Assembly Correctness Identification of Internal Part of Complex Component Based On X-Ray

An element perception and state recognition method oriented to complex assembled product

“…For applications with a fixed view, the target is usually treated as a flat structure, and a bird's-eye view angle that can reflect the overall product is selected for imaging. Many related studies such as piston missing installation detection [9], aircraft semi-enclosed space cabin status detection [10], fastener missing prevention [11], electronic component detection [12,13], plate-type parts defect detection [14], railway component inplace detection [15], and CT technology-based internal component assembly unit inspection [16] involve this approach, taking the normal image from the top view as a reference while adopting interested patches or simple low-dimensional features. In terms of element recognition, when there are fewer categories of objects to process, a trained model (e.g.…”

“…Output W with the minimum f . End segment is selected by (16), where Hm i is replaced by H m . ¢ the line segment satisfying (16) in ¢ L is kept as a candidate, and the line segment without correspondence is eliminated from ¢ M with a probability of 50%.…”
