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視網膜病變原理和眼科屈光學的基礎上，進一步研究分析了新型免散瞳眼底照相系統和傳統眼底照相機原理和區別，擬採用3dsmax建立三維眼球模型，模擬眼球屈光系統，模擬眼底照相系統的小角度拍攝，使獲取的眼底圖像合理真實，解決後期系統圖像分析處理的對象來源問題;然後運用醫學圖像配準理論對模擬獲取到的九幅小角度眼底圖像進行快速拼接，拼成一幅大角度的眼底圖像，解決小瞳孔拍攝圖像視角太小的問題;最後通過對眼底圖像配準演算法在相似性測度和搜索演算法的比較，找到一種適合眼底照相系統的眼底圖像拼接的快速演算法。 -
