Rodrigo F. Berriel, Andre Teixeira Lopes, Alberto F. de Souza, Thiago Oliveira-Santos

摘要:

高分辨率卫星图像越来越多地用于遥感分类问题。其中一个主要因素是这类数据的可用性。尽管如此,斑马线分类问题上的努力却很少。在这封信中,众包系统被利用,以使自动采集和注释的大型卫星图像数据库的人行横道相关的任务。然后,该数据集用于训练基于深度学习的模型,以准确地对包含或不包含斑马线的卫星图像进行分类。实验中使用了一个新的数据集,其中包含来自3大洲,9个国家和20多个城市的24万多张图像。实验结果表明,免费提供的众包数据可以用来准确地(97.11%)训练强大的模型,以执行在全球范围内的人行横道分类。

英文摘要:

High-resolution satellite imagery have been increasingly used on remote sensing classification problems. One of the main factors is the availability of this kind of data. Even though, very little effort has been placed on the zebra crossing classification problem. In this letter, crowdsourcing systems are exploited in order to enable the automatic acquisition and annotation of a large-scale satellite imagery database for crosswalks related tasks. Then, this dataset is used to train deep-learning-based models in order to accurately classify satellite images that contains or not zebra crossings. A novel dataset with more than 240,000 images from 3 continents, 9 countries and more than 20 cities was used in the experiments. Experimental results showed that freely available crowdsourcing data can be used to accurately (97.11%) train robust models to perform crosswalk classification on a global scale.
