基于BMI的融合功能检查系统的分析与设计

Analysis and design of binocular fusion examination system based on BMI

针对"传统的弱视双眼融合的视觉功能检查方法效率低,且通常依赖于医生的临床经验与专业医疗知识,检查的结果是定性的,不便于临床准确诊断"的问题。根据心理物理学的最新研究成果,设计了一种基于BMI(binocular motion integration)理论的融合视觉功能检查系统。采用VC++与Matlab混合编程技术实现了系统开发;使用CRT显示器和视频转换卡,解决了刺激源灰度模式下的显示问题。经临床试用表明,系统操作方便,能够帮助准确诊断,对早期有效恢复双眼融合视觉功能具有重要的意义。

In order to improve the accuracy and efficiency of amblyopia binocular fusion diagnoses,according to the latest results of psychophysical research,a new examination system of amblyopia binocular fusion based on the binocular motion integration（BMI） theory was designed.The software was realized by using VC＋＋,Matlab hybrid programming technique.Meanwhile,the video switcher card and CRT monitor were implemented to solve the problem of grayscale display accuracy.The test results indicate that the system is convenient for usage and has higher diagnostic accuracy,which is significant for restoring the visual function of binocular fusion in the early phase.
