手持式激光测距仪检定方法及系统研究

针对现有手持式激光测距仪检定方法所需场地大、室外环境干扰因素多的问题,提出了一种“小空间长距离”的测量方案,基于此方案研制的手持式激光测距仪检定装置,以高精度全站仪的示值作为长度基准,利用镜面反射原理,在室内16 m长导轨上复现50 m标准长度,消除了野外测量中环境因素的影响。实验结果表明,检定系统满足JJG 966-2010《手持式激光测距仪》检定规程中示值误差检定技术要求,可以实现对手持式激光测距仪示值误差的检定。

Research on the Verification Method and System of Hand-held Laser Rangefinder

The existing verification methods of the hand-held laser rangefinder have the problems of large space requirement and many interference factors of outdoor environment. A measurement method of “small space for long distance” is presented and the verification device of hand-held laser rangefinder is developed. The indicating value of a total station is used as length basis. The 50m length is produced indoor on the 16m guide rail by the mirror reflection principle. The environmental influences in outdoor measurement are eliminated. The experimental results show that the verification system can meet the indication error requirements in the verification regulation of “JJG 966-2010” about the hand-held laser rangefinder. The indication error verification of the hand-held laser rangefinder is realized.
