Abstract
The utility model discloses a wireless pointer system based on the video identification technology and the Bluetooth transmission technology. The wireless pointer system comprises an image processor, a Bluetooth receiver, a camera, a projection screen and an operating rod. The image processor is respectively connected with the Bluetooth receiver and the camera. The operating rod comprises an interior single chip microcomputer, a touch switch, a proximity switch sensor and a Bluetooth emitting module, wherein the touch switch, the proximity switch sensor and the Bluetooth emitting module are connected with the single chip microcomputer. The wireless pointer system can achieve complex mouse operations, has high interactive sense and the high operational simplicity and convenience degree, and is low in cost, simple in assembly and high in university. As for the common teaching habit, namely blackboard writing, of teachers, the writing function which is not provided by an ordinary Bluetooth pointer is added into the wireless pointer system, and the requirements of teaching are met. The damage of key teaching pollutants, namely dust, to the teachers and students is reduced, and human health is protected.
Description
Technical field
The utility model relates to a kind of computing machine external input device of computer vision field and education and instruction technical field, is specially a kind of wireless teacher's pointer system based on video identification technology and Bluetooth transmission technology.
Background technology
Electronic teacher pointer is very universal on market, common electronic teacher pointer can be indicated by laser, can control computing machine or other multimedia equipments realization page turning up and down by Bluetooth transmission again, greatly facilitate the speaker, can show document or PowerPoint intuitively.Can't realize complex operations but still exist, as functions such as mouse click, cursor move, mark, write.Because existing electronic teacher pointer can only realize shirtsleeve operation, if the user wants to mark emphasis or take notes at presentation file and all to need to use mouse to finish, but can influence the teaching demonstration effect, and use mouse to mark very inconvenient also directly perceived inadequately.
The utility model content
The technical matters that the utility model solves is to provide a kind of wireless teacher's pointer system based on video identification technology and Bluetooth transmission technology, to solve the problem that proposes in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of wireless teacher's pointer system based on video identification technology and Bluetooth transmission technology comprises image processor, Bluetooth Receiver, camera, projection screen and hook stick; Image processor connects Bluetooth Receiver and camera respectively; Described hook stick comprises inner single-chip microcomputer and coupled soft-touch control, nearly switch sensor and Bluetooth transmission module.
Described image processor is PC or laptop computer.
Described projection screen is metope or curtain.
Described image processor is to connect Bluetooth Receiver and camera respectively by USB.
Described single-chip microcomputer is the STC51 single-chip microcomputer, and STC51 single-chip microcomputer and Bluetooth transmission module are passed through serial communication.
Described soft-touch control has two, is arranged on the hook stick surface.
Described nearly switch sensor is arranged on the hook stick tip.
Compared with prior art, the beneficial effects of the utility model are: native system can be realized more complicated mouse action, has stronger mutual sense and degree easy and simple to handle.
1, image processor and host computer are PC or the laptop computers of classroom or meeting room, and system only need increase a camera, bluetooth module and hook stick can realize that cost is low, and assembling is simple.
2, system can be used for any metope or curtain with better reflection strength, and highly versatile is compared with superhuge touch-screen, and versatility is higher, cost reduces greatly.
3, the teaching custom of using always for the teacher (writing writing on the blackboard), native system has added the writing function that general bluetooth teacher's pointer does not have together, more presses close to teaching.
4, reduce the harm of teaching major pollutants (dust) to Faculty and Students, protected health.

Embodiment
In order to make realization technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of wireless teacher's pointer system based on video identification technology and Bluetooth transmission technology comprises image processor 1, Bluetooth Receiver 2, camera 3, projection screen 4 and hook stick 5; PC or laptop computer that described image processor 1 is classroom or meeting room; Image processor 1 connects Bluetooth Receiver 2 and camera 3 by USB respectively; As shown in Figure 2, described hook stick 5 comprises inner STC51 single-chip microcomputer and coupled soft-touch control, nearly switch sensor and Bluetooth transmission module, described STC51 single-chip microcomputer and Bluetooth transmission module are passed through serial communication, soft-touch control has two, be arranged on hook stick 5 surfaces, nearly switch sensor is arranged on hook stick 5 tips.
Principle of work of the present utility model is: the user is by using hook stick 5 touching projection screens 4, and soft-touch control produces the saltus step level, STC51 Single-chip Controlling Bluetooth transmission module firing order information, and bluetooth receiver module 2 monitors instruction; Image processor 1 obtains the image of full projection screen 4 by camera; Image processor 1 is used OpenCV as the image handling implement then, obtains the position of hook stick 5 by the gray scale comparison algorithm, by the edge detection algorithm, obtains the edge flexional again, distinguishes the tip; Be mapped in the X-Y coordinate of projection screen 4 frames composition by algorithm then, (X1 Y1), changes API by calling mouse coordinates, and mouse beacon moves to obtain hook stick 5 tip location; The user is keeping under the touching state, soft-touch control on the clicking operation rod 5, desire realizes the left button operation, the STC51 Single-chip Controlling Bluetooth transmission module firing order information of hook stick 5 inside, bluetooth receiver module 2 monitors instruction (as shown in Figure 3), and image processor 1 is realized operation by calling mouse left click API.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
