下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
如图1～2所示，本发明提供一种无人监控自动视觉检测装置，包括检测面板、检测器2以及和检测面板相对设置的隔离墙3；
所述检测面板沿从人眼到检测面板的方向依次包括：液晶显示面板12、下偏振片13和背光源14；所述液晶显示面板12显示视觉显示图片；所述检测面板还包括无线信号接收器和处理器；
隔离墙3上设有无线信号发送器，所述无线信号发送器将采集到的测试者的视觉指示信号通过网络发送至无线信号接收器；
所述无线信号接收器将接收到的视觉指示信号发送至处理器，所述处理器对视觉指示信号进行处理，并向检测面板发送处理反馈；

其中，处理器对视觉指示信号进行处理，并向检测面板发送处理反馈，具体包括：
将当前接收到的视觉指示信号与预先存储的标准视觉检测信号进行比较，并将比较结果反馈至检测面板，并判断是否已完成了所有视觉显示图片的检测，若未完成，提供下一个视觉显示图片继续检测；若已完成，则提示完成检测操作，存储并输出检测结果。
其中，隔离墙3上设有触摸方向杆33，通过对触摸方向杆33的操作向无线信号发送器发送测试者的视觉指示信号。
优选地，所述隔离墙上设有声音传感器，通过对测试者的声信号的采集向无线信号发送器发送测试者的视觉指示信号。
优选地，所述检测器2集成在隔离墙3上，所述检测器2连接升降杆31，在升降控制器的作用下，所述升降杆31带动检测器2做升降运动。
其中，优选该检测器2为快门眼镜，所述快门眼镜上设有控制电源总开关K1以及两个选择性反转开关K2和K3，其中K2控制镜片G1，K3控制镜片G2，且K2、K3在同一时刻，其中一个是闭合状态，另外一个是断开状态，其控制电路如图3所示。
另外，测试者在检测视力的同时，还可以一并测试身高。如图4所示，在隔离墙的顶部设有至少一个图像采集模块34，用于检测测试者的身高，测试者5的身高的计算公式如下：
h2＝h1-(L2-d1 2)1/2
其中，h2为测试者的身高，d1为测试者与隔离墙的距离，h1为隔离墙上的图像采集模块(例如摄像头)的高度，L为通过图像采集模块34得到的图像采集模块34距离测试者头部的距离。
另外，在测试身高的同时，还可以同时一并测试体重，在隔离墙的底部设有体重感应器，用于检测测试者的体重。

参考图1为佩戴检测器状态下视觉检测装置的示意图，当视觉检测装置通电后，液晶分子将发生偏转，测试者佩戴检测器2后，即可以将视觉显示图片的内容反射出来，这样，只有佩戴检测器的测试者才能看见视觉显示图片中的内容。
测试者在佩戴检测器的状态下，根据指挥人的要求作出E的上下左右方向的独立判断，减少了外界信息源的输入。
为了防止测试者进行位置记忆，可随机改变每行图案E的现实方向，防止通过位置记忆进行作弊判断。
另外，还可根据画面显示亮度或画面的缩放比例，适时进行观察距离的调整，以满足实际观测需求。如在正常显示亮度下，可在5m处进行检测；在亮度降低一半时，可在2.5m处进行检测。
