Abstract：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 measurement 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.
