Method Description:
We propose PointTrackNet, an end-to-end 3-D
object detection and tracking network, to
generate foreground masks, 3-D bounding boxes,
and point-wise tracking association displacements
for each detected object. The network merely
takes as input two adjacent point-cloud frames.
Experimental results show competitive results in
the irregularly and rapidly changing scenarios.
Detailed in the paper.

Detailed Results

From all 29 test sequences, our benchmark computes the HOTA tracking metrics (HOTA, DetA, AssA, DetRe, DetPr, AssRe, AssPr, LocA) [1] as well as the CLEARMOT, MT/PT/ML, identity switches, and fragmentation [2,3] metrics. The tables below show all of these metrics.
