Definitions
- the invention relates to the technical field of blind indoor positioning, and in particular to an indoor positioning system for a blind population.

Description
本发明涉及盲人室内定位技术领域，具体地，涉及一种针对全盲人群的室内定位系统。
盲人就是眼睛患有疾病或受到意外伤害而导致双目失明或单目失明的人，盲人分为先天盲人与后天盲人之分。根据世界卫生组织的估计，全世界有盲人4000万到4500万。我国8300多万残疾人中，视力残疾人1233万，盲人约500万，是世界上盲人人口最多的国家之一。如何解决他们正常学习、工作和生活问题成为社会关注的焦点。
视觉障碍是由于先天或者后天原因致使视觉系统部分或全部丧失功能,以致无法对外界事物进行准确辨识。依据相关规定，视觉未达0.3，或视野在20°以内者即为视觉障碍。根据障碍程度不同，视觉障碍可以分为两类:两眼视力测定值在0.03以上未达0.3或其视野在20°以内为弱视；两眼视力测定值未达0.03为全盲。弱视人群通常可以利用视觉进行日常生活，但是在视物方面有一定障碍，一般需要借助光学辅助设备或特殊放大设备来观察事物。
全盲人群完全不能依赖视觉进行日常生活，通常只能采取替代方式进行日常生活。例如，利用触觉辅助设备、听觉辅助设备和其它类型辅助设备来替代视觉。大多数信息无障碍技术和设备都可以应用于全盲人群。几乎所有的视力残疾人都可以通过辅助器具补偿功能，不同程度地提高生活质量，参与社会生活。然而，第二次抽样调查显示，我国的视力残疾人中获得辅助器具服务的仅占7.97％；其中城市14.49％，农村5.82％。
可穿戴引导设备是指可以通过对于穿戴者周围环境的检测与数据分析提高其在复杂环境中的即使是不接受视觉信息的情况下依然能够应对各种情况的辅助设备。由于全盲人群的特殊性，针对全盲人群的可穿戴引导设备应当属于非视觉助视器，充分利用视觉以外的功能，如听觉、触觉等功能来弥补视觉功能的缺陷从而提高视障者生存质量的辅助器具，涉及到全盲人群生活、工作、学习、娱乐等的方方面面。例如：用于日常生
活的盲用手机和电话、发声钟表；用于出行的盲杖、盲道；用于学习交流的盲文、点显器、有声读物、各种读屏软件等。
由于盲人的特殊性，针对盲人的室内定位系统实现起来非常困难，由于可穿戴引导设备的引入，使得我们有希望做出一个针对全盲人群的室内定位系统。
综上所述，针对全盲人群的室内定位系统对于全盲人群的生活、工作有重要意义。现有的种类繁杂的室内定位系统不适用与盲人这个特殊的群体，对于盲人来说，不符合易用、适用、简单便携、可扩展等原则。

为实现以上目的，本发明提供一种针对全盲人群的室内定位系统，包括：可穿戴的引导设备和含有一系列特定信息的定位标签，可穿戴引导设备检测遍布于室内各处的定位标签并且提取出定位标签中含有的特定信息，并将信息传递给盲人，从而实现室内定位与引导的功能。

进一步的，所述图像采集设备是对穿戴者正面进行采集，或者对穿戴者全方位各个视角进行采集；如果是全方位各个视角进行采集，在数据处理中心将全方位视角的图像进行图像拼接，形成全景图，或者不进行拼接，将各个视角的图像分别存放。
