curvature estimation about lanedet

[Turoad]

Currently, this repo supports lane detection by deep learning, including both straight or curve lanes.

What's the curvature detection?

[k-nayak]

I wanted to know about the computation of curvature of the lane in real-time.

[Turoad]

curvature? Is this https://en.wikipedia.org/wiki/Curvature?

[k-nayak]

Yes. The plane curve. Kappa = 1/R

Kappa is curvature and R is the radius

I want to know if we can do curve fitting and get the curvature in using the robust lane detection of the model.

[Turoad]

Maybe you can try the curve-based method, like PolyLaneNet or LSTR. These methods predict the curve of lanes as a polynomial regression task.

I am trying to implement ultra fast lane detection model. And use curve base method to detect curvature. I will try lstr ans poly lanenet, if it doesn't work. Thanks for the suggestion.

If you are using UFLD, the curvature of lanes is calculated from post-processing?

[k-nayak]

Not really, I plan on using the traditional method of the perspective transform to BEV and calculating curvature using the detected lanes from the network.

[Turoad]

If so, I think you can also try other models like LaneATT (anchor-based method), RESA (segmentation-based method).
