摘要： An object inspection method, a display method and device. The display method comprises the steps of: using a CT imaging system to acquire fault data of a baggage under inspection; generating three-dimensional object data of each object in the baggage under inspection from the fault data; for each object, determining a semantic description at least comprising a quantifier description of the object based on the three-dimensional object data; and receiving a certain object selected by a user, and presenting the semantic description of the object while displaying a three-dimensional image of the selected object. The automatic auxiliary inspection of objects is achieved through automatic inspection and description. The object description result is a necessary supplement to human inspection, and is also a means for strengthening the human-computer interaction, thereby having great application value for reducing undetected possibility.
