Problems solved by technology

This process relies too much on human factors, and under the influence of factors such as the occurrence of real dangerous objects with a very small probability and the limited experience and fatigue of the map inspectors, it will lead to missed inspections and cause serious consequences

Embodiment Construction

[0023] The present invention is further described in conjunction with the following examples.

[0024] see figure 1 , an embodiment of the present invention provides a device for creating a three-dimensional model of an object in checked luggage, the device comprising:

[0025] The acquisition module 1 is used to acquire the tomographic data of the checked baggage by using the CT imaging system;

[0026] The first processing module 2 is configured to perform interpolation processing on the tomographic data to generate three-dimensional volume data of the checked luggage;

[0027] The second processing module 3 is used to perform multiple smoothing processes on the three-dimensional volume data;

[0028] The third processing module 4 is used to perform unsupervised segmentation on the smoothed three-dimensional volume data to obtain multiple segmented regions;

[0029] The fourth processing module 5 is configured to perform isosurface extraction on the plurality of segmented...

Abstract

The invention provides a device for creating a three-dimensional model of an object in a luggage to be inspected which includes an acquisition module for acquiring tomographic data of the luggage to be inspected using a CT imaging system; a first processing module, configured to perform interpolation processing on the sectional data to generate three-dimensional volume data of the checked luggage;a second processing module, configured to perform a plurality of smoothing processes on the three-dimensional volume data; a third processing module, configured to perform unsupervised segmentation on the smoothed three-dimensional volume data to obtain a plurality of segmented regions; a fourth processing module is used for extracting the isosurface of the plurality of divided regions and obtaining the corresponding isosurface; a fifth processing module, configured to perform three-dimensional surface division on the isosurface to form a three-dimensional model of each object in the checkedluggage.

Description

technical field [0001] The invention relates to the technical field of security inspection, in particular to a device for creating a three-dimensional model of an object in checked luggage. Background technique [0002] Perspective imaging is an important means in the field of security inspection. The typical application process is: the device performs perspective scanning and imaging of luggage items, and the map inspector passes through the map, manually marks the suspect area, and makes a semantic description of the area, such as "lighter", "A bottle of wine" and so on. This process relies too much on human factors, and under the influence of factors such as the occurrence of real dangerous objects with a very small probability, and the limited experience and fatigue of the map inspectors, it will lead to missed inspections and cause serious consequences. Contents of the invention [0003] In view of the above problems, the present invention provides a device for creat...
