Abstract
Empty container identification method and system are disclosed. The method includes: obtaining customs declaration information, and finding out an vehicle declared as an empty container or an empty vehicle from the customs declaration information; performing X-ray inspection on the vehicle to acquire a transmission image of the vehicle; inputting the transmission image into an empty container identification model obtained by pre-training, so that the empty container identification model determines candidate regions of the transmission image, and performs post-processing analysis on the candidate regions to obtain an image identification result; and comparing the image identification result with the corresponding customs declaration information to determine whether or not the image identification result is consistent with the customs declaration information.
