Tracking correspondence #171

Closed bilalsattar closed 4 years ago

bilalsattar commented 4 years ago

Following is written on the website:

We provide 2D bounding box labels in the camera images. The camera labels are tight-fitting, axis-aligned 2D bounding boxes with globally unique tracking IDs. The bounding boxes cover only the visible parts of the objects.

The following objects have 2D labels: vehicles, pedestrians, cyclists. We do not provide object track correspondences across cameras.

What does this means?

We do not provide object track correspondences across cameras.

It means images from different cameras (e.g. FRONT, FRONT_LEFT etc) are labeled independently. If an object appears in FRONT in t0 and appears in FRONT_LEFT in t0+delta, they will have different ID.

bilalsattar commented 4 years ago

but for benchmark, in 2d tracking, do you match tracks in individual cameras separately or the track is tracked across all cameras?

henrikkretzschmar commented 4 years ago

We evaluate the individual cameras independently in the 2D tracking challenge.
