1. A method for correlating views of two or more video camera systems in an environment, the method comprising:
- (a) obtaining a first data point coordinate set corresponding to a first video camera system, the first data point coordinate set representing the location of a data point object in the environment relative to the first camera system, the first camera system providing an immersive view of the environment;
(b) obtaining a second data point coordinate set corresponding to a second video camera system, the second data point coordinate set representing the location of the data point object in the environment relative to the second camera system, wherein the second camera system comprises a pan-tilt-zoom video camera having a view of the environment that is narrower than the immersive view;
(c) storing the first and second data point sets as correlation data; and
(d) correlating the views of the first and second camera systems by referencing the correlation data and adjusting the view at least one of the video camera systems based on the correlation data.

Abstract
A method for correlating views of two or more video camera systems includes obtaining a plurality of data point coordinate sets to represent relative positioning between the camera systems and data point objects in the environment. The views may be correlated through Interpolation or extrapolation using the obtained data point coordinate sets. Devices such as lasers may also be used to correlate views of two or more video camera systems.

9. A method for correlating views of two or more video camera systems in an environment, the method comprising:
-
(a) capturing a image of a portion of the environment with a pan-tilt-zoom camera having a field of view;
(b) activating a laser beam to create a detectable reference on an object in the environment, the object being within the field of view of the PTZ camera;
(c) capturing an immersive image of the environment with an immersive camera system;
(d) identifying the detectable reference in the environment in the immersive image by virtue of the laser beam;
(e) determining the direction of the detectable reference relative the immersive camera; and
(f) correlating the pan-tilt-zoom and immersive cameras such that the object is viewable in the image and the immersive image. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for correlating views of two or more video camera systems, the method comprising:
-
(a) capturing an immersive video image of an environment with a first video camera system, the first video camera system having a wide-angle field of view;
(b) capturing a second video image of the environment with a second video camera system, the second video camera system having a field of view that is narrower than the wide-angle field of view, the second video camera system comprising a pan-tilt-zoom camera;
(c) activating a laser, the laser being oriented substantially parallel with the line of sight of the pan-tilt-zoom camera, the laser providing a detectable reference in the environment;
(d) detecting an object of interest in the immersive video image;
(e) detecting the detectable reference in the immersive video image;
(f) orienting the pan-tilt-zoom camera to capture the object of interest within the field of view of the pan-tilt-zoom camera based at least in part on the location of the detectable reference in the immersive video image. - View Dependent Claims (18, 19)

20. A video image capture system, comprising:
-
(a) a first video camera system configured to capture an immersive video image, the first video camera system providing a wide field of view of an environment;
(b) a second video camera system comprising a pan-tilt-zoom video camera, the pan-tilt-zoom video camera providing a narrow field of view within the wide field of view of the immersive video image; and
(c) a laser used for correlating the wide and narrow fields of view.
