Abstract
A method and a device for measuring wear on the internal surfaces ( ) of barrels ( ), in particular weapon barrels. For a very precise determination of the wear on the internal surfaces ( ) of barrels ( ), a non-contacting scanning of the internal surface ( ) of the respective barrel ( ) to be checked is carried out with a light-spot triangulation sensor ( ), to determine the respective distance between the internal surface ( ) and the barrel axis ( ) for selected sensor positions. The contour of the internal surface ( ) of the respective barrel ( ) is then determined from the detected distance changes. It has proven advantageous if the measured distance values are displayed on a monitor ( ) in the form of a C-image, wherein different distance ranges are characterized with different colors, so that faulty surface areas can immediately be recognized optically.
