This paper introduces an image quality assessment on a 3D modeling to grasp the internal state of the nuclear reactor for a decommissioning of the Fukushima Daiichi Nuclear Power Station. We try a quantitative evaluation of videos or images acquired by the investigation inside the primary containment vessels and the reactor buildings for an efficient 3D reconstruction. Finally, we aim to develop a rapid 3D reconstruction method based on the image quality assessment.
