Abstract
The invention relates to a method for measuring wear in the lining of a container provided with a pivoted axle and an opening, and a container. Fixing of the coordinate systems (16, 17) of a measuring device (1) and the container (6) is performed by measuring the position of fixing points (P1, P2, P3) in the coordinate system (16) of the measuring device, whereafter the i0 lining (10) on the inner surface of the container (6) is measured. The fixing is performed by measuring the position of the fixing points (P1, P2, P3) mounted in connection with the container in the coordinate system (16) of the measuring device (1) in a situation where the opening of the container faces away from the measuring device while the measuring device is directed towards the container bottom. The container (6) is rotated around its pivoted axle (11) to a position in which the opening (9) of the container (6) faces the measuring device (1). The fixing is performed utilizing the angle difference between angle data (.alpha..sub.1) obtained during the measurement of the fixing points (P1, P2, P3) and angle data (.alpha..sub.2) obtained after the rotation of the container (6), said angle difference being obtained by angle measurement known per se, measuring the inclination of the container (6).
