Empty box identification method and system

Abstract

The invention discloses an empty box identification method and identification system, and the method comprises the following steps: obtaining customs clearance information, and extracting a vehicle which is declared as an empty box or an empty vehicle from the customs clearance information; performing X-ray inspection on the vehicle to obtain a transmission image of the vehicle; inputting the transmission image into an empty box recognition model obtained by pre-training, so that the empty box recognition model positions a candidate region of the transmission image, and performing post-processing analysis on the candidate region to obtain an image recognition result; and comparing the image recognition result with the corresponding customs declaration information, and judging whether the image recognition result is consistent with the customs declaration information or not. According to the empty box identification method and identification system, the transmission image of the vehicledeclared to be empty or empty is intelligently analyzed, whether the vehicle is empty or not can be accurately determined under the condition that the box is not opened, and the workload of securitycheck personnel is reduced to a great extent.

Description

technical field [0001] The present disclosure relates to the technical field of radiation imaging safety inspection, and in particular to an empty container identification method and system for safety inspection of empty containers of vehicles. Background technique [0002] As a non-invasive inspection method, X-ray transmission imaging technology is widely used in security inspection scenarios such as ports, customs, and border inspections to conduct risk assessments on vehicles passing through customs.
