摘　　要：在进行非真实感渲染(NPR)处理时需要大量的计算,这对高帧率、高分辨率的视频做实时的NPR渲染是一个难题。根据FPGA以并行运算为主的特点,对传统的NPR算法做了改进和简化,最终设计了一种基于FPGA的实时NPR系统。实验结果表明,该系统对高帧率、高分辨率的视频做实时NPR处理具有运算速度快、系统稳定等特点,同时还具有体积小、便于携带等优点。During the NON-photorealistic rendering, a lot of computation is required. It is a challenge for high-frame-rate and high-resolution videos to do NPR rendering. This paper improves and simplifies the traditional NPR algorithm based on the parallel computing feature of FPGA, which finally leds to a real-time NPR system. The results of the experiments show that the system achieves real-time NPR video processing, capable of high frame rate, high-resolution video real-time NPR processing. And the system also have many advantages, such as volume is small, easy to carry.
