摘要:

用于车辆定位的基于视觉的解决方案最近变得流行。我们采用基于图像检索的视觉定位方法。数据库图像与GPS坐标一起保存,并且检索到的数据库图像的位置用作查询图像的近似位置。我们表明,本地化可以通过描述符单独从语义分割的图像中提取。特别是当环境受到严重光照和季节变化时,它是可靠的。我们的实验表明,语义描述符的本地化性能可以提高到最先进的RGB图像为基础的方法的水平。

英文摘要:

Vision based solutions for the localization of vehicles have become popular recently. We employ an image retrieval based visual localization approach. The database images are kept with GPS coordinates and the location of the retrieved database image serves as an approximate position of the query image. We show that localization can be performed via descriptors solely extracted from semantically segmented images. It is reliable especially when the environment is subjected to severe illumination and seasonal changes. Our experiments reveal that the localization performance of a semantic descriptor can increase up to the level of state-of-the-art RGB image based methods.
