摘要

为了实现非均匀有理B样条(NURBS)图形的激光雕刻,推导了显式有理多项式的NURBS表达式,并在此基础上研究了NURBS图形激光雕刻算法,然后在基于DSP/BIOS的实时嵌入式平台上实现了NURBS图形激光雕刻控制系统.实验结果表明,高性能嵌入式平台能够满足算法的空间和时间需求,实现复杂NURBS图形激光雕刻.

Abstract

In order to implement the laser marking of non-uniform rational B-spline(NURBS) images,the NURBS expression of an explicit rational polynomial is derived,based on which the corresponding laser marking algorithm is investigated.Then,a control system for the laser marking of NURBS images is developed on the DSP/BIOS-based real-time embedded platform.Experimental results show that high-performance embedded platforms satisfy the space and time requirements of the algorithm and help to implement the laser marking of complex NURBS images.
