本申请实施例中，测量支架100被置于相对于车辆的位置是指测量支架被置于相对于车辆的指定或者预设位置，或者测量支架100被置于相对于车辆的指定范围内的任意位置。为了能够使标定元件或者轮图像采集组件定位准确，进而不影响标定精度或者采集图像的精度，通常承载标定元件或者轮图像采集组件的测量支架100会被规定其相对于车辆的位置，该规定可记录在用户操作手册上，用户可通过其记录步骤逐步将测量支架进行精准定位，或者该规定可以可执行程序的方式由处理器执行，处理器可以输出控制指令以驱动测量支架自动定位至指定或预设位置。标定元件或者轮图像采集组件可固定或者活动地安装于测量支架100，若标定元件400或者轮图像采集组件可活动地安装于测量支架100，可以调节其与测量支架100之间的活动机构使其精准定位至预设位置。或者，标定算法或轮检测算法允许一定的误差，则可以将测量支架100置于相对于车辆的指定范围内，测量支架100只要在该指定范围内，则可以通过后续的标定算法或者轮检测算法对其定位误差进行校准。
在本申请实施例中，所述测量支架100被置于车辆的前方。
可以理解，根据实际需要，在其他一些实施例中，所述测量支架被置于车辆的侧方或后方。轮所处区域可以是轮附近的空间范围内，如一些场景下，轮上安装有携带图案的标靶，则轮图像采集组件的视野范围需覆盖标靶，以结合处理器300通过识别标靶上携带的图案对轮进行定位，轮所处区域也可以是轮所占据的空间范围，又如在另一些场景下，轮图像采集组件仅需采集轮的图像，结合处理器300识别轮图像即可对轮进行定位。
轮图像采集组件对于所采集的图像可以是静态的。例如，车辆在静态的状态下，即车辆相对于地面不发生位置移动的情况下，轮图像采集组件根据采集的车轮的静态图像进行处理。
轮图像采集组件对于所采集的图像也可以是动态的。例如，车辆在动态的状态下，如车辆在一定范围内行驶的过程中，轮图像采集组件根据采集的车轮的动态图像进行处理。
两个轮图像采集组件200a，200b之间横向间隔距离可以根据车辆的宽度确定。在一些实施例中，两个轮图像采集组件200a，200b之间的横向间隔距离可调，或者，两个轮图像采集组件之间的横向间隔距离固定。
在其他一些实施例中，两个轮图像采集组件200a，200b还可以通过其他方式横向间隔设置，例如，支撑架上设置有对称两臂，两臂中各臂的一端与支撑架连接，各臂的另一端安装有轮图像采集组件，在此种情况下，支撑架上两臂的运动为同步的，可以设置两臂的臂长，或者两臂的高度可调节。对于本申请实施例中两个轮图像采集组件的横向间隔的实现方式，本申请不予限定。
在一些实施例中，两个轮图像采集组件200a，200b可拆卸地安装于安装梁32，即两个轮图像采集组件200a，200b可以作为测量支架100的配件形式存在，当仅需要实现ADAS标定功能时，无需安装轮图像采集组件，若需要计算轮状态参数，或者对车辆的轮进行检测时，则将两个轮图像采集组件200a，200b安装于安装梁32，两个轮图像采集组件200a，200b可固定或者活动地安装于安装梁32。为了保证轮图像采集组件的安装精度不影响轮状态参数的计算，可以在安装梁32上对轮图像采集组件的安装位置进行标识，或者设计特殊的安装方式，能够使轮图像采集组件安装于安装梁32的预设位置上。
所述轮图像采集组件可以是仅具有采集图像功能的装置，如图像采集传感器、相机或摄像机等装置，也可以为具有采集图像功能且能够对图像进行处理的装置，可对图像进行格式转换，存储，像素计算、裁减或赋值等处理。

所述处理器300分别与所述两个轮图像采集组件200a，200b电性连接，如有线连接或无线连接，所述处理器300用于根据所述两个轮图像采集组件200a，200b所采集的数据，测量所述车辆的轮状态，以对轮进行定位，包括全面测量轮的各项定位参数，如外倾角、前束角等；或者检测轮是否需要被定位，可通过简易算法，仅判断车轮当前状态是否需要进行全面检测，即进一步进行上述的对轮进行定位，在此，本申请实施例对于检测轮是否需要被定位的算法或方式不予限定。
在一些实施例中，所述车辆测量设备还可以包括输出器500。所述输出器500与所述处理器300电连接，用于提示用户所述处理器500的输出结果，所述输出器可包括显示屏、发声器等中的至少一种。

车辆驾驶系统根据功能不同，可分为自适应巡航系统，盲点系统，车辆偏离警示系统等。所述自适应巡航系统主要包括雷达，所述自适应巡航系统的雷达可以是单雷达或者双雷达，单雷达一般设置在车辆的车头中间，双雷达一般设置在车辆的车头两侧。可通过自适应巡航系统标定元件对所述自适应巡航系统中的雷达进行标定，所述自适应巡航系统标定元件可以为雷达标定板(用于 反射雷达发射的波)，雷达标定盒，角反射器等雷达标定件。所述盲点系统主要包括雷达，所述盲点系统的雷达一般设置在车尾处，可通过盲点检测系统标定元件对所述盲点系统进行标定，所述盲点检测系统标定元件可以为多普雷发生器，也即盲点盒子、雷达标定盒，等等。所述车辆偏离警示系统主要包括车辆的车窗上的摄像头，可通过图案板对所述车辆偏离警示系统进行标定。
可选地，安装梁32可拆卸地安装于支撑架31，安装梁32可分为多种进行替换，以适应不同的应用场景，例如，第一安装梁上固定连接有轮图像采集组件，第二安装梁上可用于挂载标定元件，第一安装梁或第二安装梁可拆卸地安装于支撑架，对于轮定位场景，可将第一安装梁安装至支撑架，对于标定车辆场景，可将第二安装梁安装至支撑架。由于第一安装梁通常置于立架组件的上部(如图1所示)，需要重量较轻的材质制成，第二安装梁为了保证支撑标定元件而不变形，通常需要一定重量或刚性的材料制成，通过此种方式，可以更好地将安装梁适用对应的应用场景；或者，安装梁可以同时连接轮图像采集组件，以及可挂载标定元件。
进一步地，上述任一种实现方式中，测量支架还可包括挂载件，安装梁32上沿安装梁32的长度方向设置滑动轨道，挂载件滑动连接于滑动轨道，标定元件400通过挂载件安装于安装梁32，以使标定元件400可通过滑动导轨相对于安装梁32滑动，以适应不同的待标定设备，所述待标定设备可以是自适应巡航系统的传感器，例如：夜视系统的传感器，车辆偏离警示系统的传感器等，而不同系统的待标定设备其在车辆上的位置是不相同的，例如：夜视系统的传感器一般在车头偏离中点的位置上，自适应巡航系统的传感器一般在车头两侧。在一些实施例中，所述安装梁32可相对所述支撑架31转动，以调节所述安装梁32的俯仰角度，使安装梁32上的标定元件朝向车辆的面与地面垂直，保证了标定元件的定位精度，进而保证了车辆标定的精度。

在本实施例中，所述支撑架31为“V”字型结构，所述支撑架31与所述安装梁32围合形成三角形架构，以使得所述安装梁组件30在移动或转动的过程中能保持相对稳定的状态。
在其他一些实施例中，所述支撑架也可以为“工”字型或“U”字型等结构，对此本申请不作任何限制。
由于测量支架100在应用到轮定位时，需要支架稳定，在应用到挂载标定元件时，需要支架可移动，以适用于不同的车型，定位于相对于车辆的不同位置。对此，可以在底座的底端设置有可移动结构，以满足测量支架100相对于车辆移动进而定位至指定或预设位置，并在地面上设置限位紧固机构，以使底座相对于地面固定以满足测量支架100被应用做轮定位支架时保证测量支架的稳定性。或者，底座被设计为相对于立架组件是可拆卸的，底座在应用到挂载标定元件时，即可相对于地面移动，在应用到轮定位时，底座可被卸载，立架组件直接固定于地面的某一处，这样即可方便测量支架100的安装与运输，也可满足两种场景下的不同需求。

在一些实施例中，安装梁可相对于支撑架31沿竖直方向移动，即实现挂载在安装梁32上的标定元件和/或轮图像采集组件的高度调节。其中，支撑架31上可安装导轨或者安装座，用于将安装梁设置在不同高度上，具体实现方式本申请不予限定。
在一些实施例中，安装梁组件30仅可绕转动轴线O相对于立架21转动，当所述支撑架绕转动轴线O的转动不通过旋转电机止动时，请参阅图5，所述测量支架100还包括锁紧结构50，所述锁紧结构50用于在所述支撑架31绕所述转动轴线O转动至一个位置时相对于所述立架21固定所述安装梁组件30。
所述一个位置是指安装梁32处于水平横向的位置，且挂载于安装梁组件30上的标定元件和/或轮图像采集组件正对车辆。在本实施例中，所述锁紧结构50包括连接板51，螺栓52和螺母53，所述连接板51的一端连接所述支撑架31，所述连接板51的另一端向所述立架21延伸，所述连接板51靠近所述立架21的一端设置有供所述螺栓52穿孔的孔，所述立架上设置有与所述螺栓52相配合的滑槽211，所述滑槽211沿竖直方向设置，在所述安装梁组件30绕所述转动轴线O转动至所述位置时，所述螺栓52依次穿设所述滑槽211和所述孔后与所述螺母53螺纹紧固连接。可以理解，在所述螺母未拧紧时，所述螺栓52可沿所述滑槽211移动。

在一些实施例中，由于安装梁32需承载标定元件400及轮图像采集组件， 锁紧结构50无法保证安装梁组件30与所述立架组件20的稳定连接，为提高测量的精准性，所述测量支架还包括紧固结构60，所述紧固结构60用于在所述锁紧结构50相对于所述立架21固定所述安装梁组件30时，连接所述安装梁组件30和所述立架组件20，以使所述安装梁组件30和所述立架组件20连接紧固。

请参阅图7，在一些实施例中，为进一步增大安装梁32高度调节的范围，所示安装梁组件30还可沿竖直方向相对于立架21移动，具体地，所述立架组件20还包括驱动机构22，所述驱动机构22用于驱动所述安装梁组件30沿竖直方向相对于所述立架21移动，所述安装梁组件30沿竖直方向的移动机构可以通过任何常规手段进行，例如滑轨和滑块的组合、齿轮传动机构、丝杆传动机构等。用于驱动安装梁组件30沿竖直方向移动的机构可以被手动致动，或者可以由操作者手动控制或者自动软件控制下由合适的电机驱动。在一些实施例中，支撑架31于立架组件20之间的转动机构40与驱动机构22分离，即转动机构40与驱动机构22之间无连接关系，支撑架31有条件地实现相对于立架组件20沿竖直方向移动。第一种情况，支撑架31处于立架组件20的上端时，如图1所示的支撑架31的位置，即支撑架31应用于轮定位情景，支撑架31相对于立架组件20固定，即支撑架31不能相对于立架组件20沿竖直方向移动。在此场景下，立架组件20还可以设置有辅助支撑部，用以辅助支撑架31支撑安装梁32，分担安装梁31的重量，保证安装梁32水平横向设置。其中，辅助支撑部的一端固定在立架组件20，辅助支撑部相对于立架组件20是可活动地，在支撑架31处于立架组件20的上端时，辅助支撑部的另一端连接安装梁32，用以支撑安装梁32。或者，立架组件20和安装梁32上设有连接部，在支撑架31处于立架组件20的上端时，辅助支撑部的两端分别连接立架组件和安装梁上设有的连接部，用以支撑安装梁，辅助支撑部的具体实现在此 不予限定。第二种情况，安装梁32处于支撑架31的下端时，如图4所示的支撑架31的位置，即安装梁32用于车辆标定场景，支撑架31与驱动机构22连接，进而通过驱动机构22驱动支撑架31相对于立架组件沿竖直方向移动，以使安装梁组件30在驱动机构22得驱动下沿竖直方向移动。在支撑架31由图1所示的位置通过转动机构40转动至如图4所示的位置后，可以释放支撑架31与转动机构40的连接关系，并使支撑架31与驱动机构22产生连接，进而可以实现驱动机构22驱动支撑架31相对于立架组件20沿竖直方向移动，例如，此时的转动机构为离合器。
在一些实施例中，支撑架31与立架组件20之间的转动机构40与驱动机构22连接，进而能够保证支撑架31实现相对于立架组件20沿竖直方向移动的同时，还能够实现相对于立架组件20转动。具体实现方式可参照下文描述。
可以理解，在支撑架31能实现相对于立架组件20沿竖直方向移动的同时，还能够实现相对于立架组件20转动时，上述的锁紧结构50及紧固结构60均需释放安装梁组件30与立架组件20之间的连接，以使安装梁组件能自由绕转动轴线O相对于立架转动。在本实施例中，所述驱动机构22包括驱动源221和传动组件，所述驱动源221通过传动组件连接于所述安装梁组件30，所述驱动源221用于驱动所述安装梁组件30相对于所述立架21移动。

对于通过一个锁紧装置同时实现支撑架的转动及支撑架沿竖直方向的移动，可采用上述的锁紧结构50，例如，在所述支撑架转动至所述位置时，将螺栓52依次穿过滑槽211及连接片上的孔，此时，与螺栓52配合的螺母53处于未完全拧紧的状态，此时，安装梁组件30无法绕转动轴线O转动，但可沿所述滑槽311移动，当所述安装梁组件30移动至所需位置时，拧紧所述螺母53，即可实现安装梁组件30沿竖直方向的锁紧，当需安装梁组件需继续沿竖直方向移动时，旋松所述螺母53即可。
对于分别通过两个锁紧装置分别实现支撑架的转动及沿竖直方向的移动，可采用一个锁紧装置实现支撑架转动的锁紧，例如可采用锁紧螺纹孔和锁紧螺栓的组合，在轴座42上开一个螺纹孔，在支撑架转动至所述位置时，将一个螺栓拧入轴座上的螺纹孔并与连接轴抵接，即可实现支撑架转动的锁紧，在安装梁组件移动至所需位置时，可采用类似锁紧装置50的结构实现安装梁组件沿竖直方向的锁紧，只是此时的连接板一端与螺母座223相连，另一端向立架21延伸，当所述安装梁组件30移动至所需位置时，拧紧所述螺母53，即可实现安装梁组件30沿竖直方向的锁紧，当需安装梁组件需继续沿竖直方向移动时，旋松所述螺母53即可。

在本申请实施例中，所述高度是相对于地面而言。所述第一高度范围为1100mm～2700mm，所述第二高度范围为300mm～1000mm。
可以理解，在一些实施例中，所述立架21的顶端和底端分别设置有限位装置，所述限位装置用于限制滑块的行程，以使所述安装梁能在第一高度范围 内沿竖直方向移动；所述立架上还设置有传感器，所述传感器用于使安装梁移动至距离所述地面预设距离处，从而使得所述安装梁能在第二高度范围内移动。
可以理解，所述预设距离可根据实际情况进行设定，预设距离的设置是为了防止安装梁在移动的过程中触碰地面或底座。
本发明提供的一种车辆测量设备，既可以实现对车辆的标定，也可以测量所述车辆的轮状态，通过配置支撑架，支撑架可绕转动轴线相对于所述立架转动，且安装梁连接于所述支撑架远离所述转动轴线的一端，可以使安装梁处于两个不同的高度，以分别满足标定设备和四轮定位仪设备对安装梁高度需求，方便快捷，且车辆测量设备占地面积小，测量精度高。
另外，在安装梁可沿竖直方向相对立架移动时，安装梁连接于所述支撑架远离所述转动轴线的一端，可以减小丝杆长度，节约成本。
本申请的车辆测量设备可以很好的满足ADAS标定设备的安装梁高度和轮状态测量的安装梁高度。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；在本发明的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本发明的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
