这项工作旨在解决无损检测（NDT）检测的有效性和挑战，并在不对材料或操作员造成损害的情况下提高缺陷检测。重点介绍了两种无损检测方法：脉冲热成像法和振动热成像法。本文还探讨了使用配备热成像系统的无人驾驶飞行器（UAV）进行自动空中检查的可能性。讨论了主动热成像检测飞机CFRP壁板的概念，并提出了利用无人机进行空中检测的方案，该方案可用于沿着飞机CFRP壁板的真实的实时检测。静态无损检测结果和进一步的无人机研究表明，无人机检测方法可以显着减少检测时间，成本和工作量，同时可能增加检测的概率。
This work aims to address the effectiveness and challenges of Non-Destructive Testing (NDT) inspection and improve the detection of defects without causing damage to the material or operator. It focuses on two types of NDT methods; pulsed thermography and vibrothermography. The paper also explores the possibility of performing automated aerial inspection using an unmanned aerial vehicle (UAV) provided with a thermographic imaging system. The concept of active thermography is discussed for inspecting aircraft CFRP panels along with the proposal for performing aerial inspection using the UAV for real time inspection. Static NDT results and the further UAV research indicate that the UAV inspection approach could significantly reduce the inspection time, cost, and workload, whilst potentially increasing the probability of detection.
