초록
In the line heating for the plate forming of a ship’s hull, an in‐line assessment of completion is necessary for an automated production system. In the current curved plate forming process, a fabricated plate is compared to a template that is made in the mold loft and is used for the determination of the heating‐line for the next step. In this paper, a new method is presented for the in‐line assessment of completion for curved plate forming. This method uses a 3‐D scanner. For the registration of the scanned data for a surface and the target surface, the ICP (Iterative Closest Points) method was adopted. A computer program was developed to carry out the registration, check for similarities, visualize the surface, and control the results. This program was applied to a sample curved‐plate forming process.
Abstract
In the line heating for the plate forming of a ship’s hull, an in‐line assessment of completion is necessary for an automated production system. In the current curved plate forming process, a fabricated plate is compared to a template that is made in the mold loft and is used for the determination of the heating‐line for the next step. In this paper, a new method is presented for the in‐line assessment of completion for curved plate forming. This method uses a 3‐D scanner. For the registration of the scanned data for a surface and the target surface, the ICP (Iterative Closest Points) method was adopted. A computer program was developed to carry out the registration, check for similarities, visualize the surface, and control the results. This program was applied to a sample curved‐plate forming process.
