Methods and apparatus for operating a pan tilt zoom camera
First Claim
1. A video camera assembly comprising:
- a video camera;
a pan mechanism configured to rotate the video camera about a pan axis;
a tilt mechanism coupled to said pan mechanism, said tilt mechanism configured to rotate the video camera about a tilt axis; and
a controller communicatively coupled to said pan and tilt mechanisms, said controller configured to;
receive a first image of a view acquired from a first address;
receive a second image of the view acquired from a second address wherein the second address is different from the first address;
compare the first image to the second image; and
determine an offset between the first address and the second address using the comparison.

Abstract
Methods and systems for a video camera assembly are provided. The video camera assembly includes a video camera, a pan mechanism configured to rotate the video camera about a pan axis, a tilt mechanism coupled to the pan mechanism wherein the tilt mechanism is configured to rotate the video camera about a tilt axis, and a controller communicatively coupled to the pan and tilt mechanisms. The controller is configured to receive a first image of a view acquired from a first address, receive a second image of the view acquired from a second address wherein the second address is different from the first address, compare the first image to the second image, and determine an offset between the first address and the second address using the comparison.

6. A method of calibrating a video camera assembly that includes a video camera and at least one of a pan mechanism, a tilt mechanism, and a zoom for defining a field of view of the camera, the pan mechanism configured to rotate the video camera about a pan axis, the tilt mechanism configured to rotate the video camera about a tilt axis, said method comprising:
-
acquiring a first image of a view using a first camera assembly positional address;
acquiring a second image of the view using a second camera assembly positional address, the second camera assembly positional address being a conjugate address with respect to the first camera assembly positional address;
comparing the first and second images to determine an offset between the first and second images; and
applying the offset to each camera assembly positional address and conjugate address. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A method of operating a video camera assembly that includes a video camera and at least one of a pan mechanism, a tilt mechanism, and a zoom for defining a field of view of the camera, said method comprising:
-
receiving a preset command;
determining an address from a plurality of addresses associated with the preset command;
transmitting movement commands to the at least one of a pan mechanism, a tilt mechanism, and a zoom; and
repositioning the camera assembly in response to the movement commands to a position associated with the address. - View Dependent Claims (17, 18, 19, 20)
