most often use when present live teaching class or interdynamic to write blackboard blank, write the writing board and show content for everybody, the content can not enlarge and dwindle rotatory removal and inconvenient save the electronic data again to the efficiency and the experience of live teaching class and interdynamic have been reduced to a certain extent.

Disclosure of Invention

The invention aims to provide a system for operating air writing based on a media application, which aims to solve the problems that most of the prior live-broadcast teaching lessons or interaction frequently use a writing blackboard white board and a writing hand board to show contents for people, the contents cannot be amplified or reduced, rotate and move, and electronic data is inconvenient to store, so that the efficiency and experience of live-broadcast teaching lessons and interaction are reduced to a certain extent.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a system for write in air of operating based on media uses, includes optical technology write and gesture tracking processing module, optical technology write and gesture tracking processing module both way junction has treater and image acquisition module, image acquisition module both way junction has the treater, treater both way junction has the internet, internet both way junction has television terminal, computer terminal and cell-phone terminal.

As a preferred technical solution of the present invention, the optical technical writing and gesture tracking processing module includes an optical technical analysis module and an input end of a gesture analysis module, an output end of the optical technical analysis module is electrically connected to a signal receiving data unit and an input end of an optical position unit, an output end of the signal receiving data unit is electrically connected to an input end of a parameter operation unit, and an output end of the optical position unit is electrically connected to an input end of a position movement operation unit.

As a preferred technical solution of the present invention, an output end of the gesture analysis module is electrically connected to a gesture tracking unit and an input end of a gesture recognition unit, an output end of the gesture tracking unit is electrically connected to a position movement operation input end, and an output end of the gesture recognition unit is electrically connected to an input end of the gesture recognition operation unit.

Compared with the prior art, the invention has the beneficial effects that:

according to the invention, the image acquisition module, the optical technology writing and gesture tracking processing module and the processor are arranged to attach a container for drawing a graph to a live image, so that the purposes of writing in the air by controlling the optical technology similar to an optical track through a script, gesture tracking and recognition operations are achieved, and the control of writing or drawing contents such as electronic data storage, amplification, reduction and rotation is achieved, so that the problems that most of the existing live teaching lessons or interactions often use a writing blackboard and a writing handwriting board to show contents for people, the contents cannot be amplified, reduced, rotated and moved, and the electronic data is inconvenient to store are solved, and the efficiency and experience of the live teaching lessons and the interactions are reduced to a certain extent.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution for operating a system for over-the-air writing based on media application: the optical technology writing and gesture tracking processing module is connected with the processor and the image acquisition module in a two-way mode, the image acquisition module is connected with the processor in a two-way mode, the processor is connected with the internet in a two-way mode, and the internet is connected with the television terminal, the computer terminal and the mobile phone terminal in a two-way mode.

The optical technical writing and gesture tracking processing module comprises an optical technical analysis module and a gesture analysis module input end, the output end of the optical technical analysis module is electrically connected with a signal receiving data unit and an optical position unit input end, the output end of the signal receiving data unit is electrically connected with a parameter operation unit input end, and the output end of the optical position unit is electrically connected with a position moving operation unit input end.

The output end of the gesture analysis module is electrically connected with a gesture tracking unit and a gesture recognition unit input end, the output end of the gesture tracking unit is electrically connected with a position movement operation input end, the output end of the gesture recognition unit is electrically connected with a gesture recognition operation unit input end, the signal receiving data unit is used for receiving the parameters of the anchor operation command line, the optical position unit is used for acquiring the position of the signal lamp pen, the gesture tracking unit is used for acquiring the position movement of the signal lamp pen, the optical position unit is combined to acquire the optimal position and the movement consistency rate, and the gesture recognition unit is used for receiving the anchor gesture recognition operation signals.
