在许多大中型城市，公共地图无处不在。人们还可以在公园或远足径附近找到大量的地图。公共地图有助于促进方向，并提供特殊信息，不仅为游客，但也为当地人谁只是想看看一个陌生的地方，而在旅途中。这些地图提供了许多优势相比，移动的地图服务，如谷歌地图移动的或诺基亚地图。它们经常显示标准数字地图上没有显示的当地地标和景点。通常，这些“你在这里”（YAH）地图适用于特殊用例，例如动物园地图或某个区域的徒步旅行地图。这些地图是为时尚目的而设计的，通常设计得很美观，因此它们的使用更令人愉快。在本文中，我们提出了一种新的技术和应用程序称为PhotoMap，使用的图像“你在这里”的地图与GPS增强的移动的相机手机作为背景地图上的飞行导航任务。我们讨论了主要挑战的不同实现，即帮助用户以足够的精度正确地对拍摄的图像进行地理参考，以支持行人导航任务。我们提出了一项研究，讨论了各种公共地图的适用性，这项任务，我们评估这些地理参考的照片，如果可以用于导航GPS功能的设备。
In many mid- to large-sized cities public maps are ubiquitous. One can also find a great number of maps in parks or near hiking trails. Public maps help to facilitate orientation and provide special information to not only tourists but also to locals who just want to look up an unfamiliar place while on the go. These maps offer many advantages compared to mobile maps from services like Google Maps Mobile or Nokia Maps. They often show local landmarks and sights that are not shown on standard digital maps. Often these 'You are here' (YAH) maps are adapted to a special use case, e.g. a zoo map or a hiking map of a certain area. Being designed for a fashioned purpose these maps are often aesthetically well designed and their usage is therefore more pleasant. In this paper we present a novel technique and application called PhotoMap that uses images of 'You are here' maps taken with a GPS-enhanced mobile camera phone as background maps for on-the-fly navigation tasks. We discuss different implementations of the main challenge, namely helping the user to properly georeference the taken image with sufficient accuracy to support pedestrian navigation tasks. We present a study that discusses the suitability of various public maps for this task and we evaluate if these georeferenced photos can be used for navigation on GPS-enabled devices.
