摘要:

针对目前公路路面裂缝种类和尺度多样导致路面病害检测困难的问题,提出一种基于GhostNet的轻量化无人机图像裂缝检测方法检测不同种类路面裂缝。首先,引入轻量级GhostNet中的Ghost模块优化YOLOv4主干特征提取网络,得到轻量化模型YOLOv4-Light,以降低模型复杂度,并提高裂缝检测速度;然后,在模型预测输出端融合高效通道注意力(ECA)机制,从而进一步增强裂缝特征提取能力,提高裂缝检测精度。仿真实验结果表明,所提方法与现有的YOLOv4相比,模型大小降低了82.31%,模型参数量减少了82.56%,并提高了裂缝检测效率,能够满足公路运输过程中出现的不同类型的裂缝检测需求。

Abstract:

Aiming at the difficulty of detection of pavement diseases caused by the variety of types and scales of road pavement cracks, a lightweight unmanned aerial vehicle image crack detection method based on the GhostNet was proposed for the detection of different types of cracks in pavement. First, the Ghost module in the lightweight GhostNet was introduced to optimize the YOLOv4 backbone feature extraction network, and the lightweight model YOLOv4-Light was obtained, thereby reducing the model complexity and improving the crack detection speed. Then, the Efficient Channel Attention (ECA) mechanism was integrated in the model prediction output to further enhance the crack feature extraction ability and improve the precision of crack detection. Simulation results show that compared with the existing YOLOv4, the proposed method has the model size reduced by 82.31%, the amount of model parameters reduced by 82.56%, and the crack detection efficiency improved. The method can meet the detection needs of different types of cracks during road transportation.
