Question regarding annotations (detection track)

While evaluating models I have encountered quite a few samples that I am having trouble with. One example is below.


Obviously everyone is equally impacted by the presence of images like this but out of curiosity are annotations like this incorrect or is this correct (based off of the spacecraft model)? I need to investigate quantitatively but with the naked eye there does not seem to be any signal that could facilitate the correct prediction of the true box (for the image above).

Hi @camhpj,

Good question. Yes, these annotations are correct, as they are based on 3D modeling in which the actual dimensions of the spacecraft and appendages are known. Some of the spacecraft have very long appendages, and will be difficult to model. It’s possible that no submissions will get them entirely correct. This is part of the challenge design – do your best!
