Resultsl three - dimensional data of facial profile was accurate and the images were reconstructed with verisimilitude 結(jié)果:面部軟組織的三維數(shù)據(jù)的采集度高,生成的團(tuán)像逼真。
It is started with the specification requirement for the visual scene data base by navigation simulator , and adopts three - dimensional data structures to construct the visual scene data base model of navigation simulator 首先從航海模擬器對(duì)視景數(shù)據(jù)庫(kù)的技術(shù)要求入手,采上海海運(yùn)學(xué)院碩士學(xué)位論文用層次型與面向?qū)ο笙嘟Y(jié)合的三維數(shù)據(jù)結(jié)構(gòu),構(gòu)造了航海模擬器視景數(shù)據(jù)庫(kù)模型。
Only need to offer the three - dimensional data of the products , can process the model as mould . the model palm can examine appearance design , inspection structural design , avoid holding the risk of the mould directly , make the time of emerging of products advanced greatly 只需要提供產(chǎn)品的三維數(shù)據(jù),就可以加工出和模具一樣的模型。模型手板可以檢驗(yàn)外觀設(shè)計(jì),檢驗(yàn)結(jié)構(gòu)設(shè)計(jì),避免直接開(kāi)模具的風(fēng)險(xiǎn)性,使產(chǎn)品面世時(shí)間大大提前。
From domestic and international research situation , the research of virtual reality system focuses on hardware interface , algorithm describing and picture process , etc . there is not much study in transformation from two - dimensional data to three - dimensional data ; there is simple three - dimension show of the research of vrml more , combination with database supported few 從國(guó)內(nèi)外的研究現(xiàn)狀看,虛擬現(xiàn)實(shí)系統(tǒng)的研究主要集中在硬件接口、算法描述及圖像處理等方面,而對(duì)于傳統(tǒng)二維數(shù)據(jù)到三維圖像的轉(zhuǎn)換研究不多;對(duì)于vrml方面的研究也多以單純?nèi)S展示為主,少有與后臺(tái)數(shù)據(jù)庫(kù)的結(jié)合。
Renewal made of the mould , advanced high - speed machining center , with the high rotational speed , so high as to enter for the speed , high precision and high efficiency to replace profile modelling to mill , namely process and replace simulation to process with the data , from the three - dimensional data mould three - dimensional structure numerical control cnc form of the products , all appear with the data 模具制造的更新,先進(jìn)的高速加工中心,以高的轉(zhuǎn)速高的進(jìn)給速度高的精度和高的效率取代了仿形銑,即以數(shù)據(jù)加工取代模擬加工,從產(chǎn)品的三維數(shù)據(jù)模具三維結(jié)構(gòu)數(shù)控cnc程式,全部以數(shù)據(jù)顯現(xiàn)。
