Abstract

The invention discloses a video signal transmission method and system based on column data and a graph discrimination terminal, and the method is characterized in that the method specifically comprises the following steps: S1, obtaining an X-ray machine video stream sent by an X-ray machine scanning package; s2, acquiring the moving speed of the parcel; s3, cutting the X-ray machine video stream according to the moving speed of the package to obtain current column data; and S4, sending the current column data to a picture discrimination terminal, so that the picture discrimination terminal performs pasting processing according to the current column data to obtain a current to-be-displayed video frame picture, and displays the current to-be-displayed video frame picture. According to the transmission speed of the X-ray machine conveyor belt, column data extraction is performed on the received X-ray machine video stream, and the current to-be-displayed video frame picture is displayed. The column data is newly-appearing package data of each frame, and the method is used for solving the problem that an existing X-ray machine video stream cannot meet the requirement for real-time performance.

Description

technical field [0001] The invention relates to the technical field of smart security inspection, and in particular to a video signal transmission method, system and image judgment terminal based on column data. Background technique [0002] Among the equipment at the existing security checkpoints, the X-ray machine is used for security inspection of packages. When passengers enter the station, they will put the package on it to receive the inspection of the X-ray machine. The X-ray machine outputs X-ray imaging video during the process. ; The intelligent image recognition box is responsible for identifying the contraband in the X-ray imaging video and obtaining the contraband information. Then, the intelligent image recognition box sends the processed package information to the unpacking desk, local terminal and other equipment; the intelligent image recognition box configuration terminal is a pluggable client, which is responsible for configuring the intelligent image reco...
