行人导航应用，尤其是室内导航应用需要以易于理解、记忆和遵循的形式来描述方式。虽然在室外车辆导航的情况下，以米为单位的距离加上转向提示是一个很好的描述，但这种描述对于室内区域来说毫无用处。行人对距离没有很好的了解，室内区域的转弯也并不总是明确的。地标似乎为这个问题带来了解决方案。在本文中，我们定义了一种识别相关地标的算法，以及一种使用位图平面图增强室内道路可视化质量的通用算法。这为自动生成具有不良可视化属性的路点图用于多媒体室内导航应用打开了大门。此外，算法在智能手机上实现，并给出了最终性能的结果。本文的主要贡献是将一些室内导航任务重新表述为图像处理任务。关键词-导航；图像处理；
Pedestrian navigation applications and especially indoor navigation applications need to describe a way in a form that is easy to understand, remember and follow. While in the case of outdoor vehicle navigation the distance in meter together with a turn hint is a good description such a description is merely useless for the indoor area. Pedestrians do not have a good understanding of distances and turns are not always well-defined in the indoor area. Landmarks seem to bring the solution to this problem. With this paper we define an algorithm to identify relevant landmarks and a general algorithm enhancing the visualisation quality of an indoor way using bitmap floorplans. This opens the door for automatically generated waypoint graphs with bad visualisation properties to be used for a multimedia indoor navigation application. Furthermore the algorithms are implemented on a smartphone and results on the final performance are given. The main contribution of this paper is the reformulation of some indoor navigation tasks as image processing tasks. Keywords-Navigation; Image Processing;
