摘要
大幅面自由表面投影技术在展览展示、产品发布、虚拟仿真等领域得到了广泛的应用。在深入分析自由表面投影拼接应用案例以及国内外研究现状的基础上,提出了一种新型的适用于大幅面自由表面的投影拼接方法,所研究的关键技术包括相机校正、结构光编码、固定视角的投影几何校正等,在理论研究的基础上设计并实现了三维建筑模型投影系统。实验表明,所提出的方法能够满足建筑表面投影拼接的需求。
Abstract
Large-format arbitrary-surface projection technique has been widely applied in such fields as exhibition,re-lease of new product and virtual simulation etc.The applications and research status of the large-format arbitrary-surfaceprojection technique are analyzed.A novel large-format arbitrary-surface projection method is proposed,which includescamera calibration,structured light coding,geometry correction based on the observer view etc.The system structure andimplementation for the 3Darchitectural model projection is also described.Experimental results prove that the proposedmethod meets the requirements of architectural projection.
