Method and computer program for generating a database for use in locating mobile devices based on imaging
First Claim
1. A method for generating a database of pixel patterns with positional information using a mobile device with at least one imaging system, comprising:
- obtaining at least one image using the at least one imaging system of the mobile device, each of the at least one image including a pattern of pixels;
determining a position of the mobile device using a positioning system at least partly situated on the mobile device when each of the at least one image is obtained;
generating a positional relationship between a size and/or angular orientation of the pattern of pixels and an associated determined position of the mobile device when the at least one image including the pattern of pixels was obtained that enables determination of an estimation of the position of the mobile device upon input of another image including the pattern of pixels; and
storing in the database, the generated positional relationship between the size and/or angular orientation of the pattern of pixels and the associated determined position of the mobile device.

Abstract
Method, system and computer program for generating a database of pixel patterns includes obtaining images using an imaging system of mobile devices, each image including a pixel pattern, and determining a position of the mobile device using a positioning system at least partly situated on the mobile device when each image is obtained using the imaging system of the mobile device. Positional relationships between a size and/or angular orientation of the pattern of pixels and an associated determined position of the mobile device when the at least one image including the pattern of pixels was obtained are generated and enables retrieval of an estimation of the position of the mobile device upon input of another image including the pattern of pixels. The generated positional relationships between the size and/or angular orientation of the pattern of pixels and the associated determined position of the mobile device are stored in a database.

14. A computer program embodied in non-transitory computer readable media for generating a database of pixel patterns with positional information using a mobile device with at least one imaging system, the computer program being configured to:
-
receive at least one image from the at least one imaging system of the mobile device, each of the at least one image including a pattern of pixels; determine a position of the mobile device using a positioning system at least partly situated on the mobile device when each of the at least one image is obtained; generate a positional relationship between a size and/or angular orientation of the pattern of pixels and an associated determined position of the mobile device when the at least one image including the pattern of pixels was obtained that enables determination of an estimation of the position of the mobile device upon input of another image including the pattern of pixels; and store in the database, the generated positional relationship between the size and/or angular orientation of the pattern of pixels and the associated determined position of the mobile device. - View Dependent Claims (15, 16, 17, 18, 19)

20. A mobile device-based system for generating a database of pixel patterns with positional information using a mobile device with at least one imaging system, comprising:
-
at least one imaging system configured to obtain images each including a pattern of pixels; a positioning system configured to determine a position of the mobile device when each image is obtained; a processor configured to generate a positional relationship between a size and/or angular orientation of the pattern of pixels and an associated determined position of the mobile device when each image was obtained that enables determination of an estimation of the position of the mobile device upon input of another image including the pattern of pixels; and a database configured to store the generated positional relationship between the size and/or angular orientation of the pattern of pixels and the associated determined position of the mobile device.
