摘要本文围绕气泡的采集和如何数出气泡的个数进行了一番研究,课题难度偏难,虽说是数出小小的气泡,可内部却包含很多学问。
气泡采集对于军事方面尤其是潜艇具有重要意义,在日趋紧张的国际形势和我国对海洋权益的日趋扩张,气泡的研究前景非常广阔。
本课题首先需要利用光学摄像头捕捉气泡的轨迹,拍出优质的气泡画面。接着利用图像二值化处理把气泡和水进行图像分割,这当中就伴随着去噪和滤波等手段。再然后,便是对图像进行边缘检测,通过一系列技术,比如边缘连接从而润滑图片。从而正确数出气泡的个数。上面的技术可谓成熟已久。最后,也是本课题的创新之处,利用图像拼接技术,数出多幅图片的气泡个数,将多次出现的气泡排除掉。从而输出一段时间内气泡的总个数。19500

Title The design of underwater bubbles acquisition and processing system
Abstract
This paper focuses on the number of bubbles and how to collect the number of bubbles for a lot of research.This task is a little difficult.. Although it is a small number of bubbles, but it contains a lot of knowledge internally.
Bubble collection particularly important for the submarine military aspects. In the increasingly tense international situation and the increasing expansion of the country's maritime rights and interests, Researching bubbles are very bright prospects.
We first need to use an optical camera to capture the trajectory of the bubble for the picture quality. Then use the binary image to process water and bubbles for the image segmentation. Among these it will need to de-noising and filtering means.then we will using image edge to dectect the picture. Through a series of technical, such as using Edge Connector to smooth the edges of the picture to correctly count the number of bubbles. The above technique has long been described as mature. Finally, the content is the subject of innovation .That is counting the number of pieces of bubble picture and remove the bubbles repeated with the image stitching technology.Thus the total number of bubbles in the output period .
Keywords: bubbles Image binarization Edge Detection Image Stitching

1.1 背景及意义
随着中国的崛起和海洋权益的扩张。潜艇的作用越来越凸显出其重要性,由于潜艇在深海中航行时靠着蓄电池文持电量,因而需要时不时的浮出水面进行充电,为了增加潜艇的隐蔽性,于是AIP(Air Independent Propulsion)便成了当今世界上主流的动力装置。它通过一系列的动力系统,通过减少潜艇上浮的次数来摆脱潜艇对通气管的依赖。但正因为如此,舱室中的污染气体就会更多,大量的气泡给目标的暴露带来了巨大的隐患。因为这些污染气泡飘在海里使得潜艇所在海区的光学性质,声学性质发生了变化。这一变化自然会被各国的雷达和反潜艇装置所感知到。因而本课题研究气泡的个数对于海防大业具有深远的意义。 MATLAB水下气泡采集处理系统设计+文献综述:http://www.751com.cn/zidonghua/lunwen_11026.html
