摘要
传统方法在实时仿真环栅激光图像时对边缘拟合不完整,清晰度差、图像识别率低、亮度分布不均匀、环栅激光图像受到外部环境的干扰较强。提出一种基于实时重光照模型的环栅激光图仿真方法研究,搭建适用于仿真环栅激光图的实时重光照模型,基于模型多次拟合环栅激光图像的各层环形边缘曲线、绘制圆心,提高光照分量的识别能力并对其进行归一化处理,最后合成重光照图像,完成对环栅激光图像的仿真。试验证明文章的方法能够有效地实现对环栅激光图像的实时仿真研究。
In the traditional ring laser real time simulation, the edge fitting is incomplete, image definition is bad, the recognition rate is low, the brightness distribution is uneven and the interference from outside is strong. So, a ring laser simulation based on real time relighting model is put forward. Building the real time relighting model which is used for simulating ring laser. Multiplex fitting the edge curve in each layer of the ring laser image based on this mod- el, and drawing the center of circle. Improving the recognition of lighting weight and normalizing. Finally, synthesi- zing relighting image and complete the simulation. The proposed method can realize the real time simulation of ring la- ser image effectively.
