Exhibiting at the International Drone Exhibition! We will inspect damages such as cracks in bridges using drones.
Inspection Support Technology Performance Catalog Technical Number: BR010015-V0524
Using "drone and pole camera technologies compatible with non-GNSS environments," we support close visual inspections of infrastructure structures such as bridges!
A drone capable of autonomous flight without relying on GNSS uses a pole camera that can extend up to 11 meters to capture images of infrastructure structures (architecture and civil engineering). It extracts damage and creates damage diagrams through image analysis technology (AI and manual). Additionally, we can create three-dimensional models of structures and generate orthomosaic images according to customer requests. 【Ministry of Land, Infrastructure, Transport and Tourism Listed Inspection Support Technology Performance Catalog Adoption Record】 - Structural inspections (architecture, civil engineering, equipment): 240 cases - Among them, bridge inspection records: 49 bridges (19 prefectures) (Ministry of Land, Infrastructure, Transport and Tourism: 26 bridges, prefectures: 12 bridges, municipalities: 11 bridges ⇒ Aichi Prefecture: 13 bridges) 【Deliverables】 Captured images, damage photos (composite images/damage display), damage diagrams * Depending on requests, we can provide image layout diagrams, three-dimensional models, etc. 【Exhibition Information】 ■ Maintenance and Resilience TOKYO 2024 - International Drone Exhibition - 〇 Date: July 24 (Wed) - 26 (Fri) 〇 Venue: Tokyo Big Sight East Exhibition Hall 〇 Exhibitor Seminar: July 24 (Wed) 11:00 - 11:50 JDC Forum: July 26 (Fri) 12:10 - 12:30 Theme: Advanced management of bridges, aqueducts, etc. using a three-dimensional inspection ledger.

basic information
**Benefits of Introduction** 1. Reduction and efficiency of fieldwork time ⇒ Reduction of "chalking" and "sketching tasks" 2. Improvement of safety performance ⇒ Reduction of high-altitude work using rope access or bridge inspection vehicles ※ No need for anchor installation on walls during rope access 3. Expansion of surveyable areas ⇒ Enables inspection of bridges where the installation of high-altitude work vehicles and bridge inspection vehicles is difficult 4. Mitigation of social impact and simplification of administrative procedures ⇒ No need for traffic regulations associated with bridge inspections (such as during bridge inspection vehicle operations) 5. All components can be digitized into image data ⇒ Full-area photography of the inspection target allows for data storage of the conditions at that time Information sharing and handover to workers who have not been on-site is possible Easy observation of changes during regular inspections and comparisons after disasters 6. Efficiency through AI image analysis ⇒ Accurate identification and measurement of the location and scale of deformations (cracks, peeling, etc.) Damage can be overlaid on images, allowing for precise understanding of damage locations 7. Centralized management of inspection results on a 3D model ⇒ Reduction of unnecessary resources through data management Objective understanding of damage locations through inspection record verification management

Company information
Our company was established in May 1963 in Toyohashi City, Aichi Prefecture, specializing in waterproofing, painting (at that time plastering), and flooring construction. We have inherited the spirit of our founding management philosophy: "To contribute to society through the creation of new value, aiming for diversification and internationalization as a collective of experts. By leveraging our refined skills and cultivated knowledge, or 'wisdom,' we aim to create broad demand, respond to customer needs, and consolidate our employees' overall capabilities to expand into a highly profitable enterprise." We have started new businesses that serve as pillars by aligning our philosophy with the trends of the times. Since 2014, we have established a development room within Sanshin Building Materials Co., Ltd., promoting the use of drones as a next-generation inspection system. Additionally, we are advancing joint research and development with venture companies and universities on ultrasonic inspection devices that do not require sound inspection by skilled workers, as well as the exterior wall inspection lifting robot "NOBORIN." We have participated in various advanced technology demonstrations hosted by the Ministry of Land, Infrastructure, Transport and Tourism, and our activities have been recognized, earning us the "Regional Future Leading Company" certification from the Minister of Economy, Trade and Industry. We will continue to strive to be a company that contributes to society through the creation of new value, in line with our philosophy.
