The Technology Of Multiple Cameras Panoramic Image Mosaicing Real-time Video Processing

Nowadays,with the rapid development of digital technology and information technology,people pay more attention to image acquisition device,but also have higher requirements for the resolution of the images and screen graph.a single camera alone may not be able to meet the needs of the consumers.Depend on a single camera to capture is limited,if you want to get high resolution images,a single camera can only be done by adjusting the focal length,but the problem has emerged,causing reduction of image,bringing bad visual effect.Therefore,the image can be collected by a plurality of cameras,and the mosaic of panoramic images can be completed.The real-time panoramic view real-time monitoring system is one of the main application of multi-camera real-time splicing technology,it can well solve these problems that the disadvantages of traditional monitoring system mainly is the multiple points of scene monitoring,relatively messy.And it has good performance in the field of security monitoring market(communication,shops,supermarkets,wharf road,etc).The paper mainly discusses the multi-camera panoramic image mosaicing of real-time video processing technology research,and introduce multi-camera real-time panoramic image stitching system architecture.Firstly,a brief introduction to multiple camera view image splicing of real-time video processing technology research background and research status,and basic theoretical knowledge of many cameras panoramic image mosaicing related.Secondly,propose more cameras panoramic image in real time.Splicing system overall scheme and architecture,have a brief description of the function of each part.Then,in view of the cameras in the panoramic image mosaicing two key links,introduce the image registration and image fusion,in detail.The common methods of image registration and image fusion are listed,and the suitable method is used to complete the panoramic image mosaic.Image registration part analysis SIFT feature matching algorithm principle and implementation of image fusion part adopts multiresolution fusion method,to ensure the quality of image fusion.Meanwhile,considering the multiple cameras near thelight intensity of different color effects,image color correction method was proposed,multi camera panoramic image color correction,ensure panorama effect.Finally,based on the multi-camera panoramic image mosaic system for real-time testing,test results show that this design scheme can well achieve panoramic image stitching,providing a certain reference value for future research and development of multi camera real-time panoramic image mosaic system.
