基于模拟目标的激光测速仪校准新方法
One New Calibration Method of Laser Speedometer with Simulated Target
摘要
为解决激光测速仪测速范围和测速误差的校准问题, 满足激光测速仪的校准需要。根据激光测速仪的测速特点, 提出了一种基于模拟目标的激光测速仪校准新方法,并构建了校准装置, 该校准装置可以模拟匀速移动目标(代表匀速移动的车辆)提供标准速度值, 激光测速仪接收移动目标的反射光波后, 将给出该移动速度的测量值, 从而得到测速误差, 调整目标的速度, 即可实现对不同速度值的校准。经校准重复性试验和校准范围试验, 证明了该校准装置校准范围宽、重复性好、通用性好, 可以满足激光测速仪测速范围和测速误差的校准需求。
Abstract
This paper aims at range and error calibration of laser speedometer. According to the measurement principle of laser speedometer, one new calibration method and instrument with simulated target is put forward, which provides simulated target with invariable speed to simulate vehicle, and achieve range calibration by changing the speed of simulated target. Experiments show that the calibration instrument can meet the need of laser speedometer calibration because of its wide calibration range, high repeatability and universal performance.
