計測リサーチコンサルタント List of Products and Services

This technology is a method for measuring the existing stress (strain) in concrete with high precision. It has received significant attention as a survey technique for the current condition investigation of PC bridges, and it was awarded the 18th National Land Technology Development Award. By using an optical full-field measurement method, it enables high-precision strain distribution measurements even in the micro-regions near the slit. 【Features】 ■ Measurement of the area around the slit before and after cutting using a line sensor scanner type full-field strain measurement device. ■ Inverse analysis using FEM analysis allows for the estimation of the existing stress in concrete members based on the measured released strain distribution. ■ In PC structures, it is possible to estimate the amount of prestress from the existing action stress. ■ It can also be used as documentation for the restoration design of PC bridges. *For more details, please download the PDF or contact us.

Using digital technologies such as 3D laser scanning, we support the repair and utilization of valuable cultural heritage structures, including stone walls. The 3D laser is a measuring instrument that can obtain extensive three-dimensional position coordinates and color information in a short time from a distance. Therefore, it allows for the rapid recording of the shapes and displacement measurements of large structures such as bridges and dams, as well as modern heritage sites. We also utilize high-resolution handheld scanners to create scaled models using 3D printers. 【Examples (excerpt)】 - Nogi Town Brick Kiln, Manda Mine → Shape recording, creation of general drawings → To detail the damage, photogrammetry using a remote-controlled helicopter - Gunkanjima (listed on the UNESCO World Heritage tentative list) → Using 3D lasers and an omnidirectional panoramic imaging system to record three-dimensional information and collect images of the reduced shapes.

We clarified the characteristics of the camera through indoor experiments and developed a "mobile continuous image measurement system" that does not degrade image quality. This system can manage multiple industrial area cameras along a time axis and constructs a geometric correction system to create expanded images that maintain consistent image quality from camera images with different shooting resolutions, enabling the accurate creation of expanded images on curved surfaces and bent sections. We validated this system on monorail track girders and road tunnels, confirming that it allows for "clearer image acquisition" compared to conventional video cameras, and significantly reduces the number of days required for analysis in the post-processing stage. ● For more details, please download the catalog or contact us.

A fiber optic sensor is a measurement sensor that uses optical fibers, widely used in the measurement field not only for data communication but also as sensors for strain, vibration, temperature, and more. They can be categorized into several types based on their measurement principles, each with different characteristics. However, a common representative feature of all fiber optic sensors is their immunity to electrical noise and excellent durability. With the increasing importance of monitoring and diagnosing aging structures, fiber optic sensors are gaining attention, and our company offers OSMOS sensors. ● For more details, please download the catalog or contact us.

The buried cultural property database "Yamato" consists of seven menus: site ledger, structural ledger, artifact ledger, image data, drawing data, original drawing data, and document data. Each database allows for data searches, printing, and more. In excavation surveys of sites, it is necessary to efficiently manage the vast amount of data, including artifacts unearthed during the investigation. Therefore, our company has developed a support system for centralized management of the obtained data as a database. By utilizing this system, we believe that it will lead to increased efficiency in excavation surveys, enhanced data management, and strengthened research activities. ● For more details, please download the catalog or contact us.
