  • Patent number: 12029484
    Abstract: The present disclosure provides a method of determining a distance and a height, including: measuring, a first distance, a second distance and a third distance from the security inspection device to the tested person as well as measuring a first height, a second height and a third height of the tested person; determining, a relationship between the first distance and a minimum distance threshold as well as a maximum distance threshold, a relationship between the second distance and the minimum distance threshold as well as the maximum distance threshold, and a relationship between the third distance and the minimum distance threshold as well as the maximum distance threshold; determining, a final distance from the security inspection device to the tested person and a final height of the tested person; and performing a pixel conversion and a size conversion on the pupil image of the tested person.

  • Patent number: 11169257
    Abstract: A security inspection system and a security inspection method are disclosed. The system includes: at least one inspection sub-system configured to perform ray scanning on an object to be inspected; at least one on-site image processing computer communicatively connected to the at least one inspection sub-system, and configured to store and process a radiographic image in real time; and at least one remote image processing computer communicatively connected to the at least one on-site image processing computer via at least one of a public network and a dedicated network. The at least one remote image processing computer each is configured to log in one of the at least one on-site image processing computer through remote access to synchronize remote data on a screen of the on-site image processing computer to the remote image processing computer.

  • Publication number: 20190197722
    Abstract: A security inspection system and method thereof are disclosed. At least one inspection sub-system is configured to perform a ray scanning on an object to be inspected, and obtain a radiographic image data of the object. At least one local computer is communicatively coupled to the at least one inspection sub-system, and configured to store the radiographic image data. The at least one local computer is further configured to divide the radiographic image data into a plurality of sub-regions according to a predefined pattern, store image data of respective sub-region in columns, and store information indicating relationships between respective sub-regions.
