In order to improve the requirements of new aircraft assembly testing, an assembly detection method based on Lidar was proposed. Lidar was used to measure the positioning datum of assembly parts. The measurement data was analyzed and the key dimension information was extracted to solve the assembly problem fundamentally. Combining with an assembly test example of a certain part of the aircraft, the assembly problem is detected and analyzed, which solves the problem of over-size matching in the aircraft assembly process. The results prove that the assembly detection technology based on lidar can detect the assembly problem of aircraft efficiently and accurately, which is of great significance to realize the digital automatic assembly of the aircraft.
