基于裸眼3D技术的眼科多媒体库的设计与开发

Design and Development of Ophthalmic Multimedia Library Based on Naked Eye 3D Technology

摘要: 《眼科学》是研究人类视觉器官疾病的发生、发展及其防治的专门学科，是医学院校本科学生的必修课程之一。传统眼科学相关知识教学方法主要以课堂讲授、静态图片、2D视频为基础，难以全面学习眼球立体解剖和疾病层次特征，存在教学与临床实践脱节的情况。近年来3D技术快速发展，但存在穿戴设备束缚、长时间使用眩晕感、多倍变焦导致分辨率降低、中心视野成像而周边视野剥夺、价格昂贵等较多的限制条件而难以推广使用。本文通过眼科图库收集、3D主要技术应用、3D显示技术与识别技术、教学与评价四个部分建立裸眼3D眼科APP多媒体库，使眼球这一结构复杂的视觉器官展示出三维空间纵深感，清晰化显示眼科疾病的特征，基于外贴3D光学膜适配市面上主流的手机机型与平板电脑，让老师和学生可以在不更换现有设备的情况下开展裸眼3D《眼科学》教学，能够为学生提供更为直观的教学过程。

Abstract: Ophthalmology is a specialized subject that studies the occurrence, development, prevention and treatment of human visual organ diseases. It is one of the required courses for undergraduate students in medical colleges. The teaching methods of traditional ophthalmology related knowledge are mainly based on classroom teaching, static pictures and 2D videos, which are difficult for students to learn the stereoscopic anatomies of the eye and the hierarchical characteristics of the diseases comprehensively. Meanwhile, teaching and clinical practice are separated. In recent years, 3D technology has developed rapidly, but it is difficult to promote due to many restrictions, such as the shackles of wearable devices, the dizziness of long-time use, the reduction of resolution ratio caused by multiple zoom, the central visual field imaging and the peripheral visual field deprivation, and the high price. In this paper, the naked eye 3D ophthalmic app multimedia library is established through four parts: ophthalmic image collection, 3D main technology application, 3D display technology and recognition technology, teaching and evaluation, to help the eyeball, a visual organ with complex structures, shows the three-dimensional spatial depth and the characteristics of ophthalmic diseases. Based on the application of 3D optical film adapted to the mainstream mobile phone models and tablet computers in the market, teachers and students can carry out naked eye 3D ophthalmology teaching without replacing existing equipment, and can also provide a more intuitive teaching process for students.
