如图1所示,本发明实施例提供了一种智慧城市系统,包括:
第一数据获取模块,用于通过扫描的方式获取第一数据,所述第一数据包括城市的三维数据;
第二数据获取模块,用于获取第二数据,所述第二数据包括直播视频流和现场采集的视频流;
第三数据获取模块,用于通过传感器获取第三数据,所述第三数据包括压力、温度、湿度、风向、PM2.5和图像数据;
服务器,用于根据第一数据、第二数据和第三数据进行智能处理,所述智能处理包括根据第一数据生成城市的三维模型和对应的链接,将第二数据叠加到城市的三维模型中实现城市三维实景,对城市的三维模型进行点云分割与智能识别,以及分析第二数据和第三数据;
展示模块,用于在城市的三维模型中展示第二数据、智能识别的结果和分析的结果。
具体地,第一数据获取模块,用于对城市场景内的对象进行扫描,并将扫描的数据上传给服务器。对象可以是对称物体,具有不平坦表面的不对称物体,还可以是环境或人物。第一数据获取模块可以是航拍扫描设备、室内扫描设备或室外扫描设备。航拍扫描设备,可以是航拍飞机等航拍设备,用于扫描城市区域范围的三维数据。室内扫描设备,用于扫描室内环境(如城市某栋建筑某层楼的内部)的三维数据。室内扫描设备,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)。室外扫描设备,用于扫描室外环境(如城市的某条桥梁等)的三维数据。室外扫描设备,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)。三维数据包括二维图片和深度信息等数据。优选地,第一数据获取模块可集成有GPU芯片,能在本地对采集的二维图片和深度信息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),减轻了服务器的处理负担。
第二数据获取模块,用于获取城市内某个区域(如某个路段、某栋大楼)现场的实时视频流数据。该实时视频流数据可以是CCTV(闭路电视)采集的现场实时视频流(如反映人的实时动作的视频流),也可以是在该区域现场播放的视频流(如电视直播、网络视频、现场培训视频等)。第二数据获取模块可以采用CCTV、摄像头等设备来实现。
第三数据获取模块,用于通过分布于城市各处的温度、压力、湿度、风向、PM2.5、图像传感器来采集城市的各种信息,以便于进一步的分析和处理。第三数据获取模块可以采用各种传感器来实现,其将采集的各种信息上传给服务器。
服务器,用于根据第一数据、第二数据和第三数据进行智能处理。其中,智能处理具体包括:根据第一数据生成城市的三维模型和对应的链接,将第二数据叠加到城市的三维模型中实现城市三维实景,对城市的三维模型进行点云分割与智能识别,以及分析第二数据和第三数据。
具体地,服务器在根据第一数据生成城市的三维模型时,可通过模型修复、剪辑、裁剪、减面、减模、压缩、处理材质、处理贴图和处理灯等操作对第一数据进行处理,从而重建出城市的三维模型。重建出城市的三维模型后,服务器还可生成三维模型的链接(如URL链接等),这样任何支持浏览器的计算设备(包括智能手机、平板电脑、笔记本电脑、智能手表、 智能电视、计算机等)都可以通过该链接访问该三维模型。服务器可以是能通过有线或无线的方式与扫描设备通讯的后台服务器、云端服务器等。城市的三维模型是由多个点云(点的集合)组成的,故服务器也可以在生成城市的三维模型后提供对应的点云数据,以便于后续的分割与智能识别。
而服务器在将第二数据叠加到城市的三维模型中实现城市三维实景时,可先从模型中找到要叠加视频流的区域(该区域可预先设定或其上带有可识别的标签),然后将实时视频流叠加到该区域持续播放即可。传统3D扫描建模技术得到的3D模型都是静态的,即使能展示视频数据,其也只能以一帧一帧图片的方式进行展示(仍然展示的是静态的非实时视频数据),无法真正展示动态的视频流。由于视频流是实时的,本发明实施例通过将实时视频流叠加到城市三维模型的相应区域中,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。
服务器对城市的三维模型进行点云分割与智能识别时,可再结合人工智能的方法进行识别,从而得到各个对象的名称。同时由于分割时已对点云进行了划分,结合人工智能的识别结果服务器就可以自动统计出同一名称对象的数量,省去了人工计算数量的过程,极大地提升了效率和方便了用户。统计出同一名称对象的数量,是为了方便用户观看,并可以进行进一步的应用或操作,例如:利用当前城市内酒店这一对象的数量统计结果结合GPS位置定位的信息,某个人就可以很方便地知道距离其当前位置5分钟的步行路程范围内有多少个酒店,有多少个餐饮店等等信息,以便于作出相应的选择。
服务器分析第二数据和第三数据时,可根据第二数据的实时视频流分析视频流所在区域(如安防监控区域等)的状态是否异常(如监控区域是否发生火警或紧急事件等),还可以根据第三数据分析城市的各项指标(如温度、压力、湿度、PM2.5浓度等)是否正常,以便于及时做出相应的应对或响应措施(如火警报警处理、应急事件处置、PM2.5浓度异常提醒等)。
展示模块,用于展示城市的三维模型、第二数据、智能识别的结果(如各种类型对象的名称和对应的数量等)和和分析的结果。展示模块可以采用AR显示设备、VR显示设备、移动终端、平板电脑端、PC电脑端、空气屏、LED显示屏、LCD显示屏、OLED显示屏和点阵显示屏等中的任一种来实现。
由上述的内容可知,本实施例根据扫描的第一数据生成城市的三维模型后,通过在城市的三维模型中叠加第二数据的视频流并实时展示实现了城市实景的展示,让观看者不仅能看到城市的三维模型,还可以看到动态的视频流,给了观看者沉浸式(即身临其境)的体验; 通过对城市的三维模型进行点云分割与智能识别,实现了对城市模型内的各个对象的识别并能统计出对应的数量,智能化程度高且更加方便。
进一步作为优选的实施方式,还包括通讯模块,所述通讯模块用于与第三方系统通讯连接,所述第三方系统包括政务服务系统、公共信息与卫生服务系统、医院系统、报警系统和交通系统。
具体地,本实施例的通讯模块可为有线通讯模块或无线通讯模块,用于通过通讯与政务服务系统、公共信息与卫生服务系统、医院系统、报警系统和交通系统等城市的第三方系统对接,以便于为城市居民或企业提供更好的配套或一站式服务,提升系统的便利性和用户体验。
进一步作为优选的实施方式,所述服务器具体包括:
三维重建单元,用于根据第一数据进行三维重建,得到城市的三维模型、对应的链接以及对应的点云数据;
叠加单元,用于将第二数据叠加到城市的三维模型中;

具体地,室内对象包括椅子、桌子、电脑、天花板、地板、墙、玻璃镜面和窗口等。
室外对象包括线缆、桌子、树、道路、建筑(餐饮店、便利店、办公楼等)、灯柱、车辆、视频采集装置(CCTV电视等)、绿化带(如草坪等)等。
进一步作为优选的实施方式,所述点云分割与智能识别单元具体包括:
点云分割单元,用于从城市的三维模型获取点云数据,进而根据点云数据间的关联分割出城市内各个对象的点云;
智能识别单元,用于采用人工智能的方法识别城市内各个对象的点云的名称;
自动统计单元,用于根据识别的名称自动统计城市内各个对象的数量。
具体地,城市内对象可包含多个物体、人物等对象。相应地,对扫描点云数据进行分割,得到场景内第一对象的点云也包含了多个点云,这些分割出的点云的具体名称经人工智能的方法识别后即可得出。这样将分割出的每个点云与名称对应起来,即可自动地统计出各个名称对象的具体数量,十分方便。
由上述的内容可知,本实施例点云分割完成后通过人工智能的方法等方法智能识别出城 市内对象的名称及对应的数量,以便于通过人工智能自动统计出城市内各个物体等对象的数量,智能化程度高。

具体地,本实施例可以通过体感、手势、眼球、触摸、语音和脑波中的任一种方式来提供展示控制指令,以便于对城市的三维实景进行展示控制,提升了互动效果和灵活性。放大和缩小指令主要用于控制城市三维实景内三维模型的放大与缩小;切换指令用于控制控制城市三维实景内的场景切换(如由某条马路切换到某栋建筑)、视角的切换等等;旋转指令要用于对城市三维实景内三维模型进行旋转;语音解说指令,主要用于通过多国语言(如中文、英文、法文等)为用户介绍城市内对象的三维模型等的详细信息(如介绍城市内某栋建筑的历史、当前进驻的公司名及相应的信息等);筛选指令主要用于提供筛选条件来为用户进行针对性的展示,例如,用户想知道某栋建筑5分钟或一公里范围内的所有酒店,那么筛选条件就可以包括:参照物:该栋建筑;时间或距离:5分钟或一公里范围内,类型:酒店。
