Embodiment Construction

[0018] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[0019] FIG. 1 is a block diagram showing a device 100 for moving object detection and tracking based on a moving camera according to the present invention.

[0020] Referring to FIG. 1 , the device 100 includes five parts: a feature detection unit 101 , a feature tracking unit 105 , a potential motion detection unit 110 , a motion analysis unit 115 and an object tracking unit 120 . In device 100 , video is input to feature detection unit 101 , feature tracking unit 105 and object tracking unit 120 .

[0021] The feature detection unit 101 finds corner points (ie, feature points) in the first frame of an input video. At this time, any corner detection algorithm can be used, for example, Harris corner detection algorithm [5], scale invariant feature transform (SIFT) algorithm [6], machine learning (machine learni...

Abstract

A detection and tracking device for moving target based on movement camera comprises a characteristic detection unit, finding characteristic point in a first frame of inputted video frequency; characteristic tracking unit, tracking characteristic point found by characteristic detection unit in following frame; latent movement detection unit, finding latent movement point from characteristic point tracked by characteristic tracking unit; movement analysis unit, determining movement point from latent movement point found by latent movement detection unit; target tracking unit, tracking movement target area from inputted video frequency according to given initial position. The inventive movement target detection and tracking system, device and method provide movement target position for 3A imaging at moving platform.

Description

technical field [0001] The present invention relates to a system, device and method for moving target detection and tracking, more specifically, to a system, device and method for moving target detection and tracking based on a moving camera. Background technique [0002] Motion detection and tracking is the most important technology in the field of computer vision, which includes imaging, image capture and image analysis. [0003] In the prior art, motion detection and tracking technologies may include the following methods: [0004] Based on extra hardware (Extra-Hardware) method [1]. In this approach, additional hardware such as infrared (IR), ultrasound, or stereo vision is utilized for motion detection. [0005] method based on image stitching. In this approach, different graphs are stitched into a panoramic image as the background for motion detection. [0006] Background Estimation Methods [2]. In this method, a fixed camera is used to estimate the background usi...
