Abstract

In a crankshaft testing method for the classification testing of at least one bearing surface of a crankshaft or the like, a reflection of a reference object at the bearing surface to be tested (reflection image) is detected by at least one sensor, using a sensor system. The detected reflection image is evaluated with regard to its contrast, and the crankshaft is classified as “unsatisfactory” when the contrast is below a predefined or predefinable threshold value.
