First Claim
Patent Images
1. A method to track an object comprising:
- directing a video imager to perform image recognition to recognize a feature of the object within an imager field of view and to determine a position of the feature within the field of view;
transmitting an infrared (IR) signal by an IR transmitter disposed upon the object;
using an IR sensor to determine a position of the infrared (IR) transmitter; and
automatically adjusting orientation of the imager based upon the position of the recognized feature within the field of view and the determined position of the IR transmitter to follow movement of the object.

Abstract
A method is provided to track an object, the method comprising: directing a video imager to perform image recognition to recognize a feature of the object within an imager field of view and to determine a position of the feature within the field of view; using an IR sensor to determine a position of an infrared (IR) transmitter; and automatically adjusting orientation of the imager as a function of the position of the recognized feature within the field of view and the determined position of the IR transmitter to follow movement of the object.

12. A system comprising:
-
a video imager configured to perform image recognition to recognize a feature of an object within an imager field of view and to determine a position of the feature within the field of view; an IR transmitter disposed upon the object to transmit an infrared (IR) signal; an IR sensor disposed to determine a position of the infrared (IR) transmitter; and means for determining a position as a function of a recognized feature within the field of view and a determined position of the IR transmitter. - View Dependent Claims (13, 14, 15)

16. A method to track an object comprising:
-
directing a video imager to capture video images of an object within an imager field of view; transmitting a first infrared (IR) signal by a first IR transmitter disposed upon the object to transmit the first IR signal in a first direction away from the object; transmitting a second IR signal by a second IR transmitter disposed to transmit the second IR signal in a second direction toward the object so that the second IR signal reflects off the object in a third direction away from the object; using an IR sensor to determine a position of the object based upon the first IR signal when the IR sensor is in a path of the first direction and to determine a position of the object based upon the second IR signal when the IR sensor is in a path of a path of the third direction; and automatically adjusting orientation of the imager to follow the object in the field of view based upon the determined position of the object. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A system comprising:
-
a video imager; a first IR transmitter disposed upon the object to transmit a first IR signal in a first direction away from the object; a second IR transmitter disposed to transmit a second IR signal in a second direction toward the object so that the second IR signal reflects off the object in a third direction away from the object; an IR sensor disposed to determine a position of the object based upon the first IR signal when the IR sensor is in a path of the first direction and to determine a position of the object based upon the second IR signal when the IR sensor is in a path of a path of the third direction; and means for automatically adjusting orientation of the imager to follow the object in the field of view based upon the determined position of the object. - View Dependent Claims (26, 27)

28. A method to tag video data with information about content of the video data comprising:
-
directing a video imager to capture video images of an object; using first sensor data generated by a sensor to detect position of the object; automatically adjusting orientation of the imager as a function of the detected position of the object so as to follow movement of the object; using second sensor data generated by a sensor to identify an event; and storing the video data in a computer readable storage device in association with time stamps to indicate the relative time of occurrence of different portions of the video data and in association with a tag that identifies the detected event and that is associated with a time stamp. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A system comprising:
-
a video imager; a first sensor; a second sensor; means for automatically adjusting orientation of the imager to follow an object within an imager field of view based upon object position information collected by the first sensor; and a machine readable storage device encoded with storing video data captured by the video imager in association with time stamps to indicate the relative time of occurrence of different portions of the video data and in association with a tag that identifies an event detected by the second sensor wherein the tag is associated with a time stamp. - View Dependent Claims (40, 41, 42, 43)
