METHOD AND DEVICES FOR ASSESSING THE THREAT STATUS OF AN ARTICLE AT A SECURITY CHECK POINT

摘要

A method, an apparatus and a system are provided for assessing at a security checkpoint the threat status of a liquid product, where the liquid product is comprised of a bottle at least partially filled with liquid. X-ray image data conveying an image of the bottle holding the liquid is received, the X-ray image data being derived by performing an X-ray scan of the liquid product at a security checkpoint using an X-ray imaging apparatus. The X-ray image data is processed to derive information conveying a level of fill of the bottle by taking into account location information associated with a meniscus formed by the liquid in the bottle. The threat status of the liquid product is derived at least in part based on the level of fill of the bottle. Information conveying the determined threat status of the liquid product is released.
