Positional locating system and method

Patent Images
1. A method of positionally identifying persons within a space comprising:
- associating an identification generated for one or more of the persons with a device to be worn while the corresponding person moves within the space;
controlling a beacon included within each device to emit a signal at an interval specified within a beacon transmission schedule;
controlling one or more cameras to capture images representative of at least a portion of the space, each image plotting recorded signals relative to a viewing angle of the corresponding camera;
calculating image-based positional coordinates for each signal appearing within each of the captured images, the image-based positional coordinates defining spatial positioning of one or more beacons emitting the signals relative to the viewing angle of the corresponding camera;
reducing the image-based positional coordinates to space-based positional coordinates, the space-based positional coordinates defining spatial positioning of one or more beacons emitting the signals within at least a coordinate system defined relative to the space; and
for each of the images, identifying the person at each of the space-based positional coordinates based on the identification of one or more persons scheduled to emit signals at the time the image was captured.

Abstract
A method and system are disclosed for locating or otherwise generating positional information for an object, such as but not limited generating positional coordinates for an object attached to an athlete engaging in an athletic event. The positional coordinates may be processed with other telemetry and biometrical information to provide real-time performance metrics while the athlete engages in the athletic event.

11. A non-transitory computer-readable medium having a plurality of non-transitory instructions operable with a processor to facilitate generating positional coordinates for a plurality of persons moving within a space, the non-transitory instructions being sufficient for:
-
instructing objects attached to one or more of the persons to emit a locating signal according to a schedule; capturing images of the space in which the plurality of objects are moving with one or more cameras, each image fixing a representation of any locating signals appearing at a time of capture; calculating positional coordinates for each of the representations, the positional coordinates reflecting a position of the object at the time of capture relative to the camera capturing the image having the representation; and associating the positional coordinates with the one or more persons by cross-referencing the positional coordinates for each time of capture with the one or more of the plurality of moving objects scheduled to emit the locating signal at the time of capture. - View Dependent Claims (12, 13, 14, 15, 16)

17. A system for providing video replay of persons moving within a space comprising:
-
a plurality of devices to be worn on one or more of the persons, each device each having a beacon configured to emit a signal; one or more cameras configured to record video of at least a portion of the space within an area defined by a viewing angle of the corresponding camera; one or more processors configured to; i) set a broadcast schedule for each of the plurality of devices, the broadcast schedule specifying a period of time during which each beacon is to emit the signal; and ii) generate positional coordinates for each beacon appearing within one or more video frames included within the video, the positional coordinates being generated based on the one or more beacons scheduled to emit the signal at the time a corresponding one of the video frames was recorded and a position of the camera recording the corresponding video frame; and iii) generate performance metrics for the one or more persons as a function of the positional coordinates generated for each person as the corresponding person is recorded within multiple video frames. - View Dependent Claims (18, 19)
