摘要

针对飞机蒙皮对缝阶差与间隙的数字化检测问题，以线结构光视觉测量技术为基础，提出了阶差与间隙测量模型，从阶差与间隙的尺寸和位置两个方面设计测量方法。使用线结构光视觉传感器完成阶差与间隙的尺寸测量，同时利用iGPS 测量系统对视觉传感器的位姿进行实时跟踪测量，从而确定阶差与间隙的测量位置。通过试验验证了算法的正确性和稳定性，能够实现非接触、高精度测量：试验结果表明：5mm 内阶差的重复测量精度优于0.04mm，间隙的重复测量精度优于0.05mm。

Abstract

Aiming at Dealing with the stepped difference and gap of aircraft assembling

this paper comes up with an algorithm of the stepped difference and gap based on the structural light measuring theory from the size and position of them. This paper completes the measurement of the stepped difference and gap of the aircraft skins with the linear structural light vision sensor

and the pinpoint position of the measurement can be confirmed by using the indoor-GPS. As is confirmed by experiments

the result of the algorithm is quite stable: the repeat precision of the stepped difference within 5mm is not more than 0.04mm and the repeat precision of the gap is not more than 0.05mm.
