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.
Claims27
A speed-based projection filtering method, comprising:
- receiving a periodic sequence of raw location points from a tracking tag attached to a tracked object;
- and
- determining, when a latest speed of the tracked object is greater than a high-speed threshold, one or more projected location points from the received sequence of raw location points in an absence of raw location points immediately after the received sequence.
A speed-based projection filtering system, comprising:
- at least one processor;
- a memory communicatively coupled with the at least one processor;
- and
- a speed-based projection filter implemented as machine-readable instructions stored in the memory and configured to control the processor to:
- receive and store in the memory a periodic sequence of raw location points from a tracking tag attached to a tracked object, and
- determine, when a latest speed of the tracked object is greater than a high-speed threshold, one or more projected location points from the received sequence of raw location points in an absence of raw location points immediately after the received sequence.
A multiple-tag correction filtering method, comprising:
- simultaneously generating first and second averaged location points of respective first and second tracking tags attached to a tracked object;
- and
- determining an orientation of the tracked object and a first object location point of the tracked object from the first and second averaged location points.
A multiple-tag correction filtering system, comprising:
- at least one processor;
- a memory communicatively coupled with the at least one processor;
- and
- a multiple-tag correction filter implemented as machine-readable instructions stored in the memory and configured to control the processor to:
- simultaneously generate first and second averaged location points of respective first and second tracking tags attached to a tracked object, and
- determine an orientation of the tracked object and a first object location point of the tracked object from the first and second averaged location points.
