POSITIONAL LOCATING SYSTEM AND METHOD

摘要

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.

1. A method of positionally identifying football players within a football field comprising:
associating an identification generated for one or more of the football players with a head device to be worn while the corresponding football player moves within the football field; controlling a beacon included within each head 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 football field, each image plotting recorded signals within a two-dimensional field defined by 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 two-dimensional field of each image; reducing the image-based positional coordinates to field-based positional coordinates, the field-based positional coordinates defining spatial positioning of one or more beacons emitting the signals within at least a two-dimensional coordinate system defined relative to at least a length and width of the football field; and for each of the images, identifying the football player at each of the field-based positional coordinates based on the identification of one or more football players scheduled to emit signals at the time the image was captured.
