Image cutting method based on edge image recognition box, electronic equipment and medium

Abstract

The invention discloses a picture cutting method based on an edge picture recognition box, electronic equipment and a medium. The picture cutting method comprises the following steps: S1, acquiring a video stream sent by an X-ray machine; s2, intercepting each frame of video picture according to the video stream to obtain a video picture sequence; s3, according to the time sequence of the parcels entering the X-ray machine, sequentially calling video pictures corresponding to the time from the video picture sequence, carrying out cutting comparison, storing the matched video pictures into an X-ray picture set, and circulating the step S3; and S4, according to a preset rule, merging the video pictures in the X-ray picture set to obtain information of all packages in the video stream. According to the method, the parcel information is carried by using the X-ray pictures, so that compared with videos, the efficiency of massive X-ray imaging videos can be improved, key parcel information in the X-ray imaging videos can be fully embodied and excavated, meanwhile, a lower system memory is occupied, and the memory occupancy rate of the system is reduced.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for cutting images based on an edge image recognition box, electronic equipment and media. Background technique [0002] In scenes such as subways, airports, etc. entering the entrance of their facilities, there are often security checkpoints equipped with X-ray machines. Passengers transport their luggage and other carry-on items to the irradiation range of X-rays by using conveyor belts. The X-rays in the X-ray machine The light ray irradiates the package, generates X-ray imaging video, and then sends it to the image judgment terminal through DVI, HDMI, DF and other interfaces. Therefore, in the picture of the X-ray imaging video, the package is moving horizontally with the conveyor belt, from left to right or from right to left, and the packages appear one after another in the video picture. [0003] In the prior art, X-ray imaging videos containing packages are usual...

Problems solved by technology

[0003]In the prior art, X-ray imaging video containing the package is usually used to carry the package information in the security inspection scene, but there are the following disadvantages: a video Including one or more package information For one or more pictures, it is impossible to quickly and intuitively establish a person-package mapping relationship. When it is convenient for security inspectors to look back at historical information, it increases the difficulty of security inspection personnel tracking; video takes up storage space Large, inconvenient to save, video takes up huge storage space, and takes up bandwidth when transmitted on the network. At the same time, there will be a lot of redundant information between adjacent multiple frames; The image recognition system consumes a lot of computing resources
