4Seasons Dataset

4Seasons: A Cross-Season Dataset for Multi-Weather SLAM in Autonomous Driving

We present a novel dataset covering seasonal and challenging perceptual conditions for autonomous driving. Among others, it enables research on visual odometry, global place recognition, and map-based re-localization tracking. The data was collected in different scenarios and under a wide variety of weather conditions and illuminations, including day and night. This resulted in more than 350 km of recordings in nine different environments ranging from multi-level parking garage over urban (including tunnels) to countryside and highway. We provide globally consistent reference poses with up-to centimeter accuracy obtained from the fusion of direct stereo visual-inertial odometry with RTK-GNSS.

For additional information, please visit the official 4Seasons-dataset webpage.

Dataset Tools

To make the work with our dataset as convenient as possible we are providing a collection of python tools in a GitHub repository.

This dataset is made available for academic use only. However, we take your privacy seriously! If you find yourself or your personal belongings in this dataset and feel unwell about it, please contact us 4seasons-dataset@artisense.ai, and we will immediately remove the respective data from our server.

We have been organizing workshops at international research conferences (i.e., ECCV, ICCV) to discuss the topic of map-based localization in autonomous driving with experts from industry and academia. In conjunction with the workshop, we are regularly organizing challenges based on the 4Seasons dataset.

French-German Machine Learning Symposium

French-German Machine Learning Symposium

The French-German Machine Learning Symposium aims to strengthen interactions and inspire collaborations between both countries. We invited some of the leading ML researchers from France and Germany to this two-day symposium to give a glimpse into their research, and engage in discussions on the future of machine learning and how to strengthen research collaborations in ML between France and Germany.

The list of speakers includes Yann LeCun, Cordelia Schmid, Jean-Bernard Lasserre, Bernhard Schölkopf, and many more! For the full program please visit the webpage.
