摘要
提出基于图像显著度和信息量均衡的地标链生成方法,该方法建立地标显著度、全景图信息量和地标切换次数的多目标模型,基于遗传算法生成多目标优化的地标链。实验表明,能较好地平衡地标显著度、全景图信息量及地标切换次数等优化目标,生成的地标链具有较高的显著度与较低的视觉认知负担。
The landmark sequence can provide a clear navigation clue in the process of pedestrian navigation. This paper proposes a method of the landmark sequence generation which based on the balance of image significance and information. This method builds a multi-objective model by the information of the panorama, the number of landmark switch and the landmark significance. And based on the genetic algorithm, the multi-objective optimization of the landmark sequence generation method is realized. Experiment shows that this method can balance the three optimization targets well: the landmark significance, the information of the panorama and the number of the landmark switch. Compared with other methods of the landmark sequence generation, this method has a high degree of the landmark significance, the low visual cognitive burden, and can reduce the number of landmark switch.
