【摘要】:運(yùn)用三維激光掃描技術(shù)獲得博物館內(nèi)部點(diǎn)云,并在此基礎(chǔ)上用3ds Max建立博物館三維模型、進(jìn)行材質(zhì)貼圖、燈光、攝像機(jī)和烘焙等工作,隨后將模型導(dǎo)入VRP實(shí)現(xiàn)交互式虛擬博物館系統(tǒng)的開發(fā)。館藏文物用手持式非接觸三維激光掃描儀進(jìn)行掃描并加工處理后得到真實(shí)的三維數(shù)字文物模型。為保證效率和效果,利用LOD算法對(duì)建立的復(fù)雜模型進(jìn)行簡(jiǎn)化。所設(shè)計(jì)的虛擬漫游場(chǎng)景,用戶不僅可身臨其境從多個(gè)視角觀察整個(gè)場(chǎng)景,并可通過(guò)鍵盤、鼠標(biāo)和距離觸發(fā)觀賞博物館中的文物,實(shí)現(xiàn)了虛擬場(chǎng)景的人機(jī)交互控制。系統(tǒng)交互性良好,沉浸感強(qiáng),可多角度、多種方式、多人稱自主漫游博物館并可近距離觀察研究館藏文物。
[Abstract]:The 3D laser scanning technology is used to obtain the point cloud inside the museum, and on this basis, 3ds Max is used to build a 3D model of the museum, which includes material mapping, lighting, video camera, baking and so on. Then the model is imported into VRP to realize the development of interactive virtual museum system. A real 3D digital cultural relic model was obtained by scanning and processing with a hand-held non-contact three-dimensional laser scanner. In order to ensure the efficiency and effect, the LOD algorithm is used to simplify the complex model. In the designed virtual roaming scene, the user can not only observe the whole scene from multiple perspectives, but also realize the human-computer interaction control of the virtual scene through keyboard, mouse and distance trigger to watch the cultural relics in the museum. The system has good interaction, strong immersion, can be multi-angle, various ways, many people call their own roaming museum and close observation of the collection of cultural relics.
