【摘要】 随着数字化技术的逐步普及,越来越多的形体通过3D扫描设备输入计算机,然后通过一系列操作转化为CAD模型。但由于价格、适用性、易用性等条件影响,现有的3D扫描设备不能满足许多用户的需求。本文集成线激光法扫描发与遮挡轮廓重构法,实现了一套简便、易用的3D光学扫描系统,充分利用不同特性的形体空间信息,生成可靠的数字模型。文中详细介绍了相关原理、系统集成方法,并提出了一种基于分片能量泛函的数据融合方法。最后给出了一个典型扫描实例,验证了本文方法的有效性。更多还原

【Abstract】 Freeform shape is usually designed by reverse engineering method thorough a 3D scanner,which is often expensive to most persons.The paper proposes a new scanning system combining shape from structured light and shape from silhouette,which can be implemented easily with low cost.It can increases the precision of shape from silhouette,and can correct the topological errors of shape from structured light.The design details are introduced,and a new data fusion strategy based a patch wise energy functional is proposed to integrate the information from the two scanning methods.A toy dog is used to test the new method,which is difficult to scan using other systems.The test results proof the validity of the new method.更多还原
