摘要:
提出了一种小波域内基于块的路面破损检测算法.路面图像经过去噪、增强等预处理后,通过hear小波变换,在最高层中对近似分量进行自适应阈值分割得到路面破损的初始区域.在其他各层中,从高层到低层依次只针对路面破损区域进一步分块分割处理,得到路面破损的准确检测.仿真实验表明,提出的算法可以很好地克服噪声影响,对不同的路面破损类型,都具有很好的路面破损分割效果.
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.
