Investigation of changes in ports and marine structures from a ship using images! The behavior of waves can be suppressed with a posture control device, allowing for clear photography!
The "Swing Control Type Onboard Inspection System" is a system that allows for the accurate inspection of the deterioration state of concrete structures such as port facilities by capturing images using a digital video camera and its attitude control device from a swinging small vessel. The system automatically obtains still images or videos through dedicated software, enabling the precise inspection of issues like cracks in the structures. By converting the obtained image data into deterioration and deformation development diagrams and inputting them into our developed "CrackDraw21," detailed facility management can be performed, including condition verification of the equipment and analysis of deterioration and deformation characteristics, making it easier to respond to assessments of structural integrity after large-scale earthquakes. 【Features】 ■ The attitude control device cancels out the camera's rolling, pitching, yawing, and vertical movements. ■ Significant cost reduction is possible, including a reduction in work time compared to conventional methods. ■ High accuracy in location information and crack shape/width. ■ On-site work is highly efficient as it only involves image capture by the vessel. *For more details, please refer to the PDF document or feel free to contact us.
