P10. Road Cracking Area Percentage Evaluation Using Airborne Hyperspectral Imagery, Boyu Feng
P10. Road Cracking Area Percentage Evaluation Using Airborne Hyperspectral Imagery, Boyu Feng
Western Research Forum
Background:
Although the airborne platform is efficient and economic compared to the popular ground vehicles in road condition survey (RCS), studies on applying it in RCS are limited. A former study on airborne hyperspectral imagery (AHI) tried to tie a band ratio to pavement condition index. Its result proved the value in AHI, yet pointed out the difficulty in quantitative evaluation.
Methods:
This study further explored the application of AHI in RCS, and fully took advantage of the entire spectrum shape, rather than a ratio. Aiming at the cracking area percentage (CAP) on the asphalt paved arterial road system in …
