How to make 4 lane annotations to my own dataset's lanes

[daeunni]

Hi, thank you for your nice work! I confirmed that the lane annotation of CULane consists of 4 (left-left, left-right, right-right). Therefore, it seems that CULane has already been annotated with four lanes accordingly.

btw, I would like to apply it equally to my dataset. I have a binary segmentation for lane, then how can I generate the format of 4 annotations of CULane?

Tell me how plz
