Description

一种多显示终端图标数据显示方法、系统和计算机存储介质
本申请要求于2020年11月27日提交中国专利局、申请号为202011363358.2、发明名称为“一种多显示终端图标数据显示方法、系统和计算机存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及计算机显示技术领域，更具体地，涉及一种多显示终端图标数据显示方法、系统和计算机存储介质。
背景技术
在地图上查询结果通常以标记点的形式展现，但是如果标记点较多，不仅会大大增加客户端的渲染时间，让客户端变得卡顿，而且会让人产生密集恐惧症。为了解决这一问题，需要一种手段能在用户有限的可视区域范围内，利用最小的区域展示出最全面的信息，而又不产生重叠覆盖。对标记点进行聚集是其中一种手段，现有技术一般会根据当前显示端的可视区域，获取对应范围内的数据后，按照预设的聚集半径，对这些数据进行聚集分析。上述现有技术局限于单个显示端中，在实际应用中，常常需要同时在多个显示端上进行可视化显示，而多个显示端的分辨率往往不是统一的，带来的缺点是多个显示端的显示范围有差异，计算得出的聚集结果也不相同，影响显示效果，做不到统一聚集结果，造成信息偏差。同时，体现在地图上的信息越来越多，可视化显示过程需要处理的数据也越来越多，大数据量同时在多个显示端进行处理，提高显示效率并保证显示效果统一是该领域内亟待解决的重要课题。
中国专利CN105278909A公开了一种多GIS显示端图标数据显示方法和系统，通过设置参考端，把参考端的地图显示范围、地图显示分辨率、聚集范围因子发送给其它端，各个端按同样的参数进行聚集计算，由此实现各个端聚集结果相同。但由于其他端依据参考端的当前地图显示范围进行聚集，而当参考端每次进行地图大小缩放时，所有显示终端(包括参考 端和其他端)都需要重新进行实时的聚集计算，显示效率较低。且当参考端是3D地图时，当前地图显示范围较难识别，影响其他端的聚集效果，聚集计算不准确且各个显示终端不统一。
发明内容
本申请旨在克服上述现有技术的至少一种缺陷(不足)，提供一种多显示终端图标数据显示方法、系统和计算机存储介质。
本申请的多显示终端图标数据显示方法包括如下步骤：在多个显示终端中选择一个作为参考终端，并获取参考终端的特征数据；其中，所述特征数据包括参考终端的相机高度Ch、相机角度Fov和地图显示像素高度Mh；将所述特征数据和待显示的经纬度点发送至除参考终端的其他显示终端；在所有显示终端中根据特征数据对待显示的经纬点坐标进行聚集，具体步骤如下：根据所述相机高度Ch、相机角度Fov和地图显示像素高度Mh构建虚拟像素空间；所述虚拟像素空间为由多个像素组成的区域，其包含的像素个数与所述相机高度Ch成反相关；将待显示的经纬点坐标映射于所述虚拟像素空间上，得到多个待聚集像素坐标，并对所述待聚集像素坐标进行聚集，形成聚集点；将所述聚集点转换为相应的经纬度点供显示终端进行显示。所述相机高度Ch为显示终端展示地图的参考点高度，所述相机角度Fov为参考点的视场角，所述地图显示像素高度Mh为显示终端的显示宽度，以像素作为单位。上述三个特征数据在形式为2d和3d的地图中均可快速准确获取，参考终端以何种形式展示地图，其他显示终端都可依据所述特征数据得出统一的聚集结果，使不同显示终端的使用者可有效进行信息传达，避免信息偏差。另一方面，显示终端只需处理特征数据和待显示的经纬度点，无需对地图的所有经纬度点纳入聚集计算当中，大大减少了处理时间，提高渲染显示效率。
所述相机高度Ch、相机角度Fov和地图显示像素高度Mh构建虚拟像素空间具体为：所述虚拟像素空间一行包括的像素个数等于：360*地球半径/[tan(Fov/2)*Ch*2/Mh]；所述虚拟像素空间一列包括的像素个数等于：180*地球半径/[tan(Fov/2)*Ch*2/Mh]。三个特征数据影响虚拟像素空间的尺 寸大小，虚拟像素空间构成的像素越小，其单位像素可映射的经纬度点越多。其中的相机高度Ch与参考终端显示的地图缩放情况关联，地图越小，参考点高度越高，相机高度Ch的值则越大。以所述特征数据构建的虚拟像素空间可适应不同地图缩放情况，从而得出合理的聚集结果。另一方面，全地球的经纬度点均可映射至虚拟像素空间当中，意味着在同一地图缩放情况下，待显示的经纬度点若因平移操作发生了改变，重新进行聚集计算只需再次把经纬度点映射在相同的虚拟像素空间中，提高了平移操作时的渲染显示效率。
进一步地，对所述待聚集像素坐标进行聚集，形成聚集点的步骤具体为：预设聚集半径，所述聚集半径以像素作为单位；在全部待聚集像素坐标中选择一个作为中心点；将中心点、距离中心点小于所述聚集半径的待聚集像素坐标形成一个聚集点，所述聚集点的像素坐标与对应的中心点相同；在剩下没有形成聚集点的待聚集像素坐标中选择其中一个，作为另一个聚集点对应的中心点进行聚集；不断重复创建中心点后形成聚集点的过程直至所有待聚集像素坐标均形成聚集点。聚集半径以像素作为单位，相同的聚集半径包括的像素点是相同的，在不同尺寸的虚拟像素空间中，单个像素点代表的经纬度点数量不同，最后得出的聚集结果也不相同，单个像素点代表的经纬度点越多，落入一个中心点聚集半径的待聚集像素坐标数量越大。如此，聚集结果更为合理，当地图缩小时，使显示的聚集点(经纬度点)不致过密，当地图放大时，使显示的聚集点(经纬度点)不致太过稀疏。聚集半径为预设值，可根据聚集点要反映的地理信息对聚集半径可进行调整，更好地反映地图信息。
进一步地，将所述聚集点转换为相应的经纬度点供显示终端进行显示的步骤具体为：形成聚集点后计算聚集数，所述聚集数为形成聚集点的待聚集像素坐标的个数；将所述聚集点转换为相应的经纬度点，并将对应的聚集数发送至显示终端，供显示终端进行显示。
进一步地，所述的一种多显示终端图标数据显示方法还包括储存步骤和预判断步骤；所述储存步骤具体为：在形成聚集点后储存所述聚集点及其对应特征数据和待显示的经纬度点；所述预判断步骤具体为：在所有显 示终端中根据特征数据对待显示的经纬度点进行聚集前先进行判断，判断是否储存有对应特征数据和待显示的经纬度点的聚集点，是则将储存的聚集点转换成相应的经纬度点供显示终端进行显示；否则进行聚集计算。本申请的聚集计算依托与所述虚拟像素空间，全地球的经纬度点均可映射至虚拟像素空间，区别于现有技术的聚集计算需考虑显示终端的当前地图显示范围，本申请的虚拟像素空间可以包括同一地图缩放情况下全球的全部情况，平移操作不改变聚集计算的结果，利用此特点，可对每次聚集结果进行储存，供下次相同地图缩放情况下进行直接显示，提高显示效率。
进一步地，所述特征数据的相机高度Ch为有限集合。有限的相机高度Ch对应有限的地图缩放情况，减少需要储存的聚集计算的结果。
本申请的多显示终端图标数据显示系统包括：
选择模块，在多个显示终端中选择一个作为参考终端，并获取参考终端的特征数据；其中，所述特征数据包括参考终端的相机高度Ch、相机角度Fov和地图显示像素高度Mh；
发送模块，用于将所述特征数据和待显示的经纬度点发送至除参考终端的其他显示终端；
聚集模块，用于根据所述相机高度Ch、相机角度Fov和地图显示像素高度Mh构建虚拟像素空间并在所述虚拟像素空间中对所述待显示的经纬度点进行聚集计算；所述虚拟像素空间为由多个像素组成的区域，用于使经纬点坐标映射于其上，使经纬度点可用像素坐标进行表示；所述虚拟像素空间包含的像素个数与所述相机高度Ch成反相关。
更具体地，所述聚集模块构建虚拟像素空间的具体步骤为：接收所述相机高度Ch、相机角度Fov和地图显示像素高度Mh；构建一个x*y的虚拟像素空间；其中，x＝360*地球半径/[tan(Fov/2)*Ch*2/Mh]；y＝180*地球半径/[tan(Fov/2)*Ch*2/Mh]。
进一步地，所述多显示终端图标数据显示系统还包括储存模块，用于储存所述聚集模块聚集计算结果；所述聚集模块在进行聚集计算前先从所述储存模块上读取，若储存模块包含对应的聚集计算结果，聚集模块直接输出所述对应的聚集计算结果，否则进行聚集计算。
本申请的计算机存储介质，其上存储有计算机程序，所述计算机程序被程序执行主体执行时实现所述一种多显示终端图标数据显示方法。
与现有技术相比，本申请的有益效果为：保证多个显示终端的聚集结果相同，使不同显示终端的使用者可有效进行信息传达，避免信息偏差，2d、3d地图均适用；聚集过程快速，渲染显示效率高；允许对聚集效果进行储存，进一步提高显示效率。

具体实施方式
本申请附图仅用于示例性说明，不能理解为对本申请的限制。为了更好说明以下实施例，附图某些部件会有省略、放大或缩小，并不代表实际产品的尺寸；对于本领域技术人员来说，附图中某些公知结构及其说明可能省略是可以理解的。
实施例1
本实施例提供一种多显示终端图标数据显示方法，包括如下步骤：
在多个显示终端中选择一个作为参考终端，并获取参考终端的特征数据；其中，所述特征数据包括参考终端的相机高度Ch、相机角度Fov和地图显示像素高度Mh；将所述特征数据和待显示的经纬度点发送至除参考 终端的其他显示终端；在所有显示终端中根据特征数据对待显示的经纬点坐标进行聚集，具体步骤如下：根据所述相机高度Ch、相机角度Fov和地图显示像素高度Mh构建虚拟像素空间；所述虚拟像素空间为由多个像素组成的区域，其包含的像素个数与所述相机高度Ch成反相关；将待显示的经纬点坐标映射于所述虚拟像素空间上，得到多个待聚集像素坐标，并对所述待聚集像素坐标进行聚集，形成聚集点；将所述聚集点转换为相应的经纬度点供显示终端进行显示。
本实施例构建虚拟像素空间的具体方法为：利用所述特征数据决定虚拟像素空间的尺寸，所述虚拟像素空间一行包括的像素个数等于：360*地球半径/[tan(Fov/2)*Ch*2/Mh]；所述虚拟像素空间一列包括的像素个数等于：180*地球半径/[tan(Fov/2)*Ch*2/Mh]。本实施例以全球地图作为最大显示范围，在其他实施例中，若使用的地图地理范围较小，可适当缩小所述最大显示范围，即缩小虚拟像素空间可映射的最大经纬度点点集，其转换公式本领域技术人员可参考以上两式。
本实施例的聚集计算过程具体如下：预设聚集半径，所述聚集半径以像素作为单位；在全部待聚集像素坐标中选择一个作为中心点；将中心点、距离中心点小于所述聚集半径的待聚集像素坐标形成一个聚集点，所述聚集点的像素坐标与对应的中心点相同；在剩下没有形成聚集点的待聚集像素坐标中选择其中一个，作为另一个聚集点对应的中心点进行聚集；不断重复创建中心点后形成聚集点的过程直至所有待聚集像素坐标均形成聚集点。在其他实施例中，亦可使用其他常见的聚集方法或算法对所述待聚集像素坐标进行聚集。
本实施例中，形成聚集点后计算聚集数，所述聚集数为形成聚集点的待聚集像素坐标的个数；将所述聚集点转换为相应的经纬度点，并将对应的聚集数发送至显示终端，供显示终端进行显示。在其他实施例中，地图信息可不通过数字反映，诸如颜色、图案等均可替代。
如图1所示，本实施例最优选的一种实施方式如下：
S1：在多个显示终端中选择一个作为参考终端；
S2：获取参考终端的待显示的经纬点坐标、相机高度Ch、相机角度 Fov和地图显示像素高度Mh；
S3：根据所述相机高度Ch、相机角度Fov和地图显示像素高度Mh构建虚拟像素空间，所述虚拟像素空间一行包括的像素个数等于：360*地球半径/[tan(Fov/2)*Ch*2/Mh]；所述虚拟像素空间一列包括的像素个数等于：180*地球半径/[tan(Fov/2)*Ch*2/Mh]；
S4：将待显示的经纬点坐标映射于所述虚拟像素空间上，得到多个待聚集像素坐标；
S5：对所述待聚集像素坐标进行聚集，形成聚集点，所述形成聚集点的具体步骤为：
S51：在待聚集像素坐标中选择一个作为中心点；
S52：将中心点、距离中心点小于所述聚集半径的待聚集像素坐标形成一个聚集点；
S53：计算聚集数，所述聚集数为形成聚集点的待聚集像素坐标的个数；
S54：判断是否存在待聚集像素坐标；若是，重复依次进行S51、S52、S53、S54；若否，进行S55；
S55：发送聚集点对应的经纬度点及其聚集数；
S6：显示终端根据经纬度点和聚集数进行显示。
各个显示终端依照上述过程进行显示，无论参考终端使用的是3d形式的地图还是2d形式的地图，其他终端亦能快速准确识别特征数据，保证了聚集结果的统一。聚集半径以像素作为单位，相同的聚集半径包括的像素点是相同的，在不同尺寸的虚拟像素空间中，单个像素点代表的经纬度距离不同，最后得出的聚集结果也不相同，单个像素点代表的经纬度距离越大，落入一个中心点聚集半径的待聚集像素坐标数量越大。如此，聚集结果更为合理，当地图缩小时，使显示的聚集点(经纬度点)不致过密，当地图放大时，使显示的聚集点(经纬度点)不致太过稀疏。
实施例2
本实施例与实施例1的区别在于，还包括储存步骤和预判断步骤。
所述储存步骤具体为：在形成聚集点后储存所述聚集点及其对应特征数据和待显示的经纬度点。所述预判断步骤具体为：在所有显示终端中根 据特征数据对待显示的经纬度点进行聚集前先进行判断，判断是否储存有对应特征数据和待显示的经纬度点的聚集点，是则将储存的聚集点转换成相应的经纬度点供显示终端进行显示；否则进行聚集计算。
如图2所示，本实施例的一种优选实施方式具体如下：
A1：在多个显示终端中选择一个作为参考终端；
A2：获取参考终端的待显示的经纬点坐标、相机高度Ch、相机角度Fov和地图显示像素高度Mh；
A3：判断是否储存有对应待显示的经纬点坐标、相机高度Ch、相机角度Fov和地图显示像素高度Mh的聚集点，是则进行A3a，否则跳过A4、A5、A6进行A7；
A3a：根据所述相机高度Ch、相机角度Fov和地图显示像素高度Mh构建虚拟像素空间，所述虚拟像素空间一行包括的像素个数等于：360*地球半径/[tan(Fov/2)*Ch*2/Mh]；所述虚拟像素空间一列包括的像素个数等于：180*地球半径/[tan(Fov/2)*Ch*2/Mh]；
A4：将待显示的经纬点坐标映射于所述虚拟像素空间上，得到多个待聚集像素坐标；
A5：对所述待聚集像素坐标进行聚集，形成聚集点；
A6：储存所述聚集点；
A7：将所述聚集点转换为相应的经纬度点；
A8：显示终端根据经纬度点进行显示。
全地球的经纬度点均可映射至虚拟像素空间当中，经过多次聚集计算后，每个特征数据下的虚拟像素空间的聚集结果得到补充，平移操作可在显示终端上快速显示，渲染时间短，响应快速，下次显示相同特征数据的效率可从储存的聚集结果中快速读取。

本实施例的聚集模块3构建虚拟像素空间的具体步骤为：接收所述相机高度Ch、相机角度Fov和地图显示像素高度Mh；构建一个x*y的虚拟像素空间；其中，x＝360*地球半径/[tan(Fov/2)*Ch*2/Mh]；y＝180*地球半径/[tan(Fov/2)*Ch*2/Mh]。
本实施例的系统优选地包括储存模块4，用于储存所述聚集模块3聚集计算结果；所述聚集模块3在进行聚集计算前先从所述储存模块4上读取，若储存模块4包含对应的聚集计算结果，聚集模块3直接输出所述对应的聚集计算结果，否则进行聚集计算。
