摘要

提出了一种基于自适应算法的移动激光测距仪实时标定模糊方法。这种测量系统的主要误差来源是环境温度变化引起的漂移误差。它可以使用基于激光脉冲通过光纤恒定段传播的飞行时间测量的重复进行校准来补偿。为了使标定率最小化，我们设计了模糊标定器，跟踪漂移误差的实际变化并计算出最佳标定率。该方法已在移动激光测距仪上进行了测试，单次射击精度为3cm

Fuzzy calibration for pulsed time-of-flight laser rangefinder

A fuzzy approach to real-time calibration of mobile laser rangefinder is presented as an alternative to the methods based on adaptive algorithms. The main error source in such a measurement system is drift error due to the changes of ambient temperature. It may be compensated using repeatedly performed calibration based on the time-of-flight measurement of laser pulse propagating through the constant section of optical fiber. To minimize calibration rate we designed fuzzy calibrator that traces actual changes of drift error and calculates the optimum rate of calibration. This method has been tested using mobile laser rangefinder with 3 cm single-shot accuracy
