Embodiment Construction

[0076] In order to better understand the technical solutions provided by the embodiments of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation manners.

[0077] In the prior art, the package on the conveyor belt is mainly scanned by the X-ray security inspection machine, the pseudo-color image of the package is obtained in real time, and each package is identified based on the color of the pseudo-color image, so as to realize the segmentation of the package. However, in the complex scene of interlaced parcels, the accuracy of the parcel segmentation method based on pseudo-color images is low, which further leads to low accuracy of subsequent contraband detection.

[0078] In view of this, the embodiment of the present application provides a parcel segmentation method, which can be executed by a parcel segmentation device, and the parcel segmentation equipment can be realized by a separate...

Abstract

The invention provides a parcel segmentation method and device, equipment and a medium, which are used for improving parcel segmentation accuracy. The method comprises the steps that in the security check process, radioactive light scanning is sequentially conducted on moving packages in the direction of a first coordinate axis in a space coordinate system, and if it is determined that a package subarea exists in a transillumination image area scanned at the current time, the package subarea in a scanning area scanned at the current time is determined; for every two adjacent unit areas of theparcel subarea scanned at the current time and the parcel subarea scanned at the last time in the second coordinate axis direction in the space coordinate system, if it is determined that coordinate points corresponding to the two corresponding adjacent unit areas intersect, the two corresponding adjacent unit areas are set as first marks; and if the coordinate points of the parcel subarea scannedat the current time and the parcel subarea scanned at the next time in the direction of the first coordinate axis do not have intersection, the parcel subareas marked with the first marks in each scanning are combined before the next scanning to obtain a parcel area.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a package segmentation method, device, equipment and medium. Background technique [0002] With the continuous development of computer technology, computer technology is widely used in various aspects, such as in the field of security inspection. The current security inspection method is generally as follows: a radioactive security inspection machine, such as an X-ray security inspection machine, is installed above the conveyor belt, and the package is placed on the conveyor belt. Pseudo-color image, the security inspector determines whether there are contraband in the package based on the pseudo-color image, but the real-time pseudo-color image may include multiple packages, which is easy to cause false detection or missed detection. Therefore, each security inspection package is effectively segmented It helps to improve the accuracy of contraband detection. ...
