【 摘 要 】

Generally, cell guides are installed in the cargo hold of container ships, which improvethe loading and unloading efficiency of containers and fix containers when the ship is sailing.However, in actual production, due to the low accuracy of ship loading in sections, and thedeviation of welding shrinkage and expansion in relevant sections, errors occur in the loadingprocess of containers, resulting in hidden safety risks or significant economic losses. Giventhe above situation, it is particularly important to find a high-efficiency cell guide accuracyinspection method for construction monitoring. 3D scanner to obtain three-dimensional data ispresented in this paper, based on this paper proposes a new method, this method will be usedbased on improved instances of 3 d point cloud segmentation model to cell guide thesegmentation, and fitting container ship cell guide structure, and then realize the function ofcontainer simulation test box, cell guide after the segmentation precision inspection at thesame time, for the practicality review, we compared the accuracy data gained from inspectionsimulation and the measured data. As a result, it was confirmed that both values were withinabout ±1.5mm. The validity, and reliability of the method are further verified.
