A method of creating a local map includes: receiving, at a mobile electronic data processing apparatus, a request from a server to generate a map of a specified destination; sending to the server a message accepting the request to generate the map responsive to receiving, at a user input of the mobile electronic data processing device, a user command indicating acceptance of the request; generating, using a processor, information related to construction of the map; an transmitting, from the mobile electronic data processing apparatus, the information related to construction of the map.

Localized map generation

A method includes: receiving sensor measurements from a pre-processing module, in which the sensor measurements include image data and inertial data for a device; transferring, using a processor, information derived from the sensor measurements, from a first set of variables associated with a first window of time to a second set of variables associated with a second window of time, in which the first and second windows consecutively overlap in time; and outputting, to a post-processing module, a state of the device based on the transferred information.

Visual-based inertial navigation

The present system provides an on the fly simple to complex 6DOF registration approach using the direct method. On the fly means it does not require training time, a user points a phone/camera to a planar surface and can start tracking it instantly. Simple to complex means the system performs registration in multiple levels of complexity from 2DOF to 6DOF. By increasing the complexity model the system enables more surfaces to be tracked and for surfaces that are tracked the system can avoid local minima solution providing a more robust and accurate 6DOF tracking. Even surfaces that are very weak in features can be tracked in 6DOF and virtual content can be registered to them. The system enables playing Augmented Reality games on low-end devices such as mobile phones on almost any surface in the real world.
