Description
本申请要求于2017年10月10日提交中国专利局、申请号为201710937808.6发明名称为“二维地图转换三维地图的方法、装置和计算机存储介质”的中国专利申请的优先权，其全部内容通过引用结合在申请中。
技术领域
本发明涉及图形处理领域，尤其涉及二维地图转换三维地图的方法、装置和计算机存储介质。
背景技术
现有的三维地图主要是利用建筑物的阴影，按照比例形成的轮廓以给人们三维地图的视觉，在建筑物内部并不能生成三维地图。
在大型综合体建筑，如，购物中心、写字楼、医院等各种林立的大厦越来越多，但我们平时接触的地图却大多是二维平面的，所以根本无法体现出城市中的纵向垂直空间感，不免让人们对确切位置进行进一步确认时感到疑惑。如果能够利用现在已有的二维平面地图，为其补充上在垂直空间上缺失的那三分之一的信息，转化为三维地图，能在一定程度上让人们对地图上的位置信息有更为准确的认知，解决人们在日常出行的类似疑惑。

需要补充说明的是本实施例中的二维地图是svg地图，普通格式的地图转化为svg地图的方式步骤如下：
步骤a、将建筑物其他格式的二维地图作为绘制模板;
步骤b、新建svg文件：File --> New --> svg 点击ok;
步骤c、修改svg画布大小,使svg画布大小和其他格式的二维地图模板一致;
步骤d、如果图片与画布未重合，移动图片。
步骤e、抠取区域路径（为了轮廓更清晰，准确。可进行放大；选中钢笔，这个是点路径用的，把填充颜色调至无，边框蓝色（也可以是其他比较鲜艳的颜色，以便区分边界）；使用钢笔，在图片上选取路径；点取过程中可以使用鼠标滚轮，和下面的滚动条调整显示区域）。
步骤f、给区域添加文字：选中text工具，在对应的位置上点击后输入文字，如果位置需要调整，可以修改代码中text标签里对应的x，y值，也可以，点击黑色箭头，选中文字后拖到对应位置。

需要补充说明的是由于建筑物中包含有多个楼层，各个楼层的布局不同，可以将建筑物中的各个楼层对应的二维地图按照楼层顺序排列形成二维地图组，以利用本发明中的方法进行多次的转化形成整个建筑对应的三维地图。
在本实施例中通过将建筑物的二维地图的三维描述信息和二维地图中的二维地图元素进行解析，以将二维地图增加垂直方向上的维度，使建筑物的二维地图转换位三维地图，二维地图转换位三维地图的方式更加简单，无需复杂的算法和模型就可以实现建筑二维地图单三维地图的转换。

若没有保存二维地图对应的实景图，则将三维图单元按预设室内设施分类标准进行分类，并根据所述分类为三维图单元调加标识信息。即，在终端没有保存实景图时，将三维图单元按照预设标准进行分类，即，门店标识红色元素进行填充，厕所用蓝色的元素进行填充，楼梯设置黄色的元素填充，并设置对应的图形元素，以用户准确直观地查看。
