SYSTEM FOR MEASURING WAVINESS OF AIRCRAFT SURFACE AND CORRESPONDING METHOD

摘要

A system for measuring the waviness of an aircraft surface and a corresponding method. The system comprises the following components: a laser contour scanning module for emitting laser to an aircraft surface, for receiving laser reflected back from the aircraft surface, and for obtaining the data representing the cross-sectional contour of the aircraft surface; a digital signal processor for processing the data from the laser contour scanning module and obtaining data that can be processed by a waviness calculation module; said waviness calculation module for calculating the waviness of the aircraft surface according to the processed data representing the cross-sectional contour of the aircraft surface. The system can instantaneously obtain the waviness information of a cross section of the aircraft body surface being measured with no contact required. The information collection process is quick and efficient, and can effectively avoid errors generated during the data collection process.
