Patent Images
1. Object tracking anti-jitter filtering method, comprising:
- receiving, within an object tracking system, a plurality of raw location points for a tracking tag attached to a tracked object;
storing the plurality of raw location points within a raw location points buffer;
averaging the raw location points within an averaging window to generate a first averaged location point; and
storing the averaged location point within an averaged location points buffer for use within the object tracking system;
wherein a period of the averaging window is based upon most recent speed of the tracked object, and is between a minimum period and a maximum period.

Abstract
Object tracking anti-jitter filtering systems and methods. A plurality of raw location points for a tracking tag attached to a tracked object is received. The raw location points are stored within a raw location points buffer. Raw location points within an averaging window are averaged to generate an averaged location point. The averaged location point is stored within an averaged location points buffer for use within the object tracking system.

13. Object tracking anti-jitter filtering system, comprising:
-
at least one processor; memory coupled with the processor for storing raw location points of a tracked object; an averaging filter, comprising machine readable instructions stored within the memory and executed by the processor, for averaging a plurality of the raw location points within an averaging window to generate an averaged location point having reduced jitter when compared to raw location points of the tracked object; and
,a speed based period controller, comprising machine readable instructions stored within the memory and executed by the processor, for incrementally increasing a period of the averaging window when a latest speed of the tracked object is less than a predefined low speed threshold, and for decreasing the period when the latest speed is greater than a predefined high speed threshold. - View Dependent Claims (14, 15, 16, 17, 18)
