基于机器视觉的智慧教室灯控系统设计
Design of Intelligent Classroom Lamp Control System Based on Machine Vision

提出了一种基于机器视觉的智慧教室灯控系统的设计方案，实验中，图像信息处理端采用PC机作为中央处理器，配备USB摄像头作为视频图像采集系统，将采集到的信息送入PC机进行图像处理，通过级联分类器确定出视频图片中人脸目标然后判断目标所在教室区域来实现对各区域教室灯管的开/关管理；控制端运用树莓派平台搭载Linux系统进行电器控制，接收处理器处理后的指令信息，实现对教室灯管开或关的控制。实验测试结果表明，该系统可以有效检测出人物目标并按目标所在位置控制教室灯的亮灭，对进一步实现更丰富的智慧教室灯控功能奠定了基础。
This paper presents a design scheme of intelligent classroom lamp control system based on ma-chine vision. PC is used as central processor and USB camera is used as acquisition system at the end of information processing, and the collected information is processed on PC. By determining the face target in the picture and judging the division of the classroom area, the management of the classroom lamp is realized. The embedded control terminal raspberry pie receives the instruction information processed by the processor and carries on the electrical control with the Linux system, which realizes the on or off control of classroom lamp. The experimental results show that the system can effectively detect the character target and control the lights according to the position of the target. It lays the groundwork for the further realization of intelligent classrooms with richer lamp-control functionality.
