Basic analysis of overseas maintenance inspection education utilizing SfM technology ～A study targeting Chinese University Students～

Abstract

In Japan, maintenance of existing bridges has become increasingly important due to the increase of aging bridges. Inspection technicians regularly visit bridge locations to conduct visual inspections of bridge damage to ensure that the damage is recognized and recorded. However, the results of visual inspections for the same location vary depending on the experience of the inspectors. In developing countries abroad, the maintenance and management sector has not been prioritized and there are deficiencies in the number, experience and capacity of bridge inspectors. With the spread of DX technology in the global infrastructure sector, there is a growing expectation for more advanced, efficient and cost-effective training of maintenance and management personnel using BIM/CIM. In this study, a three-dimensional model was created using the SfM methodology, and a number of Chinese university students were educated to conduct online inspection. Finally, questionnaire and discussion were conducted to examine the validity of maintenance and management talent training. The results showed that the method was effective.
