摘要
工程设计中涉及大量的设计资料,设计资料的一部分是以工程曲线的形式存在。本文提出工程曲线的图片导入、图片校正、网格去除、图像细化和图像扫描等方法以实现工程曲线的数字化。进一步地,通过线性插值和抛物线插值方法实现曲线数据的检索与查询。
Engineering design revolves a lot of design data. Partial design data are described in the form of engineering curves. In the paper, an engineering curve is digitized through image import of the engineering curve, image correction, mesh deleting, image simplify and image scan. Furthermore, the linear interpolation and parabola interpolation are used to retrieve and query data.
