具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例，本领域技术人员可以想到其他显而易见的变型。在以 下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
如图1至图16所示是根据本发明的一个优选实施例的手势识别模组测试机器及其应用的示意图，所述手势识别模组测试机器包括箱体10，驱动装置20，测试标板30，模组定位装置40，以及滤光器50。
所述箱体10提供用于测试的容纳腔11，在本发明的这个优选实施例中，所述容纳腔适合是密闭性的容纳腔，从而在测试时不受到外部环境的影响。也就是说，所述箱体10优选是全封闭的，从而防止外部因素影响所述容纳腔调11内部的测试。
具体地，作为一个例子，所述箱体10可以是规则的方形的测试箱，其包括底壁，四个周壁，以及顶壁，所述底壁，四个周壁以及所述顶壁界定所述容纳腔11。当然，本领域技术人员可以理解的是，所述箱体10也可以有其他形状和构型，其只要能够提供适合用于测试的所述容纳腔11即可，本发明的这方面并不受到限制。
所述箱体10提供全黑的环境，方便测试，其材料需要使所述箱体10不透光，在一个优选的例子中，所述箱体10由黑色电木(酚醛塑料)制成，并且在所述箱体10的内壁还设置有一层吸光层，用于在测试时吸收额外的杂光。更具体地，所述吸光层可以是由丝绒材质制成，其贴附于所述箱体10的内壁，从而不会使所述容纳腔11内的光产生反射而影响测试。
所述测试标板30用于提供测试的标板图案，从而评估待测的手势识别模组M。在本发明的这个优选实施例中，所述测试标板30包括LED灯板31，其可以由多个LED灯311组成LED灯阵列，所述LED灯板31产生的多余杂光会由所述吸光层吸收，从而不会影响最终的测试。
所述测试标板30安装于所述驱动装置20，所述驱动装置20用于带动所述测试标板30往复运动，从而调节所述测试标板30与所述手势识别模组M之间的距离。在本发明的这个优选实施例中，所述测试标板30适合于在所述容纳腔调11中上下运动，从而方便于对所述手势识别模组M进行相关的测试。
值得一提的是，传统测试方法中，通过光源照射标板纸来提供用于测试的标板图案，而在本发明中，所述测试标板30本身由LED灯311组成，从而所述 LED灯阵列既提供了光源，又同时提供了标板图案。当然，根据不同待测模组的要求，本发明中的所述测试标板30也可以根据实际需要进行更改。
所述测试标板30可以用于手势识别模组M的光晕测试等，并且所述测试标板30可以在所述驱动装置20的作用下移动以离开或靠近所述手势识别模组M从而调节所述测试标板30与所述手势识别模组M之间的距离，以用于对所述手势识别模组M进行校准。
所述滤光器50用于过滤所述LED灯31形成的所述测试标板30投射向所述手势识别模组M的光线，以得到均匀光源。在本发明的这个优选实施例中，所述滤光器50可以实施为散光板，其将进入所述散光板的光线经历折射、反射和/或散射后，调整光线的传播方向，从而使穿过所述散光板的光线得以均匀投射，从而所述滤光器提供了较佳的光扩散效果，以更方便测试。例如，更具体的例子中，商业上可获得的所述滤光器50可以是俄亥俄州克利夫兰市的Grafix Plastics公司的OptiGrafixTM散光膜产品。
本发明的优选实施例的所述手势识别模组测试机器可以适用所述手势识别模组M的多种测试，包括模组出图情况测试(Frame Test)，热噪点测试(Noise test,Sensor Test)，挡光块效果测试(漏光测试，Blocker Test)，模组上红外LED灯工作情况测试(LED Test)，均匀性测试(Uniformity Test)，光晕测试(Vignetting Test)，光斑测试(Glare Test)，模组校准(Calibration Test)，以及模组三维整体测试(Module Test)等。
在所述模组出情况测试中，可以测试所述手势识别模组M是否可以输出图像；所述热噪点测试用于测试感光芯片的热噪等级；在所述挡光块效果测试以及所述光斑测试中，可以测试挡光块以及透红外玻璃对应的光斑情况；所述红外LED灯工作情况测试可以测试感光芯片的LED灯的亮度以及视场；在所述光晕测试和均匀性测试中，可以测试模组光晕情况以及颜色的一致性；在所述模组校准测试中，可以对所述手势识别模组M进行调焦校准；在所述模组三维整体测试中，可以测试模组校准的效果。
另外，所述模组出情况测试，所述热噪点测试，所述挡光块效果测试，所述光斑测试中，所述红外LED灯工作情况测试，所述光晕测试和均匀性测试可以应用于任何类型的所述手势识别模组M。所述模组校准以及模组三维整体测试 需要针对特定的所述手势识别模组M设计测试算法。例如，在一个具体例子中，所述模组校准以及模组三维整体测试采用Leap motion算法，从而可以应用于对Leap motion体感产品进行测试，其测试方法在下文中将更具体地描述。
更具体地，参照如图3A至图14以进一步地描述本发明的所述手势识别模组测试机器。如图3A至图5B所示，所述模组定位装置40适合于可拆卸地安装于所述箱体10，以方便更换从而适合不同款式的所述手势识别模组M的测试，也就是说同样的所述手势识别模组测试机器可以应用于不同类型的模组的测试。
如图2中所示，所述箱体10设有模组安装口12，待测试的所述手势识别模组M适合于穿过所述模组安装口12进入所述箱体10内部，以进行后续相关测试。所述模组定位装置40包括定位主体41，其可以实施为延长形的板状或条状结构，所述定位主体41具有模组定位槽42以及测试线定位槽43，所述模组定位槽42用于放置所述手势识别模组M，所述测试线定位槽43用于放置测试线。值得一提的是，定位主体41的尺寸和所述箱体10的内部尺寸相匹配，所述定位主体41的尺寸可以略小于所述箱体10的内部尺寸，并且当所述定位主体41位于所述箱体10内时，所述定位主体41的端部最好密封所述模组安装口12，从而使所述箱体10的所述容纳腔11保持全黑环境。
另外，本领域技术人员可以理解的是，本发明的所述模组定位装置40也可以具有其他结构，其只要能承载待测试的所述手势识别模组M并且适合于放置在所述箱体10内以方便后续相关测试即可。
如图3A和3B所示，所述手势识别模组M可以是一体式产品，例如可以是安装有摄像头的能够独立完成手势识别的体感产品。所述手势识别模组M定位于所述模组定位槽42后可以通过推动所述定位主体41进入所述箱体10内部，所述定位主体41可以由所述箱体10的底壁进行支撑。所述模组定位槽42的设置可以避免所述手势识别模组M放置于所述模组定位装置40后产生晃动而影响测试结果。位于所述测试线定位槽43的测试线用于将所述手势识别模组M与其他外部控制设备相联接并传送操作指令和数据。
所述模组定位槽42的尺寸与一体式产品的所述手势识别模组M尺寸相匹配，例如所述手势识别模组M可以与所述模组定位槽42周围的周壁过盈配合，从而使所述手势识别模组M得以稳固地安装于所述模组定位槽42。另外，所述模组 定位槽42的深度可以略小于一体式产品的所述手势识别模组M的厚度，这样通过握持于一体式产品的所述手势识别模组M两侧，可以方便地将其安装于所述模组定位槽42，对应地，当需要取下一体式产品的所述手势识别模组M时，也可以通过握持一体式产品的所述手势识别模组M的暴露在所述模组定位槽42的边缘，然后施加拉力以取下所述手势识别模组M。
如图4A和图4B所示，所述手势识别模组M可以是单纯的双摄像头模组M’,其可以是从模组生产线上取下来的双摄像头模组，经过测试以后再用于制造最终的手势识别产品。相应地，所述模组定位装置40’的所述定位主体41’模组定位槽42’，测试线定位槽43’，以及多个定位元件44’，对应地，所述双摄像头模组M’具有相应数量的定位孔，以与所述定位元件44’相配合，从而进一步地确保所述双摄像头模组M’在测试时不会晃动和偏移。
也就是说，在本发明的这个优选实施例的变形实施方式中，进一步提供了将所述双摄像头模组M’进行稳固定位并且方便拆卸的结构，其可以是上述定位元件43’与对应的定位孔之间的可拆卸配合，所述定位元件44’可以呈柱状，条状，片状等形状，其可以设置于形成所述模组定位槽42’的底壁和/或侧壁。本领域技术人员可以想到的是，所述双摄像头模组M’也可以与所述模组定位装置40’的所述定位主体41’通过其他结构来实现定位效果。
如图5A以及图5B所示，所述手势识别模组M也可以是单摄像头单元M”，两个所述单摄像头单元M”配合可以形成双摄像头模组。所述手势识别模组可以对各个所述单摄像头单元M”进行测试。在图中所示的例子中，所述模组定位装置40”包括定位主体41”，其形成有模组定位槽42”，测试线定位槽43”，以及取放槽45”，所述取放槽45”与所述模组定位槽42”相连通地布置，并且交叉成形。具体地，如图5B中所示，所述模组定位槽42”沿着所述定位主体41”的长度方向形成，所述取放槽45”沿着所述定位主体41”的宽度方向形成，也可以说所述模组定位槽42”沿着纵向方向排列，所述取放槽45”沿着横向方向排列，从而所述模组定位槽42”和所述取放槽45”互相垂直并且相交地设置。从而在所述单摄像头单元M”完成测试后，操作者可以通过所述取放槽45”方便地将所述单摄像头单元M”取出。
值得一提的是，所述模组定位槽42”两侧都形成有所述取放槽45”，从而在 所述单摄像头单元M”完成测试后，可以通过将手或夹持设备放置于两侧的所述取放槽45”中，以抓持所述单摄像头单元M”并将所述单摄像头单元M”从所述模组定位槽42”中取出。另外，可以理解的是，所述取放槽45”也可以应用于上述双摄像头模组M’以及所述一体式产品的所述手势识别模组M的取放。
如图5B中所示，所述模组定位装置40”也包括至少一定位元件44”，对应的所述单摄像头单元M”具有相应的定位销，所述定位元件44”与所述定位销相配合以可拆卸地并且稳固地定位所述单摄像头单元M”。值得一提的是，所述模组定位装置40”可以形成有多个所述模组定位槽42”，从而所述手势识别模组机器可以同时对多个所述单摄像头单元M”进行测试。所述模组定位槽42”和所述测试线定位槽43”也可以一体形成，并且具有相同的尺寸。
如图6以及图9A至图11所示是根据本发明的优选实施例的所述驱动装置20的一种实施方式的结构示意图。所述驱动装置20包括驱动主体21以及控制系统22和必要的电源供应系统等，在本发明的这个优选实施例中，所述驱动装置20可以实施为气压驱动装置，当然本领域技术人员可以理解的是，所述驱动装置20也可以是其他可以将所述测试标板30进行往复移动的驱动系统，如液压驱动系统，电磁驱动系统等。
如图6中所示，所述驱动主体21是气缸装置，其具有导槽212，并包括设置于所述导槽212中的活塞213，以及耦接于所述活塞213的驱动器214，所述测试标板30进一步包括标板定位装置32，所述标板定位装置32安装于所述驱动器214。从而当所述导槽212中气体的作用而驱动所述活塞213往复运动时，耦接于所述活塞213的所述驱动器214对应地往复运动，从而使安装于所述标板定位装置32的所述LED灯板31相应地往复运动以调节所述LED灯板31与所述手势识别模组M之间的距离，从而满足相关测试的需要。
值得一提的是，为了更好地保证所述箱体10内的全黑环境，所述驱动器214，其可以作为气缸行程块，由亚光材料制成，并且表面进行发黑处理。并且如图2中所示，其示意了所述驱动器214在上下极端位置，在所述上下极端位置之间和距离即所述驱动器214的行程，相应地，其也定义了所述测试标板30的行程。
另外，如图2所示，所述箱体10还包括定位板13，其横向地设置于所述容纳腔11中，并且所述定位板13中心的位置形成有开口14，所述驱动器214能 够到达的最下端的位置不会越过所述开口14，即所述驱动器214能够到达的最下端的位置高于所述开口14，从而在测试时，所述测试标板30的所述LED灯板发出的光线只能通过所述开口14进入所述手势识别模组M，而其他的额外光线由所述定位板13阻挡或吸收，以提高测试精度。
在图6所示的驱动主体21的结构中，所述驱动器24可以通过机械结构连接于所述活塞23。当然，所述驱动主体21也可以有其他多种结构。如图8和图9所示，其示意了不同的气缸驱动结构。图6和图7所示的是无杠气缸装置，而图8中示意了有杆气缸装置。
更具体地，如图7中所示，所述驱动器214’可以实施为磁环套，所述活塞213’上形成有内磁环215’，磁力线通过薄壁缸筒与套在外面的所述磁环套作用，并且所述内磁环与所述磁环套磁极相反，具有较强的吸力，当所述活塞213’被气压推动时，在磁力的作用下，带动位于所述缸筒外面的所述磁环套运动。也就是说，在这个变形实施方式中，所述驱动器214’与所述活塞213’并不是机械接触结构，而是通过磁性力耦接。
如图8中所示，所述驱动主体21”也可以是有杆气缸。更具体地，所述驱动主体21”包括活塞213”以及连接于所述活塞213”的活塞杆216”，所述活塞213”运动时直接带动所述活塞杆216”产生位移。所述活塞杆216”进一步地与所述测试标板30安装在一起，从而带动所述测试标板30产生位移。
值得一提的是上述驱动主体21的结构只作为举例而并不限制本发明，所述驱动主体21也可以是其他可以驱动所述测试标板30运动的驱动结构。在上述气缸式驱动主体结构中，为了节省空间，优选使用无杆气缸结构。
如图9A至11所示，其示意了本发明的这个优选实施例的控制系统22的结构，在所述驱动主体21是气缸结构时，相应地，所述控制系统22是气压控制系统，其包括气体控制阀221，气压平衡器222，气压调节阀223，以控制电路224。
更具体地，所述气体控制阀221用于控制气体的进出，从而控制所述活塞213的升降，从而最终控制所述测试标板30的升降。所述气体控制阀221可以是电子阀。
所述气压平衡器222用于确保进入所述驱动主体21内的气压是稳定的，从而进一步地确保气缸行程块是匀速升降，从而相应地使所述测试标板30得以匀 速升降。
所述气压调节阀223通过调节气压以控制升降速度的快慢，其相应可以设置上升速度控制旋钮2231以及下降速度控制旋钮2232，如图9D中所示。
如图10和图11显示了所述控制电路224的结构，其进一步地实施为继电器，所述控制电路224进一步地可通信地联接于控制主体如电脑，以控制所述驱动主体21的操作以及可以控制所述测试标板30中的所述LED灯板31的所述LED灯311的亮暗程度。作为具体的一个例子，所述继电器型号可以是Phidget Interface Kit 0/0/4 P/N:1014_2。
如图12所示是本发明的优选实施例的滤光器50的结构示意图，对应地，所述箱体10还设置有滤光器安装口15，所述滤光器50适合于可滑动地藉由所滤光器安装口15进入所述箱体10的所述容纳腔11，或移出所述箱体10的所述容纳腔11。相应地，可以理解的是，所述箱体10内可以设置滑动槽，所述滤光器50的边缘可以在所述滑动槽中滑动，从而可以方便取放和所述滤光器50在所述箱体10内的定位。
所述滤光器50可以实施为板状结构，用于过滤所述测试标板30的所述LED灯板31照射下来的光，从而得到均匀光源。在测试中，所述滤光器50位于所述测试标板30与所述模组定位装置40之间。更具体地，在本发明的这个优选实施例中，当所述滤光器50和所述模组定位装置40分别通过所述箱体10的所述滤光器安装口15和所述模组安装口12进入所述箱体10的所述容纳腔11后，所述滤光器50位于所述模组定位装置40的上方，以使所述测试标板30的所述LED灯板31发出的光线经过所述滤光器50的过滤作用后，再到达所述定位于所述模组定位装置40的所述手势识别模组M。
如图13所示是本发明的优选实施例的所述测试标板30的所述LED灯板31的结构示意图，其示意了多个所述LED灯311组成一个LED阵列。所述测试标板30安装于所述驱动主体21，从而得以上下运动，以方便对所述手势识别模组M的测试。
值得一提的是，根据不同所述手势识别模组M的测试要求，可以更换相应的所述测试标板30的所述LED灯板31，以满足不同的测试要求。也就是说，本发明这个优选实施例的所述LED灯板31及其所述LED灯311的排列方式只 作为举例，本发明并不受限于上述LED灯板31的形式。
下面，将具体描述本发明的手势识别模组测试机器用于具体的所述手势识别模组M的测试过程。所述手势识别模组测试机器可以与处理设备如控制电脑搭配以完成各项测试，控制电脑可以输入相应的控制信息以执行相应的测试步骤，并且所述控制电脑具有显示器，以用于显示测试结果。

具体地，下面将描述本发明的优选实施例对一种Leap Motion模组的测试过程。首先，手势识别模组M通过测试线与控制电脑相联接。显示器会显示“黑色遮幕”的指令。操作者可以将黑色物品平整地放置在所述手势识别模组M的表面，并且确保黑色物品与所述手势识别模组M紧密接触。在这个步骤中，可以完成模组出图情况测试，热噪点测试，挡光块效果测试(漏光测试)，光斑测试等，从而完成对所述手势识别模组M的基本功能情况的测试。
上述测试通过后，然后所述显示器显示指令“降低驱动器，放入滤光器，滑动手势识别模组M”。操作者将所述驱动器214降低至最低位置，此时测试标板的LED灯处于未打开状态，然后滑动所述滤光器50，以使所述滤光器50进入所述箱体10，并取下上述步骤中覆盖所述手势识别模组M的黑色物品，载有所述手势识别模组M的模组定位装置40放在所述箱体10中。然后在这个步骤中可以完成所述手势识别模组M上红外LED灯工作情况的测试。
上述测试通过后，所述显示器显示指令“打开LED灯板”，操作者开启所述测试标板30的所述LED灯板31，从而进行光晕测试，并检测镜头是否是尘埃颗粒等。
进一步地，所述显示器显示指令“取下滤光器，升高驱动器”，操作者将所述滤光器50取出所述箱体10，然后将所述驱动器214升高至最高位置，在这个过程中，所述测试标板30可以向上移动，从而改变所述LED灯板31与所述手 势识别模组M之间的距离，从而在这个过程中，可以对所述手势识别模组M进行校准。
然后针对所述Leap motion手势识别模组M，所述显示器进一步显示指令“关闭LED灯板”，后续继续进行三维整体测试。下面，将介绍所述Leap motion手势识别模组M的校准和三维整体测试的基本原理。
在所述校准测试中，所述测试方法包括如下步骤：

(e)通过比较这个过程中左侧图像和右侧图像，判定所述LED灯311的坐标是否在标准误差范围内，如果在标准之内，则所述手势识别模组M通过所述校准测试，如果没有在标准之内，则所述手势识别模组M不能通过所述校准测试。
在所述模组的三维整体测试过程中，其测试包括如下步骤：
(A)在所述箱体10内贴附预定数量的标记；
(B)经过所述校准测试的所述手势识别模组M照射所述箱体10内部，并输出测试图像；
(C)比对所述箱体内10所述标记的测试图像，判定所述手势识别模组M三维整体效果是否符合要求；以及
(D)如果上述测试未通过，则再对所述手势识别模组M进行一次所述校准测试。
在所述箱体10内，所述标记条可以根据需要进行设置，例如可以顶部2条白条，左右各1条白条，各个白条的宽度可以为10mm。
如图15所示，根据本发明的这个优选实施例，顶部2条白条可以贴附于所 述箱体10的顶壁，各个白条分别位于所述驱动装置20的两侧，各个白条的两端与所述箱体10的侧壁的距离是8.5cm，其外侧与所述箱体10的侧壁距离是5cm。
