【摘要】 为了进一步改善电梯轿箱内的安全性能,提高电梯群控系统的性能,该文设计了一种基于ARM的电梯轿厢内人数检测系统。检测系统以S5PV210为控制中心,搭载视频采集模块通过基于计算机视觉的人数识别算法实现轿厢内人数检测。电梯轿厢内的人数检测系统是以数字图像处理为基础,为满足轿厢内监控设备的小型化、安装便利等需求,该文采用前端识别技术。在基于ARM-Linux的嵌入式设备上实现图像采集、图像处理、采用改进的随机Hough算法人数检测算法来实现人数检测。实验表明该系统能对轿厢内的人数进行准确的计数,在检测识别和安防领域具有很好的应用前景。更多还原

【Abstract】 In order to improve the safe use of the elevator and elevator group control system,this article design a system of counting for the number of people in the elevator based on ARM.This sys tem take S5 PV210 as control center,with video capture module.This system detect number of people within the elevator car by computer vision.In order to improve miniaturization of equipment and convenience of installation,the article use front-end recognition.Acquisiting image,processing image and using improved randomized Hough transform detect number of people by embedded equipment base on ARM-linux. Plenty of experiments verify that the system can obtain number of people accurately,which would have a good application prospect in zoom of detection and identification in the future.更多还原
