【正文】 存檔日期: 存檔編號(hào): 江蘇 師 范 大 學(xué) 本科生畢業(yè)論文(設(shè)計(jì)) 論 文 題 目: 不同坐標(biāo)系的轉(zhuǎn)換及其程序設(shè)計(jì) 姓 名: 陳航 學(xué) 號(hào): 09271029 院 系: 測(cè)繪學(xué)院 專(zhuān) 業(yè): 測(cè)繪工程 班 級(jí): 09 測(cè) 11 指 導(dǎo) 教 師: 王愛(ài)生 江蘇師范大學(xué)教務(wù)處印制 I 摘 要 隨著空間技術(shù)的發(fā)展,全球一體化的形成,越來(lái)越多的要求全球測(cè)繪資料形成統(tǒng)一規(guī)范,尤其是坐標(biāo)系統(tǒng)的統(tǒng)一。由于各測(cè)量單位工作目的不同,所選擇的橢球參考系也會(huì)有所不同,出現(xiàn)了許多不同形式的坐標(biāo)系,例如 WGS84坐標(biāo)系、國(guó)家 80 坐標(biāo)系、北 京 54 坐標(biāo)系、獨(dú)立地方坐標(biāo)及各種坐標(biāo)。在同一坐標(biāo)系下坐標(biāo)的表示方式又有空間直角坐標(biāo)、大地坐標(biāo)、平面坐標(biāo)。根據(jù)不同的測(cè)繪需求,需要將不同的坐標(biāo)系下的坐標(biāo)進(jìn)行相互轉(zhuǎn)換,在這些坐標(biāo)轉(zhuǎn)換的過(guò)程中既會(huì)運(yùn)用到同一坐標(biāo)系下的坐標(biāo)轉(zhuǎn)換模型,又會(huì)用到不同參考系下各坐標(biāo)系間的坐標(biāo)轉(zhuǎn)換模型。 首先 本文介紹大地測(cè)量學(xué)坐標(biāo)的相關(guān)知識(shí), 接著介紹了與坐標(biāo)轉(zhuǎn)換相關(guān)的知識(shí)以及坐標(biāo)轉(zhuǎn)換模型 (包括 同一坐標(biāo)系下的坐標(biāo)轉(zhuǎn)換模型 和 不同參考系下各坐標(biāo)系間的坐標(biāo)轉(zhuǎn)換模型 ),并 利用 vb 語(yǔ)言實(shí)現(xiàn)坐標(biāo)轉(zhuǎn)換的過(guò)程。 關(guān)鍵詞: 地球橢球 , 坐標(biāo)系,轉(zhuǎn)換模型 , 坐 標(biāo)轉(zhuǎn)換 II Abstract Along with the development of space technology, the formation of global integration, more and more requirements of surveying and mapping material form a unified global standard, especially the unity of the coordinate system. Because each measurement unit work purpose is different, choose the frame of reference ellipsoid would differ, the emergence of many different forms of coordinate system, such as WGS84 coordinate system, the state 80 coordinate system, Beijing 54 coordinate system, independent local coordinate system and various kinds of urban construction coordinates. In the same coordinate system of representation and coordinate space rightangle coordinate, coordinate, coordinate the earth plane. According to the different needs of surveying and mapping, need different coordinate transformation coordinate system, in which the process of coordinate transformation can use to the same coordinate system coordinate transformation model, and will use different reference frame, the coordinate transformation between the coordinate system model. First of all this paper introduces the geodetic coordinates of relevant knowledge, then introduce the knowledge of coordinate transformation and coordinate transformation model(including the same coordinate system coordinate transformation model and different reference frame, the coordinate transformation between the coordinate system model), and the use of vb language realization of coordinate transformation process. Key words: the earth ellipsoid, coordinate system, transformation model, coordinate transformation III 摘 要 ...............................................................................................................................
