摘　　要：针对电梯内暴力活动的日益增多,特别是针对女性的暴力活动的日益增多,电梯安全问题也越来越受到人们重视.文中探讨了一种基于计算机视觉的电梯内防暴力智能视频监控方式,通过采集电梯轿厢内的视频图像,并对获取的图像进行实时的处理和分析,通过减背景算法和跟踪算法,得到电梯轿厢内轿厢门、人体等一系列的状态信息,然后,根据预先设计的相应的电梯内暴力情景语义检测判定规则,通过检测轿厢内的人数、人体所占的面积变化、人体之间的相对距离变化、人体的运动轨迹与状态等来检测和判断是否有可疑暴力行为;为电梯使用者提供一种安全的乘坐环境.Due to the increase of the crimes happen inside elevators,the security issue is paid more and more attention by people.This paper proposes an intelligent monitoring technology based on computer vision.By real-time collecting,precessing and analyzing the video flow in the elevator and using background substraction algorithm and human tracking algorithm,some important information including the state of the door of the elevator,the states of people can be obtained.By detecting the number of the people,the area of the people, the distances between people, the moving trajectories of the people in rules, whether the violence activities happen can can provide a safe environment for the people in t e elevator and using the violence semantic judged. The technology which is proposed elevator.
