基于超声波原理的直升机驾驶员头部位置检测方法研究

摘要

超声波测距是一项价格实惠的非接触性技术，利用超声波测距原理实现驾驶舱中驾驶员头部位置的检测。首先介绍了测量系统的工作流程，然后阐述了测量装置的组成并提供了三维坐标的计算方法，最后建立了测量装置的检测精度及测量范围的测试平台。%Uitrasonic ranging is an affordable non-contact technology.The paper demonstrates how to detect the pilot head po-sition in the cockpit by applying the ultrasonic distance measurement principle.In this paper, the working process of the meas-uring system is introduced, and then the composition of measuring devices and the 3D coordinate calculation method are ex-pounded.Besides, the detection precision of the measurement device and the test platform of measurement range are also fig-ured out.
