Position localization is essential for visually impaired individuals to live independently. Comparing with outdoor environment in which the global positioning system (GPS) can be utilized, indoor positioning is more difficult due to the absence of the GPS signal and complex or unfamiliar building structure. In this paper, a novel landmark-based assistive system is presented for indoor positioning. Our preliminary tests in several buildings indicate that this system can provide accurate indoor location information.
位置定位对于视障人士独立生活至关重要。与可利用全球定位系统（GPS）的室外环境相比，由于缺乏GPS信号以及建筑物结构复杂或不熟悉，室内定位更加困难。本文提出了一种新颖的基于地标的辅助系统用于室内定位。我们在几座建筑物中的初步测试表明，该系统可以提供准确的室内位置信息。
