R00 Coordinate

[lacie-life]

Thank you for your great work. I am trying to use R00 set for object detection and I found that have some problems with the label. I some label files, the object orientation :

"orientation": { "rotationYaw": 3.14, "rotationPitch": 0, "rotationRoll": 0 }
and like that in R00/a9_dataset_r00_s03/_labels/1607434806_258307000_s50_lidar_ouster_south.json
"orientation": { "rotationYaw": 0, "rotationPitch": 3.14, "rotationRoll": 0 }
I quite confuse about this coordinate. So what is exaclty coordinate for R00 set?

Thank you !!!!
