Image processing system and method for improving repeatability
First Claim
1. A system for improving camera repeatability based on a stored video image and a stored camera position corresponding to the stored video image, the system comprising:
- a drive mechanism configured to move the camera to a plurality of different positions during a surveillance operation;
a memory for storing a plurality of video images as a camera moves to the plurality of different positions and for storing a camera position corresponding to each stored video image, the drive mechanism being configured to return the camera to a selected stored camera position;
image processing components for comparing a current video image captured at the selected stored camera position with the stored video image previously captured at the selected stored camera position by using a stationary object in the stored video image and the current video image to determine a position offset; and
an adjustment mechanism for adjusting a current camera position based on the determined position offset to align the current video image with the stored video image.

Abstract
Embodiments of the invention relate to a dome camera assembly that is able to ensure repeatability. The dome camera assembly includes a nonvolatile storage mechanism including a stored video image and a corresponding stored camera position. The assembly may further include an image capturing device for capturing a current video image after the camera moves to the stored camera position. An image processing component compares the current video image with the stored video image and determines an offset amount between the current video image and the stored video image. An adjustment mechanism adjusts a current camera position in accordance with the determined offset amount to facilitate repeatability.
