An Improved Method for Evaluating Measurement Repeatability Based on Pauta Criterion
In order to solve the problem that the repeatability of vertical measurement system is easily interfered by environmental noise.This paper proposes an improved repeatability evaluation method based on Pauta Criterion.The method divides the high-frequency measured data into multiple sam-ples,processes the data for each subsample and then performs Pauta Criterion calculation.By com-paring the evaluation indicators before and after the improvement and conducting spectral analysis,the results show that the evaluation method can more accurately represent the performance of the ver-tical measurement system and the influence of environmental noise on repeatability.
