Positional locating system and method
First Claim
Patent Images
1. A method of positionally identifying objects within a space comprising:
- associating an identification generated for one or more of the objects with a device to be worn while the corresponding object 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 object at each of the space-based positional coordinates based on the identification of one or more objects 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.
