Gdi uses three coordinate spaces : world, page, and device
Gdi +使用三個坐標空間:世界、頁面和設備。If we assume that the display device has 96 dots per inch in the horizontal direction and 96 dots per inch in the vertical direction, the endpoints of the line in the preceding example have the following coordinates in the three coordinate spaces
如果我們假定顯示設備在水平方向和垂直方向每英寸都有96個點,則上例中直線的終結點在三個坐標空間中分別具有以下坐標:By using it, the section mapping drawings of multi - types & complex pipeline system can be automatically generated through the entity crossing operation. this method composes of the following three key steps. in the first, different graphic entities are identified from the complex pipelines drawing in terms of the layer information they owned, then the correspondent information is to be encapsulated to keep the spatial data completeness of the graphic symbols
該方法通過管線系統設計圖中的圖形實體的分層處理與信息封裝,首先實現了復雜管線實體的自動識別並確保了圖形實體具有對應管線實體對象的完備空間信息;在此基礎上,根據用戶給出的任意位置截切線,構造隱式描述的截切面並與隱式描述的管線實體進行求交運算;最後通過對求交結果的坐標變換,生成能夠直觀反映出多類型復雜管線系統空間分佈信息的截切面映射圖。Compared with currently fire control system, apsse has such characteristic as : highly precision, complex construction, high technique, etc. so this thesis expatiated in detail on the measuring theory of apsse, emphases on the discussion of system error and random error of apsse, deduced the three axis error of apsse usign the coordination transformation methods, provided the applying base for the measuring error equation of apsse. in this paper, we emphases on expatiating the basic theory of usign space coordination transformation in the measuring error equation of apsse
因此,論文採用了空間坐標變換方法分析機載光電跟蹤測量設備在對目標進行測量、定位時空間坐標轉換關系,推導出從中心地平坐標繫到目標坐標系的變換矩陣,在此基礎上首先建立機載光電跟蹤測量設備的無測量誤差的位置傳遞方程和機載光電跟蹤測量設備的含有測量誤差的位置傳遞方程,為利用蒙特卡洛法分析機載光電跟蹤測量設備的測量誤差奠定了理論基礎。Including usign coordinate transformation method to deduce the uniform coordinate from the object coordinate to the photo coordinate, then setup the measuring error equation of apsse, this established the theory ground of usign the mont carlo method to analysis the error of apsse. there are errors from every tache of coordinate transform
由於建立機載光電跟蹤測量設備的測量誤差的位置傳遞方程是基於空間坐標變換的基礎上,從中心地平坐標繫到目標坐標系的變換涉及到幾十個環節,而每個環節都有誤差,其誤差的性質和大小直接影響對目標的定位測量。The paper has made detailed observation by the existing apparatus and the field observation stations. based on the image and the vector database of the yutian oasis, the study has obtained the precise coordinates of investigation points by gps technique, and overlapped them with the images. after classifying the images with the maximum likelihood supervised classification method, we import the result into cis software, and analyze the yutian oasis changes about land cover " s quantity, quality and spatial position from 1976 to 2001
本文利用現有儀器設備和野外觀測網站進行詳細觀測,在建立於田綠洲圖像庫和矢量數據庫的基礎上,運用gps技術取得野外考察樣點的精確坐標並與研究區各時期影像疊加,對影像進行了最大似然法監督分類,並將分類結果轉入gis軟體處理,全面分析了1976年至2001年該綠洲的土地覆蓋類型數量、質量與空間上的變化。Depth is specified in world space for vertex fog, and in either device space 0. 0, 1. 0 or world space for pixel fog
對于頂點霧化,在世界坐標空間指定深度;對于像素霧化,在設備坐標空間[ 0 . 0 , 1 . 0 ]或世界坐標空間指定深度。For pixel fog, these values are in device space when the system uses z for fog calculations, or in world space when the system uses eye - relative fog w - fog
對于像素霧化,如果系統使用z進行霧化計算,則以上值在設備坐標空間中;如果系統使用目相關霧化( w霧化) ,則以上值在世界坐標空間中。In the calibrating process, complicated measurement is avoided and the calibration is fast and easy to carry out, which simplifies the calibrating procedure. the experiment results show that the space measurement accuracy is better than 0. 15mm
這種參數分離法避免了標定過程中對空間點坐標的測量過程,不需要復雜精密的測量設備,計算速度快,試驗表明傳感器的精度達到0 . 15mm 。分享友人
