- Abstract:
-
A block-based pavement damage detection algorithm in wavelet domain is proposed. After preprocessing such as denoising and enhancement, the initial area of pavement damage is obtained by adaptive threshold segmentation of the approximate component in the highest layer by hearing wavelet transform. In the other layers, from the high floor to the low floor, only the pavement damage area is further divided and processed in pieces, and the pavement damage is accurately detected. Simulation experiments show that the proposed algorithm can overcome the influence of noise well, and has a good pavement damage segmentation effect for different types of pavement damage.
