摘　　要：针对现有的物理光学系统建模方法普遍存在运算量较大、执行速度较慢的现状,提出了自适应多尺度光学边缘检测建模的思想.利用小波分析的去噪重构原理,通过对光学边缘检测的结果建立不同等级的阈值,由多等级的阈值的确立实现对被测物理对象光学模型边缘的多尺度锐化,实现对光学模型的去噪,进而实现所建立的物理光学系统的模型能够在面对不同的边缘尺度下保持一定的自适应,对于进一步提高光学建模的方法及研究具有一定借鉴意义.Aiming at the fact that most of current modeling methods of physical optics all have the problems of large calculation and slow operation speed,this paper pointed put the adaptive multi-scale modeling of optical edge detection method,which took use of wavelet’s principle of reconstruction and de-noising,and the different levels of threshold was built by making use of results belonged to optical edge detection,and the physical optics model could be sharped from multi-scale by a number of the established threshold levels,so that the physical optics model could maintain a certain self-adaptive and de-noising when it faces with the different edge scale.All this work is significative for enhancing the research level of physical optics modeling methods.
