摘要

This paper presents a method for blast furnace lining thickness measurement with a 3D laser scanner and image registration method. A laser scanner is used to measure the inner profile through an opening on the upper part of the furnace. Two data point sets are obtained before and after the lining repairing process respectively, and data registration algorithm is employed to acquire rigid body transformation so as to compare the difference between both point clouds based on the same coordinate system. The difference represents thickness added to the initial lining. Furthermore, by comparing mechanical dimensions with the measured profile, residual lining thickness can be obtained.
