Study on the capture of the three - dimensional information in computational holography 計(jì)算全息三維信息獲取的研究
When a three - dimensional scene is projected to a two - dimensional image , a lot of three - dimensional information was lost , and the goal of the three - dimensional scenes restoration is to recover the lost information 當(dāng)三維場景投影成二維圖像時(shí),許多三維信息就會被丟失,三維重建的目的就是要恢復(fù)這些丟失的信息。
High technological it pattern composing three - dimensional information management network of cross - industries , the management of headquarters to napa stores and shop operation are completely control by computer 技的it模式構(gòu)成跨行業(yè)的立本信息管理網(wǎng)絡(luò),連鎖總部對加盟店的管理、各加盟店店面營運(yùn)全部由計(jì)算機(jī)管理實(shí)現(xiàn)。

Optical flow field contains not only the moving information of the object , but also three - dimensional information . this paper integrates the inter - frame difference and optical flow methods . the method of inter - frame difference is used to separate moving area from the whole image 本文將二者相結(jié)合,運(yùn)動目標(biāo)的第一步檢測由幀間差值法完成,同時(shí)運(yùn)用數(shù)學(xué)形態(tài)學(xué)方法對差值圖像進(jìn)行過濾和排查,精確提取出多運(yùn)動目標(biāo)的運(yùn)動區(qū)域。
Interferometric synthetic aperture sonar ( insas ) provides a means of obtaining 3 - dimensional images of scene . three - dimensional information is derived from the phase difference between two ( or several ) complex images of sas taken from separate receiving array across the track 干涉合成孔徑聲納( insas )是在合成孔徑聲納( sas )基礎(chǔ)上垂直航跡方向增加一副(或多副)接收基陣,通過比相測高的方法得到場景的高度信息,從而得到場景的三維圖象。
Landslide visualization is one of the most effective methods to reproduce and analysis synthetically the three - dimensional information of landslide body in real time . the application of visualization on landslide will greatly prompt the development of landslide and bring to the enormous benefits for the society , the economy and ecosystem system 滑坡可視化技術(shù)是快速、適時(shí)地再現(xiàn)滑坡體三維信息及綜合分析的有效途徑,它將極大地促進(jìn)滑坡研究的發(fā)展,為社會、經(jīng)濟(jì)和生態(tài)系統(tǒng)帶來顯著利益。
It fully utilize the high - performance computer hardware or software resources and all kinds of advanced sensors . main technology consists of real - time three - dimensional figure making technology , interactive multi - sensor technology and high - resolution show technology , etc . virtual reality technology can turn into the real - time , virtual environment with three - dimensional information 所謂虛擬現(xiàn)實(shí)技術(shù),就是充分利用高性能的計(jì)算機(jī)硬件與軟件資源及各類先進(jìn)的傳感器的一種集成技術(shù),其主要技術(shù)構(gòu)成為實(shí)時(shí)三維圖形生成的技術(shù)、多傳感交互技術(shù)以及高分辨率顯示技術(shù)等。
