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.

Key words： laser marking; non-uniform rational B-spline; DSP/BIOS
