Abstract

The embodiment discloses an improved Augmented Reality Multi Marker Positioning system that detects the distance and relative position of each marker, correlates the detected multiple markers and dynamically renders different objects for a single marker.

Claims (19)

1. A method of rendering virtual objects in an augmented reality environment, said method comprising:

identifying a plurality of markers in said augmented reality environment;

calculating distance and relative positions of each of said plurality of markers in said augmented reality environment;

rendering dynamically different virtual objects corresponding to each of said plurality of markers based on said calculated distance and relative positions of each of said plurality of markers;

calculating distance and relative by finding midpoints of each of said plurality of markers; and

finding line equation connecting said mid points.

2. The method according to claim 1 , wherein rendering said dynamically different virtual object is based on at least one predefined condition.

3. The method, according to claim 1 , wherein said identification of markers is based on at least one of image, video, sensor, identification string, bar code, actuator, infrared ray or Near Field Communication (NFC).

4. A device for rendering virtual objects in an augmented reality environment, wherein said device comprising:

an integrated circuit further comprising at least one processor;

at least one memory having a computer program code within said circuit;

said at least one memory and said computer program code configured to with said at least one processor cause the device to:

identify a plurality of markers in said augmented reality environment;

calculate distance and relative positions of each of said plurality of markers in said augmented reality environment;

render dynamically different virtual objects corresponding to each of said plurality of markers based on said calculated distance and relative positions of each of said plurality of markers;

calculate distance and relative positions by finding midpoints of each of said plurality of markers; and

finding line equation connecting said mid points.

5. The device, according to claim 4 , wherein said device is further configured to render said dynamically different virtual object based on at least one predefined condition.

6. The device, according to claim 4 , wherein said device is further configured to identify markers based on at least one of image, video, sensor, identification string, bar code, actuator, infrared ray or Near Field Communication (NFC).
