Embodiment 1
[0063] A video signal transmission method based on column data, specifically comprising the following steps:
[0064] S1. Obtain the X-ray machine video stream sent by the X-ray machine scanning the package;
[0065] S2. Get the moving speed of the package;
[0066] S3. According to the moving speed of the package, the X-ray machine video stream is cut to obtain current column data;
[0067] S4. Send the current column data to the image judgment terminal, so that the image judgment terminal performs paste processing according to the current column data to obtain the video frame picture currently to be displayed, and display it.
[0068] The shearing process specifically includes the following steps:
[0069] Extract a frame of video frame picture to be cut according to the X-ray machine video stream;
[0070] obtain a clipping area according to the moving speed of the package;
[0071] Cut the video frame picture to be cut according to the cut area to obtain current column...

[0127] A video signal transmission system based on column data transmission, comprising:
[0128] one or more processors;
[0129] A storage unit for storing one or more programs that, when executed by the one or more processors, enable the one or more processors to implement the one or more column-based programs A video signal transmission method of data, the one or more programs comprising:
[0130] The receiving module is used to obtain the X-ray machine video stream sent by the X-ray machine scanning the package;
[0131] Speed module, used to get the moving speed of the package;
[0132] a cutting module, configured to cut the video stream of the X-ray machine according to the moving speed of the package to obtain current column data;
[0133] The sending module is configured to send the current column data to the image judgment terminal, so that the judgment terminal performs paste processing according to the current column data to obtain the video frame picture cur...
Embodiment 4
[0135] A picture judgment terminal, comprising:
[0136] one or more processors;
[0137] A storage unit for storing one or more programs that, when executed by the one or more processors, enable the one or more processors to implement the one or more column-based programs A video signal transmission method of data, the one or more programs comprising:
[0138] receiving the current column data;
[0139] The pasting process is performed according to the current column data to obtain the video frame picture currently to be displayed, and display it.
