Electronic Image Stabilizing Method Research In Omni-directional Camera System

The article mainly proposes a method for electronic image stabilizing which applies in omni-directional vision system.The omni- directional cemara system is equiped with 360 cemara angle.Accounting for that the omni-directional vision sequence is not suitale for being observed,we have to split the omni-directional vision sequence into original image sequences of physical reality,and further study on its image stabilizing .Implementation method is deeply researched on the solution algorithm of omni- directional vison image and stabilizing image in this paper,and a iamge stabilizing method of omni-directional camera system is proposed which is based on the electronic stabilizing algorithm of gray projection.In order to improve the fastness of digital image stabilization, make the algorithm simply to realize, and reduce time complexity and redundancy of the algorithm to minimum, a fast electronic image stabilization method is proposed in this paper, and the correspomding preprocessing methods have been adopted,this algorithm can accurately process images,thus the applicable range of gray projection algorithm can be extended.With the help of OpenCV platform recently rising to achieve. The current rise OpenCV is Intel? Open Source Computer Vision Library, it incorporates a lot of universal algorithm for image processing and computer vision. Experiments were made using image sequences captured by car-carried camera equipment, results show that the proposed algorithm has trait of high real-time, fast, and so on.Generally speaking, the extraction ability of revolving displacement based on gray projection algorithm is ordinary. This article rests on this factor, make a improvement of ordinary gray projection algorithm. As a result of panoram photograph system is a one kind of 360 degree imaging system, even a small change of peripheral environment can lead to a wide range displacement of panoramic picture element, then affects the panoram photograph system's steady elephant precision. This article rests on an above pairs factor, designed a image stabilizing method of omni-directional which is based on the electronic stabilizing algorithm of gray projection., while has guaranteed timely, enormous enhancement panoram photograph system's steady elephant precision.This system is composed of omni-directional devices,CCD,image gathering card and computer and the software programming is implemented through VC++ based on DiretShow platform .According to the analysis results,this mathod is a reasonable one of electronic image stabilizing for omni-directional camera system ,which is characteristic of quickspeed and acurracy.
