The digital camera structural inspection system "AutoCIMA" automatically captures ultra-high-definition images using a digital camera, targeting concrete surfaces such as the underside of bridges and bridge piers, and performs automatic crack detection from those images. As an alternative to the close visual inspection conducted by inspection engineers every five years as stipulated by regulations, the use of high-resolution camera inspection support technology (AutoCIMA) allows for enhanced sophistication and efficiency. **Features** - **Automatic Shooting**: It can automatically capture images of concrete surfaces. The images taken by the high-resolution camera have a resolution of 0.5mm/pixel. Additionally, it can capture images from a distance of up to approximately 70 meters. - **Automatic Image Stitching**: On-site, a simple automatic stitching of the captured images (about 1 minute) can be performed to confirm that there are no missed shots. The captured images can be automatically stitched together into one large panoramic image. - **Automatic Crack Detection**: For the detailed stitched images, it can automatically detect deformations such as cracks, exposed rebar, spalling, and efflorescence.

"BoltChecker" is a system composed of a display device (Android terminal) and a dedicated sensor, which allows for the non-destructive verification of the pull-out strength of anchor bolts (up to 20kN). In this system, the dedicated sensor is installed on the anchor bolt, and by introducing axial force through a dedicated ram chair, the pull-out strength of the anchor can be measured accurately. Furthermore, this measuring device can pull even when there are accessories (such as fittings) present around the anchor bolt. 【Features】 ■ Non-destructive verification of pull-out strength ■ Compatible with M16 and M20 anchors ■ Pull-out strength is indicated audibly ■ Efficient data recording is possible *For more details, please refer to the PDF materials or feel free to contact us.

The "IRI Logger Lite" is a system that collects data from a non-contact speedometer and laser displacement gauge installed on a moving vehicle, allowing for the analysis and evaluation of IRI, road surface shape, and joint step shape using analysis software. It is capable of measuring road surface data (road surface profiles) at a speed of up to 60 km/h with a 10 cm pitch. By systematizing the measurement and analysis processes and utilizing specialized software, efficient data collection and organization can be achieved. 【Features】 ■ Measurement at a speed of 60 km/h ■ Detachable measuring instruments ■ Efficient data collection ■ Calculation of road surface profiles and IRI over arbitrary sections *For more details, please refer to the PDF document or feel free to contact us.
