Claim 0:
1. A method for measuring a thread, comprising:
moving a contactless distance sensor parallel to an axial direction of the thread;
recording a measurement signal corresponding to a distance of the contactless distance sensor to a top of the thread;
comparing the measurement signal with a reference value lying between a maximum value and a minimum value of the measurement signal;
determining intersection points of the measurement signal with the reference value;
combining a first two intersection points, directly following one another, into a first measurement value tuple;
combining a second two intersection points, directly following one another and directly following the first two intersection points, into a second measurement value tuple;
calculating a first mean value of the first measurement value tuple;
calculating a second mean value of the second measurement value tuple; and
calculating a time-angle resolution from the first mean value and the second mean value.
