The coordinate of the dataset

#10
by Doduchuy12 - opened

I have few questions about the coordinate of the dataset:

  1. What is the origin of the world coordinate in the top down map of the floor (in pixel)?
  2. How can I project an object in the world coordinate (meters) in the ground truth file into the pixel coordinate of the file top down map (map.png) in the data?
  3. What does the cameraMatrix mean in the calibration.json file?. It is not equal to intrinsicMatrix.dot(extrinsicMatrix)
