Description

On the [website](https://level5.lyft.com/dataset/download-dataset/), the LiDAR top view visualization sometimes do not match the RGB images.

Scene 4 for example:
In the beginning of the sequence, the RGB images show a lot of cars in front of the ego vehicle,
the LiDAR top view visualization does not show any.

Others seem to be mixed up, too.
I think Scene 4 visualization should probably belong to Scene 2 data and Scene 5 visualization should probably belong to Scene 4 data.

I hope it is just wrong on the website and not also mixed up in the training data.

Research direction

Start with the website's Scene 2, Scene 4, and Scene 5 visualizations and compare their RGB images with the LiDAR top views at the beginning of each sequence. Determine whether the mismatch is only in the website mapping or also in the training data; done means the affected scenes are correctly matched or the data issue is clearly documented.
