d data volume 中文意思是什麼

d data volume 解釋
三維數據體
  • d :
  • data : n 1 資料，材料〈此詞系 datum 的復數。但 datum 罕用，一般即以 data 作為集合詞，在口語中往往用單數...
  • volume : n. 1. 卷，冊；書籍；【歷史】書卷，卷軸。2. 〈常 pl. 〉大塊，大量，許多。3. 體積；容積；分量，額；【物、樂】音量；強度，響度。
  1. The traditional algorithm of volume rendering is ray - casting, not a proper algorithm for the large 3 - d seismic data, referring some improved method and considering the characteristic of seismic data, a new fast ray - casting algorithm of oriented image space and negative - view transform was brought forward. as a result, this algorithm excels the traditional obviously by speed with image quality in experiment

    體繪制的傳統演算法是光線投射法，由於地震數據量大而繪制速度太慢，本文在借鑒一些改進演算法的基礎上，結合地震數據的特點，提出了一種基於圖像空間的逆視變換的加速光線投射演算法，實驗結果表明該演算法在保證相同圖像效果的同時，具有明顯的速度優勢。
  2. Typical computer generated holography ( cgh ) and hologram synthesis that simulate typically optical holography need to compute a huge 2 - d holographic fringe, or to lose some 3 - d information and resolution to reduce data. the first real - time display of holographic images was reported in 1990 by the mit spatial imaging group. but this is still an open problem because view angle of holographic images, volume and speed of transmit are limited

    傳統的研究集中在計算機生成全息圖（ computer - generatedholography ，簡稱cgh ）和全息圖綜合的方法上，採用模擬光全息的物理方法，從而導致數據量龐大，無法在現有硬體上完成實時處理，或者靠損失部分三維信息和解析度以減少數據量，但失去了真三維顯示的效果。
  3. 2. the microcomputer - based greenhouse monitoring & controlling system has been developed around an atmel microcontroller which is reinforce by multiplex a / d sampling module ; large volume data on - line storage module ; real - time clock module ; keyboard & display man - machine interaction module ; system monitoring module and communication interface module and so on

    溫室微機測控系統的設計以美國atmel公司的微控制器為核心，擴展了多路a d採集子模塊、大容量數據在線存儲子模塊、實時時鐘子模塊、鍵盤顯示人機對話子模塊、系統監視子模塊、現場總線系統和上下位計算機通訊子模塊等等。
