基于LabVIEW的相位式激光测距系统的软件设计与实现

摘要

针对传统应用CPLD, FPGA或ARM等嵌入式处理器的相位式激光测距系统,本文运用美国NI公司推出的“图形化”程序开发环境( LabVIEW),设计实现了基于LabVIEW的相位式激光测距系统的软件程序,用于对被测目标距离测量时的程序控制和数据处理。文章简述了相位式测距的基本原理及LabVIEW功能与实现,就相位式激光测距系统的程序控制和数据处理部分做了详细阐述,并给出了LabVIEW数据处理部分的相关测量仿真实验结果,为应用LabVIEW完成相位式激光测距的数据处理提供了一个可行的方案和参考。%phase laser ranging system based on the traditional application of CPLD, FPGA, ARM or other embedded processors, we design and implement the software of the phase laser distance measuring system, for controlling processes and processing data in the target distance or length measurement.The software was written in the “graphical” programming environment ( LabVIEW) which was launched by National Instrument company.This paper briefly introduces the basic prin-ciples of the phase distance measurement and implementation of LabVIEW function, the system control and data processing of the phase laser distance measuring system is introduced in detail, and the relevant measurement simulation and experi-mental results of the LabVIEW data processing part are given, providing a feasible scheme and reference dataprocessing phase laser ranging for LabVIEW application.
