中文拼音 [zhàzhuàngtú]
柵狀圖
英文
fence diagram-
In measurement of three - dimensional object shapes using projected grating method, the height of each point of the measured object is obtained through the processing and analysis of the stripe images
採用投影柵線法進行三維形狀檢測，主要通過對條紋圖像的處理，從中獲取被測物體各點的高度分佈。In the first place, the study processed data of remote sensing and non - remote sensing to be digital, vector, raster and imagery geocode, established geographic database of soil erosion, and calculated elements " pixel maps of soil erosion. secondly, by using model builder of arcview to establish dynamic survey model of soil losses in longchuan river drainage basin. at last, to obtain maps of status & the forecast maps for soil conservation
首先通過遙感與非遙感資料的數字化、矢柵化及圖形圖像地理配準，建立了水土流失地理數據庫，並運算出水土流失各因子像元圖；在此基礎上，憑借arcview子模塊modelbuilder的支撐，建立龍川江流域水土流失動態監測模型；最後運行該模型獲取水土流失現狀圖和防治預報圖等結果圖件，完成了研究區1998 、 1999年水土流失定量遙感監測任務。The fresnel and franhufer diffraction patterns, of regular shapes screen such as slits, rectangular apertures, circle apertures, discs, triangle apertures, ronchi gratings, and some irregular shapes screen, are observed in the different propagation distance. this clearly gives the relation and difference of the two diffraction patterns
具體分析了規則形狀如單縫、矩孔、圓孔、圓盤、三角孔、黑白光柵及一些不規則形狀等孔徑的菲涅耳衍射和夫瑯禾費衍射圖樣強度分佈，為深入理解菲涅耳衍射和夫瑯禾費衍射及其內在聯系與區別提供了理論依據。Watershed land use condition was updated swiftly, watershed land use status map was made, through vector - grid overlap of land use status map and doq, distillation characteristic data and updating data. 5
通過土地利用現狀圖（ dtl ）與doq矢柵疊加，提取特徵數據並更新數據的方法，對流域土地利用進行快速更新，完成流域土地利用現狀圖的製作。The complex situation of flight requests that the graphics display of cockpit must be dynamic, real - time and legible. but in the raster graphic display system, scale lines and character will be distorted seriously owe to the limited screen resolution in the case of deflection, which affect the display quality. the thesis based on the research of the last graduate student improves the graphics creating arithmetic more and puts forward more effective arithmetic on scale lines and character for high display quality
由於飛行狀態復雜，要求座艙內畫面顯示動態、實時、清晰。而硬體系統採用的是光柵圖形顯示，字元和刻度線的旋轉受屏幕解析度的限制存在著鋸齒走樣現象，影響顯示效果。本文在上一屆研究生研究的基礎上，在圖形生成演算法上加以進一步改進，重點在刻度線、字元的反走樣處理上，研究出了更合理的演算法，提高了圖形顯示質量。The algorithm takes advantage of the merits of the watermarks both in low frequency and high frequency and can embed more information with less distortion. experimental results show the algorithm is robust to many common image operations. as for the vector map data, an uniform model of embeding watermark for vector maps and raster maps is proposed after current trend of research and watermarking methods of 3 - d vector images are summarized, primary study results show the model is effective and promising to further research
目前該問題在國內外都還處于探索階段，作者在分析了國內外三維矢量水印的研究狀況、研究方法后，提出了將矢量數據中的部分信息轉化為柵格形式后再嵌入水印的方法，該方法使地圖柵格數據和矢量數據在嵌入水印時能夠使用統一模型，初步的實驗結果表明該方法為二維地圖矢量數據的水印嵌入開辟了一種新途徑。分享友人
