CaT: CAVS Traversability Dataset for Off-Road Autonomous Driving

Abstract: In the context of autonomous driving, the existing semantic segmentation concept strongly supports on-road driving where hard inter-class boundaries are enforced and objects can be categorized based on their visible structures with high confidence. Due to the well-structured nature of typical onroad scenarios, current road extraction processes are largely successful and most types of vehicles are able to traverse through the area that is detected as road. However, the off-road driving domain has many additiona… Show more

“…On the other hand, off-road environments contain challenging features such as changing terrain types and vegetation with complex geometry. Only a few datasets exists for off-road environments, which are RELLIS-3D, 10 ORFD, 5 and CaT; 30 and out of these, only RELLIS-3D offers labeled LiDAR data. Due to the challenge in annotating LiDAR datasets, some studies rely on simulations to generate labeled data.…”

“…The results of the potential traffic conflict analysis were utilized for road safety assessment, with special consideration given to CAVs based on insights provided by [45]. As is well known, potential traffic conflicts serve as the foundation for the application and modeling of the safety performance functions (SPFs), as elaborated in Section 5.…”

“…The sparse labeling greatly reduces the tedium seen in strongly-supervised methods, while enabling easy explicit labeling of untraversable regions and not requiring robot experience during training. Our method can also provide continuous predictions of traversability (rather than discrete classes [8]), and does not require the additional assumptions, data, or models needed in selfsupervised methods [4]- [7].…”
