Detecting foreign object debris (FOD) is provided. The method comprises receiving images captured by a number of imaging devices in a defined inspection area. A generative artificial intelligence (AI) model generates a natural language text caption describing the images. A text classifier AI model classifies FOD in the images based on the natural language text caption. An explainable AI model identifies words and phrases within the natural language text caption according to which the text classifier AI model made the classification. A report is displayed in a user interface, wherein for each identified FOD the report includes a location where the FOD was identified in the inspection area, the captured image with the natural language text caption, and highlighting of the key words and phrases identified by the explainable AI model. A generative AI translation model can then translate the report into a specified second language.
