System and method for object tracking anti-jitter filtering
First Claim
Patent Images
1. An object tracking anti-jitter filtering method, the method comprising:
- periodically receiving, within an object tracking system, a raw location point for a tracking tag attached to a tracked object;
averaging raw location points corresponding to an averaging window to periodically generate an averaged location point; and
determining physical movement of the tracked object based upon three most recently determined average location points corresponding to the object; and
adjusting a most recent of the three average location points such that the determined physical movement of the tracked object does not exceed predefined physical limits of the tracked object.

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.

9. An object tracking anti-jitter filtering system, the 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, capable of 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 physical limit filter, comprising machine readable instructions stored within the memory and executed by the processor, capable of adjusting a most recent of the averaged location point when one or both of a latest speed of the tracked object and an acceleration of the tracked object exceeds maximum physical characteristics of the tracked object; wherein the averaged location point is set to a location, relative to a previous averaged location point, that is within the maximum physical characteristics.
