橋梁定期点検用デジタルツイン点検野帳の開発

For bridge inspection, miss detection of damage and/or deterioration should be avoided. In addition, the basic information must be provided to determine whether the damage or deterioration is in progress or not. In the present study, the digital twin field notebook system is developed. The system is implemented on a 2-in-1 tablet computer with VR space and enables not only to store new inspection results but also to recall the past inspection results. Furthermore, the system also provides the example of assessment based on the periodic bridge inspection guideline. Therefore, the useful information for the efficient and effective bridge maintenance can be carried out.
