发布时间:2018-08-20 08:19
【摘要】:增强现实可实现真实场景与计算机虚拟信息的融合.研究了基于标志的增强现实技术,采用齐次变换实现基于标志的增强现实三维注册关键技术,改进了坐标齐次变换支持多标志识别,可同时对多个三维虚拟模型进行平移、旋转、缩放的刚体变换,实现虚拟物体的全方位操作.以古生物魔法书作为实例,展现了增强现实技术在教学中的应用优势,探讨了其在教育中的应用方式、条件需求和关键技术,实例结果显示增强现实进入教学领域可行性.
[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.
