Embodiment

[0033] like figure 1 , 2 As shown, the PPT sketching device based on infrared image recognition in this embodiment includes a wireless remote control pen 1 , an infrared camera 2 and an image processor 3 .

[0034]The top of the wireless remote control pen 1 is provided with a visible red laser emitter 1.1 and an infrared laser emitter 1.2, the visible red laser emitter 1.1 can emit red light visible to the naked eye, and the infrared laser emitter 1.2 can emit infrared laser with a characteristic wavelength; The visible red laser emitter and the infrared laser emitter are installed in parallel. The wireless remote control pen is also provided with a red light switch 1.3 and a drawing button 1.4. When the red light switch 1.3 is pressed, the visible red laser emitter 1.1 emits visible red light; when the red light switch 1.3 is double-clicked, the visible red laser emitter 1.1 emits visible red light and keeps on until the red light switch 1.3 is double-clicked again to turn...

Abstract

The invention belongs to the field of computers, discloses a PPT drawing device and method based on infrared image recognition, reserves the use habit of a PPT page turning pen, and solves the problems that a gyroscope device is unaccustomed and translation cannot be detected. The device comprises a wireless remote control pen, an infrared camera and an image processor, the wireless remote controlpen is provided with a visible red light laser emitter, an infrared laser emitter, a red light switch and a sketching key; the wireless remote control pen sends a sketching signal to the computer; the image processor receives and processes the images shot by the infrared camera, extracts the coordinates of the infrared light spots and sends the coordinates to the computer; when the computer receives the sketching signal, the left key of the mouse is controlled to be pressed down while the PPT painting brush is started; when the computer receives the infrared light spot coordinates transmittedby the image processor, the mouse is controlled to move, and traces are drawn.

Description

technical field [0001] The invention relates to the field of computers, in particular to a PPT drawing device and a PPT drawing method based on infrared image recognition. Background technique [0002] Media technology is widely used in teachers' teaching. It transforms the originally complex and abstract change process into a more intuitive image, making it easier for the audience to understand and absorb. In the process of using multimedia technology to teach, the human-computer interaction technology of laser pointer integrated image processing, pattern recognition and other technologies to complete interactive instructions has the advantage of getting rid of the distance limitation of desktop computing mode, increasing the mobile flexibility of interaction and natural Universality has become an essential teaching aid for almost every teacher. The traditional laser pointer can realize page turning and laser function. However, with the rapid development of multimedia tea...
