(1) Development of a simplified system for monitoring the airport pavement surface
This study focuses on the design and production of a measurement doll. The optimal radiating angle of the LED lighting and the photographing distance of the simulated grooving by a twin-lens camera were confirmed by an indoor test to set the conditions of the mounted devices. At the Haneda Airport, the stability enhancement of issues including the traveling guide display and illumination uniformity was verified.
(2) Development of a system for discriminating the distress on an airport pavement
(2)-1
The long length imaging process of images has a maximum width of 60 m and a maximum length of 3 km, and the image processing technique to store wide-area images DB were developed. This was based on the pavement surface images continuously shot during travel. Additionally, the function to create wide-area images and visible-light images was realized by handling shape information for road surface irregularities measured by infrared depth sensors as a continuous image.
(2)-2
masking light and surface marking was developed was and used to confirm typical cracks by using the sample data of the airport pavement surface.
Additionally, the function for detecting the deformation of irregularities was realized by infrared depth sensor data and shooting through a twin-lens camera in a standstill state. It was simultaneously confirmed that the depth sensing of less than 1cm was available even in mobile shooting. Future issues included the verification of identification accuracy and detection accuracy.
(3) Development of the management software for the airport pavement
The prototype of a user interface (UI)for a monitoring system was developed. This was used to check the distribution and deterioration of pavement surface distress with respect to age.
(4) Verification of the advancement of maintenance work
(4)-1
The inspection results of the airport pavement surface and repair record information were obtained from the airport administrator. Then, the data items and record contents were organized and conversion to the CSV format was initiated.
Additionally, the administrator was interviewed to confirm the need to avoid the closure of facilities owing to unexpected pavement damages.
Future issues include visualization of the aging effect of cracks and the overlapping of cracking ratio and pavement repair data.
(4)-2
The airport administrator was interviewed, and the contents of the current maintenance management were confirmed to abstract the key issues for consideration in the future. This included the system usage method, the storing method, the setting method for instruments, the display information for UI, and the use of lines and security.
