Research progress on detection technology of large-size aircraft parts

Large-size aircraft parts have complex structure and huge external dimension characteristics. In view of the research of large-size measurement technology in the aircraft manufacturing process, five kinds of detection technology methods for large-size parts, like three-coordinate measurement method, LIDAR measurement method, indoor GPS measurement method, laser tracker measurement method and machine vision measurement method were proposed. The applicable fields and respective advantages and short-comings of five detection methods were analyzed. The visual measurement which can achieve real-time measurement has non-contact, high precision and efficiency characteristics. It has a great prospect in the field of aviation measurement. It was pointed out that vision measurement technology is research direction in large-size measurement. A series of issues such as the theoretical models establishment, detection parameters optimization and real-time feedback need to be further studied in the future.
