Method and system for performing inspection of a liquid product at a security checkpoint

摘要

A method, an apparatus and a system are provided for assessing at a security checkpoint the threat status of a liquid product comprised of a bottle at least partially filled with liquid. Generally, an X-ray image of the liquid product is obtained and processed to derive a level of fill of the bottle and the threat status of the liquid product is determined at least in part based on the level of fill of the bottle. In some examples presented, an X-ray image of the liquid product is processed to derive location information associated with a meniscus formed by the liquid in the bottle and an estimated length of a path followed by X-rays through the liquid held in the bottle is used to determine the threat status of the liquid product, the length of the path being derived in part based on the location information.

主权项

1. A method for assessing a threat status of a liquid product at a security checkpoint, the liquid product being comprised of a bottle holding a liquid, wherein the bottle is at least partially filled with liquid, the method comprising:
a) receiving image data associated with the liquid product conveying an image of the liquid product, the image data being derived by performing a scan of the liquid product at the security checkpoint using an imaging apparatus that uses penetrating radiation; b) processing the image data to derive information conveying a level of fill of the bottle, wherein processing image data includes:
i) processing the image data to derive geometric information associated with the bottle; andii) deriving the level of fill of the bottle at least in part based on the geometric information associated with the bottle; c) determining the threat status of the liquid product at least in part based on the level of fill of the bottle; d) releasing information conveying the determined threat status of the liquid product.
