具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
在拼接屏技术方案中，拼接屏部分在物理安装拼接后，需要进行复杂的配置、连线。拼接屏控制系统一般配套对应的配置软件，物理连线需要根据软件设计进行对应连线。例如，通过软件人工完成对拼接屏进行编排，实现各拼接屏和对应通道的对应；手工调整物理端口，以达到编排拼接屏的目的。
图1所示为一拼接屏应用场景的组网结构示意图。如图1所示，显示屏101～109组成拼接屏，图像控制器110将需要拼接屏显示的图像信号输出到显示屏101～109。
一般的，显示屏101～109的图像信号输入是相互独立的，图像控制器110在实质上是将需要显示的图像，按照拼接屏中显示屏101～109的数量进行分割，获取显示屏101～109中每个显示屏需要显示的图像的图像信号，然后将每个显示屏需要显示的图像的图像信号通过分别输出到对应的显示屏。
为了使得显示屏101～109可以正确显示图像，使用控制端120设置图像控制器110。具体的，设定当前的拼接屏是由9个显示屏以3*3的方式组合而成，每个显示屏横屏。图像控制器110按照设定，会将需要在拼接屏上显示的图像分割为如111～119的9个图像，9个图像(111～119)分别由图像控制器110的输出接口121～129输出，显示屏101～109分别连接到图像控制器110的输出接口121～129。
在图1所示应用场景中，控制端120需要安装专业软件进行拼接屏编排，用户需要在控制端120上进行拼接屏编排的相关参数设置，并且，根据控制端120上的设置对应的进行图像控制器110与显示屏101～109间的物理连线安装。参数设置和物理连线安装的操作过程复杂，导致用户学习成本高，难以自行完成安装，需要专业人员上门支持。并且，在参数设置和物理连线安装的过程中，即使由专业人员操作，人工操作错误也可能导致多次反复调整。
为简化拼接屏方案实现过程中物理连线安装的操作复杂程度，一种可行的方案是，在 控制端120上设定图像(111～119)与显示屏101～109间的对应关系，将图像(111～119)与显示屏101～109的硬件标识(例如，显示屏地址)一一绑定，由图像控制器110根据图像(111～119)与显示屏101～109间的对应关系，调配自己的输出接口，将图像(111～119)分别输出到显示屏101～109。这样，技术人员在将显示屏101～109连接到图像控制器110上时，就不需要区分图像控制器110输出图像(111～119)的具体接口，从而大大降低了物理连线安装的操作复杂程度。
上述方案虽然大大降低了物理连线安装的操作复杂程度，但是，由于在设置图像控制器110是需要输入图像(111～119)与显示屏101～109的硬件标识间的对应关系，因此，在安装拼接屏时需要用户记录每一个显示屏安装位置上的显示屏的硬件标识，参数设置和物理连线安装的操作过程依然具备相当的复杂程度，用户任然难以自行完成安装，需要专业人员上门支持。
因此，进一步的，在本申请一实施例中，提出了一种自动进行显示屏定位的方法，自动识别拼接屏中显示屏的拼接方式以及每一个显示屏安装位置上的显示屏的硬件标识，从而在设置图像控制器的过程中不需要手工输入分割图像与显示屏的硬件标识间的对应关系。
进一步的，超宽带(Ultra Wide Band，UWB)技术是一种无线载波通信技术，它不采用正弦载波，而是利用纳秒级的非正弦波窄脉冲传输数据，因此其所占的频谱范围很宽。UWB技术具有系统复杂度低，发射信号功率谱密度低，对信道衰落不敏感，截获能力低，定位精度高等优点，尤其适用于室内等密集多径场所的高速无线接入。在UWB技术应用中，可以通过到达时间(Time of Arrival，TOA)/到达时间差(Time Difference of Arrival，TDOA)测距技术测量UWB设备到UWB标签的距离，并且，可以通过到达角度(Angle of Arrival，AOA)测向技术，获取UWB设备指向UWB标签的方向角。
因此，在本申请实施例的技术方案中，基于UWB技术进行显示屏定位。具体的，构造一个UWB基点设备以及多个UWB标签，在拼接屏中每一个显示屏上安装UWB标签显示屏的硬件标识与其上所安装的UWB标签的标识绑定，即，通过UWB标签可以区分不同的显示屏。测量UWB设备到每一个UWB标签的距离和/或指向每一个UWB标签的方向角，从而计算多个UWB标签的相互位置关系，进而确定拼接屏中各个显示屏相互间的位置关系以定位拼接屏中的显示屏。
具体的，本申请一实施例中提出了一种拼接屏定位方法，方法包括：
基于UWB测距以及UWB测向技术，获取UWB基点设备到UWB标签的距离和/或方向，其中，多台显示屏拼接成拼接屏，每台显示屏上安装一个UWB标签，不同的显示屏可以基于其安装的UWB标签进行区分；
根据UWB基点设备分别到每个UWB标签的距离和/或方向，计算UWB标签的相互位置关系，根据UWB标签的相互位置关系确认拼接屏中各个显示屏的位置。
根据本申请一实施例的方法，可以简单方面的确认拼接屏中各个显示屏的位置，从而实现对拼接屏的显示配置；相较于现有技术，根据本申请一实施例的方法，可以大大降低拼接屏技术方案的实施难度，从而有利于拼接屏技术的推广应用。
进一步的，在本申请实施例的应用场景中，拼接成拼接屏的多台显示屏在尺寸上一致，显示屏为矩形，拼接成的拼接屏也为矩形。例如，4个尺寸相同的显示屏采用2*2的方式 拼接成拼接屏、6个尺寸相同的显示屏采用3*2的方式拼接成拼接屏、9个尺寸相同的显示屏采用3*3的方式拼接成拼接屏。
进一步的，为了便于计算UWB标签相互位置关系，在本申请一实施例中，拼接成拼接屏的多台显示屏上，安装UWB标签的安装位置一致。例如，在每台显示屏的右上角安装UWB标签，或者，在每台显示屏的中心点安装UWB标签，或者，在每台显示屏的中心线上特定位置安装UWB标签。
图2所示为根据本申请一实施例的应用场景示意图。如图2所示，显示屏201～209以3*3的方式组成拼接屏，UWB标签211～219分别安装在显示屏201～209上。UWB基点设备220基于UWB测距以及UWB测向技术，获取UWB基点设备220分别到UWB标签211～219的距离以及方向。根据UWB基点设备220分别到UWB标签211～219的距离以及方向，即可确认UWB标签211～219相互间的位置关系。
在根据本申请实施例的具体应用场景中，可以采用多种不同的方法计算UWB标签相互间的位置关系。
例如，由于UWB标签位于同一个平面上，可以根据UWB基点设备分别到UWB标签的方向角，计算UWB标签相互间的位置关系。图3所示为根据本申请一实施例的应用场景示意图。如图3所示，显示屏301～309以3*3的方式组成拼接屏，UWB标签311～319分别安装在显示屏301～309上。以UWB标签311、312、314为例。以UWB基点设备320到UWB标签311的指向为基准，UWB基点设备320到UWB标签312的指向为向右偏转，即可确认UWB标签212在UWB标签211的右方；UWB基点设备320到UWB标签314的指向为向下偏转，即可确认UWB标签314在UWB标签311的下方。
又例如，在实际应用场景中，在已知三角形两条边的边长以及该两条边的夹角的情况下，即可计算第三边的长度。那么，当已知UWB基点设备分别到两个UWB标签的距离(两条边的边长)以及UWB基点设备分别到两个UWB标签的方向(指向的夹角为两条边的夹角)，就可以计算两个UWB标签间的距离(第三边的边长)。图4所示为根据本申请一实施例的应用场景示意图。如图4所示，显示屏401～409以3*3的方式组成拼接屏，UWB标签411～419分别安装在显示屏401～409上。以UWB标签411、412为例，UWB基点设备420到UWB标签411的距离为a 4，UWB基点设备420到UWB标签412的距离为b 4。根据UWB基点设备420分别到UWB标签411以及412方向可以计算角A 4。根据a 4、b 4以及角A 4就可以计算UWB标签411以及412的间距c 4。
进一步的，在拼接屏中，由于显示屏组成矩形，并且UWB标签在显示屏上的安装位置一致，因此，UWB标签构成矩形。由于在矩形中最长的线段为矩形的对角线，那么，在拼接屏中，间距最长的两个UWB标签即为UWB标签所构成矩形的矩形顶点上的UWB标签。因此，根据UWB基点设备分别到每个UWB标签的距离以及方向，计算两两UWB标签间的距离，确认两两UWB标签间的距离最大的两对UWB标签，就可以定位拼接屏上四角的显示屏的UWB标签。以四角的UWB标签为基点，就可以进一步定位其他的UWB标签。
图5所示为根据本申请一实施例的应用场景示意图。如图5所示，显示屏501～509以3*3的方式组成拼接屏，UWB标签511～519分别安装在显示屏501～509上。计算UWB标签511～519中任意两个UWB标签的间距，其中，UWB标签511与519的间距以及UWB 标签513与517的间距为最大的两个间距。因此可以定位UWB标签511、513、517以及519分别为处于四个角上的显示屏上所安装的UWB标签。进一步的，根据UWB基点设备分别到UWB标签511、513、517以及519的方向，即可确认UWB标签511位于左上角、UWB标签513位于右上角、UWB标签517位于左下角、UWB标签519位于右下角。进一步的，以UWB标签511、513、517以及519为基点，根据UWB基点设备分别到UWB标签512、514、515、516以及518的方向，即可定位UWB标签512、514、515、516以及518的位置。
进一步的，在实际应用场景中，某些显示屏的尺寸并不是正方形，其长度和宽度是不同的。因此，显示屏横屏放置(长边水平)和竖屏放置(短边水平)时，其显示画面的状态也是不同的。那么，在显示屏数量不变、显示屏相对位置不变的情况下，横屏放置的显示屏拼接成的拼接屏与竖屏放置的显示屏拼接成的拼接屏，也存在显示画面的状态区别。
针对上述情况，在本申请一实施例中，除了定位拼接屏中显示屏的位置，还识别拼接屏中显示屏的横/竖屏状态。具体的，在实际应用场景中，可以采用多种不同的方式识别显示屏的横/竖屏状态。例如，基于用户输入的横/竖屏状态参数识别显示屏的横/竖屏状态。又例如，在显示屏上安装方向传感器，根据方向传感器的识别结果确定显示屏的横/竖屏状态。
在本申请一实施例的拼接屏定位方法中，根据UWB基点设备分别到每个UWB标签的距离和方向，确认拼接屏中显示屏的横/竖屏状态。
具体的，图6所示为根据本申请一实施例的部分方法流程图。识别显示屏的横/竖屏状态的过程如图6所示：
步骤610，根据UWB基点设备分别到每个UWB标签的距离以及方向计算任意两个UWB标签的间距；
步骤620，确定间距最长的两对UWB标签以确定最大UWB标签四边形；
步骤630，计算最大UWB标签矩形的边长以确定UWB标签四边形的最长边/最短边；
步骤640，确定UWB标签四边形的最长边/最短边的方向，根据UWB标签四边形的最长边/最短边的方向确定拼接屏中显示屏的横/竖屏状态。
图7所示为根据本申请一实施例的应用场景示意图。如图7所示，显示屏701～709以3*3的方式组成拼接屏，UWB标签711～719分别安装在显示屏701～709上。计算UWB标签711～719中任意两个UWB标签的间距，其中，UWB标签511与519的间距以及UWB标签513与517的间距为最大的两个间距。因此可以定位UWB标签511、513、517以及519分别为处于四个角上的显示屏上所安装的UWB标签，构成最大UWB标签四边形。进一步的，计算最大UWB标签四边形的边长(511与513、511与517、513与519、517与519的间距)，511与513、517与519的间距大于511与517、513与519的间距，则511～513、517～519为最大UWB标签四边形的长边。确定511～513、517～519为水平方向，则显示屏701～709为横屏状态。
进一步的，在实际应用场景中，显示屏存在顶部/底部的区分。图8所示为根据本申请一实施例的应用场景示意图。图8所示显示屏801中的箭头所示方向指向显示屏的顶部。一般的，在显示屏横屏放置时，显示画面默认显示屏的顶部为画面的上方。
那么，当两个显示屏的纵向中线位于同一直线上时，其顶部朝向关系就存在同向、逆 向以及对向三种关系。图9所示为根据本申请一实施例的应用场景示意图。在图9中，910所示的两个显示屏的顶部朝向关系为同向(顶部均向上)；920所示的两个显示屏的顶部朝向关系为同向(顶部均向下)；930所示的两个显示屏的顶部朝向关系为逆向；940所示的两个显示屏的顶部朝向关系为对向；950所示的两个显示屏的顶部朝向关系为同向(顶部均向左)；960所示的两个显示屏的顶部朝向关系为同向(顶部均向右)；970所示的两个显示屏的顶部朝向关系为逆向；980所示的两个显示屏的顶部朝向关系为对向。
当两个显示屏的横向中线位于同一直线上时，其顶部朝向关系就存在同向、逆向两种关系。图10所示为根据本申请一实施例的应用场景示意图。在图10中，1010所示的两个显示屏的顶部朝向关系为同向(顶部均向上)；1020所示的两个显示屏的顶部朝向关系为同向(顶部均向下)；1030所示的两个显示屏的顶部朝向关系为逆向；1050所示的两个显示屏的顶部朝向关系为同向(顶部均向左)；1060所示的两个显示屏的顶部朝向关系为同向(顶部均向右)；1070所示的两个显示屏的顶部朝向关系为逆向。
针对上述两个显示屏间存在的顶部朝向关系。在本申请一实施例中，为了确保图像在拼接屏上可以正确显示，不仅需要确定拼接屏中各个显示屏的位置，还要确认拼接屏中显示屏的顶部朝向关系。具体的，在实际应用场景中，可以采用多种不同的方式确认显示屏的顶部朝向关系。例如，基于用户输入的显示屏顶部朝向参数确认显示屏的顶部朝向关系。又例如，在显示屏上安装方向传感器，根据方向传感器的识别结果确定显示屏的顶部朝向，从而确定显示屏的顶部朝向关系。
具体的，在本申请一实施例的拼接屏定位方法中，根据UWB基点设备分别到每个UWB标签的距离以及方向，确认拼接屏中相邻的显示屏的顶部朝向关系，其中，当两个显示屏的纵向中线位于同一直线上时，顶部朝向关系包括同向、逆向以及对向；当两个显示屏的横向中线位于同一直线上时，顶部朝向关系包括同向以及逆向。

当UWB标签偏向显示屏顶部的一侧时，当相邻两个UWB标签的间距大于显示屏的高度时，两个显示屏逆向；
当UWB标签偏向显示屏底部的一侧时，当相邻两个UWB标签的间距小于显示屏的 高度时，两个显示屏逆向；

进一步的，根据本申请实施例所提出的拼接屏定位方法，本申请一实施例还提出了一种拼接屏定位装置。拼接屏定位装置包括：

进一步的，在某些技术方案中，对于一个技术的改进可以很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field Programmable Gate Array，FPGA))就是这样一种集成电路，其逻辑功能由访问方对器件 编程来确定。由设计人员自行编程来把一个数字装置“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。
在本申请实施例的描述中，为了描述的方便，描述装置/系统时以功能分为各种模块分别描述，各个模块的划分仅仅是一种逻辑功能的划分，在实施本申请实施例时可以把各模块的功能在同一个或多个软件和/或硬件中实现。
