摘要
介绍了一种计算机辅助智能视力检测仪。被检者通过操作手持遥控器来判别视标的开口方向,系统自动检测并判别其正误,最后打印出检测报告。系统测定的视力范围从对数视力3 .0 到5 .3 ,同时系统带有红外超声自动测距功能,以保证测量结果的准确性。
The paper introduces an intelligent vision testing instrument,which works on automatic method or manual method.The examinee inputs his or her judgement about the direction of the letter “E”with remote control.The system examines and judges the examinee's judgement,and then prints the testing report.The vision testing range is from logarithm vision 3.0 to 5.3. The distance between examinee and optometer can be measured automatically by the system with infrared and ultrasonic testing functions and a good accuracy
