[bug] Depth camera sees through walls

See original GitHub issue

Under some conditions - bump into the wall and look diagonally, depth camera can see through walls. Look up and down are NOT used here.

How to reproduce:

python3 -m minos.tools.pygame_client --width 512 --height 512 --depth -s map --navmap --scene_ids 87f009ce2c904df0f0b75433611e74bf

That’s great! Let us know if you see other problems. Also make sure to set the noise: true to use the simple depth noise model. Feel free to also add your own noise models. 😃

@ducha-aiki The issue you were observing is due to the larger default near plane setting (0.1) of the depth sensor relative to the color sensor (0.001). Thanks for reporting this – it is indeed quite important to set the near plane distance to match. Cutting off for near and far depth distance thresholds can then be done in the noise model functions instead.
