First Claim
Patent Images
1. A method for inspecting a vehicle, comprising steps of:
- acquiring a unique identity number of an inspected vehicle;
carrying out X-ray scanning on the inspected vehicle to acquire an X-ray image of the inspected vehicle;
retrieving at least one historical inspected image related to the unique identity number from a historical inspection database;
determining, based on one template image selection algorithm selected from multiple template image selection algorithms, one of the at least one historical inspected image as a template image;
determining a difference region between the X-ray image and the template image;
presenting the difference region to a user, andwherein the multiple template image selection algorithms are selected from the following image processing algorithms;
an average grey minimum method, a closest time method, a grey means square error minimum method, a local template method, and a probability template method.

6. A system for inspecting a vehicle, comprising:
-
an identity (ID) acquisition unit configured to acquire a unique identity number of an inspected vehicle; a radiation imaging system configured to carry out X-ray scanning on the inspected vehicle, to acquire an X-ray image of the inspected vehicle; a storage device configured to store the X-ray image and a historical inspection database; an image processing unit configured to retrieve at least one historical inspected image related to the unique identity number from the historical inspection database, determine, based on one template image selection algorithm selected from multiple template image selection algorithms, one of the at least one historical inspected image as a template image, and determine a difference region between the X-ray image and the template image; and a display device configured to present the difference region to a user, wherein the multiple template image selection algorithms are selected from the following image processing algorithms;
an average grey minimum method, a closest time method, a grey means square error minimum method, a local template method, and a probability template method. - View Dependent Claims (7, 8, 9)
