Research on the automatic measurement algorithm of spherical valves

In order to solve the inefficient production of spherical valves which are manufactured by manual template scribing, semi-automatic cutting on the track and manual test, this paper designs an automatic measurement algorithm which uses laser displacement sensor to measure sphere valves. First according to the divided flap of spherical tank and the outline requirements of spherical tank, establish the ideal model of the measurement trajectory. Then transform the ideal model of sphere valves to the practical situation. At last, use the actual measurement trajectory data to guide the machine to measure the sphere valves and process the measurement data by median filtering and moving average filtering. The practice shows that the algorithm is feasible and effective and has important practical significance to improve the efficiency and shorten the construction time.
