[ros-users] [Discourse.ros.org] [Computer Vision / Perception] Avoiding Small Obstacles on the Gruond

[Daniel Snider ツ]

Just an idea: if you could try to establish a known colour or texture of the floor using computer vision then avoid anything that doesn't look like the floor. That's what I do when I walk cautiously.

Probably the most robust floor detector for a "very unstructured environment" would be a CNN trained to segment floor vs not-floor. If you have the budget, one way to get a training dataset is to create one using amazon turk to manually label a lot of images. 

Here's a couple slides showing existing deep learning segmentation approaches and software that I think look promising.
