Abstract
A first thread feature is measured by detecting with an optical sensorlight that reaches from a light sourcelocated on the opposite side of a pipe axis and runs substantially in parallel to thread grooves A. A contact probeof a contact sensoris contacted with a thread flank surface Ato detect the space coordinates of the contact probeat the time of contact, so that a second thread feature is measured. The first and second thread features thus detected are combined with each other by a processor, and thread features of the thread provided as a measurement object are thereby calculated.
