具体实施方式
为了使本技术领域的人员更好地理解本说明书中的技术方案，下面将结合本说明书实施例中的附图，对本说明书实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本说明书一部分实施例，而不是全部的实施例。基于本说明书中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都应当属于本说明书保护的范围。
随着计算机网络技术的发展，人们可以通过电子地图了解世界各地的地理位置等信息。通常情况下地图或者电子地图是以省份、国家来进行区域的划分，但是，有些情况下，可能需要将一些指定的区域在地图上进行合并，如：将中国地图中的东北三省合并成东北区，以方便用户对东北区域的进行整体的了解认识。
本说明书实施例提供的地图区域合并的数据处理方法，通过设置统一的透明度，在合并地图区域时，重合的部分透明度会发生变化，基于地图图像中透明度的变化，将指定的区域进行合并。基于像素点透明度的变化，合并指定的地图区域，方法简单快捷，不需要复杂的数学计算，合并后的地图区域可以作为一个整体进行交互，适用性强。
本申请实施例中合并地图区域的数据处理过程可以在客户端上进行如：智能手机、平板电脑、智能可穿戴设备(智能手表、虚拟现实眼镜、虚拟现实头盔等)等电子设备。具体可以在客户端的浏览器端进行，如：PC浏览器端、移动浏览器端、服务器端web容器等。
具体地，图1是本说明书提供的一个实施例中的地图区域合并的数据处理方法的流程示意图，如图1所示，本说明书实施例提供的地图区域合并的数据处理方法，包括：
S2、使用预设透明度的线条绘制待合并区域的地图图像，生成初始合并地图图像。
待合并区域可以包括多个地图区域，如：东北三省中的辽宁省、吉林省、黑龙江省三个省份可以表示三个待合并区域，可以在同一个画布(画布可以表示用于绘制图形的组件或区域)或其他地图绘制区域使用预设透明度的线条绘制出待合并区域的地图图像。例如：图2是本说明书一个实施例中东北地区的初始合并地图图像的示意图，如图2所示，可以根据东北三省的经纬度信息，在同一个画布中按照辽宁省、吉林省、黑龙江省的相对位置分别绘制出辽宁省、吉林省、黑龙江省的地图图像，三个省份的地图图像共同组成东北地区的初始合并地图图像，可以看出初始合并地图图像中相邻的待合并区域之间可能会出现边界重合。如图2所示，在绘制待合并区域的地图图像时，可以只绘制出各个待合并区域的轮廓线即边界线，边界线以内的区域可以表示该待合并区域。
其中，绘制待合并区域的地图图像时，本说明书一个实施例中使用预设透明度的线条进行绘制，预设透明度可以根据实际需要进行选取，通常情况下预设透明度可以设置在0-1之间，本说明书一个实施例中预设透明度可以为0.5，这样设置可以方便后续像素点的检测。
此外，在绘制各个待合并地图区域时，不同的待合并地图区域可以是使用相同颜色的线条绘制，也可以使用不同颜色的线条进行绘制。如：东北三省地图区域作为待合并区域时，可以在同一个画布中都使用黑色(或其他颜色如：红色、蓝色等)、透明度为0.5的线条绘制出辽宁省、吉林省、黑龙江省的地图图像，将三个省份的地图图像的整体作为东北地区的初始合并图像。也可以使用黑色、透明度为0.5的线条绘制辽宁省的地图图像，使用红色、透明度为0.5的线条绘制吉林省的地图图像，使用蓝色、透明度为0.5的线条绘制黑龙江省的地图图像，将三个省份的地图图像的整体作为东北地区的初始合并图像。即本说明书一个实施例中在绘制待合并区域中各个区域的地图图像时，不同区域的地图图像可以使用相同的透明度的线条，但是线条颜色可以不进行具体的限定。
在绘制待合并区域的地图图像时，可以通过导入GeoJSON数据，然后用程序在画布上绘制出地图。GeoJSON是一种对各种地理数据结构进行编码的格式，是一种地图数据的组织格式，可以通过解析这种数据绘制出地图。
S4、获取所述初始合并地图图像中像素点的透明度。
在生成初始合并地图图像后，可以获取初始合并地图图像中的各个像素点的透明度。本说明书一个实施例中，在绘制待合并区域的地图图像时，可以将待合并区域的经纬度信息转化为坐标信息。根据待合并区域的坐标信息，可以遍历初始合并地图图像中待合并区域内的各个像素点，即可以遍历初始合并地图图像中待合并区域内的每个原始数据(包含经纬度信息的数据点或者坐标信息的数据点)对应的画布像素点，获取初始合并地图图像中待合并区域内的像素点对应的透明度。可以基于染色技术获取各个像素点的透明度，具体方法本申请实施例不作具体限定。
通过遍历待合并区域内部的像素点，获得各个像素点的透明度变化，方法简单，并且可以减少待合并区域外部像素点的检测，提高了数据处理的速度。
S6、将所述像素点的透明度与所述预设透明度相同的像素点作为目标像素点，根据所述目标像素点生成合并后的目标合并地图图像。
在获取到初始合并地图图像中像素点的透明度后，可以将像素点的透明度和在绘制待合并区域的地图图像时使用的线条的预设透明度进行对比，将透明度与预设透明度相同的像素点作为目标像素点。例如：在绘制待合并区域的地图图像时使用的预设透明度为0.5，则可以将初始合并地图图像中透明度为0.5的像素点作为目标像素点。利用目标像素点可以生成合并后的目标合并地图图像，完成地图区域的合并。
本说明书一个实施例中，可以提取出目标像素点的坐标信息，将目标像素点对应的坐标信息导出，利用目标像素点对应的坐标信息的集合生成目标合并地图图像。如：若在绘制待合并区域的地图图像时使用的预设透明度为0.5，可以将初始合并地图图像中透明度为0.5的像素点作为目标像素点，提取目标像素点的坐标信息，可以将目标像素点的坐标信息保存在坐标点集合中，可以将所有目标像素点的坐标信息组成的坐标点集合导出。根据目标像素点的坐标集合绘制出目标合成地图图像，目标合成地图图像可以由待合并区域的边界图像组成，此时生成的待合并区域的边界图像中可以不包括待合并区域的边界重叠的部分。
例如：本说明书一个实施例可以在画布或者地图绘制区域使用黑色、透明度为0.5的线条绘制出待合并区域的地图图像，待合并区域的地图图像中可以包括待合并区域的边界图像，待合并区域的地图图像可以组成初始合并地图图像，具体可以参考图2中东北地图的初始合并地图图像示意图。遍历初始合并地图图像中待合并区域内的像素点， 待合并区域的边界处未重叠的部分像素点的透明度为0.5，边界重叠的部分像素点的透明度通常大于0.5，边界图像内部的其他区域因未绘制图像内容，像素点的透明度为0。可以将透明度为0.5的像素点作为目标像素点，即将边界图像中未重叠的部分的像素点作为目标像素点。目标像素点组合在一起，可以表示合并后的待合并区域的边界图像，此时，合并后的边界图像中不包括各个待合并区域的重叠部分，可以表示各待合并区域整体的边界轮廓。可以提取并保存目标像素点的坐标信息，将目标像素点对应的坐标信息导出可以生成合并后的目标合并地图图像。图3是本说明书一个实施例中合并后的东北地区的目标合并地图图像示意图，如图3所示，本说明书一个实施例中合并后的目标地图图像可以将各待合并区域的边界重叠部分去除，只保留边界未重叠部分，直观的表示地图区域合并的效果，方便用户查看。
图4(a)-4(b)是本说明书一个实施例中透明度变化检测示意图，如图4(a)所示，图中将两个透明度为0.5的图像进行部分叠加，从图中可以看出中间叠加部分的图像的透明度大于其他未叠加部分的图像的透明度。同样的，如图4(b)所示，将两个没有边框的透明度为0.5的图像的进行部分叠加，可以看出，中间重叠部分的图像的透明度大于其他未叠加部分的图像的透明度。本说明书实施例中，通过检测像素点的透明度的变化，可以准确快速的检测出待合并区域中哪些部分发生重叠，哪些部分未重叠，以实现快速准确的生成合并后的地图图像。
此外，本申请实施例还可以根据待合并区域所处的地理位置，为合并后的目标合并地图图像进行命名，例如：图3中将合并后的东北三省命名为东北区。
本说明书提供的地图区域合并的数据处理方法，可以通过画布上染色技术检测像素点的透明度是否有变化，基于地图合并时重叠部分的像素点的透明度与未重叠部分的像素点的透明度不同，筛选出边界重叠的像素点和边界未重叠的像素点，进一步基于边界未重叠的像素点生成合并后的地图图像。方法简单快捷，不需要复杂的数据处理，并且能够准确的检测出边界重叠部分，使得地图区域的合并更加准确快速，合并后的地图区域可以作为一个整体进行交互，方便后续使用，适用性广。
在上述实施例的基础上，本说明书一个实施例中，所述使用预设透明度的线条绘制待合并区域的地图图像，生成初始合并地图图像，可以包括：
在第一地图绘制区域获取用户选择的所述待合并区域；
根据用户选择的所述待合并区域，在第二地图绘制区域使用所述预设透明度的线条 绘制待合并区域的地图图像，生成所述初始合并地图图像。
具体地，用户在第一地图绘制区域(如某客户端的画布中)中查看地图时，若需要将部分地图区域进行合并，如需要将东北三省的地图区域进行合并，则用户可以通过点击或其他操作选择需要合并的待合并区域。如：用户在第一地图绘制区域中通过导入GeoJSON数据绘制出完整的地图(如绘制出中国地图)，并通过点击绘制出的中国地图中的东北三省辽宁省、吉林省、黑龙江省，选择出待合并区域。识别出用户选择的待合并区域后，可以在第二地图绘制区域(第二地图绘制区域可以使用隐藏画布)使用预设透明度的线条绘制出待合并区域的地图图像，生成初始合并地图图像，具体可以参考上述实施例生成初始合并地图图像，此处不再赘述。基于用户的选择生成初始合并地图图像，用户可以根据实际需要选择待合并区域，进行地图区域的合并，方法简单，灵活，提高了用户体验。
在上述实施例的基础上，本说明书一个实施例中，所述根据所述目标像素点生成合并后的目标合并地图图像，可以包括：
将所述初始合并地图图像中的所述目标像素点之外的像素点从所述初始合并地图图像中剔除；
将所述初始合并地图图像中所述目标像素点组成的地图图像作为所述目标合并地图图像。
具体地，在确定出目标像素点，基于目标像素点生成目标合并地图图像时，可以将初始合并地图图像中的非目标像素点(即除去目标像素点之外的像素点)从初始合并地图图像中剔除，此时，初始合并地图图像中只剩下目标像素点，可以将剩下的目标像素点合并组成合并后的目标合并地图图像。如：上述实施例中在第二地图绘制区域中将非目标像素点剔除，保留目标像素点，则第二地图绘制区域中剩余的目标像素点组成的图像即可以表示合并后的目标合并地图图像。
将透明度不符合要求的非目标像素点从初始合并地图图像中剔除，剩余的目标像素点直接生成合并后的目标合并地图图像，方法简单，地图区域合并准确。
在剔除非目标像素点后，可以将非目标像素点的位置处的颜色设置为与初始合并地图图像中边界内部区域(即待合并区域内部区域)的像素点的颜色相同。这样可以避免剔除非目标像素点后，非目标像素点的颜色与待合并区域边界内部其他区域的颜色不同，影响合并后地图图像的显示效果。如：若在绘制待合并区域的地图图像生成初始合并地 图图像时，初始合并地图图像具有底色如：待合并区域的边界内部区域使用红色像素点填充，则在剔除非目标像素点后，非目标像素点位置处的颜色可能会变成白色或无色，与待合并区域的边界内部区域其他像素点的颜色不同，影响合并地图图像的显示效果。可以在剔除非目标像素点后，将非目标像素点处的颜色设置为红色，与待合并区域的边界内部区域的颜色保持一致，提高合并后地图图像的显示效果。若待合并区域中各个区域边界内部使用不同的颜色进行填充，即初始合并地图图像中非边界处有多种颜色，则可以取非目标像素点临近的任意一个像素点的颜色作为该非目标像素点剔除后该位置处的颜色。
本说明书提供的地图区域合并的数据处理方法，通过设置统一的透明度，在合并地图区域时，重合的部分透明度会发生变化，基于地图图像中透明度的变化，将指定的区域进行合并。基于像素点透明度的变化，合并指定的地图区域，方法简单快捷，不需要复杂的数学计算，合并后的地图区域可以作为一个整体进行交互，适用性强。
本说明书中上述方法的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。相关之处参见方法实施例的部分说明即可。

在20世纪90年代，对于一个技术的改进可以很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field Programmable Gate Array，FPGA))就是这样一种集成电路，其逻辑功能由用户对器件编程来确定。由设计人员自行编程来把一个数字系统“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。
控制器可以按任何适当的方式实现，例如，控制器可以采取例如微处理器或处理器以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit，ASIC)、可编程逻辑控制器和嵌入微控制器的形式，控制器的例子包括但不限于以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320，存储器控制器还可以被实现为存储器的控制逻辑的一部分。本领域技术人员也知道，除了以纯计算机可读程序代码方式实现控制器以外，完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件，而对其内包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至，可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的 结构。
上述实施例阐明的系统、装置、模块或单元，具体可以由计算机芯片或实体实现，或者由具有某种功能的产品来实现。一种典型的实现设备为计算机。具体的，计算机例如可以为个人计算机、膝上型计算机、车载人机交互设备、蜂窝电话、相机电话、智能电话、个人数字助理、媒体播放器、导航设备、电子邮件设备、游戏控制台、平板计算机、可穿戴设备或者这些设备中的任何设备的组合。
虽然本说明书一个或多个实施例提供了如实施例或流程图所述的方法操作步骤，但基于常规或者无创造性的手段可以包括更多或者更少的操作步骤。实施例中列举的步骤顺序仅仅为众多步骤执行顺序中的一种方式，不代表唯一的执行顺序。在实际中的装置或终端产品执行时，可以按照实施例或者附图所示的方法顺序执行或者并行执行(例如并行处理器或者多线程处理的环境，甚至为分布式数据处理环境)。术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、产品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、产品或者设备所固有的要素。在没有更多限制的情况下，并不排除在包括所述要素的过程、方法、产品或者设备中还存在另外的相同或等同要素。第一，第二等词语用来表示名称，而并不表示任何特定的顺序。
为了描述的方便，描述以上装置时以功能分为各种模块分别描述。当然，在实施本说明书一个或多个时可以把各模块的功能在同一个或多个软件和/或硬件中实现，也可以将实现同一功能的模块由多个子模块或子单元的组合实现等。以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
