摘　　要：本文尝试利用三维激光扫描数据——点云,实现在计算机辅助制图下完成佛龛展开示意图的方法。此方法借鉴并融合手工测绘时对佛龛曲面的展开结构、画法几何曲面展开法以及坐标控制法等,是考古绘图在龛壁曲面展开实践方法上的一个新尝试。本文同时探讨了手工展开龛曲面的可能性,并进行了两种方法之间的比较。This paper deals with the graphic solution method in unfolding drawings of arched niches using computer-aided drawings based on 3D laser scanning. This method refers to the combination of three methods-- manually unfolding drawings, a curved surface descriptive geometry approach, and a coordinated control method. The application of this technology is a new attempt in handling the problem of attaining accurate images from hard to access locations. This paper also discusses the feasibility of manually unfolding drawings and the differences between these methods.
