摘要

水下结构检测对于确保桥梁的安全性和使用寿命至关重要。为了提高这些检测的效率和准确性，本文介绍了一种通过折射校正和多摄像头校准来测量桥墩形态的方法。测量设备使用带有适当照明的水下视觉检测平台，可缓解能见度低的挑战。提出了一种基于编码标记的共面相机折射参数校准方法，以减少折射的影响，同时还开发了一个多折射校正模型。此外，还引入了一种新颖的多摄像头外校准方法来拼接点云。通过在空中和水下对两种外校准方法进行比较分析，验证了所提方法的准确性和效率。最后，成功测量了水下桥墩的圆形截面形状，并有效展示了缺陷定位结果。

Underwater bridge pier morphology measurement method via refraction correction and multi-camera calibration

Underwater structural inspection is essential for ensuring the safety and longevity of bridges. To improve the efficiency and accuracy of these inspections, this paper presents a method for measuring the morphology of bridge piers through refraction correction and multi-camera calibration. Using an underwater visual inspection platform with appropriate lighting, the measurement equipment mitigates low visibility challenges. A coplanar camera refraction parameter calibration method based on encoded markers is proposed to reduce the effects of refraction, along with the development of a multi-refraction correction model. Additionally, a novel multi-camera extrinsic calibration method is introduced to stitch point clouds. A comparative analysis of the two extrinsic calibration methods, conducted both in air and underwater, has been performed to validate the accuracy and efficiency of the proposed approach. Finally, the circular cross-section shape of the underwater bridge pier was successfully measured, and the results of defect localization were effectively presented.
