TDA2P-ACD: Lane Detection with TIDL

Tobias Schulze

Part Number: TDA2P-ACD

Hi,

I'm trying to create an algorithm for lane detection/lane marking segmentation that is based on a deep learning model on the TDA2P EVM. I want to use the TIDL tools for converting my model and then integrate it into an existing PSDK use case (like tidl_OD). Unfortunately, the model I chose (https://github.com/MaybeShewill-CV/lanenet-lane-detection ) is not compatible with TIDL (unsupported topology/operators) and all other validated TIDL models are object detection or image classification.

Do you know some lane detection models that are compatible with TIDL?

Do you have any tips how I could implement such a model? I was thinking about using a semantic segmentation model that can detect lane markings and then process the output of that. But for that I would again need a SemSeg model that is compatible with TIDL...

Regards,

Tobias

Hi Tobias,

We validated TIDL with Semantic segmentation models, please find the pretrained models @ https://github.com/TexasInstruments/jacinto-ai-devkit

Thanks,

Hi Praveen,

thanks for your reply. The Semantic segmentation models only detect the road as one single "road" class, they don't differentiate between single lanes (e.g. the current lane where the vehicle is, the lane left of that etc.), right? That's what I'm trying to achieve.

Are there any TIDL compatible models that differentiate between single lanes? Or is there any trick to extrude those lanes from the existing SemSeg models?

Thank you,

Tobias

Hi Tobias,

No, you may have to train the model as per your requirement and mostly try to use layers supported by TIDL (refer to list of supported layers in TIDL Datasheet).

Thanks,

Praveen
