Data definitions and scope #75

Hi

Thanks for the comprehensive dataset I wanted to make sure that I understood the data provided.

In the LiDAR data there is an 'i' and 'd' value - I was thinking 'i' is the Identifier of the object but not sure if 'd' is a measure of distance since it has values from 0 to 1.

Also is there a chance to limit the LiDAR data to only what the front and back camera sees?

Thanks Amine

'i' means 'intensity' and 'd' means 'device' (0 means from Pandar64, 1 means from PandarGT) For limiting Lidar points you can see https://github.com/scaleapi/pandaset-devkit/blob/master/tutorials/projection/projection.ipynb
