摘要
激光三角测距器作为一种非接触、高精度的检测仪器,其工作环境、安装方式、测量条件等因素对测量精度的影响限制了其在石油管螺纹测量领域的应用。针对这一问题,本文结合实际螺纹测量情况,通过大量实验探究滤波方式、测距器移动速度、方向、反射镜面积等因素对测量数据廓型的影响,分析产生误差的机理,并确定出合理的测量方案,为螺纹在机测量系统的设计提供了理论和实验依据。
The laser triangulation range finder, as a non-contact and high precision detecting instrument, its working environment, installation methods, measurement conditions and other factors influence its measurement accuracy, which limits its application in the field of petroleum pipe thread measurement. In order to solve the problem, this paper, combined with the actual measurement of the thread, explore the influence of the filter mode, the moving speed, the direction, the area of the mirror and the other factors on the profile of measure- ment data through a large number of experiments. The mechanism of the error is analyzed, and the reasonable measurement scheme is determined, which provides a theoretical and experimental basis for the design of thread measurement system.
