中文摘要： 响尾蛇能够同时感知可见光与红外输入信号，并且能够通过神经系统的处理实现对可见光图像和红外图像的融合,从而得到所感知目标的重要特征，这与人眼的视觉特性有很大区别。本项目以响尾蛇的颊窝红外图像感知以及视顶盖的可见光图像和红外图像融合机制为主要研究目标，对其生物学机制以及相关的神经元活动进行研究，侧重于工程可计算数学模型的建立。主要研究内容有:研究与响尾蛇颊窝红外成像机制相关并且可用于数学建模的各种生物学研究成果和物理模型，结合针孔成像模型解释颊窝红外成像机制,将针孔成像相关理论应用于颊窝成像以及还原。针对红外图像增强，图像还原等问题设计相应的仿生学图像处理算法。研究视顶盖的可见光图像和红外图像融合机制，全面利用视顶盖神经元相互作用的几种模式进行数学建模，结合颊窝红外图像的感知模型建立一种更加完善的描述响尾蛇视觉系统的数学模型，最终进一步优化该模型并且针对图像融合问题设计相应的仿生学算

英文摘要： Rattlesnakes can sense the infrared stimuli and visual stimuli simultaneously. Also they can possess a neural system to perceive a two dimensional image by merging the infrared signal and visual signal in order to obtain the details of the target in their surrounding. These properties are very different from the human visual system. Aiming at explaining the infrared image sensing of pit organs and merging mechanism in the optic tectum, biological mechanism and the relative neural behaviors are deeply analyzed. Arithmetic methods will be taken into consideration in order to establish a biologically inspired model with practical value. Its main contents are as follows: the physical models and biological methods which are relative to the infrared imaging of pit organs are studied in order to establish arithmetic models. The pinhole imaging model is used to explain the pit organs imaging mechanism. On the basis of that, to design methods for image enhancing and image restoration, the plan for biologically inspired approaches are introduced. The pinhole imaging relative theories will be used in this process. Utilizing the interactional modes among neurons in the optic tectum makes for the establishing of arithmetic models based merging mechanism in the optic tectum. To obtain a more comprehensive model to describe th
