具体实施方式
为了满足用户三维场景图像的应用需求，三维场景图像的建立人员需要从GIS数据提供公司购买数据使用权限。在一些小范围三维建图场景(比如，校园、工业园区、商业区)中，用户通常想要低成本、短时间内实现三维图像的建立。一般来说，开源免费的GIS数据不够精细，无法满足园区、校园等小范围三维场景图像的生成需求，而采购商用GIS数据的成本太高，对于小的应用场景(比如，园区三维图像、校园三维图像)来说难以承受这笔数据费用支出。此外，也可以通过人工建模方式实现，比如，3DSMax、C4D、Sketch Up等传统的三维建模软件中，直接将现实中的场景通过人工建模的形式进行还原。但是需要专业技术人员进行大量工作才能完成，所需要的人工成本和时间成本都比较高。因此，本申请提出一种能够简便、低成本生成三维场景图像的技术方案。
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
在本申请的说明书、权利要求书及上述附图中描述的一些流程中，包 含了按照特定顺序出现的多个操作，这些操作可以不按照其在本文中出现的顺序来执行或并行执行。操作的序号如101、102等，仅仅是用于区分各个不同的操作，序号本身不代表任何的执行顺序。另外，这些流程可以包括更多或更少的操作，并且这些操作可以按顺序执行或并行执行。需要说明的是，本文中的“第一”、“第二”等描述，是用于区分不同的消息、设备、模块等，不代表先后顺序，也不限定“第一”和“第二”是不同的类型。此外，下文描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1为本申请实施例提供的一种数据处理方法的流程示意图。可以应用于图像生成工具。从图1中可以看到，包括如下步骤：
101：获取至少一类元素的矢量图数据。
102：对所述至少一类元素的矢量图数据进行解析，得到所述至少一类元素的轮廓点。
103：确定所述至少一类元素的轮廓点在一空间坐标系下的坐标信息。
104：根据所述至少一类元素的轮廓点的坐标信息，生成三维场景图像。
这里所说的元素，可以是通过实际场景所采集到的目标图中所包含的道路、山、水、单体建筑、密集建筑群等等。这里所说的矢量图数据可以是SVG格式的矢量图中所包含的数据。在SVG格式矢量图中包含有多种二维图元文本数据，比如，矩形<rect>、圆形<circle>、椭圆形<ellipse>、线<line>、折线<polyline>、路径<path>等。因此，当需要输入矢量图数据的时候，可以通过直接输入SVG格式矢量图的方式完成矢量图数据的输入，之后由计算机后台可以容易获取到所需的矢量图数据。需要说明的是，这些元素的矢量图数据都是相互独立的，换言之，每个SVG格式矢量图中只包含有一种类型元素，比如，只包含有道路元素的矢量图数据，以便分别进行解析、可视化处理。
如图2为本申请实施例中举例说明的多类型元素矢量图的示意图。图2中包含有多个由轮廓线构成的矢量图，分别是，平地轮廓矢量图、道路轮廓矢量图、楼群(密集建筑群)矢量图、建筑(单体建筑)矢量图、小路矢量图。这些元素矢量图都是相互独立的，以便分别进行解析、可视化处理。这里的矢量图数据能够准确的反应出目标图中所包含的至少一类元素的图像信息。
下面将对矢量图数据的获取方式进行举例说明。如图3为本申请实施例提供的一种获取矢量图数据方法的流程示意图。从图3中可以看到，具体包括如下步骤：
301：获取目标图。
302：对所述目标图进行元素拆分，得到至少一类元素的轮廓信息。
303：根据至少一类元素的轮廓信息，得到至少一类元素的矢量图数据。
在实际应用中可以利用图像采集设备对将要建立三维场景图像的实际场景进行图像采集，得到目标图。还可以直接利用现有免费地图软件获取到所需区域的平面地图。需要说明的是，在基于平面地图获取所需目标图的时候，需要根据实际清晰度或展示效果需求，对平面地图进行缩放，以便能够清晰展示单体楼、道路等所需元素。如果需要建立三维场景图的面积比较大，可以分割为多张目标图，然后在进行拼接。
具体来说，在进行目标图生成的时候，采用俯视角获取当前待三维场景的平面地图。从目标图中可以清楚表示各种类型元素，比如，道路、山、水、单体建筑、密集建筑群等。这里所说的目标图中可以清楚表示各种类型元素可以理解为，人或者计算机能够准确的识别出元素外轮廓，以便能够进行准确的轮廓描绘，生成轮廓线或轮廓点。当然根据需要，也可以进一步从目标图中准确识别出各个元素的类型。
例如，如图4为本申请实施例提供的目标图的示意图，在从图4中可以看到包含有各种类型元素，道路、单体建筑、密集建筑群等。进一步，如图5为本申请实施例提供的轮廓描绘后矢量图的示意图，对目标图中的各个元素分类别进行轮廓描绘，得到如图5所示的整体绘制轮廓图像。比如，通过线条对道路元素进行描绘，得到交错网状道路；通过线条对单体建筑进行轮廓描绘，并进行元素颜色填充，得到单体建筑元素描绘结果；通过线条对密集建筑群进行轮廓描绘，并对轮廓描绘完成的元素进行颜色填充，得到密集建筑群元素描绘结果；通过线条对平地(比如，公园、空地等)进行轮廓描绘，并进行元素颜色填充，得到平地元素描绘结果；通过细线条(比道路描绘线条细)进行小路轮廓描绘，得到通过细线条标识的交错网状小路。
在实际进行绘制的时候，需要分层次进行，也就是先整体绘制轮廓，然后对目标图进行放大后针对细节轮廓的进行绘制。也可以先对目标图进行放大情况下，分多个片区或者分多个元素逐个绘制。并将绘制得到的绘制完成后根据元素类型分开保存，得到如图2所示的只包含有一种元素类型的轮廓矢量图(Scalable Vector Graphics，SVG)。
此外，也可以先拆分后绘制。比如，根据各元素类型对目标图进行拆分，生成仅包含单一元素类型的元素矢量图。然后，对各元素矢量图中的元素进行轮廓描述；生成所述轮廓矢量图。
在得到各个元素的轮廓矢量图之后，如图6为本申请实施例提供的输 入矢量图的示意图。如图6所示将这些轮廓矢量图输入到交互界面，在该界面中可以看到拆分后的轮廓矢量图的展示效果。在一些场景中，也可以基于其中任一元素建立三维图像。
在得到SVG格式的矢量图数据之后，可以进一步将轮廓线转换为轮廓点。对所述至少一类元素中的第一类元素的矢量图数据进行解析，得到所述第一类元素的轮廓点，包括：根据所述第一类元素的矢量图数据，确定所述第一类元素的轮廓线信息；基于所述第一类元素的轮廓线信息，得到反映所述第一类元素轮廓的轮廓点。
在本实施例中，矢量图数据可以通过SVG格式的轮廓矢量图形式表示。因为在轮廓矢量图中包含有二维图元文本数据，然后可以利用生成式设计算法对轮廓矢量图中二维图元文本数据进行解析处理。
举例来说，一个轮廓矢量图可以是一个SVG格式文件，获取SVG格式文件内<path>，<polygon>等二维图元文本数据，进而在服务端NodeJS对上述二维图元文本数据进行解析，得到含有三维坐标信息的轮廓点。如图7为本申请实施例提供的轮廓线转换为轮廓点的示意图，所能呈现给用户的直观感受是如图7所示的效果，从轮廓线构成的矢量图转换为由轮廓点构成的矢量图。
进一步地，根据所述至少一类元素的轮廓点的坐标信息，对所述至少一类元素进行建模，得到至少一类元素分别对应的三维模型。根据所述至少一类元素的轮廓点的坐标信息，将至少一类元素分别对应的三维模型组合，生成所述三维场景图像。
在实际应用中，可以分别基于各个类型元素的轮廓点的坐标信息先分别生成仅包含一类别元素的三维模型。比如，如图8a所示得到群楼三维模型、地三维模型。
在进行三维模型建模的时候，可以将各类型元素放到同一三维空间中同时进行建模工作。因为进行三维模型建模的时候，要充分考虑到各个元素三维空间位置关系、比例关系。若分别针对各个轮廓矢量图进行建模，然后在进行三维模型的合并的时候，可能会出现某两个相邻图像之间存在干扰，或者比例关系与实际情况相差很大。
图8a、8b为本申请实施例提供的三维模型生成组合的示意图。如图8a所示，将各个元素处理生成三维模型，包括单体建筑、密集建筑、道路、地、水分别对应的三维模型，进而将这些不同元素的三维模型组合到一起，得到如图8b所示的完整的三维场景图像。
将解析后的由所述轮廓点构成的轮廓矢量图进行可视化处理(比如，利用着色语音GLSL(OpenGL Shading Language)实现可视化处理)，生 成各所述元素对应的元素三维模型。
在生成三维场景图像之后，可以将其发送给客户端进行渲染处理。具体来说，对所述各类型元素进行可视化处理，生成各所述元素对应的元素三维模型；根据各所述元素的元素类型，对各所述元素三维模型进行可视化渲染；基于渲染后的各类型所述元素三维模型，生成用于表示所述场景的三维场景图像。
在进行可视化渲染的时候，针对不同的元素类型所要渲染出的效果不同。比如，针对高层建筑，渲染出高度差的效果。比如，针对道路和小路，想要渲染出具有不同等级、不同宽度的路的效果。
在实际应用中，用户可以在客户端对渲染风格进行选择，比如，可以选择商务蓝风格、田园绿风格等等。进而，由客户端对元素三维模型进行可视化渲染，从而输出完整的三维场景图像。
基于同样的思路，本申请实施例还提供一种数据处理方法。如图9为本申请实施例提供的另一种数据处理方法的流程示意图。从图9中可以看到包括如下步骤：
901：显示交互界面。
902：响应于用户通过所述交互界面触发的输入操作，展示用户依次输入的至少一类元素的矢量图数据。
903：响应于用户通过所述交互界面触发的三维场景图导出指令，在三维图展示界面，显示根据所述至少一类元素的矢量图数据生成的三维场景图像。
为了便于理解，下面将通过具体实施例进行举例说明。如图10为本申请实施例举例说明的生产三维场景图像的示意图。
如图10所示，在客户端的交互界面上显示有用于输入矢量图数据的展示窗口，每个单元格当中可以通过拖拽或者添加的方式，将任一类型元素的SVG格式矢量图输入到单元格当中。
进而，客户端将得到的至少一类元素对应的矢量图输入到单元格当中。发送给服务端获取到各个矢量图携带的矢量图数据。
进一步地，用户通过交互界面触发三维场景图像导出指令，比如，通过触发导出控件，在三维图展示界面上能够展示至少一类元素的矢量图数据生成的三维场景图像。在实际应用中，可以批量导入多个元素类型的矢量图数据，在导出时，可以通过三维图展示界面上同时展示多个三维场景图像。当然也可以是在后台分别生成各类型元素分别对应的单一元素三维场景图像，并在后台进行组合，得到用户可见的组合后包含所有类型元素 的三维场景图像。
具体来说，基于矢量图数据得到三维场景图像需要经过复杂的处理过程，因此，可以发送服务端进行处理。具体处理过程如下：对所述至少一类元素的矢量图数据进行解析，得到所述至少一类元素的轮廓点。确定所述至少一类元素的轮廓点在一空间坐标系下的坐标信息。根据所述至少一类元素的轮廓点的坐标信息，生成三维场景图像。具体可参考图1至图7所示实施例。
进一步地，在生成三维场景图像之后，还包括：响应于用户再所述三维图展示界面上的渲染配置操作，按照用户配置的渲染配置信息，对所述三维场景图像可视化渲染。显示渲染后的效果图。
可以看到，在交互界面中展示有多种不同风格的渲染选项，设计总体渲染风格。当然，用户也可以自己手动选择每种元素所要渲染的效果，比如，根据实际情况，将建筑渲染为灰色，将河流渲染为蓝色等等。
本申请实施例还提供一种数据处理系统。如图11为本申请实施例提供的一种数据处理系统的结构示意图，在图11中可以看到系统当中包含有客户端和服务端。其中，客户端有显示设备，便于用户能够直观的看到渲染效果以及进行相关交互操作。服务端可以是本地服务器设备，也可以是云服务器，能够为复杂计算过程提供算了支持，提高解析计算、可视化计算的处理速度。具体来说：
客户端1101，用于将用户通过交互界面输入的至少一类元素的矢量图数据发送至服务端。
服务端1102，用于获取至少一类元素的矢量图数据；对所述至少一类元素的矢量图数据进行解析，得到所述至少一类元素的轮廓点；确定所述至少一类元素的轮廓点在一空间坐标系下的坐标信息；根据所述至少一类元素的轮廓点的坐标信息，生成三维场景图像。
客户端1101，还用于接收所述服务端反馈的所述三维场景图像并进行显示。
进一步地，服务端1102，还用于：根据所述第一类元素的矢量图数据，确定所述第一类元素的轮廓线信息。基于所述第一类元素的轮廓线信息，得到反映所述第一类元素轮廓的轮廓点。
进一步地，服务端1102，还用于：根据所述至少一类元素的轮廓点的坐标信息，对所述至少一类元素进行建模，得到至少一类元素分别对应的三维模型；根据所述至少一类元素的轮廓点的坐标信息，将至少一类元素分别对应的三维模型组合，生成所述三维场景图像。
所述客户端1102还用于：获取渲染配置参数。根据所述渲染配置参数，对所述三维场景图像可视化渲染。
如图12为本申请实施例提供的一种基于SVG文件进行三维建模的方法流程示意图。具体包括如下步骤：
获取SVG格式的矢量图并将这些矢量图文件上传到交互界面，并通过客户端1101将这些轮廓矢量图所携带的矢量图数据发送给服务端1102。
服务端1102从轮廓矢量图中获取到包含的点位信息(也就是二维图元文本数据)，比如，<polygon>、<path>。进而，利用NodeJS端解析这些二维图元文本数据，得到轮廓点。在进行轮廓点计算的时候，可以利用云计算技术实现。在得到轮廓点之后，还需要进一步计算三维坐标信息。进而，基于三维坐标信息利用GLSL着色语言进行可视化处理，生成元素三维模型。将元素三维模型发送给客户端，由客户端进行渲染。在渲染的时候，可以根据场景类型(比如，是工业场景、校园场景、商务写字楼场景)提供多种可选渲染风格。在渲染过程中，用户还可以根据自己的需要对渲染风格中的色系、明暗等等进行多项选择性设置。
