基于FPGA的激光笔辅助教学系统设计与实现
Design and Implementation of Laser Pointer Instruction-Aided System Based on FPGA
摘要
Abstract
Based on the commonly used OV9650 camera module and 315 MHz wireless transceiver module, a design of interactive system with FPGA to implement the interaction between a laser pointer and the projected display on a large screen was adopted.The digital signal obtained by the OV9650 camera module and the wireless signal received by the 315 MHz wireless receiver module is processed and cached by FPGA.Then FPGA figures out the coordinates of the laser spot and sends the coordinates and the received wireless signal to the computer.The software on the computer processes the information to realize the interaction between the laser pointer and the projected display on a large screen.At present, this system has been applied in some classroom called smart classroom in Shanghai Jiaotong University.关键词
