Question about the existence of lanes in tusimple and culane dataset

[solidexu]

The original dataset just supplies the coordinates of lane points. I wonder how we can determine which lane exists. I currently focus on another dataset which just have lane points info. Maybe I should relabel the existence info by myself or is there an another method to quickly identify the which lane existence and add the info into the train.txt?

@solidexu Existing datasets use line slope to determine existence. Note that existence is only needed for multi-class segmentation approaches (their seg label is also generated based on slope), the original script is cpp in https://github.com/XingangPan/seg_label_generate . You can refer to #40 for more discussions (Python scripts and such).

Thank you ~ I just found the C++ script from XingangPan. Using slope to determine the existence of lane is definitely a genius idea. But I am not sure if it works well with CurveLanes Dataset. Anyway, I will try it. Thanks again!

We also have problem doing this for CurveLanes, please share to us if you have a solution for this kind of dataset.

@voldemortX Hi, you mean we don't use lane existence label in train.txt (e.g. 1111) except segmentation-based model? :0

Yes. It is only meant for semantic segmentation.
