Research on Geometric Dimensioning Automatic Detection of Tubular Member

Abstract:

Geometric dimensioning measurement is a very important application in metrology. In this paper, we focus on the geometric dimensioning automatic detection of tubular member based on the laser displacement sensor. An automatic detection system of tubular member is designed using line laser scanning principle. The system includes base, swivel table, servo motor, motor driver, servo pack, motor controller, laser displacement sensor, data acquisition card, and computer. The system first gathers the displacement information by laser displacement sensor, then performs coordinate transformation and three dimension reconstruction of the tubular member. The external diameter and the roundness error can also be measured. The experimental results show that the geometric dimensioning parameters measurement is effective and accurate using this method.
