进一步优选地，功能单元包括定位单元4，所述定位单元4与中央处理单元1连接。此时，所述中央处理单元1根据从所述摄像头3接收到的路面以及周边环境信息以及在所述中央处理单元1的数据库中预存的路面以及环境信息进行比较和计算处理。所述定位单元4根据比较和计算处理的结果执行对当前位置定位的操作。也就是说可以通过定位单元4实现导航功能，使得盲人出行更加安全方便。优选地，在定位单元4对使用者进行导航的同时，定位单元所确定的位置还可以被存储为历史记录。例如，可以存储到设置在盲人眼镜上的存储单元中，或者通过无线的方式被发送并存储到远程计算机的内部存储装置中。通过这种方式，在使用者想要沿原路返回时，定位单元4可以通过参考历史记录的方式为使用者导航，从而无需再次通过中央处理单元1进行比较和计算处理。另外，当使用者的家属需要获知使用者当前所处的位置时，可以方便地通过操作上述远程计算机而得到相关信息。
本实施例的盲人眼镜优选的是，所述信号采集单元包括测距单元5，用于对周边环境中的目标物体进行测距，并将距离信息发送给 中央处理单元1。其中所述目标物体例如为路面上的障碍物、行驶中的车辆等等。
在上述实施方式的基础上，所述功能单元包括警告单元。所述中央处理单元1根据从所述测距单元5接收到的与目标物体之间的距离信息以及在所述中央处理单元1的数据库中预存的危险距离进行比较处理，并且所述警告单元根据比较处理的结果执行警告操作。具体地说，首先测距单元5感测使用者的当前位置与周边环境中的目标物体位置之间的距离，再将该距离信息发送给中央处理单元1。中央处理单元1将该距离信息与其数据库中预存的危险距离进行比较，如果比较结果为该距离小于危险距离，则中央处理单元1指示所述警告单元生成警告信息。所述警告信息可以通过例如音频播放单元(下文将描述)以声音的形式输出，也可以通过例如振动单元转换为使用者能够感知的机械振动输出。另外，警告单元还可以实现为以有效方式向作为目标物体的附近车辆发出警告的机构。例如，可以在该盲人眼镜中设置射频单元，当作为目标物体的车辆或其他物体中设置有与该盲人眼镜的射频单元相匹配的射频定位单元时，该车辆的驾驶者或持有相同射频定位单元的使用者也将接收到盲人眼镜的使用者的位置信息，从而可以及时躲避，避免危险的发生，进而可以提升盲人使用者在路上行走的安全性。
本实施中的测距单元5优选为采用多普勒效应的测距仪、超声波测距仪、红外测距仪、激光测距仪中的任意一种。
在本实施例中，盲人眼镜还包括音频播放单元，其设置在盲人眼镜的镜架上。所述音频播放单元根据所述中央处理单元1的指示用于将功能单元所执行的功能操作作为音频信息进行输出。例如说，定位单元4将当前位置与目标位置定位完成后，将该信息反馈给中央处理单元1，中央处理单元1指示音频播放单元开启，输出相应的语音信息以传递给盲人眼镜的使用者，也就是语音导航的功能。再例如，当警告单元执行警告操作时，可以将警告信息(警告内容)发送到音频播放单元，以通过音频播放单元输出为相应的语音信息传达给盲人眼镜的使用者。当然该音频播放单元还可以根据中央处理单元1的指 示输出乐音等语音信息。
本实施例的音频播放单元优选为骨传导耳机9，所述骨传导耳机9设置在镜架上，例如设置在镜架的镜腿上。骨传导耳机9可以避免外界噪音带来的干扰，同时也可以减少对公共场所下其他人员的干扰。另外，采用骨传导耳机9的方案可以确保盲人使用者准确及时获得信息，减少事故的发生。同时该耳机还采用弹簧伸缩的设计。当需要使用的时候直接拉镜腿上的耳机即可将耳机拉出到适当的长度，佩戴在耳朵上。当使用完毕后，耳机从耳朵上脱离的瞬间，将依靠耳机的弹簧线、耳机自动回复到眼镜腿上的耳机槽内。
本实施例的盲人眼镜还包括镜片，所述镜片上设置有太阳能供电单元6，所述太阳能供电单元6用于给信号采集单元、中央处理单元1、功能单元供电。在镜框上同样还可以设置蓄电池单元7，用于在无光照时为信号采集单元、中央处理单元1、功能单元供电。
本实施例的盲人眼镜的镜架上还设置有数据传输单元8，所述数据传输单元8可以用于与外接设备之间进行数据传输。该数据传输单元8包括wifi单元和/或蓝牙单元。例如，通过wifi单元可以实现中央处理单元1云端信息库之间的信息传输，实现更完善的处理功能和无线网络连接。通过蓝牙单元可以实现与外接设备的数据传输。使得本实施例的盲人眼镜更加智能化。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
