Abstract The quality and performance of the airspace thread directly affects the safety of the aircraft, so the precise
measurement of the thread parameters is very important. The optimal measurement method using the thread integrated
scanner is determined by comparing the advantages and disadvantages of several traditional measurement methods. This
method has the advantages of reliable accuracy, complete parameters and high efficiency. In addition, the measuring principle
of the method using thread integrated scanner is introduced, and error analysis is carried out. Finally, the reliability
of the method is verified by comparing the results of several different measuring methods on the same thread and doing repeatability
and stability test.
