Method for positioning a container for measurement of wear in the container lining

Abstract

The invention relates to a method for positioning a container for measurement of wear in the container lining. The method comprises taking a reference picture by a camera means of a set of at least three reference marks mounted on the container, and performing reference measurement of the container lining with a measuring device emitting and receiving optical radiation. Later, in the actual measurement situation, a measurement picture is taken of the set of reference marks with the camera means, and the actual measurement of the wear in the container lining is performed with the measurement device emitting and receiving optical radiation. By comparing the measurement situation picture with the reference picture, correction factors are calculated, on the basis of which the actual measurement of the wear in the container lining and the previously made reference measurement of the container lining are combined so as to be represented in the same coordinate system.
