The invention provides a ship construction inspection method, which comprises the following steps of: firstly, selecting a design model of a ship construction part, selecting path points according to internal space characteristics of the design model, and planning a shortest path penetrating through all the path points; and carrying out patrolling shooting on the ship building part according to the shortest path to obtain image data of the ship building part. And further performing three-dimensional model reconstruction according to the image data to obtain a reconstructed model of the ship building part. And then, removing accessories except the ship structure from the reconstruction model to obtain a pure reconstruction model of the building part. And then selecting a proper angle according to the path points, and respectively intercepting pictures in the pure reconstruction model and the design model at the same path point and the same angle so as to obtain a reconstruction picture and a design picture at the same position. And finally, comparing and checking the reconstructed picture and the design picture to obtain and output a checking report. According to the ship construction inspection method, the problems of wrong loading, neglected loading and sundries remaining in the ship construction process can be identified.
本发明提供一种船舶建造检验方法,首先选取船舶建造部的设计模型,根据设计模型的内部空间特征选取路径点,规划出贯穿所有路径点的最短路径。接下来按照最短路径对船舶建造部进行巡飞拍摄,以获得船舶建造部的图像数据。进一步根据图像数据进行三维模型重构以获得船舶建造部的重构模型。然后自重构模型中剔除船舶本身结构之外的附件,以获得建造部的纯净重构模型。随后按照路径点选取适当角度,在同一路径点和相同角度下分别在纯净重构模型和设计模型中截取图片,以获得相同位置处的重构图片和设计图片。最后对重构图片和设计图片对比检验,以获取并输出检验报告。本申请的船舶建造检验方法能识别出船舶建造过程中错装漏装和遗留杂物的问题。
