Omni-directional intelligent autotour and situational aware dome surveillance camera system and method

摘要

A method of operating a video surveillance system includes providing a PTZ camera within a housing. A fisheye lens camera is attached to the housing such that the fisheye lens camera has a panoramic field of view that is unobstructed by the housing. The panoramic field of view is centered on a panning axis of the PTZ camera. The fisheye lens camera is rotated about the panning axis. A first image within the panoramic field of view is captured by using the fisheye lens camera. A location of an object of interest within the captured first image is identified. PTZ commands are transmitted to the PTZ camera such that the PTZ camera is oriented to capture a second image of the object of interest at the identified location. The PTZ commands are compensated for a rotation of the field of view of the fisheye lens camera during the rotation of the fisheye lens camera.

1. A method of operating a video surveillance system, comprising steps of:
providing a PTZ camera within a housing; securing a fisheye lens camera to the housing so that the fisheye lens camera has a panoramic field of view that is unobstructed by the housing, the panoramic field of view being centered on a panning axis of the PTZ camera, and wherein the panoramic field of view of the fisheye lens camera is coaxially aligned with the panning axis so that an essentially central point within an image from the panoramic field of view of the fisheye lens camera is in common with the panning axis of the PTZ camera; rotating the fisheye lens camera along the panning axis while the PTZ camera is simultaneously rotating about the panning axis, wherein boundaries of the image sensed by the fisheye lens camera remain the same and the image sensed by the fisheye lens camera rotates during the rotation of the fisheye lens camera; capturing a first image within the panoramic field of view by using the fisheye lens camera; identifying a location of an object of interest within the captured first image; and transmitting PTZ commands to the PTZ camera such that the PTZ camera is oriented to capture a second image of the object of interest at the identified location, the PTZ commands being compensated for a rotation of the panoramic field of view of the fisheye lens camera during the rotation of the fisheye lens camera.
