specific Embodiment 1

[0030] When the signal processing system detects that there is writing on the writing medium through the position detection module, the camera is controlled not to shoot; when the signal processing system detects that the writing on the writing medium leaves through the position detection module, the camera is controlled to shoot. Through the above design, the continuous work of the camera can be avoided, thereby reducing the data processing amount of the signal processing system.

specific Embodiment 2

[0032] The camera system also includes a remote controller, the remote controller is provided with a signal processing system, and the signal processing system is connected to a communication module; the remote controller is provided with a shooting key, which can control the signal processing system to send shooting instructions to the signal processing system through the communication module, After receiving the shooting instruction, the signal processing system controls the shooting situation of the camera. This design gives the user a certain degree of autonomy, and the user can independently choose whether to obtain image data through shooting for correction and fusion.

specific Embodiment 3

[0034] The signal processing system is provided with a time module, and the signal processing system periodically controls the camera to shoot according to the time module. Preferably, one picture is taken every 1-2 minutes. This design, on the one hand, can solve the problem that the camera continues to work and has more image data, and on the other hand, it can avoid the problem that the camera misses taking pictures due to the position detection module detecting the presence or absence of writing objects incorrectly.

[0035] Of course, you can also take pictures during the writing process. The signal processing system can identify the characteristic information of the written object according to the image data sent by the camera, such as color and type, and integrate the characteristic information of the written object into the content of the writing on the blackboard. For example, the writing object is red, and the track color in the generated blackboard content is also ...

Abstract

The blackboard writing correction and fusion system based on a position detection module and a camera relates to the field of electronic equipment, and includes a blackboard writing information acquisition system based on a position detection module. The blackboard information acquisition system includes a position detection module and a signal processing system. The position detection module is connected to a signal A processing system, the signal processing system collects information including the presence or absence of written objects on the writing carrying medium and the movement track of the writing objects on the writing carrying medium through the position detection module; it also includes a camera-based camera system, the The camera system includes a camera, the camera is connected to the signal processing system, and the camera faces the writing carrier medium; the signal processing system shoots the picture content on the writing carrier medium through the camera; the signal processing system will write After comparing and merging the movement track of the written object on the carrying medium and the picture content on the writing carrying medium, blackboard writing content is generated.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to blackboard writing recognition equipment. Background technique [0002] Blackboard writing may be used in meetings, training, and teaching. At present, the content of blackboard writing on the writing carrier medium can be obtained through the position detection module, but only through the position detection module to obtain the content of the blackboard writing, the method is single, and it is difficult to compare the obtained data, which is not conducive to the accuracy of the data. Contents of the invention [0003] The object of the present invention is to provide a blackboard writing correction and fusion system based on a position detection module and a camera to solve at least the above technical problems. [0004] The technical problem solved by the present invention can adopt following technical scheme to realize: [0005] The blackboard writing correction fusion...
