To address the issue of insufficient measurement accuracy for pose deviations of forked lugs in aircraft wing-body docking assembly, this paper proposes a binocular vision-based method for detecting assembly deviations of aircraft wing-body forked lugs. First, an assembly deviation detection system for aircraft wing-body forked lugs was established. Then, a binocular vision-based detection model for forked lug assembly deviations was constructed. The RANSAC algorithm was employed to fit the edges of the lug holes and eliminate outliers. Triangulation was used in conjunction with a laser tracker and reference plate to transform the hole center coordinates in the camera coordinate system to the global coordinate system. Additionally, the triangulation method was applied to calculate the 3D coordinates of points on the mating surfaces of the lugs and fit the boundary lines. Finally, assembly deviations were computed according to the mathematical models of coaxiality and clearance deviation. Experimental results demonstrate that compared with traditional monocular vision detection, this method effectively reduces the detection deviations of lug coaxiality and clearance. %K 机翼, %K 机身, %K 装配, %K 双目视觉, %K 偏差检测
