Internal thread testing system, internal thread testing method and computer program

摘要

The invention relates to a Innengewindeprüfsystem for performing an automatic optical inspection of an internal thread, comprising at least one camera with a lens and a first light source, wherein the first light source for emitting light is directed toward a light entrance side of the lens, wherein the Innengewindeprüfsystem for testing the internal thread by arranging the component with the internal thread to be tested in the light beam path from the first light source to the objective and by evaluating the counter light of the first light source passing through the internal thread and received by the objective. The invention further relates to a method for internal thread testing by means of such internal thread testing system and a computer program.
