ROV平台全景摄像系统的研究
A Study on Panoramic Camera System of ROV Platform
摘要
Abstract
Unlike imaging in air,underwater panoramic imaging faces great challenges arising from water pressure and diminished light,necessitating special lens packaging and focused underwater illumination.The processing of underwater images from multiple channels necessitates adaptations to existing image processing algorithms to mitigate color cast,noisy points,and other imaging defects.And based on the hot research of panoramic video transmission,the underwater panoramic imaging system on the ROV platform holds great development potential.Based on the technical research of underwater panoramic photography,this paper first elaborates on the generation and transmission of underwater panoramic images and discusses two camera layouts:distributed and integrated,utilizing the remotely operated vehicle(ROV)platform as the carrier,through an analysis of camera hardware requirements.Subsequently,it introduces the creation of panoramic images from multiple channels of image data through a process involving image preprocessing,stitching,and fusion.Lastly,taking into account of remote video transmission through water boundaries,a self-adaptive multi-rate transmission scheme is presented,based on the stream division into slices(Tile stream)for panoramic videos.From the development of underwater panoramic technology,with the improvement of panoramic technologies such as lossless image stitching,iterative computing speed of image processors,image restoration,ultra bandwidth connection,and panoramic video transmission,ROV platform panoramic camera systems will be widely applied.关键词
