In Japan's social infrastructure, the proportion of buildings over 50 years old is increasing. In addition, it is predicted that the number of workers in the construction industry will decrease in the future, making proper maintenance and management of social infrastructure difficult. To solve this problem, a product model method has been proposed that manages point cloud data by structuring it in units of features and parts. It is considered necessary to develop an efficient update method for the maintenance data update method based on this proposal. Therefore, in this research, we devised a method for correcting the position of the 3D region data of each feature and a method for complementing the omission of identification, after using the technology to automatically identify features. We verified its usefulness in updating maintenance management data of road features using point cloud data acquired by Mobile Mapping System. As a result of the experiment, it was confirmed that this method can update the maintenance management data efficiently.
