How to define a bbox in nav_task_relevant_object_bbox or nav_accurate_object_bbox?

Hello, I am currently trying to deploy PoliFormer in another simulator, and I have obtained the target object’s bbox in the format of (x, y, w, h). However, I am encountering difficulties when inputting this bbox into the model. I would like to ask how PoliFormer defines its bbox?

Additionally, I have an extra question: what is the difference between `nav_task_relevant_object_bbox` and `nav_accurate_object_bbox`, and how are they each obtained?

Thank you for your response.
