Can your model also detect floors below the ground? (e.g. steps and stairs)

Hi there! I was searching for ground detection / height detection methods in autonomous driving for inspiration to develop cliff detection models. It seems like your model can detect whatever is above the ground but I was wondering whether your code can also perform ground depression (the opposite of elevation) and detect objects below the ground, like cliffs, steps and stairs (downwards). Thank you!
