U.S. Application No. 13 / 802,834, filed March 14, 2013, entitled "In Situ Creation of Planar Natural Feature Targets," which is assigned to the present recipient. It is hereby incorporated by reference in its entirety. technical field [0003] The subject matter disclosed herein generally relates to planar target formation and tracking. Background technique [0004] Camera sensor data or images can be used as input for building a 3D map of the environment. In augmented reality (AR) systems, virtual objects can be inserted into a device display that interact with or replace real / physical world objects. An AR system may incorporate input from a camera sensor to record real-world objects as images or video, and display the AR view on a device display. [0005] AR systems may implement a tracking system to estimate the user's position and orientation (pose) relative...
