| Abstract: | According to the actual demand of the laser projection keyboard, combined with embedded technology and image processing technology, the study design a set of laser projection virtual keyboard devices. The hardware module based on ARM Cortex-M4 architecture microprocessor as the main controller, using digital CMOS camera; and the processing of software module using MATLAB to process the digital image processing and the results are introduced into the microcontroller. After the hardware and software design of the system, the function of the whole system is tested, and the results show that the system can achieve the expected goal. |
