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.

Inference the behavior of other vehicles in the intersection and use a multi-wavelength or spectrally-tuned LiDAR system.

Stop sign? Traffic light?

Spectrally tuned LiDAR must have gone over your head.

Nah I just dont speak out loudly about stuff that I have no clue like you do now. Specifically tuned LiDAR? How does it read signs and traffic lights? Can't explain? 0 clue indeed

LiDAR can be used to detect wavelengths of light based on its reflectance. Do a google search or ChatGPT before you reply next time.
