Embodiment 1

[0038]The external independent device uses TI's DSP chip and STM32 as the core processor. By manipulating the buttons of the smart ring, the light beam hits the large screen 1. Laser points with different frequencies will be generated on the large screen 1, and the camera 3 is fixed on the projection screen. Let it shoot the projection screen 1 on the projector 2, and the camera 3 fixed on the top of the projector 2 collects 30 pictures per second. After collecting each laser point image, it will be sent by the DSP processor with the WIFI module through the WIFI module. It is transmitted to DM6437 and STM32 core processors, after image processing technology, small target size adaptive detection and neural network BP algorithm processing, image acquisition, storage and processing are completed, and finally the SPI protocol and USB protocol are used to mount the WIFI module The DSP sends the final and perfect data to the PC 4 through the WIFI module, and then the PC 4 drives the ...

Abstract

The invention discloses a multimedia projection system of a wearable intelligent ring. The multimedia projection system of the wearable intelligent ring comprises an external independent device and the wearable intelligent ring, wherein the external independent device consists of a large screen, a projector, a camera and a PC (Personal Computer); the camera is fixed above the projector, can shoot the large screen and can carry out data transmission with the camera through a WIFI (Wireless Fidelity) module mounted on the camera; the wearable intelligent ring comprises the ring, wherein an upper convex part is arranged on the top of the outer part of the ring, a laser emission head is embedded in the upper convex part, the side handle of the ring is provided with a small circuit board which can be fixed on the ring; and the small circuit board is provided with a left button, a right button, a button cell and a single chip microcomputer. The multimedia projection system is small, attractive, flexible and convenient in remote operation and suitable for popularizing and applying and has various functions.

Description

technical field [0001] The invention relates to a teaching system using a novel laser pointer, in particular to a wearable intelligent ring multimedia projection system which can simulate a mouse for remote operation of a PC for multimedia teaching and collaboration meetings. Background technique [0002] At present, multimedia technology teaching is becoming more and more popular, and many electronic products at home and abroad have emerged as the times require, but these products have certain limitations in use. For example, there are wearable remote control devices on the market, which use gyroscopes for positioning and wireless transmission. Because the technology is not yet mature, the range of use is only 3-5 meters, and it concentrates all hardware devices in one control device Among them, the volume is large, the appearance is not beautiful, the service life is short, the battery life is short, and frequent charging or battery replacement is required. [0003] The ...
