The invention discloses a concrete dam crack inspection method based on a light and small unmanned aerial vehicle. The method includes: using a portable light and small unmanned aerial vehicle to quickly inspect cracks of a concrete dam body, taking image information and the corresponding positioning information, distance information and unmanned aerial vehicle attitude information as source data,training a crack recognition machine learning model, and using the trained crack recognition machine learning model for recognizing the cracks. Compared with a traditional mode, the inspection methodremarkably improves the inspection speed and precision, and a new method can be provided for dam safety inspection.

    本发明公开了一种基于轻小型无人机的混凝土坝裂缝检查方法,利用便携式轻小型无人机快速检查混凝土坝体裂缝,以图像信息和其对应的定位信息、距离信息、无人机姿态信息为源数据,对裂缝识别机器学习模型进行训练,将训练好的裂缝识别机器学习模型用于识别裂缝,相比传统方式,显著提升了检查速度和精确度,可以为大坝安全检查提供一种新方法。
