Active thermography is a proven technology used in a wide variety of applications. In the most common approach using a static configuration, the elements involved in the inspection do not move. This presents serious drawbacks when it is applied to the inspection of large products and machines. An alternative approach is the dynamic inspection, which enables the inspection of large and complex products with better resolution, but it is also extremely challenging as data reconstruction is necessary. This work analyzes two methods for dynamic inspection using active infrared thermography: the thermal photocopier and the line scan. Automatic robust methods are proposed to calculate the temperature–time history, producing a pseudostatic sequence that can be further processed using advanced data processing algorithms to improve defect detection. Results demonstrate the robustness of the proposed methods and the ability to inspect large products with excellent results.

使用主动红外热像仪进行自动动态检查

主动热成像技术是一种已被广泛应用的成熟技术。在使用静态配置的最常见方法中,检查中涉及的元素不会移动。当将其应用于大型产品和机器的检查时,这将带来严重的缺陷。另一种方法是动态检查,可以检查分辨率更高的大型复杂产品,但由于必须进行数据重建,因此也极具挑战性。这项工作分析了使用主动红外热像仪进行动态检查的两种方法:热复印机和线扫描。提出了自动鲁棒方法来计算温度-时间历史记录,产生伪静态序列,可以使用高级数据处理算法对伪静态序列进行进一步处理以改善缺陷检测。
