图1是本说明书一示例性实施例示出的一种基于地理位置的POI检索方法的流程示意图。
所述基于地理位置的POI检索方法可以应用在检索服务提供商部署的检索平台中,所述检索平台的物理载体通常是服务器或者服务器集群。
请参考图1,所述基于地理位置的POI检索方法可以包括以下步骤:
步骤102,在检索不规则目标地理区域中的POI时,为所述目标地理区域生成指定形状的外接地理区域。
在本实施例中,用户可通过地图类软件进行POI检索,用户也可以通过具有基于地理位置进行检索功能的其他非地图类APP(Application,应用软件)进行POI检索,本说明书对此不作特殊限制。
在本实施例中,用户发起的检索请求中通常包括有POI类别和目标地理区域。
其中,所述POI类别通常由用户指定,是用户想要检索的实体的类别,例如,医院、银行、餐馆、酒店等。当然,用户在触发检索请求时,也可以不指定POI类别,那么可默认检索所有类别的POI,本说明书对此不作特殊限制。
所述目标地理区域的指定方式是多种多样的。
在一个例子中,用户可以在电子地图中手工绘制所述目标地理区域,例如,用户可以用手指或触摸笔绘制所述目标地理区域。
在另一个例子中,用户也可以通过文字指定所述目标地理区域,例如,输入所述目标地理区域对应的名称,诸如“奥林匹克公园”、“西湖文化广场”、“颐和园”等。
当然,用户也可以通过其他方式指定所述目标地理区域,本说明书对此不作特殊限制。
在本实施例中,针对用户触发的检索请求,可以获取其对应的目标地理区域,例如,获取该目标地理区域对应的位置坐标所组成的位置坐标序列。
当所述目标地理区域由用户手工绘制时,所述目标地理区域对应的位置坐标序列可以为用户在电子地图中绘制的多边形的顶点坐标。
当所述目标地理区域由用户通过文字指定时,所述目标地理区域对应的位置坐标序列通常是工作人员预先在线下采集并上传的,例如,工作人员实地采集并上传目标地理区域所组成的多边形的顶点坐标等。
当然,所述目标地理区域对应的位置坐标序列并不限制为目标地理区域所组成的多边形的顶点坐标,还可包括目标地理区域内其他位置点的坐标,本说明书对此不作特殊限制。
在本实施例中,当目标地理区域的形状是矩形、圆形等规则形状时,可以根据相关技术中提供的检索方式进行POI的检索。
当目标地理区域的形状为不规则多边形时,为了为用户检索到准确的POI,可以生成所述目标地理区域对应的外接地理区域。
其中,所述外接地理区域的形状可以由开发人员预先进行设置,例如,矩形、圆形等规则图形。
在本实施例中,以所述外接地理区域的形状是矩形为例,可以根据目标地理区域所对应的多边形的顶点坐标分别确定矩形的左上、左下、右上、右下4个顶点的顶点坐标,然后根据所述顶点坐标确定所述外接地理区域。
举例来说,请参考图2,假设检索请求中指定的目标地理区域对应图2所示的不规则五边形ABCDE,则在本步骤中,可根据不规则五边形ABCDE的五个顶点:点A、点B、点C、点D和点E这五个顶点的位置坐标确定其矩形的外接地理区域APQR的四个顶点:点A、点P、点Q和点R的位置坐标,然后可根据这四个顶点的位置坐标确定目标地理区域不规则五边形ABCDE的外接地理区域矩形APQR(图2中虚线所示的矩形)。
步骤104,在所述外接地理区域内检索所述POI。
基于前述步骤102,在生成目标地理区域的外接地理区域后,可以在该外接地理区域内为用户检索所述检索请求对应的POI。这部分的处理与实现可以参考相关技术,本说明书对此不作特殊限制。
步骤106,针对检索到的POI,判断所述POI是否在所述目标地理区域内。
在本实施例中,针对在外接地理区域内检索到的POI,可以依次判断所述POI是否在所述目标地理区域内。
具体而言,针对某个POI,可以将该POI看作一个点,例如,根据该POI的位置坐标,将该POI看作是电子地图中的一个点。然后,可根据射线法判断这个点是否在目标地理区域对应的多边形内部。
在采用射线法进行判断时,可以以POI对应的点为端点做任意射线,然后获取该射线与目标地理区域对应的多边形的交点数量。
若交点数量是奇数,则可以确定该点在在目标地理区域对应的多边形内部,进而可确认对应的POI在目标地理区域的内部。
若交点数量是偶数,则可以确定该点在在目标地理区域对应的多边形外部,进而可确认对应的POI在目标地理区域的外部。
请参考图3,假设X、Y是在外接地理区域APQR内检索到的POI。
针对X,可以以X为端点,向N方向做射线XN,射线XN与目标地理区域ABCDE仅有1个交点,因此可以确认X位于目标地理区域内部。
针对Y,可以以Y为端点,向M方向做射线YM,射线YM与目标地理区域ABCDE有2个交点,因此可以确认Y位于目标地理区域外部。
当然,在实际应用中,还可以采用其他方式判断检索到的POI是否在目标地理区域内部,本说明书对此不作特殊限制。
步骤108,若所述POI在所述目标地理区域内,则将所述POI确定为检索结果。
基于前述步骤106的判断结果,当外接地理区域内检索到的POI在目标地理区域内时,可以将该POI确定为检索结果,进而返回给用户。
当外接地理区域内检索到的POI在目标地理区域外时,说明该POI不符合用户的检索需求,无需将该POI确定为检索结果,进而无需将该POI返回给用户。
至此,本实施例可实现不规则形状的目标地理区域内POI的检索,且检索到的POI均位于目标地理区域内,不存在干扰POI,准确率较高。
此外,当用户对检索到的POI进行排序、筛选时,由于不存在干扰POI,可大大降低排序、筛选的耗时,提高排序、筛选的效率。
由以上描述可以看出,本说明书可以在检索不规则目标地理区域中的POI时,为该目标地理区域生成外接地理区域,并在外接地理区域内进行POI检索,然后再根据目标地理区域对检索结果进行过滤,从而在不规则形状的目标地理区域内实现精准的POI检索,提升用户的检索体验。
