Collecting detection velocities #19

Closed NithinDonepudi closed 11 months ago

NithinDonepudi commented 11 months ago

Hello, ZOD developers! I was hoping you could help me understand if it was possible to obtain velocities for the detected vehicles around the ego vehicle in each frame. Based off of my understanding, detection velocities are not provided by default, neither is the data sequential, to attempt manual calculation.

Unfortunately, there is no straightforward way to do this.

For single frames you have access to surrounding lidar scans, which could be used to estimate the new positions of a given object (for example using some tracking method). For sequences you have access to both surrounding lidar and camera so you could do the same. But there is no way to simply compute the velocities from the available information.

We are hoping to release sequence annotations in the future, but we have no time estimate for this.

Thanks for getting back to me, I guess i'll see what I can do!
