提出顾及地标与道路分支的行人导航路径选择算法。该算法能够利用地标降低导航路径的复杂程度,帮助视觉正常的行人确认当前位置以及是否偏离了当前路径。实验表明,本算法能够较好地平衡导航路径的三种优化目标:行程距离、路径复杂度以及路径地标数量。与最短路径算法相比,该算法选择的路径具有较低的复杂度与较高的路径地标密度。
A pedestrian navigation path selection algorithm that takes into account landmark and road branches is proposed. The algorithm can make use of landmarks to reduce the complexity of navigation paths and help visually-normal pedestrians to confirm the current position and deviate from the current path. Experiments show that the proposed algorithm can balance the three optimization objectives of navigation route well: travel distance, route complexity and number of route landmarks. Compared with the shortest path algorithm, the path selected by this algorithm has lower complexity and higher path landmark density.
