摘要：Accuracy evaluation system for curved shell plates was developed. This system compares the plate design data with the point cloud data of the actual curved shell plate. Point cloud data is generated by a laser scanner with references based on the edge of the actual shell plates. Displacement errors which refer to the distances from each point in the point cloud data to the desired design surface are evaluated and visualized by color map and histogram. This developed system enables users to understand the errors on the whole surface of curved shell plates quantitatively. This accuracy evaluation system was tested on actual curved shell plates, and correlations between the distribution of the errors and the making process are illustrated in this paper.
