Abstract

Abstract

This study analyzes factors affecting the measurement accuracy of laser meters, identifying three key factors: the movement speed, the angle of incidence between the measurement line and the measurement surface's normal, and the spacing distance between the laser transmitter and the measurement surface. Employing a controlled variable method, one factor is varied while the others remain constant, and the impact of each factor on measurement accuracy is determined by comparing and analyzing the laser meter's distance measurement indication error. Experimental analysis reveals that the angle of incidence between the measurement line and the normal of the measurement surface is the primary influential factor, followed by the distance between the laser transmitter and the measurement surface, both requiring strict control to maintain error within the instrument's nominal accuracy. The effect of movement speed and state on accuracy is minimal, thus not a primary factor. Consequently, special attention should be given to the placement angle and distance from the measurement surface when using and calibrating the laser meter to achieve high measurement accuracy.
