参见图1和图2，所述检测机架包括：
横梁101、两个立柱102，两个立柱102分别通过调整块连接在横梁101两端，立柱102和横梁101之间还装设有斜撑103，用于支撑立柱102和横梁101的斜撑。
参见图2和图3，所述测量装置包括：
设置在立柱102和横梁101上的电缸104，电缸104的导轨上设置有可伸缩导杆105，可伸缩导杆105可在电缸104的带动下沿电缸104的导轨移动；
固定在可伸缩导杆105一端的连接板106，连接板106的一端设置有结构光107，另一端设置有工业相机108，工业相机108用于检测所述轨道车辆的外形轮廓，得到轨道车辆的截面轮廓数据。
优选地，结构光107可以是激光条。
本实施例中，PC机与电缸104的控制器相连，在进行轨道车辆限界检测时，待检测车辆驶入轨道车辆限界检测系统中的检测机架，PC机发控制指令给电缸104的控制器，电缸104的控制器接收到控制指令后控制电缸104工作，可伸缩导杆105在电缸104的带动下沿电缸104的导轨移动，靠近或者远离检测车辆。
需要说明的是，所述PC机中预先存入不同种类的轨道车辆的外形基准数据，进行轨道车辆限界检测时，所述PC机选取待检测车辆的外形基准数据，确定所述测量装置的移动方向，再发送相应的控制指令，控制电缸的控制器，并由其控制电缸工作，进而使可伸缩导杆运动，调整连接板的位置，以适应待检测车辆的测量要求。
测量所述待检测车辆时，所述结构光发射一条光束到待检测车辆，与所述结构光配套的工业相机拍摄带有光束的图像，并处理所述带有光束的图像，得到图像的三维信息。

最后还需要说明的是，本发明各个实施例公开的轨道车辆限界检测系统中，可以使用工控机作为PC机。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
