Embodiment 1

[0030] Cloud board image stitching and recording system, including cloud board 1, camera 2, cloud board screen 3, microprocessor 4, communication interface module 5, power supply, microprocessor 4 is connected to the power supply; one or more cloud boards are installed around the cloud board 1 A camera collects the cloud board pictures 3 of different viewing angles; the camera 2 is connected to the microprocessor 4, and each camera 2 transmits the captured cloud board picture 3 information to the microprocessor 4 for splicing; the microprocessor and the communication interface module 5 connection, wireless transmission to the mobile terminal, the mobile terminal sends the image data to the cloud, edge strips are set on the edge of the cloud board 1, and the vertical distance between the detection surface of the camera 2 and the whiteboard is 2-3mm.

[0031] A cloud plate image splicing and recording method is carried out according to the following steps:

[0032] Step 1. One o...

Embodiment 2

[0039] In the present invention, a camera is installed on multiple corners of the cloud board 1, four of which are taken as examples below, and white side strips are added to the edge of the cloud board. The four cameras 2 are connected with the same single-chip microcomputer 4, and the single-chip microcomputer 4 is directly connected with the power supply and the communication interface module 5. After starting to write on the cloud board, every △T camera 2 automatically records the entire cloud board picture, and stores it for future use after the microprocessor 4 splicing is completed. At the same time, when the camera 2 is set and the operator is about to wipe the cloud board, the system will also splicing the four cloud board images 3 to the microprocessor 4 before wiping, and then send the data to the host computer or the network. The upper computer or the network can upload the picture information to the cloud, and during the process of image processing, the sound will...

Abstract

The invention discloses a cloud board image splicing and recording method and system, including a cloud board, a camera, a cloud board picture, a microprocessor, and a communication interface module; one or more cameras are installed around the cloud board to collect images from different viewing angles Cloud board screen; the camera is connected to the microprocessor, and each camera transmits the captured cloud board screen information to the microprocessor for splicing; the microprocessor is connected to the communication interface module, and is wirelessly transmitted to the mobile phone, and the mobile phone sends the image The data is sent to the cloud. The invention uses electronic cloud plate infrared technology, compared with similar electromagnetic products, any object can be operated without a special pen, and has a long service life, mature technology and stability.

Description

technical field [0001] The invention belongs to the technical field of image splicing of cloud boards, and is a technology capable of sending complete images to the cloud for storage after splicing images of various viewing angles collected by the cloud board. Background technique [0002] In the field of modern teaching, the application of multimedia technology and the enhancement of interactivity are the mainstream direction of teaching development. Whether in ordinary classrooms or in educational conference halls, we can see various multimedia projection equipment or interactive teaching equipment. The electronic cloud board is an applicable tool that is most popular in traditional offline public places such as teaching and conferences. It can communicate with computers to form an interactive collaborative meeting or teaching environment. Compared with the traditional "one-wipe and disappear" blackboard, the electronic cloud board can record and save the whole process of ...
