如今，用于移动的电话的步行导航系统一般使用二维地图作为导航媒体。但是三维地图或风景图像比二维地图更容易被用户理解。使用三维地图或景物导航时，用户位置的测量精度对于理解导航图像至关重要。在本文中，我们将提出一个行人导航系统，使用真实的风景照片作为导航媒体，并根据实验，我们将报告的评估结果的定位精度对导航的可理解性的影响。结果表明，3米或更小的定位误差是可以容忍的行人导航系统使用风景图像。
Today, pedestrian navigation systems for mobile phones use 2-dimensional maps as a navigation media in general. But 3-dimensional maps or scenery images are easier to understand for users than 2-dimensional maps. To use 3-dimensional maps or scenery guidance, the measuring accuracy of user position is essential to understand guidance images. In this paper, we will present a pedestrian navigation system using real scenery photographs as a navigation media, and based on experiments we will report the evaluation result of influence of positioning accuracy on the understandability of navigation. It is shown that 3 meters or less error of positioning is tolerable for pedestrian navigation systems using scenery images.
