摘要光纤制导作为一种新型的高带宽的图像制导方式,正逐渐受到越来越多的关注,并应用于众多系统中。光纤从光纤线包上顺利释放,是进行光纤制导研究的重要部分。为保证光纤释放的成功率,必须建立光纤释放的动力学模型,寻找最佳的光纤释放结构。而建立可靠模型的前提是精确测量光纤在光纤线包上的密排状态和光纤脱离光纤线包表面时的飞行轨迹。67772
本文首先针对光纤线包上的光纤密排状态的识别问题,基于光纤线包上光纤密排图像的特性,通过Radon变换理论进行分析。采用MATLAB软件编写了Radon变换的实现程序,对光纤线包不同区域的光纤排列结构进行了倾角识别。其次,研究并实现了曲线跟踪算法,通过此算法实现对光纤脱离线包表面时的轨迹的自动识别。
通过本文的研究,基本的实现了对高速摄像机拍摄的光纤释放图像中的光纤识别,取得较好的效果,为光纤放线中的光纤识别问题提供一种有效的图像识别方法。

Title The research of fiber releasing image recognition technology based on Radon transform
Abstract
Optical fiber guidance which is a new kind of image guidance with a high bandwidth is being paid more and more attention and being used in many systems. The successful releasing of the fiber from the solenoid is the key technology of optical fiber guidance. To ensure the success rate of fiber releasing we have to build the dynamical model to find the best structure of fiber releasing .while the accurate measurement of the array of the fiber is the premise of the model building.
In this paper we used the Radon transform theory to analyze the feature of fiber arraying on the solenoid. And programmed the Radon transform on matlab, Based on the result of the Radon transform we reappeared the array mode of the optical fiber on the solenoid. In the last we introduced a simple curve tracing algorithm and programmed the algorithm on matlab.
Through the study of this paper, we successfully did the recognition of the array of the fiber, and got a good result .provided a new way of the recognition of the releasing of the fiber.
Key words: Image processing、Radon transform、curve tracing
