3D Reconstruction of Structure Based on Image Sequence for Supporting Operator in Decommissioning

-Quantitative Method for Evaluating Reconstruction Accuracy of 3D Model-

Abstract

We have developed a 3D reconstruction method based on image sequences recorded by remotely operated robots for decommissioning. This paper describes the quantitative method for evaluating reconstruction accuracy of a 3D model generated by Structure from Motion. We verify the performance of the 3D reconstructed model based on an image sequence. As a result, we confirmed that the reconstruction accuracy of 3D models can be quantitatively evaluated by comparing with a 3D point cloud measured by a laser scanner as ground truth.
