针对传统船舶型线测量方法存在工作强度大、效率低等缺点,依托近年来迅速发展的三维激光扫描技术以及逆向工程领域的切片技术,提出了一种基于点云切片技术的船舶型线生成方法。该方法将船舶点云数据沿着指定的方向进行切片,再将切片点云投影到平面栅格,然后将落入到每个栅格内的点云重心化并将其作为特征点,从而快速构建点云特征轮廓线,最后得到船舶型线图。经实例验证,该方法可以快速、准确地生成船舶型线,为船舶型线的测量提供了一种全新的技术手段。
Aiming at the shortcomings of traditional ship profile measurement methods, such as high working intensity and low efficiency, based on the rapid development of 3D laser scanning technology in recent years and the slice technology in reverse engineering, a ship line generation method based on point cloud slicing technology is proposed . This method slices the ship’s point cloud data in a specified direction, projects the slice point cloud onto a plane grid, and then centers the point cloud falling within each grid as a feature point, thereby quickly Construct point cloud feature outline and finally get the ship profile. The example verified that this method can quickly and accurately generate the ship profile and provide a brand new technical measure for the ship profile measurement.
