Hi Eric,
Ouch, glass walls. No, unfortunately there isn't a lot that can be done with LIDAR sensors there. You can try to use
reflections to generate stereo data and hope for the best, but that's not going to work everytime. You are right,
employing sonars might help. Did you check the literature to see what other people are using to deal with glass?
Cheers,
Radu.
