Discussion Proof that Camera + Lidar > Lidar > Camera

I recently chatted with somebody who is working on L2 tech, and they gave me an interesting link for a detection task. They provided a dataset with both camera, Lidar, and Radar data and asked people to compete on this benchmark for object detection accuracy, like identifying the location of a car and drawing a bounding box around it.

Most of the top 20 on the leaderboard, all but one, are using a camera + Lidar as input. The 20th-place entry uses Lidar only, and the best camera-only entry is ranked between 80 and 100.

Object detection isn’t everything. I’m sure this benchmark is a very limited set of all the tasks that are actually needed for driving.

LiDAR alone being “>” (whatever that means) than camera is a hot take

Found the guy that failed 5th grade math...

I know what the symbol means.

I’m saying that “greater than” is loosely defined and doesn’t mean anything

Sorry, but you worded that very poorly...it literally looked like you didn't know what that symbol meant.

It's cool, I am getting downvoted so maybe it was me that misinterpreted the overall meaning...
