Support for close visual inspections using NETIS non-GPS environment compatible drones.

Active in inspections in areas where GPS cannot reach! Our technology has been registered and published in the "NETIS" and "Inspection Support Technology Performance Catalog."

The Ministry of Land, Infrastructure, Transport and Tourism is promoting the use of new technologies in regular inspections of road bridges and other structures, compiling each technology into a "Inspection Support Technology Performance Catalog." The "Inspection Support Technology Using Non-GPS Environment-Compatible Drones for Close Visual Inspections" has been included in this catalog since it was published in 2019. In October 2021, to make it usable in a wide range of sites, high-altitude photography technology using pole cameras was added in addition to drone-based close-up shooting technology. Furthermore, in June 2022, it was registered in "NETIS," which is operated by the Ministry of Land, Infrastructure, Transport and Tourism. This technology uses drones equipped with a camera that has 'self-position estimation functionality' and 'collision avoidance functionality (Visual SLAM)' to perform close-up photography of concrete components in the upper and lower structures of bridges. The captured images can automatically detect cracks through AI analysis, accurately record the width, length, and other scales and locations of damage, and allow for the creation of orthomosaic images, damage diagrams, and three-dimensional models. [Advantages of Our Technology] ■ No need for traffic regulation due to the installation of bridge inspection vehicles ■ Reduction of hazardous work at heights, such as rope access, etc.
