关于眼睛屈光学方面的研究 - The author mainly anticipates the task including the simulation of eye fundus imaging and image mosaic . on the base of the dr principle and ophthalmic phototropism study , the author analyze and contrast new fundus camera system with traditional fundus camera . the author will establish the eyeball model with 3ds max technology , imitate the simple eyeball dioptre system and simulate the narrow - angle imaging to ensure the rationality and authenticity of fundus image , which solves the object origin of later image process , then fast mosaics the nine piece of fundus images with the help of the image registration theory and acquire a piece of wide - view fundus image containing more information , thereby provides doctor with enough diagnostic detail , which solves the problem of narrow view
作者在熟悉糖尿病性视网膜病变原理和眼科屈光学的基础上,进一步研究分析了新型免散瞳眼底照相系统和传统眼底照相机原理和区别,拟采用3dsmax建立三维眼球模型,仿真眼球屈光系统,模拟眼底照相系统的小角度拍摄,使获取的眼底图像合理真实,解决后期系统图像分析处理的对象来源问题;然后运用医学图像配准理论对仿真获取到的九幅小角度眼底图像进行快速拼接,拼成一幅大角度的眼底图像,解决小瞳孔拍摄图像视角太小的问题;最后通过对眼底图像配准算法在相似性测度和搜索算法的比较,找到一种适合眼底照相系统的眼底图像拼接的快速算法。
