增强现实系统中自适应光照调节技术研究

增强现实系统中要解决的关键问题之一是光照一致性,它是确保虚拟物体表面光照效果真实感,使其能和真实环境很好的融合的关键.系统中必须配合真实光源的情况,在虚拟物体上制作出明暗、反射、阴影等光照效果.通过对光照一致性问题以及由光照引起的相关问题的研究,引出了光照模型理论,推导了基于镜面反射的光照检测方法,研发了一个自适应的光照调节系统,较好解决了虚实场景的光照一致性,并且成功地将自适应的光照调节系统应用在基于投影的AR系统中,得到了良好的视觉效果.     

Office Automation System for Enterprise Based-on .NET

A system—Asynchronous JavaScript and XML(AJAX)and a Model-View-Controller(MVC)pattern algorithm were proposed for design and implementation of an office automation(OA)system.Adopting the.NET framework as development platform,the system modifies the classic MVC pattern,induces AJAX in the ASP.NET 2.0,and includes several modules,namely login,messaging,notice board,personal work,research management,document management,personnel information and maintenance.We discussed the overall structure of the system,funct...
