This proposal is to request the funding for a 3D laser scanner together with its control computer and one educational license of the associated data processing software.  The laser scanner is used to collect dense sets of data points (point clouds) from the surface of a physical object.  The scanned point clouds are needed to support the proposed research program aiming at developing advanced computer-aided design (CAD) and geometric modeling technologies.  Although the existing CAD technologies have been widely used in practice, they do not completely meet the designers' demand for accurate modeling of the desired product geometry and more importantly, their constant demand for facilitating human creativity in the CAD environment.  To enable the accurate model creation and mimic the human cognitive design process, a point-based geometric modeling scheme based on the scanned point cloud is proposed.  The development will lead the way in revolutionizing the CAD design process, resulting in superior product designs and greatly reduced design cycle times.The proposed research program supported by the requested laser scanning equipment is unique and directed at major advancement in the existing CAD technologies.  This advanced research initiative will put the University of British Columbia (UBC) as one of the world's leading institutions in CAD research.  Canadian industries will benefit significantly from the developed technologies and be able to design better and functionally enhanced products much more effectively.  Development of the prospective technologies will involve considerable training to the graduate students.  They will be trained in the latest 3D scanning technologies and obtain skills that are in great demand in industry as well as in many applied fields such as geology and medical image processing.  The laser scanner will also enable the establishment of a novel Rapid Product Development research facility, valued over $250,000.  For this planned networked facility, the high-priced rapid prototyping machine has already been acquired and available at UBC Department of Mechanical Engineering.

这项提议是申请资助一台3D激光扫描仪及其控制计算机和一份相关数据处理软件的教育许可证。激光扫描仪用于从物理对象的表面收集密集的数据点(点云)集。扫描的点云是支持拟议的旨在开发先进的计算机辅助设计(CAD)和几何建模技术的研究计划。*尽管现有的CAD技术已在实践中得到广泛应用，但它们不能完全满足设计师对所需产品几何形状的准确建模的需求，更重要的是，为了在CAD环境中实现精确的模型创建和模拟人类的认知设计过程，提出了一种基于扫描点云的基于点的几何建模方案。该开发将引领CAD设计过程的革命性发展，这一先进的研究计划将使不列颠哥伦比亚大学(UBC)成为世界领先的CAD研究机构之一。加拿大各行业将从所开发的技术中受益匪浅，能够更有效地设计出更好、功能更强的产品。未来技术的开发将涉及对研究生进行大量培训。他们将接受最新的3D扫描技术培训，并获得在工业以及地质学和医学图像处理等许多应用领域都非常需要的技能。激光扫描仪还将使建立一个新的快速产品开发研究机构，价值超过25万美元。对于这个计划中的联网设施，高价的快速成型机已经被收购，并在UBC机械工程部可用。
