US 12,688,636 B2 · Method of generating image data for dangerous object detection and imaging system using the same

Abstract

Disclosed is an image data generating method. Operations of emitting electromagnetic waves to an object and receiving scan signals scanning the object are performed by using a multi-static transceiver. First image data of a low resolution are generated based on the scan signals. when a first condition associated with the first image data is satisfied, second image data of a high resolution associated with a sub-region of the first image data are generated. When a second condition associated with the second image is satisfied, third image data based on the first image data and the second image data are generated.

Dependent claims

An image data generating method comprising:

performing operations of emitting electromagnetic waves to an object and receiving scan signals scanning the object, by using an electromagnetic wave transceiver;
generating first image data of a low resolution based on the scan signals;
generating second image data of a high resolution associated with a sub-region of the first image data when at least one of a suspicious object and a target object candidate is detected in the sub-region;
and
detecting, from the second image data, a final target object different from both the suspicious object and the target object candidate.

2 more elements

An imaging system comprising:

an electromagnetic wave transceiver configured to emit electromagnetic waves to an object and to receive scan signals scanning the object;
and
an image data generating device configured to generate synthetic image data based on the scan signals,
wherein the image data generating device is configured to:
generate first image data of a low resolution based on the scan signals;
generate second image data of a high resolution associated with a sub-region of the first image data when at least one of a suspicious object and a target object candidate is detected in the sub-region;
and
detect a final target object different from both the suspicious object and the target object candidate.
