Correlating captured images and timed 3D event data
First Claim
1. A method for correlating tracking data, associated with an activity occurring in a three-dimensional space, with images captured within the space, wherein remotely-accessible identification tags attached to people and/or objects associated with the activity are linked to one or more databases that uniquely identify characteristics of the people and/or objects, said method comprising the steps of:
- (a) locating a camera with respect to the three-dimensional space, wherein the camera at a given location has a determinable orientation and field of view that encompasses at least a portion of the space;
(b) capturing a plurality of images with the camera and storing data corresponding to the images, including a capture time for each image;
(c) capturing tracking data from the identification tags attached to the people and/or objects within the space and storing the tracking data, including a tag capture time for each time that a tag is remotely accessed;
(d) correlating each image and the tracking data by interrelating tracking data having a tag capture time in substantial correspondence with the capture time of each image, thereby generating track data corresponding to each image;
(e) utilizing the track data to determine positions of the people and/or objects within the three dimensional space at the capture time of each image; and
(f) utilizing the location and orientation of the camera to determine the portion of the space captured in each image and thereby reduce the track data to a track data subset corresponding to people and/or objects positioned within the portion of space captured in each image.

17. A system for correlating tracking data, associated with an activity occurring in a three-dimensional space, with images captured within the space, wherein remotely-accessible identification tags attached to people and/or objects associated with the activity are linked to one or more databases that uniquely identify characteristics of the people and/or objects, said system comprising:
-
an imaging system including one or more cameras located at given locations with respect to the three-dimensional space, wherein each camera has a determinable orientation and field of view that encompasses at least a portion of the space, thereby enabling the imaging system to capture a plurality of images of the portion of the space and store data corresponding to the images, including a capture time for each image; a tracking system for capturing tracking data from the identification tags attached to the people and/or objects within the space and storing the tracking data, including a tag capture time for each time that a tag is remotely accessed; and a correlation and data reduction stage for (1) correlating the selected image and the tracking data by interrelating tracking data having a tag capture time in substantial correspondence with the capture time of the selected image, thereby generating track data corresponding to the selected image;
(2) utilizing the track data to determine positions of the people and/or objects within the three dimensional space at the capture time of the selected image; and
(3) utilizing the location and orientation of the camera to determine the portion of the space captured in the selected image and thereby reduce the track data to a track data subset corresponding to people and/or objects positioned within the portion of space captured in the selected image. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
