Description

实景3D智能视觉监控系统及方法 技术领域
本发明涉及安防监控领域,尤其是一种实景3D智能视觉监控系统及方法。
背景技术
安全防范系统(简称安防系统,Security System)就是利用音视频、红外、探测、微波、控制、通信等多种科学技术、采用各种安防产品和设备,给人们提供一个安全的生活和工作环境的系统,达到事先预警、事后控制和处理的效果,保护建筑(大厦、小区、工厂)内外人身及生命财产安全。
狭义的安全防范系统就是防盗报警系统(Intruder Alarm System),分为三部分构成:前端报警探头(包括红外探测器、微波探测器、震动电缆、围栏、对射、紧急按钮、窗门磁、烟感、温感等)、传输部分(包括电源线和信号线、传输设备)和报警主机组成。广义的安全防范系统包括闭路电视监控系统(CCTV System)、门禁系统(Access Control System)和防盗报警系统(Intruder Alarm System)。传统的安全防范系统一般通过CCTV来捕捉监控区域的视频。
随着安防安保监控技术的不断进步,人们对安防安保监控系统提出了新要求,需要整个安防安保监控环境(如某栋楼的空间,可包含多个楼层和多个监控区域)都是用3D捕捉的(目的是获取整个空间的信息),且需要通过CCTV等对安防安保环境内的监控区域(如空间的某个角落)进行实时动态监控。3D扫描建模技术的出现为获取整个空间的信息提供了实现的可能,然而目前通过3D扫描建模技术得到的3D模型都是静态的,无法将3D模型和实时捕捉的视频流叠加在一起实现3D模型的动态展示(即实现安防安保监控场景的实景3D监控),也未能真正实现3D模型与实时视频流的无缝融合(若在3D模型上直接贴合上一个透明视频虽然也可以直接在3D模型中看到该视频,但由于该视频是非实时的,容易因环境的改变或角度的改变而导致无法在3D模型中观看到该视频)。

参照图1,本发明实施例提供了一种实景3D智能视觉监控系统,包括:
3D扫描装置10,用于扫描监控环境的三维数据并上传;
第一服务器11,用于根据3D扫描装置上传的三维数据生成监控环境的3D模型和对应的链接;
视频流捕捉装置12,用于捕捉监控环境的监控区域的实时视频流;
第二服务器13,用于根据监控环境的3D模型以及捕捉的实时视频流在3D模型内动态展示监控区域的3D视频流。
具体地,监控环境是指安防安保监控场景的环境,如某栋大楼、某个小区等。
监控环境的三维数据可以是二维的图像、监控环境的点云数据等,其可通过各手动或自动的扫描设备(如相机、自动扫描机器人等)来采集。
第一服务器11是计算服务器,主要用于根据扫描的三维数据计算出3D模型。第一 服务器11可以是但不限于智能手机、平板电脑、笔记本电脑、智能手表、智能电视、计算机等设备。
监控环境的3D模型可展示在PC电脑屏、平板电脑(如IPAD)屏、智能手机屏或浏览器上。用户只需通过相应的链接(如URL链接)进行访问即可,省去了装载APP的过程,效率更高且更加方便。
优选地,监控环境的3D模型是虚拟的模型,可供用户进行360度无死角的浏览或观看,而且可以提供沉浸式漫游体验服务。例如监控环境的3D模型为某栋楼的3D模型,用户只需通过在浏览器等中输入该3D模型对应的链接即可访问该3D模型,从而在该3D模型中进行前进、后退、向上(如由该栋楼的第1层移动到第3层等)、向下等漫游体验操作。
视频流捕捉装置12可以是一个或多个。监控区域可根据安防安保监控的实际需要而预先设定。例如,根据安防安保监控的要求,某栋楼的安防监控区域共32个,可分别在这32个区域(如楼道、拐角处等)分别设置视频流捕捉装置来进行实时监控。
第二服务器13是展示服务器,用于展示监控环境的3D模型和在3D模型内展示监控区域的3D视频流。由于安防安保场景的监控区域是可以预先设定,所以生成监控环境的3D模型后,只需通过在该3D模型中找出监控区域并将视频流捕捉装置采集的实时视频流视叠加在该区域进行持续播放,即可在3D模型内动态展示监控区域的3D视频流,克服了传统3D扫描建模技术得到的3D模型都是静态的缺陷,真正实现了安防安保监控场景的实景3D监控。用户通过3D模型对应的链接即可访问监控环境的3D模型以及在3D模型内动态播放或展示的3D视频流。此外,与在3D模型上直接贴合上一个透明视频的简单贴合方案不同的是,由于集成到3D模型中的视频流是实时视频流,本发明可真正实现3D模型与实时视频流的无缝融合,不论环境如何改变和角度如何改变都能在3D模型中观看到该实时视频流(即实时视频流是直接融合到3D模型中的,而不是简单的贴合),不受环境(如场景)的改变和角度的改变的影响。
由上述内容可见,本实施例的第一服务器能通过3D扫描建模得到安防安保监控环境的3D模型,方便了用户通过对应的链接对安防安保监控环境的整个空间进行沉浸式漫游;第二服务器根据监控环境的3D模型以及捕捉的实时视频流在3D模型内动态展示监控区域的3D视频流,通过将监控区域捕捉的实时视频流集成到安防安保监控环境的3D模型内实现了安防安保监控场景的实景3D监控,满足了安防安保监控的高要求;同时也真正实现3D模型与实时视频流的无缝融合,不受环境(如场景)的改变和角度 的改变的影响,在环境改变或角度改变后仍能在3D模型中观看到该实时视频流。

室外扫描仪102,可以是手持扫描设备(如带支撑架的相机)或其他自动扫描设备(如自动扫描机器人)。
室内扫描仪101和室外扫描仪102内均集成有GPU芯片,能在本地对采集的二维图片等数据进行初步的处理(如将二维图片按深度信息进行初步拼接等),减轻了第一服务器的处理负担。
参照图1,进一步作为优选的实施方式,所述第一服务器11包括:

发送单元116,用于将监控环境的3D模型以及对应的链接发送给第二服务器。
具体地,用户可以通过在智能处理单元113上输入一个或多个个人详细信息(如姓名、年龄、位置、性别等)来进行注册。用户可以是拥有有效登录凭证的任何用户,而有效登录凭证可通过支付相应权限的费用来获得。
智能处理单元113集成了AI算法,能自动对扫描的三维数据进行模型修复、裁剪、减面、减模、压缩、处理材质、处理贴图、处理灯光和压缩渲染等处理,智能化程度高。
智能处理单元113可以是设置在计算设备上的应用程序。优选地,计算设备可以是但不限于智能手机、平板电脑、笔记本电脑、智能手表、智能电视、计算机等设备。

具体地,叠加单元133先在该3D模型中找出(可通过特征匹配等方式查找)监控区域,并将视频流捕捉装置采集相应的实时视频流视叠加在该3D模型的监控区域上。这样,就能在3D模型内动态展示监控区域的3D视频流,克服了传统3D扫描建模技术得到的3D模型都是静态的缺陷,真正实现了安防安保监控场景的实景3D监控;同时也真正实现3D模型与实时视频流的无缝融合,不受环境(如场景)的改变和角度的改变的影响,在环境改变或角度改变后仍能在3D模型中观看到该实时视频流。
