In a light-slit method, a first and a second measurement light projection on a surface of an object to be measured may be unambiguously identified as a first or a second measurement light projection by a camera when there is a support apparatus operating the camera and/or the measurement light projectors such that, in each light-slit recording of the camera, either the first or the second measurement light projection is visible to the camera. The possibility of unambiguous identification allows evaluating several spatially overlapping and not exactly aligned measurement light projections by means of a camera.

Apparatus and method for measuring the surface of a body

In a method for characterizing a surface comprising a localized unevenness, a contour line of the surface is initially created as a function of a location variable. Subsequently, the localized unevenness is detected in the contour line and eliminated from the contour line, so that an incomplete contour line results as a function of the location variable, which characterizes the surface without the localized unevenness. The incomplete contour line may be used to either be able to evaluate the surface without any localized points of unevenness, for example to determine the side wobble or height wobble of a tire, if the surface is a side flank and/or a running tread of a vehicle tire, or to classify the localized points of unevenness without any influence of the surface.
