【摘要】：运用三维激光扫描技术获得博物馆内部点云,并在此基础上用3ds Max建立博物馆三维模型、进行材质贴图、灯光、摄像机和烘焙等工作,随后将模型导入VRP实现交互式虚拟博物馆系统的开发。馆藏文物用手持式非接触三维激光扫描仪进行扫描并加工处理后得到真实的三维数字文物模型。为保证效率和效果,利用LOD算法对建立的复杂模型进行简化。所设计的虚拟漫游场景,用户不仅可身临其境从多个视角观察整个场景,并可通过键盘、鼠标和距离触发观赏博物馆中的文物,实现了虚拟场景的人机交互控制。系统交互性良好,沉浸感强,可多角度、多种方式、多人称自主漫游博物馆并可近距离观察研究馆藏文物。
[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.
