Problems solved by technology

Although PTZ cameras have the functions of omnidirectional rotation and zooming, there is still no surveillance system that can have the above functions at the same time. Most surveillance systems using PTZ cameras either only use the rotation function or th

Embodiment Construction

[0060]The present invention can be mainly divided into two parts: detection and tracking. After the picture captured by the PTZ image capture device is transmitted to the tracking module, the processor in the tracking module detects whether there is a moving object in the picture and controls the image capture. The device rotates accordingly to track the moving object, and when the moving object is within the zoom range of the image capture device, the processor can further adjust according to the needs, for example, the captured image of the moving object is too small and needs to be zoomed in, or the image is too large and needs to be zoomed out to adjust the focal length of the image capture device to obtain a clear image of the moving object.

[0061] Therefore, the spatially moving object locking and targeting device of the present invention includes an image capture device capable of omnidirectional rotation and zooming and a tracking module. Fig. 1 is a structural block ...

Abstract

Using image picking up device with functions of omnidirectional rotation and Pan-Tilt-Zoom (PTZ) tracks mobile object. After comparing current image picked up by the PTZ image picking up device with a previous image, processor defines mobile object in frame, based on the position of the mobile object, the method rotates the image picking up device to track the mobile object. When the mobile object enters into zooming range of the image picking up device, if the mobile object possesses too small or too large proportion in the frame, then the processor can adjust focus of the image picking up device to make the mobile object possess proper proportion in the frame in order to provide clear image with high resolution.

Description

technical field [0001] The present invention relates to a space-moving object locking and targeting device and its method, in particular to a space-moving object locking and targeting device using a camera with omnidirectional rotation and zoom (Pan-Tilt-Zoom, PTZ) functions to track a moving object and methods. Background technique [0002] In high-risk areas such as banks, buildings, shops, and parking lots, many monitors can be seen to monitor video from various angles or positions. After an accident, it is often necessary to use these surveillance video tapes to find possible clues from the screen. However, since ordinary monitors do not have the tracking function, they can only capture short-term pictures of suspicious persons passing by, and can provide little information. Therefore, a monitoring system with real-time tracking function was born accordingly. [0003] Real-time tracking systems can be broadly divided into two categories using fixed cameras or non-fixed ...
