[0002] In the field of aircraft component assembly, automatic hole drilling equipment has been applied more and more widely, and the research on automatic hole drilling equipment has also become one of the current research hotspots. The current automatic hole drilling equipment mostly adopts the reference hole compensation method, and its main process is to first manually open two holes as reference holes on the wallboard, skin and other parts, the automatic hole drilling equipment uses the visual system to take the reference holes as the theoretical position of the parts and fits the calculation, and uses its own precision compensation algorithm to drill holes after compensation between the two reference holes.

[0003] However, due to the influence of the reference scanning precision, the self-moving precision and the compensation algorithm of the automatic hole drilling equipment, and the need for maintenance after long-time use of the equipment, this hole drilling method may cause certain deviation of the hole position. In order to check this error, there are currently two checking methods: line drawing method and line pulling method. The line drawing method draws a straight line between the two reference holes, and the operator measures the distance of each point from the center line with a vernier caliper. This method measures by the naked eye, and the data obtained is not accurate enough. The line pulling method pulls two lines above and below as the out-of-tolerance lines between the two reference holes, and any point that exceeds the out-of-tolerance line range is considered as an unqualified point. This method also relies on the naked eye observation, and cannot obtain accurate distance data between the hole positions, which is not conducive to the hole position checking and calibration of the product.
