基于图像处理技术的电梯门控制系统

Elevator door control system based on image processing technology

为了实现电梯门更加安全、智能地运行,开发了一种非接触式电梯门控制系统。该系统采用CMOS图像传感器OV7620作图像采集,在以ARM9芯片S3C2440作为主控制器的开发平台上,运用先进的动态图像处理算法—区域阈值差分法,对电梯门间图像进行动态检测,实现了实时地检测到需要使用电梯的人,使电梯门快速响应打开。实验结果表明,该系统的实时性、适应性都基本满足要求,具有较大的实用价值。

Aiming at achieving more secure and more intelligent,a non-contact elevator door control system was developed.A CMOS image sensor（OV7620） was used for acquisition,on ARM9 chip S3C2440 as the main controller development platform,the dynamics of advanced image processing algorithms—region threshold difference method was used.The image between the elevator door dynamic was tested,and real-time detection of people who needed to use the elevator was got,so that rapid response to open it.Experimental results show that the real-time performance and adaptability can meet all basic requirements,with a greater practical value.
