Query: Relation3DMOT: Exploiting Deep Affinity for 3D Multi-Object Tracking
  from View Aggregation   Autonomous systems need to localize and track surrounding objects in 3D space
for safe motion planning. As a result, 3D multi-object tracking (MOT) plays a
vital role in autonomous navigation. Most MOT methods use a
tracking-by-detection pipeline, which includes object detection and data
association processing. However, many approaches detect objects in 2D RGB
sequences for tracking, which is lack of reliability when localizing objects in
3D space. Furthermore, it is still challenging to learn discriminative features
for temporally-consistent detection in different frames, and the affinity
matrix is normally learned from independent object features without considering
the feature interaction between detected objects in the different frames. To
settle these problems, We firstly employ a joint feature extractor to fuse the
2D and 3D appearance features captured from both 2D RGB images and 3D point
clouds respectively, and then propose a novel convolutional operation, named
RelationConv, to better exploit the correlation between each pair of objects in
the adjacent frames, and learn a deep affinity matrix for further data
association. We finally provide extensive evaluation to reveal that our
proposed model achieves state-of-the-art performance on KITTI tracking
benchmark.
