Embodiment Construction

[0040] Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings:

[0041] There are two ways to store superimposed information: information storage and full screen storage. The latter stores the entire screen image, while the former only stores the overlay content and its position information. What the present invention adopts is the method for storing complete screen images, and each pixel on the screen is all corresponding to 1 bit of random access memory (RAM) storage unit, obviously this scheme makes the display and editing of characters on the screen more flexible, but Requires a certain capacity of memory and a higher data transfer rate.

[0042] By solving the modules and key technical problems of the above invention, video data can be superimposed and synthesized. The process of this method will be described in detail with an example.

[0043] Such as figure 2 As shown, a method for synthesizing video data bas...

Abstract

The invention discloses a cognitive-technology-based video data synthesis method which belongs to the field of fault diagnosis systems of automatic systems. The method comprises the following steps of: (1) checking whether the line of a video monitoring system is normal or not; (2) carrying out data encryption and storing encrypted data into a data server of the video monitoring system; (3) implementing the positioning and the integration of video data and article electronic tag data; and (4) generating a text signal for specific characters requiring overlying in the video monitoring system by utilizing a corresponding relation of the video data and the article electronic tag data which are generated in the step (3) as well as temperature and humidity data, and meanwhile, finding the recorded text signal of the image in the data server of the video monitoring system; and comparing the two text signals. The method has the advantages of implementing the association of the video data and the data requiring overlaying, implementing data fake prevention, judging whether the line has unexpected cases or not and monitoring whether the work of monitoring flow operation staff is formal or not.

Description

technical field [0001] The invention belongs to the field of fault diagnosis systems of automation systems, and in particular relates to a method for synthesizing video data based on cognitive technology. Background technique [0002] The basic principle of video superimposition is to switch the original video information and superimposed information by controlling the high-speed analog switch, and switch the display character dot matrix data on the pixel points of the displayed characters according to the scanning sequence of the TV system. Overlay characters. The character dot matrix data is generated by the graphic dot matrix information sent to it by the single-chip microcomputer through the PC. The single-chip microcomputer and the PC communicate through the serial port. The location is controlled in real time. [0003] There is a time interval of 1000μs between two adjacent field scans of the TV, which is called "field blanking period". In TV broadcasting technology...
