Hi Ronghe Qiu, here are my answers:
Thanks, Zhanteng.Do you also use the ground truth information of pedestrian during your training in gazebo.Only in sim-to-real experiment, since such oracle information is not available, the Yolo detector and MHT tracker is used. Such setting is manily to accelerate the training in simulator since with them the training is already quite slow. Is my understanding right? I think it is quite reasonable. The gap between ground truth and output from MHT tracker can be tolerate during the simulation training.
Can I also get the code about process images with Yolo detector and MHT tracker and then output the pedestrain map if it is convenient. That would help me a lot.
As shown in my paper, I used the YOLO & MHT pipeline to train the policy (trying to minimize the sim-to-real gap). However, since the preprocessing pedestrian map representation already bridges the sim-to-real gap well, using ground truth data is acceptable and speeds up training. If you want to further close the sim-to-real gap, you can add some noise to the ground truth data.
Sorry, we currently have no plans to open source the code for these hardware implementations, as they require some commercial license packages, which is a bit complicated. We will think about open sourcing them when we clean up these constraints and update the code. Thanks for your understanding.
Hi zhanteng, I would like to ask a question related to the pedestrian maps:
