1. A system for tracking a velocity of an object, comprising:
- a first tracking device aimed so that a first field of view of the first tracking device covers at least a portion of a target volume into which an object is to be launched from a launch location; and
a processor receiving data from the first tracking device and identifying from the data velocity data of the object over time, the processor identifying a first transition point in the velocity data as a point at which a change in one of a velocity and an acceleration of the object is greater than a set threshold, the processor identifying the first transition point as a first point at which the object transitions from a first one of a bouncing state and a sliding state to a second one of the bouncing state, the sliding state and a rolling state.

Abstract
A system for tracking an object includes a first tracking device aimed so that a first field of view of the first tracking device covers at least a portion of a target volume into which an object is to be launched from a launch location and a processor receiving data from the tracking device and identifying from the data the velocity of the object over time, the processor identifying, based on changes in the velocity of the object over time, a first portion of a path of the object during which the object was in one of a bouncing state and a sliding state.

13. A method for tracking a movement of an object, comprising:
-
positioning a first tracking device aimed so that a first field of view of the first tracking device covers at least a portion of a target volume into which an object is to be launched from a launch location; determining, using a processor, based on data received from the first tracking device, a velocity value of the object at each of a plurality of time points to generate a velocity curve as a function of the velocity values over time; identifying transition points in the velocity curve as points at which a change in one of the velocity value of the object and a derivative of the velocity curve is greater than a set threshold; and separating the velocity curve into a plurality of segments, wherein each segment is identified as one of a bouncing state, a sliding state and a rolling state based in part on a slope of the velocity curve of the segment, wherein the transition points are points at which the object transitions from a first one of the bouncing state and the sliding state to a second one of the bouncing state, the sliding state and the rolling state. - View Dependent Claims (14, 15)
