The PREVENTION dataset: a novel benchmark for PREdiction of VEhicles iNTentIONs

January 2020

tl;dr: Dataset for cut-in and other lane-change prediction.

Overall impression

This dataset includes tracking and sensor fusion annotation.

Key ideas

High accuracy lateral movement of the vehicles are critical for the lane change prediction task. Symmetrically placed keypoints are traced (like BPE) automatically, with Median Flow. The tracking process is supervised.
Relative position of ego-vehicle wrt the road surface is useful to correct BEV pitch or height. The ground plane coefficients are computed with RANSAC with lidar point cloud.
Event types: Cut-in/Cut-out/Lane-change/zebra-crossing. Note: Cut-in and cut-out are actually not labeled. Only contains left and right lane changes.

Technical details

Cameras are externally triggered by lidar at 10 Hz.
On average, one lane change event in every 20 second.
Lane detection and tracking in BEV image with moving objects removed.

Notes

We need some metric to measure the prediction performance!
