在目标空间中对目标物体进行定位的方法及测距装置 技术领域
本发明涉及测绘领域，具体地，本发明涉及一种借助于测距装置在目标空间中对目标物体进行定位、一种借助于测距装置在目标空间中搜索定位点的方法以及使用上述方法进行目标物体定位的测距装置。
背景技术
测距仪是一种广受欢迎并且接受度很高的测量空间距离的便携式设备，然而，现有的测距仪仅仅被用于测量至某一个反射平面的直线距离，而不能实现目标物体的空间布局，而实现物体的空间布局必然需要同时实现对空间距离的测量以及该目标物体在相应的空间中的目标位置的定位。
在申请号为WO2014/124785的PCT申请之中公开了一种测距和定位系统，在该专利申请之中公开了一种包括发射器和接收器节点的测距和定位系统。在该专利申请之中，该测距和定位系统具有测距模式，在该测距模式中在主设备和从设备之间进行信号的测距交换，也就是说，在该专利申请中距离的测定是通过对于主从设备之间的信号的评估来实现的。
此外，专利申请CN 104121885 A公开了一种定位测距仪，在该定位测距仪中具有可旋转的红色激光定位杆I、红色激光定位杆II以及线性角位移传感器I、角位移传感器II。该专利申请通过激光灯定位并且利用角位移测出角度，再由两个角位移轴心距算出要测的两点距离。即定位原理是采用角位移传感器和激光灯来实现的。
由上述专利申请的描述可知，现有技术中的测距以及定位方法要么通过主从设备间的复杂的信号分析来实现，要么通过结构复杂的包含激光定位杆和角位移传感器的定位测距仪来实现。以上两种方式均是成本高昂的，而且操作复杂不便于实施。

本发明的其它特征、特点、优点和益处通过以下结合附图的详细描述将变得更加显而易见。
具体实施方式
在以下优选的实施例的具体描述中，将参考构成本发明一部分的所附的附图。所附的附图通过示例的方式示出了能够实现本发明的特定的实施例。示例的实施例并不旨在穷尽根据本发明的所有实施例。可以理解，在不偏离本发明的范围的前提下，可以利用其他实施例，也可以进行结构性或者逻辑性的修改。因此，以下的具体描述并非限制性的，且本发明的范围由所附的权利要求所限定。
图1示出了依据本发明所提出的测距装置的方框示意图100。从图中可以看出，该测距装置100包括尺寸参数获取模块110，该尺寸参数获取模块110被构造用于获取目标空间在第一维度上的第一尺寸参数以及目标物体在第一维度上的第二尺寸参数。此外，该测距装置100还包括分析模块120，该分析模块120被构造用于根据第一尺寸参数、第二尺寸参数和第一预定规则确定第一布局指示，所述第一布局指示包含关于目标物体在目标空间中的第一维度上的第一目标位置的信息。
在此，本领域的技术人员应当了解，第一尺寸参数和所述第二尺寸参数包括但不限于长度数据、高度数据和/或角度数据；目标物体既能够是规则物体，例如为方形桌子的长方体，也能够是诸如圆形或者其他不规则形态；相对应地，目标空间既能够是诸如规则的方形房间，也能够是诸如圆形或者椭圆形等不规则形状的房间。
依据本发明所提出的测距装置既能够实现对于目标空间和目标物体的尺寸上的测量，也能够基于所述第一尺寸参数、所述第二尺寸参数和第一 预定规则实现目标位置的计算，进而能够为便捷地将所述目标物体摆放在所述目标空间的目标位置提供依据。
除此之外，依据本发明的测距装置100还能够包括提示模块(图中未示出)，该提示模块被构造用于当目标物体处于在目标空间中的第一维度上的第一目标位置时根据第一布局指示输出提示信号。例如，当测距装置100的分析模块120所得到的第一布局指示表示将物体的一面放置在距离墙面1米处时，当测距装置识别出该物体的这一面距离墙面距离为1米时便会输出提醒信号，以便提示该物体已经处于第一目标位置了。
而对于如何输出该提示信号，方式则是多种多样的，例如通过显示装置输出光学提示、通过扬声器输出声学提示和/或通过数据接口输出至与之连接的提示设备的提醒信号。也就是说，例如当测距装置100的分析模块120所得到的第一布局指示表示将物体的一面放置在距离墙面1米处时，当测距装置识别出该物体的这一面距离墙面距离为1米时既能够通过例如测距装置自身所装备有的蜂鸣器发出声音，也能够通过测距装置自身所装备有的显示屏或者提示灯输出光学信号，当然也能够通过测距装置的通信接口例如通过蓝牙接口或者WiFi接口将该提示信号输出至诸如手机的便携式手持设备，以便更好地输出提示信号。
在本发明中，所提及的测距装置还包括存储模块，该存储模块被构造用于存储第一预定规则；和/或该测距装置能够包括通信模块，该通信模块被构造用于接收第一预定规则。此处的第一预定规则例如能够是将目标物体在第一维度上布置在目标空间中的等分点处。此时等分点能够有多种表现形式，例如将目标物体在第一维度上居中布置在目标空间中；或者将目标物体在第一维度上布置在目标空间中的1/3、2/3、1/4、3/4、1/5、2/5等分点处。如前所述，此处所说的等分点并不局限于长度等分点或高度等分点，也能够是其他形式的等分点，例如角度等分点等。
在本发明的一种优选的实施形式之中，尺寸参数获取模块120既能够包括测距仪，其中，测距仪被构造用于获取目标空间在第一维度上的第一尺寸参数；也能够包括测距轮，该测距轮被构造用于获取目标物体在第一维度上的第二尺寸参数。此时的测距装置集测距仪和测距轮为一体，能够以更加便捷的方式或者空间距离和物体长度。例如，当需要将一张桌子布置在一个房间中时，该测距装置既能够借助于所包括的测距仪方便地获取 房间的长宽高度，也能够借助于所包括的测距轮方便地获取桌子的长宽高数据，由此能够进一步简化后续的目标物体在目标空间中的摆放。
在本发明的一种优选的实施形式之中，测距仪还被构造用于获取目标空间在第二维度上的第三尺寸参数和/或目标空间在第三维度上的第四尺寸参数。以这样的方式，该测距装置能够实现将目标物体布置在二维的平面或三维的空间之中的预定位置处。其中，第一维度、第二维度和/或第三维度相互垂直。
综上所述，借助于依据本发明所提出的测距装置能够实现目标物体在目标空间中的期望的定位，例如居中放置或者放置在三分之一等分点处，进而实现在目标空间中的物体摆放以及布局。
图2示出了依据本发明所提出的借助于测距装置在目标空间中对目标物体进行定位的方法的流程示意图200。从图中可以看出，该方法包括以下步骤：
首先，在第一个步骤210之中，获取所述目标空间在第一维度上的第一尺寸参数；
然后，接下来在第二个步骤220之中，获取目标物体在第一维度上的第二尺寸参数；
最后，在第三个步骤230中，根据第一尺寸参数、第二尺寸参数和第一预定规则确定第一布局指示，所述第一布局指示包含关于目标物体在目标空间中的第一维度上的第一目标位置的信息。
在此，第一预定规则既能够被存储在测距装置的存储器之中，也能够由测距装置通过其通信模块来从外部接收。也就是说，该第一预定规则能够是预定义在测距装置之中并且存储在测距装置的存储器之中的，这种实现方式不需要借助于其他外部设备的配合便能够独立地实现所述第一预定规则的读取，使用起来较为方便；当然，该第一预定规则也能够是测距装置通过其通信模块接收的，这样的实现方式能够使得测距装置得以动态配置，从而使得目标物体在目标空间中的定位更为灵活。
在本发明的一种优选的实施例中，该方法还包括根据第一布局指示，当所述目标物体处于在目标空间中的第一维度上的第一目标位置时由测距装置输出提示信号。
图3示出了依据本发明所提出的借助于测距装置在目标空间中搜索定 位点的方法的流程示意图300。从图中可以看出，该借助于测距装置在目标空间中搜索定位点的方法包括以下步骤：
首先，在步骤310中，测距装置接收预定规则，该预定规则指示定位点与参考点之间的相对位置；以及
接下来，在步骤320中，测距装置根据所接收的预定规则来搜索定位点并输出提示信号。
举例来说，例如用户希望在一面4米宽的墙上居中开一个2米宽的窗户，则预定规则例如能够是找出离墙角的参考点1米和3米的两个定位点，此时无论是将测距装置放置在参考点处还是放置在待寻找的定位点处，只要满足了上述的预订规则，测距装置便会输出提示信号，该提示信号的输出方式在前面已经描述过了，在此不再赘述。
接下来将借助于图4至图7来描述借助于前述的测距装置以及定位方法在目标空间中对目标物体实施定位的第一至第四实施例。
图4示出了借助于前述的测距装置以及定位方法在目标空间中对目标物体实施定位的第一实施例的过程示意图400。从图中可以看出，为了将物体401布置在空间402的图示横向上的居中处，首先需要借助于测距装置100测量空间402在图示横向上的距离d401，然后，需要借助于测距装置100测量待放置的物体401在图示横向上的距离d402，本领域的技术人员应当了解，此处的距离d401及d402均已包括测距装置本身的尺寸。由于目标是将物体401布置在空间402的图示横向上的居中处，所以只要使得物体401和空间402图示横向上的边之间的距离d403为(d401-d402)/2便能满足要求了。此时，既能够将测距装置100靠在墙边上，判断测距装置100离物体401的距离是否满足要求；也能够将测距装置100放置在物体401离墙边更近的边上使得测距装置100随着物体401一起从虚线位置移动至实线位置，判断测距装置100离物体401的距离是否满足要求即可。在所测的距离满足要求的情况下，能够由测距装置输出提示信号。该处的提示信号的输出方式和之前所描述的输出方式一致，即既能够通过例如测距装置自身所装备有的蜂鸣器发出声音，也能够通过测距装置自身所装备有的显示屏或者提示灯输出光学信号，当然也能够通过测距装置的通信接口例如通过蓝牙接口或者WiFi接口将该提示信号输出至诸如手机的便携式手持设备，以便更好地输出提示信号。
在此，虽然所示出的空间402是规则形状的，而且物体401也是规则形状的，但是本发明的构思即发明精神并不限于规则形状的物体和规则形状的空间。也就是说，即便物体401和/或空间402的形状是不规则的，依据本发明的构思也同样能够实现物体401在空间402中的布局。
以下将借助于图5来描述例如所布置的空间不是矩形这样的规则形状时如何布置物体。图5示出了借助于前述的测距装置以及定位方法在目标空间中对目标物体实施定位的第二实施例的过程示意图500。
从图5中可以看出，目标空间例如是椭圆形的，此时的定位方法和之前的并没有太大区别。具体过程如下：为了将物体501布置在空间502的图示横向上的居中处，首先需要借助于测距装置100测量空间502在图示横向上的距离d501，然后，需要借助于测距装置100测量待放置的物体501在图示横向上的距离d502，本领域的技术人员应当了解，此处的距离d501及d502均已包括测距装置本身的尺寸。由于目标是将物体501布置在空间502的图示横向上的居中处，所以只要使得物体501和空间502图示横向上的边之间的距离d503为(d501-d502)/2便能满足要求了。此时，既能够将测距装置100靠在墙边上，判断测距装置100离物体501的距离是否满足要求；也能够将测距装置100放置在物体501离墙边更近的边上使得测距装置100随着物体501一起从虚线位置移动至实线位置，判断测距装置100离物体501的距离是否满足要求即可。在所测的距离满足要求的情况下，能够由测距装置输出提示信号。该处的提示信号的输出方式和之前所描述的输出方式一致，即既能够通过例如测距装置自身所装备有的蜂鸣器发出声音，也能够通过测距装置自身所装备有的显示屏或者提示灯输出光学信号，当然也能够通过测距装置的通信接口例如通过蓝牙接口或者WiFi接口将该提示信号输出至诸如手机的便携式手持设备，以便更好地输出提示信号。
本领域的技术人员应当了解，上述的空间502以及物体501的尺寸既能够通过测距装置测量来获得，也能够通过例如测距装置的人机交互界面HMI来输入，例如能够直接通过测距装置100的通信接口接收待摆放的空间、待摆放的物体以及摆放要求的布局图，进而根据该布局图输出提示信号。
此外，借助于依据本发明的测距装置100不仅能够在一个维度上按照要求来摆放物体，也能够在二维以及三维或者更多的维度上按照要求来摆 放物体。以下将借助于图6来描述如何借助于依据本发明的测距装置100来满足二维平面上的摆放要求，其实三维空间中的摆放要求按照本发明的精神同样可以实现。
图6示出了借助于前述的测距装置以及定位方法在目标空间中对目标物体实施定位的第三实施例的过程示意图600。
从图6中可以看出，目标空间例如是长方形的，此时的定位方法和之前的并没有太大区别。具体过程如下：为了将物体601布置在空间602的图示横向上的居中处，首先需要借助于测距装置100测量空间602在图示横向以及纵向上的距离d6011以及d6012，本领域的技术人员应当了解，此处的距离d6011及d6012均已包括测距装置本身的尺寸。然后，需要借助于测距装置100测量待放置的物体501在图示横向以及纵向上的距离d6021以及d6022，由于目标是将物体601布置在空间602的图示横向上的居中处，所以只要使得物体601和空间602图示横向上的边之间的距离d6031为(d6011-d6021)/2并且使得物体601和空间602图示纵向上的边之间的距离d6032为(d6012-d6022)/2便能满足要求了。此时，既能够将测距装置100靠在墙边上，判断测距装置100离物体601的距离是否满足要求；也能够将测距装置100放置在物体601离墙边更近的边上使得测距装置100随着物体601一起从虚线位置移动至实线位置，判断测距装置100离物体601的距离是否满足要求即可。在所测的距离满足要求的情况下，能够由测距装置输出提示信号。该处的提示信号的输出方式和之前所描述的输出方式一致，即既能够通过例如测距装置自身所装备有的蜂鸣器发出声音，也能够通过测距装置自身所装备有的显示屏或者提示灯输出光学信号，当然也能够通过测距装置的通信接口例如通过蓝牙接口或者WiFi接口将该提示信号输出至诸如手机的便携式手持设备，以便更好地输出提示信号。
虽然所示出的空间602是规则形状的，而且物体601也是规则形状的，但是本发明的构思即发明精神并不限于规则形状的物体和规则形状的空间。也就是说，即便物体601和/或空间602的形状是不规则的，依据本发明的构思也同样能够实现物体601在空间602中的布局。此外，本领域的技术人员应当了解，上述的空间602以及物体601的尺寸既能够通过测距装置测量来获得，也能够通过例如测距装置的人机交互界面HMI来输入，例如能够直接通过测距装置100的通信接口接收待摆放的空间、待摆放的 物体以及摆放要求的布局图，进而根据该布局图输出提示信号。
再者，两个维度的尺寸参数的获取既能够通过单一维度的测距装置通过两次测量来获取，也能够通过具有两个维度上的测量单元的测距装置一次实现。
此外，根据图6所示出的原理，也能够将高度要求增加至预定规则之中，从而实现三维的定位。
图4至图6示出了在长度这一维度上的空间定位，除此之外，依据本发明的测距装置以及相对应的方法同样能够实现例如弧线维度上的定位，图7示出了借助于前述的测距装置以及定位方法在目标空间中对目标物体实施定位的第四实施例的过程示意图700。
从图中可以看出，当需要将物体701摆放在空间702的线720和线730之间的弧线710之上时，首先需要通过测距装置100获得例如弧线710的长度或者线720和线730之间的角度β，然后再按照所接收的或者所存储的预定规则的要求，例如三等分或者将物体701摆置在与线720成α角度的弧线710处，此时便能够通过测距装置输出提示信号，以便将物体701摆置在所要求的位置。这一应用非常适合诸如歌剧院等的演出场所的诸如座椅的摆放之中。
在上述的实施例之中，测距装置所测量出的尺寸均已包括测距装置自身的尺寸在内。
本领域技术人员应当理解，上面公开的各个实施例可以在不偏离发明实质的情况下做出各种变形和修改。因此，本发明的保护范围应当由所附的权利要求书来限定。
尽管已经描述了本发明的不同示例性的实施例，但对于本领域技术人员而言显而易见的是，能够进行不同的改变和修改，其能够实现本发明的优点中的一些而不背离本发明的精神和范畴。对于那些在本领域技术中相当熟练的人员来说，执行相同功能的其他部件可以适当地被替换。应提到，在此参考特定的附图解释的特征可以与其他附图的特征组合，即使是在那些没有明确提及此的情况中。此外，可以或者在所有使用恰当的处理器指令的软件实现方式中或者在利用硬件逻辑和软件逻辑组合来获得同样结果的混合实现方式中实现本发明的方法。这样的对根据本发明的方案的修改旨在被所附权利要求所覆盖。
