The present disclosure relates to systems and methods for operation retry. The system may determine whether a retry is allowed for a target operation based on a retry strategy included in a retry proxy component. In response to determining that the retry is allowed for the target operation, the system may execute the target operation. The system may detect whether there is an exception associated with the execution of the target operation. In response to determining that there is the exception associated with the execution of the target operation, the system may determine whether a retry is needed for the target operation based on the retry strategy. In response to determining that the retry is unneeded for the target operation, the system may stop the target operation.

Systems and methods for operation retry

The present disclosure relates to systems and methods for vehicle management. The systems may perform the methods to obtain information associated with a vehicle in a first time period; determine an income value associated with the vehicle in a second time period based on the information associated with the vehicle; determine a cost value associated with the vehicle in the second time period based on the income value and the information associated with the vehicle; and generate a recommendation as to whether to discard the vehicle based on the income value and the cost value.

Methods and systems for vehicle management

An inspection method and system for inspecting whether there is any liquor in goods is provided. The method includes: acquiring a radiation image of goods being inspected; processing on the radiation image to obtain an ROI; inspecting on the ROI using a liquor goods inspection model to determine if the ROI of the radiation image contains liquor goods. The above solution performs liquor inspection on scanned images of goods, especially containers, so as to intelligently assist the image inspectors.

Inspection methods and systems

The present disclosure discloses a method and system for inspecting cargoes. The method comprises: acquiring a transmission image of the inspected cargoes; processing the transmission image to acquire an interested region; extracting features from the interested region, and determining cargo information of the inspected cargoes according to the extracted features; and providing a proposed treatment suggestion of the cargoes based on the determined cargo information and at least a part of information in a manifest. The above solution can facilitate an image judgment person to accurately judge whether the concerned cargoes are allowed to pass.

Systems and methods for inspecting cargoes

A stereoscopic imaging system and method is disclosed. In one aspect the system includes an X-ray source that emits a plurality of X-ray fanbeams. The system includes columns of detectors. Each column of detectors is arranged at a preset angle with respect to the X-ray source. The detectors detect a strength of an X-ray fanbeam penetrating an object under inspection. The detectors form transmission images when the object intersects, or moves along a direction intersecting with, the X-ray fanbeams. The system includes a reconstruction apparatus that uses any two of the formed transmission images as a binocular image. The reconstruction apparatus calculates depth information of the object on the transmission images. The reconstruction apparatus superposes and fuses the calculated depth information to obtain 3D information. The reconstruction apparatus performs 3D reconstruction so that the detected object can be presented in a stereoscopic manner from different view angles.
