In order to control the start and stop of the escalator intelligently,count the number of people and detect the large stranded article at the exit of the escalator,an escalator intelligent video surveillance system based on IMX6Q processor was developed. The video capture based on V4L2 driver and video display based on Qt framework were implemented. The IMX6Q hardware codec unit VPU is used to perform the H.264 encoding and saving for video. The embedded FTP server is built to provide the transmission service of video downloading. The moving object is detected and tracked at the exit of the escalator. The intelligent detection algorithm was developed to assist the security staff for monitoring. The experimental results show that the timeliness and accuracy can meet the system requirements.%为了智能地控制手扶电梯的启停,在扶梯口进行人数统计和大件滞留物品检测,开发了一种基于IMX6Q处理器的手扶电梯智能视频监控系统.实现了基于V4L2驱动的视频采集和基于Qt的视频显示,用IMX6Q的硬件编解码单元VPU对视频进行H.264编码保存,搭建嵌入式FTP服务器提供视频下载的传输服务.在扶梯口对运动目标进行检测与跟踪,开发智能检测算法,协助安全人员监控.实验效果表明该系统的实时性和准确性符合要求.
