【摘要】:增強(qiáng)現(xiàn)實(shí)可實(shí)現(xiàn)真實(shí)場景與計(jì)算機(jī)虛擬信息的融合.研究了基于標(biāo)志的增強(qiáng)現(xiàn)實(shí)技術(shù),采用齊次變換實(shí)現(xiàn)基于標(biāo)志的增強(qiáng)現(xiàn)實(shí)三維注冊關(guān)鍵技術(shù),改進(jìn)了坐標(biāo)齊次變換支持多標(biāo)志識別,可同時對多個三維虛擬模型進(jìn)行平移、旋轉(zhuǎn)、縮放的剛體變換,實(shí)現(xiàn)虛擬物體的全方位操作.以古生物魔法書作為實(shí)例,展現(xiàn)了增強(qiáng)現(xiàn)實(shí)技術(shù)在教學(xué)中的應(yīng)用優(yōu)勢,探討了其在教育中的應(yīng)用方式、條件需求和關(guān)鍵技術(shù),實(shí)例結(jié)果顯示增強(qiáng)現(xiàn)實(shí)進(jìn)入教學(xué)領(lǐng)域可行性.
[Abstract]:Augmented reality can realize the fusion of real scene and computer virtual information. The technology of augmented reality based on sign is studied, the key technology of 3D registration based on sign is realized by homogeneous transformation, the coordinate homogeneous transformation is improved to support multi-mark recognition, and several 3D virtual models can be translated at the same time. Rotation, scaling of the rigid body transformation, to achieve the full-directional operation of virtual objects. Taking the ancient biological magic book as an example, this paper shows the application advantage of augmented reality technology in teaching, and discusses its application mode, condition demand and key technology in education. The result shows that augmented reality is feasible to enter the teaching field.
