System and method for managing moving surveillance cameras

Abstract

An approach that manages moving surveillance cameras is described. In one embodiment, there is a system for managing images generated from a movable camera. In this embodiment, the system comprises a motion estimation component configured to determine camera motion. A camera motion alert component is configured to generate an alert in response to a determination that the camera has moved or the camera has ceased moving.

Description

technical field [0001] The present disclosure relates generally to video camera systems, and more particularly to steerable video surveillance cameras. Background technique [0002] Most recently available video surveillance analysis systems rely on background subtraction to detect interest by comparing incoming video frames with a background model that provides a reference representation of what the video camera should see if no moving objects were present. The goal. The background model is created by a background maintenance program that knows what is normal for each pixel or local area of ​​the camera's field of view. These types of video surveillance analysis systems work on the assumption that the camera is not moving and that any pixel will continue to see the same area of ​​the real world. If this assumption is violated, i.e. the camera is moved, the pixels will receive light from different parts of the real-world scene, and differences not due to scene changes will...

Problems solved by technology

[0005] These methods work well for stabilizing small camera motions, but stabilize large camera motions that exceed the range of the mechanical actuator's ability to move the individual lenses or sensors to compensate, or are so large that the compensation mechanisms are introduced due to their inherent Problems other types of image distortion have no effect during motion

Furthermore, these methods do not work well for camera motion that cannot be handled by compensation methods capable of compensating for camera motion (such as twisting of the camera around its optical axis)
