具体实施方式
为了使本申请实施例中的技术方案及优点更加清楚明白,以下结合附图对本申请的示例性实施例进行进一步详细的说明,显然,所描述的实施例仅是本申请的一部分实施例,而不是所有实施例的穷举。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。
实施例一
图1为本申请实施例的一种轨道列车的监控系统的结构示意图;图2为图1所示的监控系统与安装于轨道列车的示意图。
如图1和图2所示,本申请实施例的一种轨道列车的监控系统,包括:
获取装置100,用于获取所述轨道列车内的监控数据,所述监控数据包括 视频;
监控服务器200,与所述获取装置通过连接以接收及存储所述监控数据,并将所述监控数据传输至分析主机;
多个分析主机300,分别设置在所述轨道列车的车厢内,用于从所述监控数据中识别预设目标并分析,在所述预设目标的行为满足预设的预警条件时,向预警装置发送预警信息;
预警装置400,与所述监控服务器连接,用于在接收到所述监控服务器转发的所述预警信息后进行预警。
本申请实施例的轨道列车的监控系统,通过获取装置获取轨道列车内的监控数据,监控数据传输至各个分析主机,轨道列车的车厢内设置有分析主机,这样,各个分析主机各自对大量的监控数据进行分析,能够加快分析的速度;在分析主机从所述监控数据中识别预设目标并分析,在所述预设目标的行为满足预设的预警条件时,向预警装置发送预警信息,预警装置进行预警。本申请实施例的轨道列车的监控系统,对监控数据进行存储,便于以后的调用和查看,也对监控数据进行了分析,在满足预设的预警条件时,进行预警,实现了自动分析及预警,为及时发现特殊情况,尽早进行干预措施提供了依据。
实施中,轨道列车中多是采用以太网连接的。本申请实施例的轨道列车的监控系统,获取装置和监控服务器之间是通过以太网连接的,一方面有效的利用了轨道列车的以太网,另一方面,监控数据的量较大,也适合通过以太网进行数据传输。监控服务器和分析主机之间是通过以太网连接的。
分析主机对视频的分析采用时间差分的原理和背景图像差分的混合算法,用相邻帧图象相减来提取前景目标移动的信息。视频分析的过程(背景减除方法):首先系统进行背景学习,学习时间根据背景热闹程度有所不同,期间系统自动建立背景模型。之后系统进入“分析“状态,如果前景出现移动物体,并在设置的范围区域内且预设目标大小满足设置,系统将会把该预设目标进行 提取并跟踪,并根据预先的算法(入侵、遗留、斗殴等)触发预警。(期间如果背景出现获取装置抖动等,监控系统将启动预处理功能,来过滤掉这些动态背景)。在触发预警之前,监控系统具有预设目标识别的功能,即将提取的预设目标与已经建立的模型进行比对,并选择最佳的匹配。
下面对监控系统如何实现危险行为的预警进行说明。
图3为图1所示监控系统的分析主机进行是否存在危险行为的分析的流程图。实施中,预设的预警条件包括达到或超过动作幅度阀值;
如图3所示,所述分析主机具体用于进行是否存在危险行为的分析,包括步骤S300:从所述轨道列车客室区域的视频中预设的危险行为监测范围识别出所述预设目标并分析,在危险行为监测范围内所述预设目标的行为动作幅度是否达到或超过动作幅度阀值:
步骤S310:达到或超过动作幅度阀值时,向所述预警装置发送危险行为的预警信息;
步骤S320:在危险行为监测范围内所述预设目标的行为动作幅度未达到也未超过动作幅度阀值时,不发送危险行为的预警信息;
所述预警装置具体用于根据所述危险行为的预警信息,进行危险行为的预警。
针对所述轨道列车客室区域的视频中预设的危险行为监测范围,进行否存在危险行为的分析,分析的依据是达到或超过动作幅度阀值。在预设的危险行为监测范围内,作为预设目标的人的行为动作幅度达到或超过动作幅度阀值时,分析主机判断为存在危险行为,进行预警;在作为预设目标的人的行为动作幅度未达到也未超过动作幅度阀值时,分析主机判断不存在危险行为。危险行为可以根据情况进行设定,通过设定实现将斗殴等需要轨道列车的工作人员进行人工干预的各种危险行为包含在内,从而实现对危险行为的预警。
根据轨道列车客室区域中乘客所需进行的动作,对预设的危险行为监测范 围进行设置。如预设的危险行为监测范围不应该包括乘客需要进行取放行李等大幅度动作的位置,否则容易导致误判。具体的,通过设定任意多边形的范围设置为危险行为监测范围,对每一个危险行为监测范围,设定“音频检测模式”、“视频检测模式”和“音视频检测模式”,三种行为检测的一种。对于客室内危险行为监测范围的危险行为分析,CIF分辨下最小检测大小:64×32像素;最小响应时间小于2秒,检测成功率大于80%。
仅对预设的危险行为监测范围内进行是否存在危险行为的分析,是有针对性的进行是否存在危险行为的分析,降低了误判的可能性,增加了危险行为的预警的准确率,同时,也降低了分析主机进行分析的数据量。
监控服务器通过组播的方式把轨道列车客室区域内的获取装置的实时视频发送给分析主机,由分析主机对视频进行分析处理,一旦有人有危险行为情况的发生,则产生相应预警。
分析主机进行是否存在危险行为的分析是通过获取视频的图像的一系列特有的静态和动态的特性,实现对特定事件的描述和判别实现的。为了实现危险行为的分析,用到光流、聚类分析、图像特征描述、分类器等其他计算机视觉和模式识别技术。
下面对监控系统如何实现保护区域被侵入的预警进行说明。
图4为图1所示监控系统的分析主机进行保护区域是否被侵入的分析的流程图。实施中,预设的预警条件还包括保护区域内有预设目标;
如图4所示,所述分析主机具体用于进行保护区域是否被侵入的分析,包括步骤S400:从所述保护区域的视频中预设的侵入行为监测范围识别出是否存在预设目标:
步骤S410:存在所述预设目标时,向所述预警装置发送保护区域被侵入的预警信息;
步骤S420:不存在所述预设目标,不向所述预警装置发送保护区域被侵入 的预警信息;
所述预警装置具体用于根据所述保护区域被侵入的预警信息,进行保护区域被侵入的预警。
针对轨道列车的司机室和机械师室等需要特别保护的,不允许非工作人员进入的区域,设定为保护区域,并在保护区域的视频中预设侵入行为监测范围,如可以是门口周围。针对保护区域的视频,进行保护区域内是否被侵入的分析,分析的依据是保护区域中侵入行为监测范围内是否有人:
在侵入行为监测范围内识别出所述预设目标时,向所述预警装置发送保护区域被侵入的预警信息;
在侵入行为监测范围内未识别出所述预设目标时,不发送保护区域被侵入的预警信息;
所述预警装置具体用于根据所述保护区域被侵入的预警信息,进行保护区域被侵入的预警。
通过部署在车厢的获取装置可以针对重点区域(如司机室、机械师室等)进行布防,通过设置监测区域、监测面积和预警时间,以及预警输出方式,可实现对于轨道列车重点区域的安全防范和保护。
保护区域是否被侵入的预警分析,采用依赖轨迹的行为分析技术。基本方法是利用连续输入的图像序列,获取一个背景图像作为参考,后续进入的图像和背景图像进行比对,获取差异的像素点,然后对这些像素点进行连通性标记,这些标记的区域即初始的目标,然后对这些目标进行跟踪,形成连续的跟踪轨迹,然后对上述前景以及跟踪轨迹进行分析;与预先设置的规则信息比较,输出预警信息。
侵入行为监测范围可以设定任意多边形状的侵入行为监测范围;
(1)可以在同一场景中设置多个相互独立的侵入行为监测范围;
(2)对每一个侵入行为监测范围,可以设定穿越侵入行为监测范围的边界和在侵入行为监测范围两种行为检测的一或两种;
(3)在侵入行为监测范围内的监测,可以设定预设目标个数、最短报警时间,重复报警间隔时间等等;
(4)对穿越侵入行为监测范围的边界的预设目标,可以设置穿越的方向为进入、离开或是双向,保护区域是否被侵入监测在CIF分辨率下,最小检测目标大小:10×10像素,响应时间小于1秒,监测成功率大于90%。
下面对监控系统如何实现人员拥挤的预警进行说明。
图5为图1所示监控系统的分析主机进行人员是否拥挤的分析的流程图。实施中,预设的预警条件还包括达到或超过人员数量阀值;
如图5所示,所述分析主机具体用于进行人员是否拥挤的分析,包括步骤S500:从指定区域的视频中预设的拥挤监测范围识别出的预设目标的数量是否达到或超过人员数量阀值:
步骤S510:达到或超过人员数量阀值时,向所述预警装置发送人员拥挤的预警信息;
步骤S520:未达到也未超过人员数量阀值时,不发送人员拥挤的预警信息;
所述预警装置具体用于根据所述人员拥挤的预警信息,进行人员拥挤的预警。
针对轨道列车易于发生拥挤的位置设置获取装置,即该易于发生拥挤的位置就是指定区域,如轨道列车的入口到客室入口之间的过道中;在指定区域的视频中预设的拥挤监测范围,在人脸通常所在的高度范围内,排除过道的高处人脸达到不了的位置。在指定区域的视频中预设的拥挤监测范围内,识别出的预设目标的数量达到或超过人员数量阀值时,向所述预警装置发送人员拥挤的预警信息,从而实现对拥挤进行预警。
下面对监控系统如何实现声音异常预警进行说明。
实施中,所述监控数据还包括音频;预设的预警条件还包括达到或超过声 音预警阀值;
所述分析主机还用于进行声音是否异常的分析,包括:在所述音频的声音大小是否达到或超过声音预警阀值:
达到或超过声音预警阀值时,向所述预警装置发送声音异常的预警信息;
未达到也未超过声音预警阀值,不向所述预警装置发送声音异常的预警信息;
所述预警装置还用于根据所述声音异常的预警信息,进行声音异常预警。
轨道列车的车厢两侧的获取装置是具有拾音器的摄像机,可以对音频进行实时采集,由分析主机对音频进行分析处理。如果声音强度超过声音预警阀值,则产生声音异常预警。可以设定音频的声音的强度;可以设定声音报警的最短持续时间,对于声音异常的最小响应时间为1秒,检测成功率大于90%。
下面对监控系统如何实现重点布控人员的预警进行说明。
实施中,监控系统还包括人脸数据库;
所述分析主机还用于进行是否发现重点布控人员的分析,包括:从所述视频中抓取人脸图像,并将抓取的人脸图像与所述人脸数据库中的人脸进行对比识别,在抓取的人脸图像与所述人脸数据库中的人脸匹配时,向所述预警装置发送发现重点布控人员的预警信息;
所述预警装置还用于根据所述发现重点布控人员的预警信息,进行发现重点布控人员的预警。
这样,就实现了重点布控人员的预警。
重点布控人员的预警需要对乘车人员信息进行采集,通过分析主机对比,实现对重点布控人员的检索和预警。具体实现是由获取装置实现视频的抓拍,由分析主机实现数据库的特征导入和检索比对查询。
分析主机主要划分为图像抓取模块、图像比对模块、人脸数据库管理模块和人脸特征检索模块:
(1)图像抓取模块:通过轨道列车内的获取装置,抓取高铁车厢内的实时图像,并每隔若干帧就将抓取到的视频图像中的人脸图像检测出来,并传到图像比对模块进行比对;
(2)图像比对模块:提取图像抓取模块中的人脸特征;
(3)人脸数据库管理模块:管理已经记录在系统中的人脸的特征数据;
(4)人脸特征检索模块:检索提取出的人脸特征是否存在于人脸数据库中并且判断是否是重点布控人员的人脸。
重点布控人员的预警的核心是人脸识别,人脸识别算法包括三个部分:人脸检测,人脸关键检测,人脸识别。其中人脸检测是找到一张图片中包含的所有人脸,人脸关键点检测是在检测到人脸图像上检测出人脸的关键点坐标,进而估计出人脸的姿态,人脸识别是把人脸变成特定维数的向量,根据向量的相似程度来判断是否为同一个人的人脸图像。
实施中,所述分析主机,根据所述获取装置的设置位置,对各个所述获取装置获取的监控数据进行至少一种分析,包括是否存在危险行为的分析,保护区域是否被侵入的分析,人员是否拥挤的分析,声音是否异常的分析,是否发现重点布控人员的分析。
这样,根据获取装置的位置,对获取装置获取的监控数据分别进行了分析,充分利用了监控数据。
具体的,所述保护区域包括轨道列车的司机室和/或机械师室。
具体的,所述获取装置包括全景摄像机和具有拾音功能的半球形摄像机;
如图2所示,所述全景摄像机120设置在所述轨道列车的通过台处;
