其中,所述第一区域集合包含有一个或多个机器人可通行区域,所述第二区域集合内包含有一个或多个禁止机器人通行区域。而所述可通行区域可以为平坦路面,也可以为机器人能过躲避的障碍,而禁止通行区域则可以为墙壁、家具等障碍物等,本申请实施例对此不做具体限定。
在本公开实施例中,本步骤可以为根据接收到的地图数据解析地图中包含的各个元素所对应的几何特征、地图内各元素属性等确定某一区域属于第一区域集合还是第二区域集合,而在各个区域集合内可以配置有与各个区域分别对应的区域标识信息,如在第一区域集合内可以包括客厅、主卧、1号展厅等区域标识信息,用来标识机器人在与集合内标识信息对应的区域可以通行,而在第二区域集合内可以包括如1号家具、2号墙壁、楼梯等区域标识信息,用来标识移动机器人在这些标识信息所对应的区域内无法通行需要躲避,并且在进行三维地图展示时可以根据标识信息分别配置相应的显示高度。
103、利用预置高度算法确定与所述第二区域集合内各个区域分别对应的显示高度。
具体地,本步骤中所述的预置高度算法可以为根据各个区域的面积确定的,也可以为结合当前机器人作业区整体面积所确定的,还可以是结合当前机器人作业区中各分区的面积大小确定的,即如当前机器人作业区被中存在2个可通行区域和3个禁止通行区域,在确定这3个禁止通行区域的显示高度时便可根据这5个分区的面积大小和/或面积比例等确定第二区域集合内各个区域的显示高度,但不限于此。
需要说明的是,现有的三维地图显示方案中,无论当前地图标识的实际面积多大,在三维地图显示时地图内墙壁等障碍物的显示高度都是一定的,如对于某家庭室内地图中的第二区域集合内存在有室内支撑墙壁,该墙壁实际尺寸为长度10米,宽度0.5米,高度为3.5米,第二区域集合中 还存在有一垃圾桶,该垃圾桶的实际尺寸为长度0.3米、宽度0.1米、高度为0.5米,当使用相同的显示高度1米显示该支撑墙壁和垃圾桶时,那么在家庭室内三维地图中垃圾桶显示体会遮挡其他区域,而支撑墙壁的立体显示效果却不够明显。但通过本申请实施例,按照一定算法能够配置不同区域对应不同的显示高度进行显示,如上述家庭室内地图可以按照墙壁显示高度为3米进行显示,垃圾桶显示高度按照0.4米进行显示,从而达到改善三维地图显示效果的目的。
104、按照所述显示高度在三维地图中对所述作业区进行展示。
其中,显示高度可以为地图中对应的尺寸值,也可以实际尺寸,当显示高度标识的数值为实际尺寸时,可以按照地图比例关系进行换算并根据得到的换算结果在三维地图中进行展示。
在本申请中当各个区域的显示高度确定之后,按照所确定的显示高度值配置三维地图进行展示即可,而具体的显示方法可以为现有技术中三维地图的显示方法,本申请实施例对此不再赘述。
本公开提供了一种三维地图显示的优化方法及装置、存储介质、终端,与现有技术相比,本公开实施例通过获取作业区的地图数据;解析所述地图数据得到第一区域集合和第二区域集合,所述第一区域集合包含有一个或多个机器人可通行区域,所述第二区域集合内包含有一个或多个禁止机器人通行区域;利用预置高度算法确定与所述第二区域集合内各个区域分别对应的显示高度;按照所述显示高度在三维地图中对所述作业区进行展示,实现按照一定的高度计算方法确定地图中禁止通行各区域分别对应的显示高度,并根据配置的相应的显示高度在三维地图中进行展示,避免了按照唯一确定显示高度对所有禁止通行区域进行展示造成的三维地图显示效果较差的问题,从而改善了三维地图显示效果。
进一步的,作为上述实施例具体实施方式的细化和扩展,为了完整说明本实施例的具体实施过程,提供了另一种三维地图显示的优化方法,如图2所示,该方法包括:
201、获取作业区的地图数据。
其中,所述地图数据为移动机器人在作业区内采集并绘制的。
需要说明的是,现有移动机器人能够根据自身佩戴的传感器或激光测距仪等扫描采集外部环境数据,并从中抽取几个特征生成用来表示外部环境的地图数据,而该地图数据即可以存储在机器人内以供机器人作业期间根据地图数据进行作业和自主避障等,该地图数据还可以上传至服务器或移动终端设备,以供用户使用和查看机器人作业区域等。
202、解析所述地图数据得到第一区域集合和第二区域集合。
其中,所述第一区域集合包含有一个或多个机器人可通行区域,所述第二区域集合内包含有一个或多个禁止机器人通行区域。具体地,本步骤中所述的概念解释和具体实施方式可以参考步骤202中相应描述,本申请实施例在此不再赘述。
203、当接收到三维地图显示指令时,输出用于供用户选择显示模式的选择请求。
其中,所述显示模式包含有第一显示模式,也可以包含有第二模式,其中,第一显示模式为基于作业区整体面积确定所述显示高度,第二显示模式为基于作业区内各个区域面积确定所述显示高度。具体地,在第一显示模式中只需要根据当前作业区域总占地面积确认一个显示高度值即可,并利用该显示高度值对第二区域集合内的各个区域的显示高度进行配置,而在第二显示模式下需要根据第二区域集合内各个区域的面积分别确定相应的显示高度。显然,基于第一模式的地图显示中相比较于第二模式,其数据处理量更少,显示效率更高,但其显示效果略差。因此,在本申请实施例中通过提供不同的显示模式,以便于用户根据自身需求进行选择,从而可以在保证三维地图显示效果的同时提升用户使用感受。
而所述三维地图显示指令可以为用户通过触摸显示屏发送的,如点击地图中的“3D显示”图标,或者用户通过预设手势操作触摸显示屏等,此时便可以触发向移动机器人发送三维地图显示指令,以使得移动机器人在接收到地图显示指令后,输出本步骤中的选择请求。具体地,该选择请求可以以窗口形式或者文字等形式进行输出,当用户通过触摸屏选择后将响应数据返回,但不限于此。
204a、当接收到与所述第二显示模式对应的响应数据时,获取与所述第二区域集合内各个区域分别对应的区域面积。
其中,所述区域面积为所述区域在平面地图中的占地面积。而本步骤中所述的各个区域在平面地图中对应的区域面积可以为根据获取到的地图数据进行计算得到的,而计算得到的面积值可以为实际面积也可以为在地图中所占的尺寸,本申请实施例对此不做具体限定。
205a、根据所述区域面积确定与各个区域分别对应的显示高度。
其中,显示高度可以为地图中对应的尺寸值,也可以实际尺寸,当显示高度标识的数值为实际尺寸时,可以按照地图绘制比例关系进行换算并根据得到的换算结果在三维地图中进行展示。
对于本申请实施例,所述步骤205a包括:根据所述区域面积所对应的面积区间,以及面积区间与显示高度之间的第一映射关系,确定与各个区域分别对应的显示高度;或,将所述各个区域面积与第一预设系数的乘积确定为各个区域的显示高度。
本步骤中的显示高度可以为按照面积区间进行划分,也可以为针对每个区间面积分别计算。当显示高度确认方式为区间映射时,首先判断待确定显示高度的区间面积所属的区间,而后根据该区间和映射关系得到该待确定显示高度的区间所对应的显示高度。而第一预设系数可以为根据不同的应用场景进行设定,以使得区域面积在于该系数相乘得到显示高度时,确保显示高度和区面积正相关即可,即区域面积越大时在三维地图中的显示高度值越大,区域面积越小时在三维地图中的显示高度值越小。
在本申请实施例中,无论通过上述的哪一种显示高度计算方式,都能够实现根据区域面积确定与其对应的显示高度,以使得在一定程度上显示高度和区域面积成正比,即区域越大时对应的显示高度越高,而区域越小时对应的显示高度越低,而由于显示高度大时其区域面积也大所以在进行三维显示时并不会遮挡其他区域,因此能够在保证立体显示效果的同时避免不同区域之间的遮挡问题,确保了三维地图显示效果。
与所述步骤204a并列的步骤204b、当接收到与所述第一显示模式对应的响应数据时,获取作业区面积。
根据上述步骤203中描述可知,第一显示模式是将机器人当前作业区整体面积进行确定的,所以当接收到用户选择第一显示模式的响应数据时, 则获取机器人当前作业区的整体区域面积,以便于根据该整体面积确定作业区的第二区域集合内的各个区域的显示高度。
205b、根据所述作业区面积并利用预置高度算法确定与所述第二区域集合内各个区域对应的唯一显示高度。
在申请实施例中提供的另一种第二区域集合内各个区域的显示高度算法中,因为是根据作业区整体面积确定的,所以根据该作业区面积和一定算法即可计算得到整个作业区内的禁止通行区域的显示高度,并且各个禁止通行区域的显示高度是相同的。
对于本申请实施例,所述步骤205b包括:根据所述作业区面积所对应的面积区间,以及面积区间与显示高度之间的第二映射关系,确定与所述第二区域集合内各个区域对应的唯一显示高度;或,
将所述作业区面积与第二预设系数的乘积确定为与所述第二区域集合内各个区域对应的唯一显示高度。
具体地,本步骤中各个区域对应的唯一显示高度可以按照当前作业区面积所属的面积区间映射得到的,也可以根据作业区总面积计算得到的。当显示高度确认方式为区间映射时,首先判断作业区面积所属的区间,而后根据该区间和映射关系得到该作业区的第二区域集合内的各个区域所对应的显示高度,该第二区域集合内各个区域对应的显示高度是相同的。而第二预设系数可以为根据不同的应用场景进行设定,以使得作业区面积与该系数相乘后得到显示高度时,确保显示高度和作业区面积正相关即可,即作业区面积越大时作业区内的禁止通行区域在三维地图中的显示高度值越大,作业区域面积越小时作业区内的禁止通行区域在三维地图中的显示高度值越小
206、检测所述显示高度是否在预设高度阈值范围内。
其中,所述预设高度阈值可以为根据具体应用场景进行设定,如根据不同的区域面积设定相应的极限值,也可以为结合使用经验确定本步骤中所述的预设高度阈值,本申请实施例对此不做具体限定。
207、当所述显示高度不在所述预设高度阈值范围内时,根据所述预设高度阈值范围的临界值确定当前区域的显示高度。
具体地,当计算得到的显示高度小于预设阈值范围的最小值时,则将预设阈值范围的最小值确定为当前的显示高度;而当计算所得显示高度大于预设阈值范围的最大值时,则将预设阈值范围的最大值确定为当前的显示高度。
在本申请实施例,通过设定预设高度阈值并在检测到计算所得的显示高度不在预设高度区间内将其进行修正,避免了根据区域面积计算确定禁止通行区域显示高度时,由于计算所得显示高度值过大或者过小导致的显示效果较差的问题,从而进一步改善了三维地图显示的效果。
