Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for 3D flight tracking of objects include a method including determining a golf ball trajectory based on observations by sensor(s), extrapolating the trajectory backward in time, calculating distance measure(s) between the extrapolated trajectory and physical locations, determining one of the physical locations to be an origin of the golf ball based on the distance measure(s) and two types of separately estimated errors, wherein a first of the two types of separately estimated errors affects ball positional error for the initial observations, and a second of the two types of separately estimated errors affects an angle of the extrapolated trajectory; and presenting golf ball data on a display device associated with the origin of the golf ball.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for 3D flight tracking of objects include a method including determining a three dimensional trajectory based on initial observations, extrapolating the three dimensional trajectory backward in time to generate an extrapolated trajectory, calculating distance measures between the extrapolated trajectory and defined physical locations, waiting for additional observations when none of the distance measures satisfy a threshold distance, identifying one of the defined physical locations as an origin when only one of the distance measures satisfies the threshold distance and an error measure satisfies a predefined criteria, identifying one of the defined physical locations as the origin when two of the distance measures satisfy the threshold distance and only one of first and second error measures satisfies the predefined criteria, and waiting for additional observations when neither the first error measure nor the second error measure satisfies the predefined criteria.

Abstract: A method includes assessing errors for golf shots using observations by sensor(s), the assessing being in accordance with variations in a location for the sensor(s), and providing a map indicating at least one preferred location for the sensor(s) for use in setting up an object tracking system. Further, a method includes assessing how an estimated error affects identification of an originating location for a golf shot, including projecting a first value of the error back to the originating location and multiplying a second value of the error by a distance to the originating location, and identifying the originating location for the golf shot based on a first effect of the error and a second effect of the error. Finally, a system includes a building including tee areas, targets, and a sensor system including sensor(s), in which a dedicated sensor system is not included for any one of the tee areas.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for 3D flight tracking of objects include a method including: determining at least one three dimensional trajectory for at least one golf ball hit into a three dimensional physical space based on observations by at least one golf ball sensor placed adjacent to the three dimensional physical space; calculating systemic and stochastic errors for the at least one three dimensional trajectory in accordance with variations in golf ball launching position, variations in locations for the at least one golf ball sensor, or both; and presenting a report showing a summary of the calculated systemic and stochastic errors to indicate preferred hitting positions, a different location for the at least one golf ball sensor, or both.
