1. A checking system based on a millimeter wave security inspection device, comprising:
a background service system comprising at least one server for a checking system based on a millimeter wave security inspection device;
a switching system, configured to perform a data communication; and
a security inspection instrument, connected to the server through the switching system, and configured to scan an object to obtain a scanned image, perform an automatic threat recognition (ATR) image interpretation on the scanned image to obtain an ATR image interpretation result, and upload the scanned image and the ATR image interpretation result to the server,
wherein the server comprises a memory and a processor, the memory storing instructions, and the instructions, when executed by the processor, causing the processor to:
receive a scanned image of an object and an ATR image interpretation result of the object from the security inspection instrument, wherein the ATR image interpretation result is obtained by the security inspection instrument performing an automatic threat recognition (ATR) image interpretation on the scanned image, and
cause a manual inspection task to be performed on the object and perform an image interpretation task on the scanned image according to a working mode, wherein the working mode indicates whether the checking system is provided with a manual inspection station and an image interpretation station,
wherein the processor is further configured to:
determine whether there are available manual inspection stations in the checking system when the working mode indicates that the checking system is provided with a manual inspection station but is not provided with an image interpretation station, and assign the manual inspection task for the object, the scanned image and the ATR image interpretation result to one manual inspection station selected from the available manual inspection stations, when it is determined that there are available manual inspection stations in the checking system,
transmit information of the selected manual inspection station to the security inspection instrument, and
receive a manual inspection result from the manual inspection station, wherein the manual inspection result is generated by the manual inspection station performing the manual inspection task on the object according to the scanned image and the ATR image interpretation result in response to receiving the assigned manual inspection task,
wherein the security inspection instrument, the manual inspection station, and the image interpretation station are connected to the background service system, the background service system is configured to store the scanned image, the image interpretation result and the manual inspection result, and distribute and uniformly inquire the scanned image, the image interpretation result and the manual inspection result; the background service system is configured to automatically assign the manual inspection station and the image interpretation station according to a set assignment strategy after a scanning of the object is completed, so that the manual inspection station and the image interpretation station is reused; and the background service system is configured to dynamically adjust numbers of manual inspection stations and image interpretation stations when a traffic of the object changes, and
wherein the manual inspection task for the object and the image interpretation task for the scanned image are performed simultaneously.
