Question about GT_pose and Entity_ID #14

Open DanRos22 opened 4 years ago

DanRos22 commented 4 years ago

Thanks for this great dataset. I’ve downloaded the dataset and I have 2 questions:

  1. I try to match the Entity_ID label (from label_aug directory) with the color code in the segImage/instSegImage .png files. Is there any relation/equation between these 2 numbers?

  2. GT_Pose- Is there any recorded information about the egomotion. I.e. the relative 6DOF transformation between 2 consecutive camera positions?

Any answer/hint/code-reference would be helpful.

Hey - glad to hear you liked the dataset!

  1. The files in the instSeg directory have ints which correspond to the entityID. For instSegImage.png each instance is randomly coloured for visualization. You can take a look at m_pInstanceSeg in GTAV_ObjectDetection/ObjectDetection.cpp (submoduled from this repo) for details on how the instance segmentation is calculated.

  2. No there isn't any egomotion data available. I looked into creating a tracking dataset but I couldn't find a way to get consistent times between frames.
