以监管生产层为例，监管客户端可以从工艺工法数据库获取预设产物数据和获取管理平台转发的产物数据，然后对比产物数据和预设产物数据以生成生产监管数据。这样，本示例中通过对生产层的监管，可以方便监管人员了解生产进度以及产物数据与预设产物数据是否相匹配，当相匹配时可以继续监控且不匹配时可以生成监管指令并发送给生产客户端以提醒生产层及时改正，达到在生产过程中即可实现监管的效果，避免出现产物数据与预设产物数据不相符的问题，有利于提升监管效率。并且，当建筑行业政策变化或者用户要求变化时，监管客户端可以监管预设产物数据是否同步，以及产物数据是否根据上述预设产物数据的变化同步更新，从而可以提前保证产物满足符合预设产物数据的要求，有利于提升产物的生产质量和提升监管效率。
以监管施工层为例，监管客户端可以从工艺工法数据库获取预设产物数据和获取管理平台转发的施工数据，然后对比预设产物数据和施工数据以生成施工监管数据。这样，本示例中通过对施工层的监管，可以方便监管人员了解施工进度，以及施工数据与预设设计数据是否相匹配，当相匹配时可以继续监控且不匹配时可以生成监管指令并发送给施工客户端以提醒生产层及时改正，达到在施工过程中即可实现监管的效果，避免出现施工数据与预设设计数据不相符的问题，有利于提升施工成功率。并且，当建筑行业政策变化或者用户要求变化时，监管客户端可以监管施工数据是否根据上述变化同步更新，避免出现重复施工问题，有利于提升监管效率。
需要说明的是，本实施例中监管客户端可以获取不同客户端的数据并向不同客户端发送监管指令，使监管层的数据平均分布于各个层级之间，扩大监管范围，保证建筑项目的质量。并且，本实施例提供的BIM可视化系统还可以通过监管客户端实现远程操作即达到远程实时监管的效果，可以节省人工巡视成本。
需要说明的是，本实施例中设计客户端、生产客户端、施工客户端和监管客户端可以分别部署到移动终端、个人计算机等可视化平台，管理平台作为实现数据转发和处理的平台可以部署到服务器或者服务器集群中。
在一实施例中，管理平台可以获取设计客户端上传的设计数据和生产客户端上传的产物数据，然后对比上述设计数据和产物数据以生成第一对比数据，该第一对比数据可以用于表征产物是否满足设计数据的要求。
本示例中，上述对比设计数据和产物数据是一个双向同步过程：
第一个方向，管理平台可以根据设计数据(或者根据设计数据生成的生产指令)下发给生产层或者生产客户端(图中未示出)，生产层会根据上述设计数据或者生产指令生产结构体，并得到产物数据；然后生产层可以将上述产物数据上传到管理平台；管理平台可以对比产物数据与设计数据是否相匹配或者满足设计数据的要求。对比过程可以是：管理平台将设计数据和产物数据处理为统一的格式，采用递归算法在数据库中依次比对设计数据和产物数据，直至对比完所有的产物数据为止，获得第一对比数据。
第二个方向，生产层在生产过程中会主动对比所生产的结构体或者结构体的一部分是否满足设计数据的要求，并将上述对比结果上传到管理平台。对比过程可以参见第一个方向的对比过程，其区别在于，该生产层仅需要匹配所生产的结构体的数据即可。
可理解的是，本示例中双向同步对比过程可以由管理平台或者生产层实现，相较于人工对比过程，可以极大的减少对比工作量；并且，上述对比过程和对比结果可以保证客观度和公平度，避免因人为原因带来的数据失真。另外，上述第一对比数据可以是管理平台自身需要处理的数据作为存档使用，还可以与后续监管客户端生成的施工监管数据进一步对比使用。在一示例中，该第一对比数据还可以作为生产监管数据直接使用，即监管客户端读取上述第一对比数据，以及根据上述第一对比数据生成相应的监管指令并将监管指令下发到相应的生产客户端，以达到及时提醒生产层的效果。
在一实施例中，管理平台可以获取生产客户端上传的产物数据和施工客户端上传的实体作业数据，然后对比上述产物数据和施工数据以生成第二对比数据，其中第二对比数据用于表征产物实体是否满足产物数据的要求。例如产物实体是否是之前提供的产物，所传感器所采集的产物实体的数据与产物数据是否匹配等，即通过第二对比数据可以确定产物实体是否被更换，是否按照预设安装方式安装等。
本示例中，上述对比施工数据和产物数据是一个双向同步过程：
第一个方向，管理平台可以根据产物数据(或者根据产物数据生成的施工指令)下发给施工层或者施工客户端。施工层会根据上述产物数据或者施工指令进行施工，得到实体作业数据即施工数据。然后施工层可以将上述即施工数据上传到管理平台；管理平台可以对比产物数据与施工数据是否相匹配或者满足产物数据的要求或者设计数据的要求。对比过程可以是：管理平台将施工数据和产物数据处理为统一的格式，采用递归算法在数据库中依次比对施工数据和产物数据，直至对比完所有的施工数据为止，获得第二对比数据。
第二个方向，施工层在施工过程中会主动对比所施工的结构体或者结构体的一部分是否满足产物数据的要求，并将上述对比结果上传到管理平台。对比过程可以参见第一个方向的对比过程，其区别在于，该施工层仅需要匹配所施工的结构体的数据即可。
可理解的是，本示例中双向同步对比过程可以由管理平台或者生产层实现，相较于人工对比过程，可以极大的减少对比工作量；并且，上述对比过程和对比结果可以保证客观度和公平度，避免因人为原因带来的数据失真。另外，上述第二对比数据可以是管理平台自身需要处理的数据作为存档使用，还可以与后续监管客户端生成的施工监管数据进一步对比使用。在一示例中，该第二对比数据还可以作为施工监管数据直接使用，即监管客户端读取上述第二对比数据，以及根据上述第二对比数据生成相应的监管指令并将监管指令下发到相应的施工客户端，以达到及时提醒施工层的效果。
在一实施例中，管理平台还包括云数据库。该云数据库可以与可视化平台通信，可以将设计数据和施工数据发送给可视化平台。除了上述设计数据和施工数据外，云数据库还可以被配置为存储不同时段的拼装率、抗震等级、沙盘数据和生产资料数据等等，可以根据实际场景进行设置，在此不作限定。
需要说明的是，本实施例中云数据库和工艺工法数据库两者均用于存储数据，区别在于：云数据库主要用于存储一些既有数据，这些既有数据是提供材料选型方案(如上述的预设产物数据)和满足拼装率或者绿化率等硬性指标的数据来源，可以实现既有数据的持久化留存和扩展，有利于提升复杂建筑项目的生产力，也利于后续溯源和定位问题。工艺工法数据库主要用于存储设计数据和产物数据、结构体基本模型(如BIM系统中墙，梁，板，钢筋)等模型、生产层的施工设备模型等，从而方便可视化平台从工艺工法数据库中快速读取模型并生成三维立体模型，基于该三维立体模型可以作为建筑项目实体的数据孪生模型，方便对建筑项目的生命周期进行管理。
结合云数据库和工艺工法数据库的区别，本实施例中管理平台可以被配置为从工艺 工法数据库获取设计数据，并将设计数据转发给设计客户端、施工客户端或者监管客户端，以及可视化平台可以从工艺工法数据库中读取模型并生成三维立体模型，结合GIS引擎提供的地图数据，可以将三维立体模组映射到地图数据中，可以实现用地理信息管理多处建筑项目，同时可视化的模型效果可以实时表现工程进度和相应数据指标。
继续参见图2，本公开实施例提供的一种BIM可视化系统的工作过程可以包括：
管理平台的设计客户端可以检测设计层的需求，从云数据库获取预设设计数据并反馈给设计客户端，这样设计层可以通过现有应用程序的接口与设计客户端通信以获得上述预设设计数据。然后，设计层可以基于上述预设设计数据进行设计，例如建模设计和指标设计，得到每个建筑项目对应的设计数据。设计客户端与设计层设置的接口通信，获得设计层上传的设计数据。管理平台可以将上述设计数据转发到工艺工法数据库。
管理平台的生产客户端可以检测生产层的需求，从云数据库获取预设产物数据并反馈给生产客户端，这样生产层可以通过现有应用程序的接口与生产客户端通信以获得上述预设产物数据。然后，生产层可以基于上述预设产物数据进行生产，得到每个建筑项目对应的产物数据。生产客户端与生产层设置的接口通信，获得生产层上传的产物数据。管理平台可以将上述产物数据转发到工艺工法数据库。
管理平台的施工客户端可以检测施工层的需求，从工艺工法数据库获取设计数据和产物数据中的部分数据(如设计图纸，供货单，采购单，以及物流运输等信息)并反馈给施工客户端，这样施工层可以通过现有应用程序的接口与施工客户端通信以获得上述设计数据和产物数据。然后，施工层可以基于上述设计数据和产物数据进行施工，得到每个建筑项目对应的实体作业数据即施工数据。施工客户端与施工层设置的接口通信，获得施工层上传的施工数据。管理平台可以将上述施工数据转发到工艺工法数据库。实际应用中，上述施工数据还可以参考以下方式获得：在建筑项目的固定点位部署摄像机，通过摄像机采集建筑项目的施工数据并上传到管理平台；或者，部署航拍设备，通过航拍设备采集建筑项目的施工数据并上传到管理平台。这部分数据可以存储到云数据库。管理平台可以对上述施工数据建模得到3D模型，再将3D模型发送到工艺工法数据库。
管理平台在获得设计数据和产物数据后还可以对两者进行对比以生成第一对比数据，并将上述第一对比数据存储到云数据库。该第一对比数据可以作为管理平台中监管客户端监管设计层和生产层的监管依据。
管理平台在获得产物数据和实体作业数据后还可以对两者进行对比以生成第二对比 数据，并将上述第二对比数据存储到云数据库。该第二对比数据可以作为管理平台中监管客户端监管施工层和生产层的监管依据。
可视化平台可以从工艺工法数据库读取设计数据和施工数据进行处理，生成三维立体模型，并显示三维立体模型。该三维立体模型可以包括沙盘模型，拼接的大尺寸显示屏或者坐席台式机可以显示沙盘模型以体现出建筑项目在不同场景下的效果示意，例如春夏秋冬时节下小区内风景效果。该三维立体模型可以包括数字孪生模型，通过数字孪生模型可以体现出建筑项目在设计、施工、使用等过程中的效果。另外，可视化平台还可以实现电子签字、监管分发等功能，从而提升管理效率。
管理平台可以将第一对比数据或第二对比数据发送给监管客户端，以使监管客户端根据上述第一对比数据或第二对比数据生成监管指令，并将监管指令发送给设计客户端、生产客户端或者施工客户端，从而在监管不同方按照要求作业，可以达到即工即查、即停即改和实时可见的效果。
或者，可视化平台在显示三维立体模型的过程中，可视化平台可以响应于监管层的操作生成预警信息，并将预警信息发送给监管客户端。监管客户端根据上述预警信息生成监管指令，并将监管指令发送给设计客户端、生产客户端或者施工客户端，从而在监管不同方按照要求作业。可见通过可视化平台提供预警信息，可以使数据采集、处理、可视化和监管形成一个数据闭环，达到提升监管效率的效果。
至此，本实施例通过将设计数据和施工数据生成三维立体模型并显示该三维立体模型，可以可视化各类建筑项目，达到实时监控的效果。并且，本公开中通过生成三维立体模型可以对建筑项目进行仿真，从而了解建筑项目的生命全周期，有利于对生命全周期进行管理；以及对建筑项目的施工进度等进行监管，达到建筑项目满足设计要求的效果。
继续参见图4，本公开实施例提供的一种BIM可视化系统的实现可视化过程可以包括：
可视化平台可以提供一个交互界面，通过该交互界面可以访问工艺工法数据库。在访问过程中，可视化平台可以将工艺工法数据库内的模型以列表的形式列出，以供使用者选择。
可视化平台可以响应使用者在交互操作页面的触发操作，获取触发操作对应的模型。基于上述原理，在多次操作后即可形成三维立体模型。由于工艺工法数据库中提供的模 型为理想模型，因此上述三维立体模型是一个初始模型，如黑白颜色表示的模型。然后，可视化平台对上述初始模型进行渲染，并显示在可视化平台的显示屏之上。
管理平台可以按照设计数据或施工数据等确定出里程碑结点，如建筑项目的地基完成浇筑、建筑封顶等等；然后，管理平台可以根据上述结点确定采集图像的目标位置，引导施工层在上述目标位置部署传感器，如摄像头、相机和航拍设备，并控制上述传感器采集图像数据，这些图像数据可以做施工数据的一部分上传到云数据库。
可视化平台可以通过上述交互界面继续访问管理平台的云数据库，获取里程碑结点对应的图像数据以及图像数据提供的图片或视频中的色彩资源数据，然后将上述色彩资源数据传入可视化渲染引擎，并更新初始模型，最终得携带色彩的第一目标模型，效果如图5所示。
在可视化显示过程中，可视化平台还可以在三维立体模型中增加水纹仿真效果，增加水纹仿真效果的实现过程：
本实施例中，可视化平台可以获取上述第一目标模型。实际应用中，可视化平台可以设有交互式图形程序，如OpenSceneGraph(OSG引擎)；在运行上述OSG引擎的过程中，可视化平台可以根据使用者的操作建立飞行器、游戏、虚拟现实、建筑模型等3D模型。并且，上述3D模型中的一部分区域会存在水域，如河流、湖泊、海洋、港口、喷泉等。
本实施例中，在仿真过程中，可视化平台可以显示交互界面，该交互界面内可以包括菜单栏，菜单栏内包括多种水纹格式的插槽。使用者可以结合第一目标模型的实际需求和/或用户需求等，从菜单栏选择其中一个插槽作为第一目标模型的目标区域对应的插槽。需要说明的是，第一目标模型可以包括多个目标区域，并且每个目标区域对应一个插槽。考虑到每个插槽的处理方式相同，后续实施例中以向一个目标区域贴合插槽为例描述各方案，从而方便描述和理解。
本实施例中，可视化平台可以响应于获取到检测到有获取水纹的需求，获取水纹对应的目标区域。实际应用中，第一目标模型会存在“镂空”区域，这些“镂空”区域需要插入一些位图图像以获得预期效果，本实施例中可以将上述“镂空”区域作为水纹对应的目标区域。
本实施例中，可视化平台可以设置有本地数据库，该数据库内可以存储位图图像，包括但不限于jpg，png，bitmap等格式的位图，可以是由图像解析而成的像素矩阵。或 者，位图图像的相关数据如动态链接库dll文件或者静态链接库lib文件。当可视化平台读取到第一目标模型中包含水域的节点时，可以从本地数据库读取位图图像，此时可视化平台可以确定检测到第一目标模型在仿真过程中有获取水纹的需求。可视化平台可以从本地数据库中读取位图图像，并将目标区域对应的位图图像插入其中。
需要说明的是，本实施例中在插入位置图片之前，可视化平台可以判断第一目标模型的指定参数变化是否合法，例如法线角度是否在0～180度之间，正弦值的取值范围是否在0～1或者范围扩展至位图图像边界等，上述指定参数根据具体场景选择，在此不作限定。
本实施例中，可视化平台可以设置有本地数据库，该数据库内可以存储位图图像，包括但不限于jpg，png，bitmap等格式的位图，可以是由图像解析而成的像素矩阵。或者，位图图像的相关数据如动态链接库dll文件或者静态链接库lib文件。当可视化平台读取到第一目标模型中包含水域的节点或者使用者为目标区域选择插槽时，可以从本地数据库读取位图图像，此时可视化平台可以确定检测到第一目标模型在仿真过程中有获取水纹的需求。可视化平台可以获取目标区域对应的插槽。
可视化平台可以获取位图图像中的目标点以及目标点对应的法线。上述目标点可以理解为处理位图图像的基准点。可视化平台可以获取映射点和位图图像的中心点；上述映射点为位图图像坐标系的坐标原点映射到世界坐标系中对应的起点。可视化平台可以获取上述映射点和中心点之间连线的中点，得到第一中点。当第一中点位于位图图像之内时，可视化平台可以确定第一中点作为目标点。当第一中点位于位图图像之外时，如图6所示效果，映射点a和位图图像的中心点b之间连线的中点c即第一中点c，位于位图图像的外部。此时可视化平台可以获取位图图像的预设点(如位图图像为矩形时其中一个角点)和位图图像的中心点之间连线的中点，得到第二中点；该第二中点落入位图图像之内，如图7所示效果，预设点d和位图图像的中心点b之间连线的中点e即第二中点e，位于位图图像的内部。此时可视化平台可以确定所述第二中点作为所述目标点。本步骤通过获取目标点可以获取处理位图图像的基准点，以保证水纹位于位图图像之内，提升处理效率。
本实施例中，目标点的法线是经过目标点且与位图图像的坐标系中z轴平行的直线。参见图8，底部直线表示背景平面，背景平面上方包含2个正弦波的曲线表示水域表面，正弦波表示水纹，水域表面上方的垂直于背景平面的竖线表示使用者观看水域平面的视线。以目标点位于x0处为例，此处水域表面为平面，水域表面的法线垂直于背景平面， 视线L0与x0处法线平行，此时视线可以透过水域表面垂直到背景平面。以目标点位于x处为例，此处水域表面有水纹，此时法线变成L2与背景平面不再垂直即保持一个夹角，此时视线可以透过水纹的折射作用到达x1处。基于上述原理，当水域表面包括多个水纹时通过调整视线的方向，可以使使用者的视线不均匀的分布的背景平面，达到观看到水纹的效果。基于图8示例的效果可知，无论目标点在水域表面的平面处或者水纹处其法线均与位图图像的坐标系中z轴平行。
可视化平台可以以所述目标点对应的法线为基准结合噪声数据中的预设角度，获取所述目标点周围像素的变换数据，以及根据所述目标点确定待处理像素。可理解的是，变换数据是指调整周围像素的像素值以形成水纹所需的数据，该变换数据与预设角度和方向向量相关联，该方向向量表征待处理像素与目标点之间方向，即从目标向看向待处理像素方向时所形成的单位向量，例如(0，1)、(1，-1)、(0，-1)、(-1，-1)、(-1，0)、(-1，1)、(0，1)和(1，1)。上述预设角度是指插槽即位图图像的坐标系统映射到第一目标模型的坐标系(即世界坐标系)时两个坐标系形成的夹角，该夹角会随着第一目标模型的坐标系的变化而变化，即用户旋转模型以调整观看视角时，插槽的插入角度即上述预设角度会同步变化。可理解的是，插槽的坐标系和世界坐标系的映射关系可以从生成模型的应用程序中提取或者预先设置。
本步骤中，可视化平台可以根据目标点确定待处理像素。可视化平台可以获取位图图像中满足第一筛选条件的候选像素，效果如图9所示，图9中黑色点表示满足第一筛选条件的候选像素，圆圈表示不满足第一筛选条件的候选像素。其中，第一筛选条件包括以下至少一种：候选像素的像素值中红色像素值小于或等于红色像素阈值，绿色像素值超过绿色像素阈值且蓝色像素值超过第一蓝色像素阈值，蓝色像素值超过第二蓝色像素阈值；所述第二蓝色像素阈值大于所述第一蓝色像素阈值。本步骤中通过设置第一筛选条件可以保证水域的颜色偏向于蓝色或者绿色而不是红色，有利于提升仿真效果。
可视化平台可以根据位图图像的尺寸和显示屏显示区域的尺寸确定位图图像中相邻两个像素之间的间隔距离，效果如图9中距离f。其中，第一目标模型或者后续的目标模型均需要显示屏显示区域内进行显示，因此显示区域的尺寸同样会影响到位置图片的相邻像素之间的间隔距离。在确定出显示区域的尺寸后，可以同步确定出目标区域的尺寸；由于位图图像的分辨率是已知的，因此可以确定出位图图像中相邻两个像素之间的间隔距离。通过设置间隔距离可以使两条水纹之间保持间隔，与现实生活中的水纹保持相同效果，提升观看体验。
需要说明的是，上述内容描述是利用位图尺寸和显示屏显示区域的尺寸来确定间隔距离的方案，实际应用中，上述间隔距离还可以根据经验值来设置，例如微风时将间隔距离设置为3-5个像素，大风时将间隔距离设置为10-15个像素，同样可以实现本公开的方案。
在确定不满足第二筛选条件时，可视化平台可以重复执行以指定点为起点，向不同方向依次移动所述间隔距离直至对应位置的像素是非候选像素或者超过所述位图图像的边界为止的步骤，确定对应位置的候选像素为待处理像素；其中所述第二筛选条件包括移动间隔距离后对应位置的像素位于位图图像之外或者没有像素，并且所述指定点包括目标点或者非候选像素之后的第一个候选像素。可理解的是，本部分内容可以是一个迭代步骤，即：第一次，以目标点为基准，可理解为石子落入位置，可以参考图8中x0处作为目标点。然后，目标点相邻的候选像素为待处理像素，如右侧的x处像素为待处理像素，处理后可以得到第一条或者第一圈水纹(即波浪的波峰)。之后，移动上述间隔距离后，再将此处对应的候选像素作为待处理像素，处理后可以得到第二条或者第二圈水纹；以此类推，按照“水纹—正常—水纹—正常……”的顺序，直至位图图像的边界为止。
实际应用中，考虑到第一次在向目标点的8个方向扩展水纹时，参见图10，图10中(a)图示出了目标点g，(b)图示出了向满足要求的5个方向扩展水纹，对于每个方向而言均是按照上述实施例中方案调整待处理像素以获得水纹，后续扩展也是按照相同方向继续扩展，遇到候选像素则调整像素亮度形成水纹，图10中(c)图示出了向左侧移动3次后形成水纹1和水纹2的效果。当移动间隔距离后对应的像素不是候选像素(如像素A)时停止以目标点g为基准的扩展过程。然后继续延期各方向找到候选像素，并将该候选像素作为指定点继续向8个方向扩展，如图10中(c)图示出了向左找到指定点g1的效果，此时指定点g1变换为与目标点具有相同地位的基准点，后续扩展过程与以目标点向外扩展过程相同，在此不再赘述。基于图10所示原理，继续查找指定点和扩展水纹，直到扩展到边界或者不是候选像素为止。这样，通过上述扩展方式可以使水域布满水纹。
需要说明的是，以指定点为基准向8个方向扩展水纹适用于石子或者雨点落入水域的场景，此时以指定点为圆心形成一圈圈的波纹。考虑到较大面积的水域，例如湖泊、海洋等，水纹是向岸边移动的，此时可以向指定点靠近岸边的4个方向扩展水纹，后续出现的指定点同理，从而形成持续的向岸边移动的水纹，使水纹与仿真场景相匹配。技 术人员可以根据具体场景选择合适的方向向量，以保证水纹的流向和朝向。其中流向是指水纹移动的方向，例如海洋内的水纹是从海洋深处流向岸边。朝向是指水纹展示给用户的朝向，即使用者在不同视角观看水纹时看到水纹的角度，例如从水纹正面看到一条水纹，并且当模型旋转90度(可理解为预设角度改变量为90度)后从水纹侧面看到一个呈现中间高且两侧低的山形浪头。
需要说明的是，考虑到位图图像中满足要求的待处理像素的占比接近一半或者少于一半，即小于或等于50％，例如30％。基于此，对于整个位图图像而言，相邻两个指定点之间的平均距离约为2-3个像素，那么对于每个指定点而言，其形成第一条或者第一圈水纹后将无法继续延伸；从整体上看整个位图图像可以形成多条或者多圈水纹，达到在位图图像上形成水纹的效果。也就是说，本示例中结合间隔距离以及不满足要求的像素对应的间隔两者可以保证相邻两条水纹之间的最终间隔，达到从视觉上看到两条水纹或者两条水纹有较大间隔的最终效果，可视化平台可以根据所述变换数据和所述待处理像素确定所述位图图像对应的变换矩阵。
本步骤中，考虑到位图图像中不同水纹的区别仅在于方向向量的改变，或者说，不同的待处理像素在目标点的不同方位。因此，对于不同的水纹，待处理像素的变换数据中相关联的预设角度不变，仅方向向量发生变化。
因此，可视化平台可以确定待处理像素的方向向量。结合上述各实施例所示例的内容，上述方向向量与水域所处场景和预设角度(如指向哪个方向)相关，其中水域所处场景决定水纹向1、4或8个等方向扩展，从而使得指定点有1、4或8个等方向的方向向量，以及决定与该指定点相关联各个方向上的待处理像素使用哪个方向向量；预设角度决定水纹的传播方向，从而决定选择待处理像素使用哪个方向向量，例如预设角度为0度时可以看到水纹正面即一条水纹，此时可以为待处理像素选择指向左或者向右的方向向量；当模型旋转90度即预设角度改变量为90度时，可以从水纹侧面看到山形浪头，此时为待处理像素选择指向或者远离显示屏的方向向量。需要说明的是，为了形象说明，选择方向向量的过程是从使用者看到显示屏的角度来说明的，实际应用中可以根据世界坐标系和位图图像坐标系的映射关系进行转换。
然后，可视化平台可以将各个待处理像素的方向向量和预设角度写入变换矩阵，并且待处理像素之外像素的位置处写入常数1(表示无需改变)，最终确定第一图像对应的变换矩阵。
可视化平台可以根据所述变换矩阵调整所述位图图像，得到所述第一图像。可理解 的是，可视化平台按照第一图像中像素及变换矩阵中变换数据的对应关系，获取两者的乘积，即对第一图像中待处理数据的像素值进行更新，从而得到第二图像。
本实施例中，上述变换矩阵可以用于指示调整哪个位置的像素以形成水纹。本步骤中调整像素值实质上调整像素的亮度值，水纹位置像素采用较高亮度，而其他位置像素采用正常亮度。对于位图图像中需要调整的像素值，亮度和对比度调节属于图像的灰度线性变换，参见以下公式：
y＝[x-127.5*(1-B)]*k+127.5*(1+B)；
式中，x为调节前的像素值，y为调节后的像素值。B取值[-1,1]，调节亮度；k调节对比度，arctan(k)取值[1，89]，k＝tan((45+44*c)/180*pi)；其中c取值预设角度，通常用c来设置对比度。
在一示例中，可视化平台可以通过以下方式来调整像素的亮度和对比度：
当B＝0时，y＝(x-127.5)*k+127.5；此时只调节对比度。
当c＝0时，k＝1，y＝x+255*B，此时只调节亮度。
需要说明的是，技术人员可以根据上述调整原理来调整像素的亮度和对比度，在此不再赘述。
本实施例中，对所述第一图像进行处理得到第二图像。
在一实施例中，可视化平台可以对第一图像进行处理以获得第二图像。例如可视化平台可以对第一图像进行菲涅尔变换处理，该菲涅尔变换可理解为傅里叶变化，其目的是为了形成任何连续测量的时序或信号，并采用不同频率的正弦波信号的无限叠加。这样，本实施例中通过莫涅尔变换可以找到后续基准点向8个方向扩展时出现反方向的水纹(或者回波)，该回波对于之前基准点产生的水纹属于噪声信号，然后去掉上述回波信号对应频率的正弦波信号，可以得到第二图像。本实施例中的方案适于大面积水域且水纹流向同一个方向的场景，如大海中海浪均朝向岸边流动，通过抗干扰处理可以保证水纹的准确性。
在一实施例中，可视化平台内设有噪声源，该噪声源可以包括生成蒙特卡洛随机数和生成噪声源参数数据，即该噪声源先生成蒙特卡洛随机数，然后再将上述蒙特卡洛随机数传入噪声源参数，从而生成噪声源参数数据。该噪声源参数数据可以包括噪声源不同位置和入射角度，其中噪声源可以等同于目标点且入射角度等同于预设角度，可 以适用于水域中下雨等场景，这些噪声源产生的水纹同样会干扰到目标点所产生的水纹。本实施例中可以通过对第一图像进行正弦变换，从而将目标点和噪声源对应的水纹叠加，得到第二图像，并将该第二图像作为目标区域对应的插槽。本实施例中通过叠加噪声数据可以仿真出不同水纹相叠加的效果，可以保证水纹的准确性。
本实施例中，将所述插槽贴合到所述第一目标模型得到第二目标模型，所述第二目标模型的目标区域呈现水纹效果如图11所示。
需要说明的是，为第一目标模型添加水纹的过程是在可视化平台的内存中完成处理，这样在获取插槽的过程中可以预先为位图图像分配内存区域，对位图图像中像素值更新过程中仅需要在位图图像上更新即可，从而使水纹在空间的z轴方向上不会占用空间，仅需要调整加载的角度即可形成不同水纹；并且无需再分配内存空间，从而可以提升内存利用率。
本实施例中，在获取第二目标模型后，可视化平台可以将内存的第二目标模型交换到显存内，由显存完成目标模型的渲染等显示工作，在此不再赘述。可理解的是，对于显存而言，第二图像和位图图像并没有增加渲染参数，从而在第二目标模型需要水域的部位使用上述方法，有利于提升仿真效果。
本公开提供的技术方案中，可以在检测到第一目标模型在仿真过程中有获取水纹的需求时获取水纹对应的目标区域，并获取所述目标区域对应的插槽；然后，将所述插槽贴合到所述第一目标模型得到目标模型，所述目标模型的目标区域呈现水纹效果。这样，本实施例中，将带有水纹的插槽贴合到第一目标模型即可使目标模型携带水纹，仅需要为插槽开辟内存和显存即可而无需额外增加内存和显存，有利于提升仿真效率。
下面描述为第一目标模型添加水纹的实现过程。
可视化平台内存储水纹仿真SDK，在仿真过程中可以调用运行上述SDK。可视化平台可以通过动态链接库或者静态链接库接口在本地数据库中检索基本纹理本地数据库和干扰参数数据库，本地数据库和干扰参数数据库可以设置在工艺工法数据库之内。其中基本纹理数据库即是上述的位图图像，干扰参数数据库即是上述的噪声数据。实际应用中，可以将图1所示步骤集成到一个模块中，仅提供接口和静态资源包(如预制的基本纹理图片，或者波浪的高度，深度等参数，可设置)。
使用者可以在交互界面内选择第一目标模型的目标区域欲使用的插槽，可视化平台在检测到使用者所选择的插槽后可以获取到该插槽对应的基本纹理数据和干扰参 数数据。然后，可视化平台可以通过数据逻辑层调用广度计算模型、折射计算模型和法线偏移计算模型对上述基本纹理数据和干扰参数数据进行处理。例如广度计算模型可以获取第一目标模型中的镂空区域(或者目标区域)的起始点和终点，然后确定出目标区域在显示区域内的范围。折射计算模型可以获取预制的基本纹理图片(即位图图像)置入3D世界的角度，即获得预设角度；以及获取水域场景处光或风传入角度等，以确定水纹的流向和朝向。法线偏移计算模型可以获取基本纹理图片内满足像素/RGB值要求(即第一筛选条件)的候选像素的坐标，并获取指定点的坐标及其法线。可理解的是，在预设角度未发生变化且光或风传入角度发生变化(即噪声数据变化)时，同样可以引起位图图像中目标点或指定点处法线的变化，进而引进水纹的变化。之后，可视化平台对上述基本纹理图像处理后可以获得插槽。之后在将插槽贴合到第一目标模型之后可以得到目标模型。最后，目标模型可以在外部预览界面上显示，此时。
需要说明的是，上述内容描述从一个角度将插槽插入到OSG引擎的方案。实际应用中，可视化平台可以将插槽直接加载到OSG引擎中的任意位置，此时可以调整加载的角度(即在视线不变的情况下，通过调整法线的指向来调整预设角度的大小)，即可在目标区域内形成相应的水纹。并且，随之目标模型在空间角度的变换，上述加载的角度也随之改变，那么所显示水纹的流向和朝向也随之改变，达到不同视角观看到不同流向和朝向的水纹的效果。
本领域技术人员在考虑说明书及实践这里公开的公开后，将容易想到本公开的其它实施方案。本公开旨在涵盖任何变型、用途或者适应性变化，这些变型、用途或者适应性变化遵循本公开的一般性原理并包括本公开未公开的本技术领域中的公知常识或惯用技术手段。说明书和实施例仅被视为示例性的，本公开的真正范围和精神由下面的权利要求指出。
应当理解的是，本公开并不局限于上面已经描述并在附图中示出的精确结构，并且可以在不脱离其范围进行各种修改和改变。本公开的范围仅由所附的权利要求来限制。
