Description

三维空间视图显示方法、装置及存储介质 技术领域
本公开涉及计算机技术领域，尤其涉及一种三维空间视图显示方法、装置及存储介质。
背景技术
随着房地产行业的深入发展，家居装饰行业也得到了极大的发展，对家居的装饰需求也越来越大。在传统的装修流程中，需要专业的且经验丰富的设计师提出改造设计，普通住户往往无法胜任，家具布局的效果严重依赖于专业设计师。用户要想看到基于自己户型的房屋装修效果，需要经过专业设计师量房、与用户沟通风格喜好、设计等流程，往往需要大量的时间设计图纸，占用了大量的设计师资源，设计流程时间长、事情繁琐且价格昂贵，不具备普遍适用性。
与目前流行的图片看房、视频看房、全景看房等无法提供深度信息和真实感知的看房概念不同的是，“VR看房”是指利用VR技术真实还原出房源三维场景，为用户提供自由模式下的沉浸式看房体验，从而让用户足不出户即可体验到真实看房场景。例如，通过打开APP上的VR房源，触摸屏幕任意处即可获得包括房屋真实空间的尺寸、朝向、远近等深度信息。在还原房源三维场景这方面，可以先对房屋进行多点多角度的扫描拍摄，得到完整的三维点云数据、经纬度数据以及多曝光的高清彩色照片，后期通过自动建模、智能空洞填补、全自动数据提取，HDR优化等三维重建技术，将全部数据及图片纹理映射到三维模型上，得到最终用户看到的真实房屋空间。
用户所看到的VR房源，有新房、二手房，对于新房很多是毛坯房，对于二手房，有的装修多年，且设施陈旧，用户一般购买房屋后均需进行装修才能入住。单纯依据实际的VR房源看房，用户无法获知装修后的房源景象，因此，看房信息不全面，不利于用户购房决策。

还应理解，本公开对各个实施例的描述着重强调各个实施例之间的不同之处，其相同或相似之处可以相互参考，为了简洁，不再一一赘述。
同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本公开及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为说明书的一部分。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
本公开的实施例可以应用于终端设备、计算机系统、服务器等电子设备，其可与众多其它通用或者专用计算系统环境或配置一起操作。适于与终端设备、计算机系统或者服务器等电子设备一起使用的众所周知的终端设备、计算系统、环境和/或配置的例子包括但不限于：个人计算机系统、服务器计算机系统、瘦客户机、厚客户机、手持或膝上设备、基于微处理器的系统、机顶盒、可编程消费电子产品、网络个人电脑、小型计算机系统、大型计算机系统和包括上述任何系统的分布式云计算技术环境等等。

图1示出了根据本公开的实施例的示例性三维虚拟现实(VR)环境100。如图1所示，3D VR环境100可以模拟或表示住宅单元，诸如公寓或住宅楼层。注意，3D VR环境100可以包括任何室内空间或环境的VR表示。参考图1，3D VR环境100可以包括一个或多个功能间，诸如110、120、130、140、150和160。如本文所使用的，功能间是指与特定功能相关联的封闭或部分封闭的空间。在一些情况下，功能间可以对应于房间。例如，功能间110可以对应于第一卧室，并且功能间130可以对应于第二卧室。在一些情况下，功能间可以对应于房间内或与房间相邻的封闭或部分封闭的空间。例如，功能间140可以对应于壁橱。在一些情况下，功能间可以对应于通常用于特定目的的区域。例如，功能间120可以对应于厨房区域，功能间150可以对应于餐厅区域，功能间160可以对应于客厅。尽管功能间120、150和160可以共享相同的房间(例如，封闭区域)，但是由于它们的功能不同，它们可以被认为是不同的功能间。
图2示出了被配置为实施本文所公开的各种功能的示例性计算机系统200的框图。例如，计算机系统200可以被配置为用于创建或重建VR环境100的服务器。在另一示例中，计算机系统200可以被配置为用于显示或丰富VR环境100的终端设备。如图2所示，计算机系统200可以包括处理器210、通信接口220、存储器/存储设备230和显示器240。存储器/存储设备230可以被配置用于存储计算机可读指令，所述计算机可读指令在由处理器210执行时可以使处理器210执行本文所公开的各种操作。存储器230可以是任何非暂态类型的大容量存储设备，诸如易失性或非易失性、磁性、基于半导体、基于磁带、光学、可移除、不可移除或其他类型的存储设备，或有形计算机可读介质，包括但不限于ROM、闪速存储器、动态RAM和静态RAM。
处理器210可以被配置用于根据存储在存储器230中的指令来执行操作。处理器210可包括任何适当类型的通用或专用微处理器、数字信号处理器、微控制 器等。处理器210可以被配置为专用于执行本文所公开的一个或多个特定操作的单独处理器模块。可替代地，处理器210可以被配置为能够执行与本文公开的一个或多个特定操作无关的其他操作的共享处理器模块。
通信接口220可以被配置为在计算机系统200与其他设备或系统之间传输信息。例如，通信接口220可以包括综合业务数字网(ISDN)卡、电缆调制解调器、卫星调制解调器、或用于提供数据通信连接的调制解调器。作为另一示例，通信接口220可以包括局域网(LAN)卡，以提供与相容LAN的数据通信连接。作为另一示例，通信接口220可以包括高速网络适配器，诸如光纤网络适配器、10G以太网适配器等。通信接口220还可以实施无线链路。在这种实施方式中，通信接口220可以经由网络发送和接收携载表示各种类型信息的数字数据流的电信号、电磁信号或光信号。网络通常可以包括蜂窝通信网络、无线局域网(WLAN)、广域网(WAN)等。
通信接口220还可以包括各种I/O设备，诸如键盘、鼠标、触摸板、触摸屏、麦克风、相机、生物传感器等。用户可以通过通信接口220将数据输入到终端设备。

图3是根据本公开的一种三维空间视图显示的示例方法的流程图。所述三维空间视图至少包括第一三维空间视图和第二三维空间视图，所述方法包括：在步骤301，在第一用户界面上呈现所述第一三维空间视图；在步骤302，在第二用户界面上呈现所述第二三维空间视图；在步骤303，根据用户输入，改变所述第一三维空间视图；在步骤304，根据所述第一三维空间视图的改变，改变所述第二三维空间视图。
图4是根据本公开的一种三维空间视图显示的另一示例方法的流程图。所述 三维空间视图至少包括第一三维空间视图和第二三维空间视图。
如图4所述，在步骤401，在第一用户界面上呈现第一三维空间视图。
在步骤402，在第二用户界面呈现第二三维空间视图。所呈现的第二三维空间视图和第一三维空间视图可以具有相同的视场。
第一用户界面和第二用户界面可以是子页面，例如是浏览器(如，IE浏览器，Chrome浏览器等)的第一子页面和第二子页面。
三维空间视图，也称全景视图。一种生成房屋的三维空间视图(即房屋全景)的方法是用相机拍摄房屋里多个位置的周围环境的相片，将这些相片进行合成，从而得到这些位置的房屋全景。例如，可以在房屋里的某个位置在水平方向上围绕垂直轴转动相机并在垂直方向上围绕水平轴转动相机，将由此拍摄的一系列相片进行合成，从而得到该位置的房屋全景。另一种方法是采用计算机模拟生成房屋的三维空间视图。
视场通常包括视场方向和视场的角度范围(即视角)，视场方向也称作视角的视线方向。因此，视场的一个特征是其方向，例如可以由从已知方向(例如，北向)测得的方位角和从已知方向(例如，水平面)测得的倾角来定义。视场的另一个特征在于视角，视角描述给定场景的角度范围。
在步骤403，在所述第一用户界面接收用户输入，以根据所述用户输入生成第一三维空间视图的视图改变指令。
用户可在显示区域(即用户界面)中操纵三维空间视图。用户可以通过左右、上下拖动操作以改变视场的方向和角度范围。用户还可以通过缩放操作以改变视场的角度范围。在一些实现方式中，用户可以通过点击叠加在三维空间视图上的导航控件来从一个位置的三维空间视图导航到另一位置的三维空间视图。
在一些实现方式中，可以为第一房屋在m个位置生成全景图(这m个位置构成第一位置集合)，为第二房屋在n个位置生成全景图(这n个位置构成第二位置集合)。n和m均为整数，这二者可以相等也可以不等。可以分别对这m和n个位置编号(例如从1开始连续编号)，也即，用编号来表示位置，第一个编号(例如编号1)的位置表示初始位置。具有相同编号的位置认为是对应位置，由此建立第一位置集合和第二位置集合之间的映射关系。第一房屋和第二房屋可以是相同的 房屋，即可以为同一房屋生成不同的全景图。例如，可以为同一房屋生成装修前后的不同三维空间视图，为装修前的房屋生成第一三维空间视图，为装修后的房屋生成第二三维空间视图。
在一些实现方式中，视图改变指令包括第一三维空间视图的视场变化信息和/或编号(或位置，也称作点位)变化信息。
在步骤404，所述第一用户界面根据视图改变指令加载用于更新第一三维空间视图的数据。
在步骤405，所述第一用户界面将视图改变指令发送给所述第二用户界面。
在步骤406，所述第二用户界面根据视图改变指令加载用于更新第二三维空间视图的数据。
在步骤407，所述第一用户界面和所述第二用户界面分别根据加载的用于更新第一三维空间视图的数据和加载的用于更新第二三维空间视图的数据更新所述第一三维空间视图和所述第二三维空间视图。
在一些实现方式中，更新后，第一三维空间视图和第二三维空间视图具有相同的视场。在一些实现方式中，更新后，第一三维空间视图和第二三维空间视图对应于相同的位置(或编号)。
在一些实现方式中，所述第一用户界面和所述第二用户界面分别根据加载的用于第一三维空间视图的数据和加载的用于第二三维空间视图的数据同时更新所述第一三维空间视图和所述第二三维空间视图。也就是说，所述第一用户界面加载用于更新第一三维空间视图的数据，所述第二用户界面加载用于更新第二三维空间视图的数据，之后，会在两个用户界面进行同步，以同时更新所述第一三维空间视图和所述第二三维空间视图。所述同步例如包括：所述第一用户界面通知所述第二用户界面其已完成数据加载，所述第二用户界面通知所述第一用户界面其已完成数据加载，由此实现所述第一用户界面和所述第二用户界面同时更新所述第一三维空间视图和所述第二三维空间视图。
上述三维空间视图显示方法的一个应用场景是装修前后房屋三维模型同屏显示。在装修前后房屋三维模型同屏显示的情形下，根据用户输入，改变所述第一三维空间视图包括：用户终端获取用户在第一三维空间视图(也称作当前虚拟三 维空间)中漫游和/或扫视的视角变化信息。所述视角变化信息例如可以包括点位(或位置)变化信息和/或视线方向变化信息。其中，根据所述第一三维空间视图的改变，改变所述第二三维空间视图包括：若所述第一三维空间视图对应于第一房屋三维模型，第二三维空间视图对应于第二房屋三维模型，则根据所述视角变化信息调整第二房屋三维模型的显示视角，使得所述第一房屋三维模型和所述第二房屋三维模型同屏同视角显示；若所述当第一三维空间视图对应于所述第二房屋三维模型，第二三维空间视图对应于第一房屋三维模型，则根据所述视角变化信息调整所述第一房屋三维模型的显示视角，使得所述第一房屋三维模型和所述第二房屋三维模型同屏同视角显示。下面对装修前后房屋三维模型同屏显示进行详细描述。
图5是本公开实施例提供的装修前后房屋三维模型同屏显示的方法流程图。如图5所示，所述方法包括：
步骤501、用户终端获取用户在当前虚拟三维空间中漫游和/或扫视的视角变化信息；所述视角变化信息包括点位变化信息和/或视线方向变化信息；
步骤502、若所述当前虚拟三维空间对应于第一房屋三维模型，则根据所述视角变化信息调整第二房屋三维模型的显示视角，使得所述第一房屋三维模型和所述第二房屋三维模型同屏同视角显示；
步骤503、若所述当前虚拟三维空间对应于所述第二房屋三维模型，则根据所述视角变化信息调整所述第一房屋三维模型的显示视角，使得所述第一房屋三维模型和所述第二房屋三维模型同屏同视角显示；
其中，所述第一房屋模型和所述第二房屋模型在所述用户的视角发生变化前已处于同屏同视角显示状态；所述第一房屋三维模型是指当前房屋的三维模型(即未加载推荐装修效果的房屋三维模型)，所述第二房屋三维模型是指加载了推荐装修效果后的已装修房屋三维模型。
所述当前房屋的三维模型是指实际房源的房屋三维模型(装修前的房屋三维模型)。所述已装修房屋三维模型是以相应的实际房源为基础，进行模拟装修后的房屋三维模型(装修后的房屋三维模型)。
所述推荐装修效果是指根据用户的房屋户型、朝向、采光、楼层等房屋属性， 在用户的原先房屋的三维模型中抹去了所有房屋已有装修家具家电后，在房屋的三维模型中添加了各种家具家电模型后的装修效果。
用户在房屋三维模型的虚拟三维空间(VR空间)中可以进行游走和/或扫视，以实现身临其境的看房效果。游走，比如从一个点位移动到另一个点位；扫视，比如看向房间的某部分区域。在用户漫游和/或扫视的视角发生变化前，装修前的房屋三维模型和装修后的房屋三维模型已同屏同视角显示于用户终端(前端)的显示界面。用户可以在装修前的房屋三维模型的虚拟三维空间中游走和/或扫视，也可以在装修后的房屋三维模型的虚拟三维空间中游走和/或扫视。
当用户在一个点位进行扫视时，可以转换视线方向(比如通过滑动屏幕)，实现对于房间不同区域的扫视；当用户从一个点位移动到另一个点位时，必然会使得视角发生变化，并且用户移动到新点位后还可以进一步转换视线方向，使得视角发生新的变化。
因此，用户在同一个点位进行视角变化时，可以通过获取视线方向变化信息实现；用户从一个点位移动到另一个点位时，可以通过获取点位变化信息来获取视角变化信息；用户从一个点位移动到另一个点位，并且进一步转换视线方向时，可以通过点位变化信息和视角变化信息获取视角变化信息。

若所述当前虚拟三维空间对应于装修前的房屋三维模型，则用户终端根据用户在装修前的房屋三维模型的虚拟三维空间中漫游和/或扫视的视角变化信息调整装修后的房屋三维模型的显示视角，使得装修后的房屋三维模型的视角变化与装修前的房屋三维模型的视角变化一致，实现所述装修前的房屋三维模型和所述装修后的房屋三维模型同屏同视角显示。
若所述当前虚拟三维空间对应于装修后的房屋三维模型，则用户终端根据用户在装修后的房屋三维模型的虚拟三维空间中漫游和/或扫视的视角变化信息调整装修前的房屋三维模型的显示视角，使得装修前的房屋三维模型的视角变化与 装修后的房屋三维模型的视角变化一致，实现所述装修前的房屋三维模型和所述装修后的房屋三维模型同屏同视角显示。

如前所述，在实现装修前的房屋三维模型和装修后的房屋三维模型同屏同视角联动之前，装修前的房屋三维模型和装修后的房屋三维模型处于同屏同视角显示状态。那么，在上述实施例的基础上，本公开实施例将给出装修前的房屋三维模型和装修后的房屋三维模型最初实现同屏同视角显示的实施例。
在用户终端的APP中，用户可以通过点击某个房屋三维模型进入某个房屋三维模型的虚拟空间进行扫视游走，从而实现相应房屋三维模型的显示。比如，用户可以点击装修前的房屋三维模型，实现装修前的房屋三维模型的显示；也可以点击装修后的房屋三维模型，实现装修后的房屋三维模型的显示。装修后的房屋三维模型和装修后的房屋三维模型均存储于后台服务器，用户终端可以向后台服务器发送请求指令显示相应的三维模型。
若用户终端获取到装修前的房屋三维模型的显示请求信息(比如获取到用户对装修前的房屋三维模型的点击信息)，则显示所述装修前的房屋三维模型。为了实现装修前的房屋三维模型和装修后的房屋三维模型同屏同视角显示，用户终端 在显示所述装修前的房屋三维模型后，获取装修前的房屋三维模型的视角信息(显示视角信息)，并从后台服务器获取所述装修后的房屋三维模型，并且根据所述装修前的房屋三维模型的视角信息显示所述装修后的房屋三维模型，使得装修前的房屋三维模型和装修后的房屋三维模型同屏同视角显示。

图6是本公开另一实施例提供的装修前后房屋三维模型同屏显示的方法流程图。如图6所示，本公开实施例提供的装修前后房屋三维模型同屏显示的方法可以实现便利的装修前后对比，由步骤获取房屋数据601、输入对比模型602、同步坐标视线603、前端同步呈现604组成，具有实时性、同步性的特点。
首先在后台根据现有房屋的户型图等数据生成空的三维模型，再将已有的家具模型摆放到三维模型中，实现根据现有房屋三维模型生成装修后的三维模型，然后在后台输入两个已有模型，尤其对于毛坯房、简装房这些装修前后对比较为明显的房屋，两个对比性明显的三维空间可为用户提供更多的可视化信息。
用户在三维空间漫游及扫视时，前端需要对用户当前视角画面内的坐标和视线进行分析，识别其在三维模型中的点位，并触发同步两个三维模型，促使同屏呈现装修前后的两个模型。比如当用户在其中一个子页面中转动视角时，转动视角的子页面会把视角的变化上报给父页面，父页面再把视角的变化下发给全部的 子页面，实现所有子页面的状态同步，或者，转动视角的子页面把视角的变化直接发给其他子页面，实现所有子页面的状态同步。此外，用户在同屏的两个窗口中均可进行交互，根据自身需求可点击相应模型进行查看和对比。
在现有VR看房的基础上，为了实现装修前后房屋模型的同步对比，本公开实施例在前端的一个屏幕中呈现两个窗口，呈现不同内容，并同步用户在不同三维空间中的坐标和视角，实现两个三维模型的联动。
本公开实施例通过获取VR数据、房屋数据、户型数据、装修数据，以智能的方式，基于现有房屋数据预先生成装修后的三维模型并输入到后台中，在前端，用户触达的子页面状态会上传到父页面，再通过父页面下发给其他子页面(或者用户触达的子页面状态会直接发给其他子页面)，并通过视角同步、全景/模型切换和点位切换保障三维空间内信息展示的同步性。
