Investigation of concrete structures using images! Also addressing the assessment of integrity after a major earthquake!
The "Remote Automatic Imaging System" is a system that accurately detects deterioration and deformation such as cracks and leaks by visualizing the condition of structural surfaces. Using a digital video camera or digital camera, telephoto lens, and automatic pan-tilt head, it automatically captures images of concrete structures such as dams, bridge piers, and buildings from a distance. The obtained image data is converted into deterioration and deformation development diagrams and input into CrackDraw21, which we developed. This enables detailed equipment management, such as checking the condition of social infrastructure and analyzing deterioration and deformation characteristics. 【Features】 ■ Capable of investigating areas that cannot be inspected visually ■ Can survey a wide area in a short time ■ Improved safety due to non-contact inspection ■ Significant reduction in work time compared to temporary setups ■ Quantitative comparisons before and after large-scale earthquakes are possible *For more details, please refer to the PDF document or feel free to contact us.
