Abstract

The invention discloses a method and equipment for pulling back an image in an X-ray safety inspection system, which are convenient for a user to carry out secondary inspection by an image browsed before. The equipment comprises an operation part used for leading a user input conveniently, a display used for displaying a scanned image, a memory used for storing an image captured by image capturingequipment, a buffer memory used for storing an image read from the memory, a controller and a display controller, wherein the controller is used for reading an image which is relative to an appointedrange of a command from the memory when the user inputs the command for pulling back the image through the operation part, and the display controller is used for responding the command and controlling the display to display the image in the buffer memory. In the process of pulling back the image, once the image capturing equipment captures a new image, the display controller controls the displayto display the new captured image. By utilizing the method and the equipment, the user can be convenient to pull back the scanned image without limitation, and safety inspection is convenient. In addition, in the process of pulling back the image, collection of new images can not be influenced. Furthermore, the invention allows the user to pull back the image towards the left or the right from anyposition.

Description

technical field [0001] The application relates to safety inspection, and specifically relates to a method and device for pulling back images in a safety inspection system, which is convenient for users to inspect dangerous goods and contraband. Background technique [0002] The use of X-ray radiation imaging technology as a means of safety inspection is one of the main means of use in the current item machine safety inspection system. In the continuous scanning of items, it is often found that an item is suspicious, and when you want to identify it carefully, the scanned image of the item has already slid across the screen. Re-scanning images brings a lot of trouble to the inspected and affects the passing speed of passengers. In the traditional method, you can view the scanned image by finding the image on the image query interface and then open it for browsing, but this involves many operation steps, and during this process, the scanning activity must be stopped. In cont...
