Feature Request: Lines / Curves Annotations (Lane Lines)

[d4l3k]

Is your feature request related to a problem? Please describe.

Label studio doesn't have a way to draw lines of different types on the images. This would be very useful for things such annotating driving footage with lane lines of different types, road edges, etc.

Example from CLRNet: https://arxiv.org/pdf/2203.10350v1.pdf

Describe the solution you'd like

A new labeling task that allows selecting different types of lines (i.e. solid white, solid yellow, dashed yellow, dashed white, etc) and drawing them on the image.

Bezier curves would also be a nice feature to have but a multi segment line is likely sufficient

Describe alternatives you've considered

You can use segmentation for this but that produces a dense representation. A sparse representation for lane lines is often superior for planning tasks. I.e. Tesla is now using sparse representations for their lane graphs.

Additional context

Yes, agree that Lines / Curves annotation is a very useful feature. I'm wondering is there any progress in its implementation ?

+1 for this feature

[bhavik494tatva]

Need to draw line on image.

[jonasweihing]

That feature would be really great for our student research group. Without polyline labeling it is unfortunately a dealbreaker.

Would be awesome if we could get this.

[wangchenran]

This feature is great for me, can we do it ? I'm wondering is there any progress in its implementation ?

[abdelDarwish510]

Any updates on this?

Unfortunately there are no updates :-(

[doantientai]

Yes, that would be helpful for training contour detection models! Still waiting in 2024
