Lane Change Classification and Prediction with Action Recognition Networks
Anticipating lane change intentions of surrounding vehicles is crucial for
efficient and safe driving decision making in an autonomous driving system.
Previous works often adopt physical variables such as driving speed,
acceleration and so forth for lane change classification. However, physical
variables do not contain semantic information. Although 3D CNNs have been
developing rapidly, the number of methods utilising action recognition models
and appearance feature for lane change recognition is low, and they all require
additional information to pre-process data. In this work, we propose an
end-to-end framework including two action recognition methods for lane change
recognition, using video data collected by cameras. Our method achieves the
best lane change classification results using only the RGB video data of the
PREVENTION dataset. Class activation maps demonstrate that action recognition
models can efficiently extract lane change motions. A method to better extract
motion clues is also proposed in this paper.Comment: Accepted by ECC
