具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，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，都应当属于本申请保护的范围。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或模块或单元的过 程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或模块或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或模块或单元。
根据本申请实施例，提供了获取仪表读数的方法。图1是根据本申请实施例的获取仪表读数的方法的流程图。如图1所示，根据本申请实施例的获取仪表读数的方法包括：在步骤S101，获取仪表的图像。然后在步骤S103，在图像中检测仪表的刻度线和指针。接下来，在步骤S105，在基于仪表的量程的最大数值和最小数值以及在仪表的表盘中最大数值的刻度线与最小数值的刻度线之间的角度确定每一个单位角度对应的单位数值。接下来，在步骤S107，基于指针与最小数值的刻度线之间的角度确定与读数对应的读数角度。接下来，在步骤S109，基于读数角度与每一个单位角度对应的单位数值确定仪表的读数。
例如，在步骤S101中获取的仪表图像如图4所示，其中，仪表具有圆形的表盘，仪表的量程的数值以及对应的刻度以环形布置在表盘中。仪表可以是指示相关联的仪器的状态的仪表。在步骤S103检测如图4所示的仪表中的刻度线和指针。例如，在步骤S105中确定仪表的表盘中最大数值的刻度线与最小数值的刻度线之间的角度确定量程的角度范围，进而确定每一个单位角度对应的单位数值。图5是根据本申请的示例性实施例的仪表的图像中被分划的表盘的示意图，如图5所示，其中示意性地示出了表盘被按照单位角度进行平均划分，表盘整个角度范围为360°，每10°作为一个划分，多个划分中的每个划分对应于单位角度的单位数值，即，每个划分对应于“每10°的数值”。可以理解，仪表的读数与仪表的指针的角度是对应的，通过测量指针与仪表的量程的最小数值的刻度线之间的角度可以确定仪表读数对应的角度，将仪表读数对应的角度乘以每一个单位角度对应的单位数值，即可确定指针所指示的仪表读数。
图6是根据本申请的示例性实施例的仪表的图像中指针所指示的读数角度的范围的示意图。例如，在图6中，基于指针与最小数值的刻度线之间的角度确定与读数对应的读数角度。在图6示出的实例中，仪表的量程为0-100。最小数值0在表盘中的角度为min°，最大数值100的max°，因此，0-100的量程所对应的角度范围为从min°-max°，将该角度范围平均分为多个划分，每个划分对应单位角度，单位角度对应的单位数值为(100-0)/(max°-min°)，即“每单位角度的数值”。如果确定仪表的指针所指示的角度(指针的角度与最小值刻度的角度的角度差)为value°，那么，如图6所示的仪表的读数为：value°×(100-0)/(max°-min°)。此外，可以理解，对于量程的最小值不是0的仪表，该仪表的读数应当为：该仪表的最小值+value°×(该仪表的最大值-该仪表的最小值)/(max°-min°)。以这样的方式，通过分析 仪表的图像，基于仪表的量程范围、最大数值和最小数值与指针的角度，能够在获取仪表的图像之后通过自动对图像进行分析和处理获取仪表的读数，节省了读取仪表读数的时间和人力。
图2是根据本申请的示例性实施例的方法的流程图。如图2所示，根据本申请的示例性实施例的方法还包括：步骤S201，在获取仪表的图像之前，获取包括唯一识别仪表的识别符的识别符图像，其中，识别符与仪表的仪表信息相关联，仪表信息指示仪表的量程的最大数值和最小数值以及在仪表的表盘中最大数值的刻度线的角度和最小数值的刻度线的角度。接下来，在步骤S203，检测识别符以根据识别符与仪表信息之间的关联获取仪表信息。接下来，在步骤S205，基于在仪表的表盘中最大数值的刻度线的角度和最小数值的刻度线的角度确定最大数值的刻度线与最小数值的刻度线之间的角度。
例如，识别符可以是QR码。每个仪表设置有单独的QR码，仪表与QR码两者关联，扫描该QR码可知该仪表的数据库，从而获取例如仪表的类型、制造商、外观等信息。QR码不必须设置在仪表上，而是可以设置在容易访问的位置，但仪表的位置仍然需要根据实际使用环境和需求设置。
图3是根据本申请的示例性实施例的方法的流程图。如图3所示，根据本申请的示例性实施例，在步骤S301，在获取仪表的图像之前，获取包括唯一识别仪表的识别符的识别符图像，其中，识别符与仪表的仪表信息相关联，仪表信息指示仪表的量程的最大数值和最小数值以及在仪表的表盘中最大数值的刻度线的角度和最小数值的刻度线的角度，仪表信息还指示仪表的位置。在步骤S303，根据仪表的位置确定拍摄仪表的图像的相机位置。在步骤S305，将相机移动到相机位置以用于拍摄仪表的图像。
图7是根据本申请的示例性实施例的仪表信息的示意图。如图7所示，仪表信息包括“Key”和“Value”两列数据，分别表示仪表信息的名称和对应的值。仪表信息包括仪表名称、仪表位置、仪表形状、仪表图片、仪表量程的最大值、最小值以及仪表量程的最大值、最小值所对应的角度值。仪表的仪表信息可以用于识别该仪表，以及根据仪表的量程的最大值、最小值以及仪表量程的最大值、最小值所对应的角度值根据如上方法确定仪表的读数。
仪表的位置信息例如包括仪表的物理定位、悬架的相对高度、仪表的水平角度等。在仪表所在的环境中，详细的位置信息可以帮助图形采集工具(例如设有相机的能移动的装置)快速定位仪表并找到仪表以及拍摄仪表的图像的拍摄位置，获得更清晰、更完整的仪表图像。
图8是根据本申请的示例性实施例的方法的示意图。如图8所示，801是设有仪表的环境的边界或者墙壁，803是移动通道，807是携带相机的机器人，在移动通道803中行进并沿途寻找仪表的QR码。机器人807从充电位置805出发开始在移动通道803中行进后，沿途扫描到QR码813，根据QR码813获取仪表信息，如图7所示。然后根据仪表信息确定与QR码813关联的仪表813’的位置，将携带的相机移动到拍摄仪表813’的拍摄位置，拍摄813’的仪表图像，结合如图7所示的仪表信息以及据本申请实施例的获取仪表读数的方法可以确定仪表813’的读数。机器人807继续在移动通道803中行进，扫描QR码815，并移动相机以拍摄相关联的仪表815’的仪表图像。机器人807继续在移动通道803中行进，扫描QR码811，并移动相机以拍摄相关联的仪表811’的仪表图像。如此方式，在实际应用中，可以根据扫描的QR码获得的位置信息引导携带相机的机器人到达仪表的位置，并根据仪表的具体的高度、角度信息，通过机器人携带的相机拍摄仪表当前的完整图片，使得能够自动寻找环境中的QR码和仪表，实现自动获取仪表读数。
以这样的方式，能够在获取仪表的图像之前确定要获取图像的仪表的量程、数值和刻度线等用于确定仪表读数的信息，能够在获取仪表的图像前获取仪表的位置信息并将相机移动到拍摄仪表图像的相机位置，实现相机拍摄位置的自动化控制。
根据本申请的示例性实施例，检测仪表的刻度线和指针包括：在图像中确定仪表的环形边缘和中心；在图像中确定在仪表的环形边缘内排列的仪表的刻度线；以及在图像中确定仪表的指针，其中，图像中最接近仪表的中心的直线代表仪表的指针。图9是以直线示出根据本申请的示例性实施例的仪表的指针的示意图。如图9所示，在进行图像处理的过程中所确定的最接近仪表的中心的直线代表仪表的指针。
具体地，仪表所表示的数据由以下方法确定：
A，仪表的圆形轮廓和中心可以通过霍夫变换-环形检测来识别。
B，通过霍夫变换-线检测，识别仪表的表盘中的直线，例如环形围绕仪表中心排列的刻度线和指针。
在B中识别的这些线在A中识别的仪表的圆形轮廓中，并且刻度线的长度在圆形轮廓的圆形半径的一定的误差范围内，指针的线的两端在仪表的轮廓内。
C，识别在B中确定的表示仪表指针的线。该线是最接近圆形轮廓的中心的直线。并且，仪表的第一个刻度和最后一个刻度的直线均在仪表的圆形轮廓的范围内。
以这样的方式，处理仪表的图像以获得用于确定仪表读数的信息。
根据本申请的示例性实施例的方法还包括在获取仪表的图像之后且检测仪表的刻度线和指针之前：识别图像中仪表的仪表区域和仪表之外的区域；以及在图像中去除仪表之外的区域并保留仪表的仪表区域。
图10A是根据本申请的示例性实施例的包括仪表的仪表区域和仪表之外的区域的图像的示意图。图10B是根据本申请的示例性实施例的仅包括仪表的仪表区域的图像的示意图。相机在拍摄位置拍摄的仪表的图像可能包含识别仪表读数的信息之外的不需要的图像信息，因此，在识别仪表的刻度线和指针等之前，排除这些不需要的仪表之外的区域的图像信息，仅留下包括仪表的仪表区域。可以通过深度学习和神经网络技术，执行关于仪表的预建模训练(pre-model training)，从而用于识别图像中的仪表，帮助确定仪表区域。以这样的方式，能够提高处理仪表图像的信息的精确度并且减少获取仪表读数的处理的数据量。
根据本申请实施，还提供了获取仪表读数的装置。图11是根据本申请实施例的获取仪表读数的装置的示意图。如图11所示，根据本申请实施例的获取仪表读数的装置1包括：相机101，被配置为获取仪表的图像；检测模块103，被配置为在图像中检测仪表的刻度线和指针；以及处理器105，被配置为：基于仪表的量程的最大数值和最小数值以及在仪表的表盘中最大数值的刻度线与最小数值的刻度线之间的角度确定每一个单位角度对应的单位数值；基于指针与最小数值的刻度线之间的角度确定与读数对应的读数角度；以及基于读数角度与每一个单位角度对应的单位数值确定仪表的读数。以这样的方式，能够在获取仪表的图像之后通过自动对图像进行分析和处理获取仪表的读数，节省了读取仪表读数的时间和人力。

根据本申请的示例性实施例，仪表信息还指示仪表的位置，并且获取仪表读数的装置1还包括：相机位置确定模块107，被配置为根据仪表的位置确定拍摄仪表的图像的相机位置；以及相机移动模块109，被配置为将相机移动到相机位置以用于拍摄仪表的图像。以这样的方式，能够在获取仪表的图像前获取仪表的位置信息并将相机 移动到拍摄仪表图像的相机位置，实现相机拍摄位置的自动化控制。
根据本申请的示例性实施例，检测仪表的刻度线和指针包括：通过检测模块在图像中确定仪表的环形边缘和中心；通过检测模块在图像中确定在仪表的环形边缘内排列的仪表的刻度线；以及通过检测模块在图像中确定仪表的指针，其中，图像中最接近仪表的中心的直线代表仪表的指针。以这样的方式，处理仪表的图像以获得用于确定仪表读数的信息。
根据本申请的示例性实施例，装置1还包括仪表区域确定模块111，仪表区域确定模块111被配置为在获取仪表的图像之后且检测仪表的刻度线和指针之前：识别图像中仪表的仪表区域和仪表之外的区域，以及在图像中去除仪表之外的区域并保留仪表的仪表区域。以这样的方式，能够提高处理仪表图像的信息的精确度并且减少获取仪表读数的处理的数据量。
