【摘要】：我國是一個濱海大國,擁有豐富的海洋資源。隨著國家海洋強國戰(zhàn)略的推進以及海底聲學探測技術(shù)的飛速發(fā)展,海洋管理、科研和生產(chǎn)單位獲得了大量的海底聲學探測成果數(shù)據(jù),但這些數(shù)據(jù)缺乏直觀、形象的表達。有效的表達這些數(shù)據(jù),能為科學研究和工程實踐提供極大的便利。本文面向海底聲學探測,研究了三維可視化技術(shù),實現(xiàn)了海底聲學探測成果數(shù)據(jù)綜合可視化系統(tǒng)。進行的開拓性和探索性工作如下:1.提出利用GPU的紋理緩沖區(qū)解決側(cè)掃聲吶影像和多波束測深數(shù)據(jù)分辨率不一致引起的紋理貼圖問題。該方法使顯存每次加載大量的數(shù)據(jù),避免了數(shù)據(jù)在內(nèi)存和顯存中反復傳輸帶來的延遲。2.研究了沉積、侵蝕現(xiàn)象的地質(zhì)體建模�；谒迫庵�,提出了沉積、侵蝕地層的判別方法以及四面體剖分方法,利用稀疏的地層解譯數(shù)據(jù)構(gòu)建三維地質(zhì)體模型。3.實現(xiàn)了海底聲學探測成果數(shù)據(jù)三維綜合可視化系統(tǒng)。該系統(tǒng)能夠在同一視圖下綜合顯示多波束測深數(shù)據(jù)、側(cè)掃聲吶影像和淺地層剖面數(shù)據(jù)�；诒疚难芯砍晒_發(fā)的海底聲學探測數(shù)據(jù)綜合可視化系統(tǒng)在海底穩(wěn)定性評價中得到了應用,實踐證明該系統(tǒng)能滿足數(shù)據(jù)綜合可視化的需求。
[Abstract]:China is a coastal country with abundant marine resources. With the development of the strategy of national ocean power and the rapid development of seabed acoustic detection technology, ocean management, Scientific research and production units have obtained a large amount of underwater acoustic survey data, but these data are not directly and vividly expressed. It can provide great convenience for scientific research and engineering practice. A comprehensive visualization system for underwater acoustic exploration data is implemented. The pioneering and exploratory work is as follows: 1. A method of using GPU texture buffer to solve the problem of inconsistent resolution between sidescan sonar images and multi-beam bathymetric data is proposed. This method enables the display memory to load a large amount of data at a time. The delay caused by the repeated transmission of data in memory and display memory is avoided. The geological modeling of sedimentation and erosion is studied. Based on the triangular prism, a method of distinguishing sedimentary and erosive strata and a method of tetrahedron division are proposed. A 3D geological model .3.Using sparse stratigraphic interpretation data, a 3D integrated visualization system for underwater acoustic exploration data is implemented. The system can display multi-beam bathymetric data in the same view. Based on the research results of this paper, the integrated visualization system for underwater acoustic detection data has been applied to the evaluation of submarine stability. The practice shows that the system can meet the needs of comprehensive visualization of data.
