Estimating the term…
The system includes a base unit sensitive to infrared (IR) signals transmitted by a mobile remote unit to an IR receiver which is placed behind a rotating set of signal blocking blinders whose position at any time defines a view angle with a position known with precision resulting in the IR signal reception scanning across an area. The base unit detects when the peak strength of the signal occurs and utilizes this data to determine the exact effective angle between the axis of the IR signal and the base unit to create an error signal used by the base unit to position the camera mounted thereon. Receivers for TILT and two PAN positions, PAN 1 and PAN 2, are used to include range calculations for ZOOM functions. Command circuitry to override the automatic tracking function is provided in the base unit.
A method of calculating the angular displacement of a moving object with respect to a reference angle and moving a movable means to automatically follow and track the moving object in response thereto comprising:
A method of controlling the field of view of a camera operatively connected to a tracking unit that is movable by a controller to track by automatically positioning on a movable remote control unit and following same for taking pictures by the camera comprising the steps of:
A system for positioning and operating a camera that is movable to automatically follow and track a movable remote control unit for taking pictures by the camera comprising a movable tracking unit for mounting of a camera thereon, transmitter means at said remote control unit for transmitting a signal in the electromagnetic spectrum, scanning means including view angle control means for controlling the angular displacement with respect to a reference position at which said receiver means can receive said transmitted signal, and an automatic controller means for determining the displacement between the angle of reception of said transmitted signal and said reference position and for automatically controlling the movement of said tracking unit to track and follow a moving said control unit in response to the displacement so determined.
