无人机航测技术在大坝裂缝检测中的应用研究

Research on the Application of UAV Aerial Photogrammetry Technology in Dam Crack Detection

为了解决传统的大坝裂缝监测技术人工劳动强度大、安全风险较高等问题,随着机器视觉和数字图像技术的发展,非接触式监测技术应用越加广泛。本文依托具体大坝监测项目,利用消费型无人机对坝体进行了倾斜摄影测量,生产了大坝的三维模型,并在模型上提取了裂缝的空间位置信息,建立了裂缝信息数据库,为今后进一步分析和评估大坝裂缝发育状态提供基础研究数据。

In order to solve the problems of high labor intensity and high safety risk of traditional dam crack monitoring technology,with the development of machine vision and digital image technology,non-contact monitoring technology is more widely used.Relying on the specific dam monitoring project,this paper uses consumer UAVs to carry out oblique photogrammetry on the dam body,produce a three-dimensional model of the dam,extract the spatial location information of the cracks on the model,and establish a crack information database,which provides basic research data for further analysis and evaluation of the dam crack development status in the future.
