Abstract The manufacturing accuracy of aviation tube is one of the important factors that affect the assembly quality, it is necessary to inspect the manufacturing accuracy of tube before assembly. At present, the commonly used inspection method is to verify by mechanical checking-tools, but there are some defects such as low precision and low efficiency. So an efficient and accurate digital inspection technology of tube is proposed, in order to ensure the accuracy of inspection results and improve the production efficiency of tube. Non-contact measurement method is used to obtain the surface point cloud data of tube based on laser scanning technology, in the inspection system, the central axis, bending points and bending elements of point cloud data are extracted to make error analysis compared with the theoretical model of tube, and then the bending coefficient can be corrected, and high quality tubes will be produced by sending the correction data to the bending machine.
