摘要
研究了一种基于嵌入式系统和超声波测距系统的设计方案。应用移植嵌入式操作系统并给出障碍物检测优化方法，并且根据超声波测距的工作原对障碍物进行距离测量。实验结果表明，该系统在自然盲道情况下达到了处理实时性和判断的准确性要求，可较好地服务于盲人的独立出行。
Studies are made on the embedded systems and ultrasonic distance measurement system.Porting embedded operating system and giveing optimization method for obstacle detection,and measuring the obstacles distance by ultrasonic ranging works.The experimental results show that the system achieved to deal with circumstances and judge the accuracy of real-time requirements in a natural blind road,which may provide better serves for the blind＇s independent travel.
