摘要

指出了超声波在测距应用中的局限性

并给出解决方案。着重从新的角度补偿超声传感器的误差

提出了用BP前馈神经网络补偿超声波声速受温度、湿度变化而引起的误差。在室外工作的测距仪上

应用该补偿方法后超声测距的精度提高了2个数量级。本方案适用于高精度要求或复杂环境下超声测距。

Abstract

The limitation of the ultrasonic sensor in distance measuring is analyzed

and the scheme solved is put forward.The ultrasonic velocity sound error caused by change of temperature and humidity is compensated by BP neural network.Applied this method to ultrasonic distance measuring in the outdoor

the precision is up two grades.The proposal is suitable for ultrasonic sensor at complex environment or high precision.
