眼底照相机 meaning in Chinese
fundus camera
Examples
- Fundus camera is currently one of the effective and popular dr screening instruments and it will gradually replace the traditional ophthalmoscope instrument
眼底照相机就是这样一种被广泛采用的、有效的糖尿病性视网膜病变筛查工具,并逐渐取代了传统的检眼镜等眼科检查设备。 - Due to the rapid progress of computer technology and development of image analysis technique , the fundus images could be processed , enhanced and analyzed both quantitatively and objectively
此系统更可以配合非散瞳式眼底照相机，作为定期大量健康筛检或长期追踪病程的工具。 - Therefore , the project research on remote dr screening and image analysis system , which is the joint project of ministry of sanitation and ministry of education in fujian province , designs a new kind non - mydriatic camera system which overcomes the above problems by the particular optic design and the exact control software
为此福建省卫生教育联合攻关计划项目? ? “远程糖尿病性视网膜病变筛查及图像分析系统的研究” ,提出了一种新型免散瞳眼底照相系统,通过独特的光学设计和精密的控制软件,基本克服了传统眼底照相机存在的缺点。 - Using the way combining the mathematic morphology top - hat and gauss matched filtering can effectively reduce the influence of the inherent fovea and the marginal noise brought forth by the retinal camera caliber in retinal image and increase the precision of retinal image segmentation and feature point extraction
文中提出了采用灰度数学形态学中的top - hat变换和高斯匹配滤波相结合的方法，用来有效的降低视网膜荧光图像中固有的小窝现象及眼底照相机的口径所引起的视网膜图像边界像素噪声，极大的提高了图像分割及特征提取的精度。 - 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。
