An Attempting to Generation of Digest and Wide-Area Images from Unit 2 PCV Internal Investigation Video

Abstract

The video of investigation inside the primary containment vessel (PCV) of the Unit 2 of the Fukushima Dai-1 number power plant in 2019 is too long with a lot of redundant information and has a lot of focus/lighting problems. This study, in order to enhance convenience for analyzing and utilizing the video inside the PCV, attempts to implement the following modules: 1) reduction of video time (time-shortening processing), 2) extraction of impressive scenes (digest image creation), and 3) generation of wide-area (panorama) images.
