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.
