A Method of Improving the Laser Measurement Precision for the Electro-Optical Observation and Aiming Device Used in Fire Control
摘要
针对消防用光电观瞄系统对激光测距的高精度要求,提出了一种提高激光测距精度的方法.该方法采用基于FPGA的延迟线内插技术来减小计数量化误差,并且以差分GPS标定数据为基准,运用分段线性拟合的方法对实测数据进行修正,通过与差分GPS标定数据比对试验验证表明,该激光测距系统精度可以达到0.8 m,满足消防用光电观瞄系统≤1 m的测距精度要求.
Abstract
According to the high laser measurement precision requirements of the electro-optical observation and aiming device used in fire fighting,a method to improve the laser measurement precision is presented.A delay line interpolation technology is used to decrease the count quantization error,and the measurement data is modified by the method of piecewise-linear fitting,based on differential GPS data.The test results show that the laser measurement precision can reach 0.8 m.It meets the requirement of measurement precision.
