摘要
在景象匹配系统中 ,实时图由于受到噪声和畸变等因素的影响 ,经常无法有效、准确地找到其实时匹配位置。建立了实时图的受干扰模型 ,得出了信噪比和相关值之间的定量关系式 ;然后通过分析实时图的畸变模型 ,得出了可匹配条件下 ,实时图畸变方差的上限值。这些研究工作 ,对于分析受干扰实时图对景象匹配的影响 ,具有重要意义。
In image-matching system, there is a problem that it is difficult to find the real-time matching position efficiently and precisely because of noise and distortion, etc. This paper sets up the model of interfered real-time image, and reaches a conclusion of the quantitative relation between SNR and correlation. This paper also analyzes the model of a distorted real-time image and obtains the upper limit value of the distorted variance of the real-time image under the condition of matching.
