Inspection Support Technology Performance Catalog Technical Number: BR010015-V0524
Support for close visual inspection of infrastructure structures such as bridges using "drone and pole camera technologies suitable for non-GNSS environments"!
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 using image analysis technology (AI and manual methods). Additionally, we can create three-dimensional models of structures and generate orthomosaic images according to customer requests. 【Ministry of Land, Infrastructure, Transport and Tourism Published Inspection Support Technology Performance Catalog Adoption Records】 - 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 ⇒ within 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) to 26 (Fri) 〇 Venue: Tokyo Big Sight East Exhibition Hall 〇 Exhibitor Seminar: July 24 (Wed) 11:00 to 11:50 JDC Forum: July 26 (Fri) 12:10 to 12:30 Theme: Enhancing management operations for bridges and aqueducts 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 and bridge inspection vehicles ※ No need for anchor installation on walls during rope access 3. Expansion of surveyable areas ⇒ 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 (during bridge inspection vehicle operations, etc.) 5. All components can be digitized into image data ⇒ Full-area photography of the inspection target range allows for the preservation of data on 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 identification of damage locations 7. Centralized management of inspection results on a 3D model ⇒ Reduction of unnecessary resources through data management Objective understanding of inspection records and damage locations is possible

Our company established its office in Toyohashi City, Aichi Prefecture, in May 1963, specializing in waterproofing, painting (at that time, plastering), and flooring work. We have inherited the spirit of our founding management philosophy, which is to "contribute to society through the creation of new value, aiming for diversification and internationalization as a group 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' collective strengths to expand into a highly profitable enterprise." We have launched new businesses that align with current trends and our philosophy. Since 2014, we have established a development room within Sanshin Building Materials Co., Ltd., promoting the use of drones as a next-generation inspection and survey system. Additionally, we are advancing joint research and development with venture companies and universities on ultrasonic inspection devices that do not require skilled workers for sound inspection, as well as the exterior wall inspection lifting robot "NOBORIN." We have participated in various advanced technology demonstrations organized 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.
