Abstract
Described herein is a system and method of generating precise location information. Feature points of an image are received from a user device (e.g., mobile phone). Location information of the user device (e.g., GPS coordinates) and relative transform information from the user device are also received. An image anchor is identified based upon the received feature points, relative transform information, and the received location information. Precise location information of the identified image anchor is provided to the user device. The precise location information of the identified image anchor is based upon filtered feature points, location information and relative transform information received from a plurality of user devices over a period of time (e.g., hours, days, weeks, months). The precise location information of the identified image anchor is updated based upon the location information of the user device and the relative transform information received from the user device.
