【摘要】：海洋科學(xué),水利經(jīng)濟(jì)以及相關(guān)產(chǎn)業(yè)的發(fā)展,使得水下監(jiān)測(cè)設(shè)備的重要性日益提高。三維實(shí)時(shí)成像聲納具備實(shí)時(shí)性強(qiáng),圖像清晰直觀等優(yōu)點(diǎn),因此,研究三維實(shí)時(shí)成像聲納系統(tǒng)具有重要的工程實(shí)用價(jià)值。作為三維實(shí)時(shí)成像聲納系統(tǒng)的重要組成部分,本論文研究并設(shè)計(jì)了三維聲納實(shí)時(shí)成像系統(tǒng)軟件,軟件包含聲納數(shù)據(jù)的數(shù)據(jù)處理和可視化算法。三維聲納實(shí)時(shí)成像系統(tǒng)軟件根據(jù)聲納數(shù)據(jù)流走向可以分為接收模塊,預(yù)處理模塊,算法模塊,顯示模塊和參數(shù)控制模塊。模塊間用信號(hào)量進(jìn)行數(shù)據(jù)同步和緩存共享,減少了軟件內(nèi)存的占用,提高了軟件運(yùn)行效率。軟件利用VTK的流水線機(jī)制實(shí)現(xiàn)了聲納數(shù)據(jù)的三維顯示。軟件設(shè)計(jì)了緩沖區(qū),防止網(wǎng)絡(luò)波動(dòng)和運(yùn)算速度造成的圖像抖動(dòng),提高了顯示質(zhì)量。軟件采用模塊化的設(shè)計(jì)方法,結(jié)合多線程技術(shù),為代碼的擴(kuò)展和功能的添加提供了便利,減少了代碼的耦合性,提高了代碼的可擴(kuò)展性和可維護(hù)性。此外,本論文研究并設(shè)計(jì)了聲納降噪算法和聲納分割算法,降低原始數(shù)據(jù)噪聲,同時(shí)實(shí)現(xiàn)固定區(qū)域的交互式圖像分割。在算法實(shí)現(xiàn)的基礎(chǔ)上,本軟件的設(shè)計(jì)充分考慮了成像實(shí)時(shí)性的要求,優(yōu)化算法提高了運(yùn)行效率,并在測(cè)試中實(shí)現(xiàn)了算法的預(yù)期,達(dá)到了實(shí)時(shí)成像的要求。
[Abstract]:With the development of marine science, water economy and related industries, underwater monitoring equipment is becoming more and more important. Three-dimensional real-time imaging sonar has the advantages of real-time, clear and intuitive image, so the study of three-dimensional real-time imaging sonar system has important engineering practical value. As an important part of 3D real-time imaging sonar system, the software of 3D real-time imaging system is studied and designed in this paper. The software includes the data processing and visualization algorithm of sonar data. According to the direction of sonar data flow, the software of 3D sonar real-time imaging system can be divided into receiving module, preprocessing module, algorithm module, display module and parameter control module. The semaphore is used for data synchronization and cache sharing among modules, which reduces the use of software memory and improves the efficiency of software operation. The software realizes the three-dimensional display of sonar data by using the pipeline mechanism of VTK. The buffer is designed to prevent the image jitter caused by network fluctuation and operation speed, and the display quality is improved. The software adopts the modular design method and the multi-thread technology, which provides convenience for the code extension and function addition, reduces the code coupling, and improves the extensibility and maintainability of the code. In addition, this paper studies and designs sonar de-noising algorithm and sonar segmentation algorithm to reduce the original data noise and achieve interactive image segmentation in fixed region. On the basis of the realization of the algorithm, the software design fully considers the requirement of real-time imaging, optimizes the algorithm to improve the running efficiency, and realizes the expectation of the algorithm in the test, which meets the requirements of real-time imaging.
