Description
本申请要求在2014年4月28日提交中国专利局、申请号为201410175338.0、发明名称为“一种电子地图绘制区域确定方法、装置及导航设备”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。
本发明涉及电子地图处理技术领域,尤其涉及一种电子地图绘制区域确定方法、装置及导航设备。
目前,在导航设备的显示界面显示电子地图区域的大小与导航设备的分辨率有关,对于尺寸大小相同的导航设备而言,显示同一电子地图时,分辨率高的导航设备显示的电子地图包含的区域较广,而分辨率低的导航设备显示的电子地图包含的区域较窄,如图1所示,中间阴影部分为电子地图的显示区域。
若用户需要调整显示界面显示的电子地图包含的区域大小,需要手动调整参数来控制当前显示界面显示的电子地图所包含的区域范围。
由于不同硬件设备的尺寸和分辨率均不一致,一方面,对于分辨率高的导航设备,显示界面显示的电子地图包含的区域范围比较广,需要加载的地图数据量比较多,这样,渲染引擎需要加载的地图数据量非常大,影响了渲染的速度;另一方面,对于分辨率低的导航设备,显示界面显示的电子地图包含的区域范围较窄,虽然渲染引擎需要加载的地图数据量较少,但是显示的区域范围可能无法满足用户的查看需求。
因此可见,如何在不同尺寸、不同分辨率的导航设备上显示合理的电子地图包含的区域范围成为现有技术中亟待解决的问题。
发明内容

在绘制电子地图时,获取导航设备的实际屏幕显示参数;
根据所述实际屏幕显示参数和预置的标准屏幕显示参数,确定电子地图区域绘制比例参数;
根据确定出的电子地图区域绘制比例参数确定电子地图绘制区域。
本发明实施例提供一种电子地图绘制区域确定装置,包括:

本发明实施例提供一种导航设备,包括上述的电子地图绘制区域确定装置。
本发明实施例提供的电子地图绘制区域确定方法、装置及导航设备,在绘制电子地图时,首先获取导航设备的实际屏幕显示参数,根据获取的导航设备的实际屏幕显示参数和预置的标准屏幕显示参数,确定电子地图区域绘制比例参数,并根据确定出的电子地图区域绘制比例参数确定电子地图绘制区域,上述过程中,在确定电子地图区域绘制比例参数时,参考了导航设备的实际屏幕显示参数,使得根据电子地图绘制参数确定出的电子地图绘制更加符合导航设备屏幕显示,从而能够在导航设备屏幕上显示合理的电子地图包含的区域范围。
本发明的其它特征和优点将在随后的说明书中阐述,并且,部分地从说明书中变得显而易见,或者通过实施本发明而了解。本发明的目的和其他优
点可通过在所写的说明书、权利要求书、以及附图中所特别指出的结构来实现和获得。
此处所说明的附图用来提供对本发明的进一步理解,构成本发明的一部分,本发明的示意性实施例及其说明用于解释本发明,并不构成对本发明的不当限定。在附图中:
图1为现有技术中,同一电子地图在不同分辨率的导航设备上显示的对比示意图;
图2为本发明实施例中,电子地图绘制区域确定方法的实施流程示意图;
图3为本发明实施例中,电子地图绘制区域确定装置的结构示意图。
为了实现在导航设备屏幕上显示合理的电子地图区域范围的目的,本发明实施例提供了一种电子地图绘制区域确定方法、装置及导航设备。
以下结合说明书附图对本发明的优选实施例进行说明,应当理解,此处所描述的优选实施例仅用于说明和解释本发明,并不用于限定本发明,并且在不冲突的情况下,本发明中的实施例及实施例中的特征可以相互组合。
如图2所示,为本发明实施例提供的电子地图绘制区域确定方法的实施流程示意图,可以包括以下步骤:
S21、在绘制电子地图时,获取导航设备的实际屏幕显示参数;
本发明实施例中,电子地图引擎可以提供一个UI(用户界面)层回传设备参数信息接口:MEK_GRA_SetBaseMapRate,用于接收导航设备的尺寸、屏幕显示分辨率等屏幕显示参数。这样,在需要绘制电子地图时,可以通过该接口获取导航设备的实际屏幕显示参数。
S22、根据获取的实际屏幕显示参数和预置的标准屏幕显示参数,确定电子地图区域绘制比例参数;
具体实施时,需要预先设置标准屏幕显示参数,可以但不限于包括标准
屏幕显示分辨率和标准屏幕尺寸。假设预置的标准屏幕显示分辨率(PPI)为Ps1*Ps2,标准屏幕尺寸为Cs,其中Ps1为标准屏幕显示分辨率中的长像素值,Ps2为标准屏幕显示分辨率中的宽像素值。
基于标准屏幕尺寸和标准屏幕显示分辨率,可以确定出标准屏幕每英寸像素密度(DPI),以下以Ds表示标准屏幕每英寸像素密度。较佳的,本发明实施例中,可以按照以下公式确定标准屏幕每英寸像素密度:以标准屏幕显示分辨率为800*480,标准屏幕尺寸为13寸为例,对应的标准屏幕每英寸像素密度(Ds)则为72。
相应的,本发明实施例中,基于导航设备的实际屏幕尺寸和实际屏幕显示分辨率,可以确定出实际屏幕每英寸像素密度(Dt)。较佳的,本发明实施例中,可以按照以下公式确定实际屏幕每英寸像素密度:其中实际屏幕显示分辨率(PPI)为Pt1*Pt2,实际屏幕尺寸为Ct,其中Pt1为实际屏幕显示分辨率中的长像素值,Pt2为实际屏幕显示分辨率中的宽像素值。
这样,步骤S22中,基于确定出的实际屏幕每英寸像素密度和标准屏幕每英寸像素密度以及实际屏幕尺寸和标准屏幕尺寸,可以按照如下公式确定电子地图区域绘制比例参数:其中:f表示电子地图区域绘制比例参数;Dt表示实际屏幕每英寸像素密度;Ds表示标准屏幕每英寸像素密度;Ct表示实际屏幕尺寸;Cs表示标准屏幕尺寸。
S23、根据确定出的电子地图区域绘制比例参数确定电子地图绘制区域。
较佳的,设定标准屏幕1像素表示的预置的标准区域为l,为保证实际屏幕与标准屏幕显示的区域相近,则实际屏幕1像素表示的区域为其中,l'表示实际屏幕每像素表示的区域;l表示标准屏幕每像素预置的标准区域;f表示电子地图区域绘制比例参数。例如,以预置l为100米的区域、f=2为例,
本发明实施例中,在确定电子地图绘制区域时,需要用2个像素绘制100米的区域,即本发明实施例中,使用2个像素绘制标准设备1个像素表示的区域。由此,步骤S23中,可以根据以下公式确定电子地图绘制区域:其中:F表示实际绘制区域;l表示标准屏幕每像素预置的标准区域;f表示电子地图区域绘制比例参数,Pt1表示实际屏幕显示分辨率中的长像素值。
在确定出了电子地图绘制区域之后,电子地图引擎便可以根据确定出的绘制区域绘制电子地图。
为了更好的理解本发明,以下以两部导航设备为例对本发明实施例进行说明,需要说明的是,本发明涉及的导航设备可以为专门导航仪,也可以是安装有电子地图的终端设备等,本发明对此不做限定。为了便于描述,以标准屏幕显示分辨率设置为800*480,标准屏幕尺寸设置为13寸为例,从而,根据步骤S22中提供的公式能够确定出标准屏幕每英寸像素密度为72,且预置的标准绘制区域为1像素绘制100米,那么800像素可以绘制800*100=80KM。
假设第一部导航设备的实际屏幕显示分辨率为960*640,实际屏幕尺寸为3.5寸,则可以确定实际屏幕每英寸像素密度为330;假设第二部导航设备的实际屏幕显示分辨率为1136*640,实际屏幕尺寸为4寸,则可以确定实际屏幕每英寸像素密度为326。
则根据步骤S23可以确定,第一部导航设备的电子地图绘制区域为:第二部导航设备的电子地图绘制区域为:与标准设备能够绘制80KM的区域也基本一致。也就是说,本发明实施例中,
不同屏幕尺寸和屏幕显示分辨率的导航设备上显示的电子地图所包含的范围基本一致。
由此可见,根据本发明实施例提供的电子地图绘制区域确定方法确定出的电子地图绘制区域基本相同,在不同屏幕尺寸和屏幕显示分辨率的导航设备上能够显示区域基本相同的电子地图。
本发明实施例中,由于参考了导航设备的实际屏幕显示参数,使得根据电子地图绘制参数确定出的电子地图绘制更加符合导航设备屏幕显示,从而能够在导航设备屏幕上显示合理的电子地图包含的区域范围。同时,无需用户手动调整绘制参数,电子地图引擎可以根据获取的导航设备的屏幕尺寸和屏幕显示分辨率确定电子地图绘制区域,从而提高了电子地图的绘制效率。
基于同一发明构思,本发明实施例中还提供了一种电子地图绘制区域确定装置及导航设备,由于上述装置及设备解决问题的原理与电子地图绘制区域确定方法相似,因此上述装置及设备的实施可以参见方法的实施,重复之处不再赘述。
如图3所示,为本发明实施例提供的电子地图绘制区域确定装置的结构示意图,可以包括:
获取单元31,用于在绘制电子地图时,获取导航设备的实际屏幕显示参数;
确定单元32,用于根据获取单元31获取的实际屏幕显示参数和预置的标准屏幕显示参数,确定电子地图区域绘制比例参数;
