Embodiment Construction

[0018] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components, although shown in different drawings. For clarity and conciseness, detailed descriptions of known functions and constructions incorporated herein will be omitted since they would otherwise obscure the subject matter of the present invention.

[0019] As mentioned above, the method of the embodiment of the present invention can reduce the size of the image file while ensuring the quality of the X-ray image. In this way, the same disk capacity will store more image files.

[0020] figure 2 A schematic structural diagram of a security inspection system to which a method according to an embodiment of the present invention is applied is shown.

[0021] like figure 2 As shown, in the process of carrying out the security check on the item, the...

Abstract

The invention discloses a method for compressing and saving images in a security inspection system and the security inspection system. The method comprises the following steps: acquiring a radiation image of an inspected object, including multi-column image data; removing blank areas in the radiation image except the part of the object image; and saving the image without the blank areas. By utilizing the method and the system, the data amount to be saved in the security inspection system can be remarkably reduced without reducing the image quality.

Description

technical field [0001] The invention relates to image storage in a security inspection system, in particular to an image compression storage method used in a security inspection system and the security inspection system, which can store radiation images collected with a relatively small storage capacity without image degradation quality. Background technique [0002] In general, radiation image data such as X-ray images are organized in units of columns. A column of image data refers to a linear arrangement of data received by all detector pens. like figure 1 As shown, the number of detectors of the CX100100T model safety inspection equipment is 1088*2 (each point corresponds to one high-energy and one low-energy), so a column of data will have a size of 1088*2*2 bytes. If an image has 1280 columns, the entire image size will reach 1088*2*2*1280=5570560 bytes, about 5.6M bytes. [0003] The existing X-ray image storage solution is to completely store the data collected b...
