In this paper, we present the application of an
RGB-D camera in developing a travel aid for the blind or visually impaired
people. The goal of the proposed travel aid is to provide the user with
information about obstacles along the travelled path so he or she may walk
safely and quickly in an unfamiliar environment. The performance of the travel
aid greatly depends on whether the ground plane can be successfully detected.
In this paper, we present a new approach to detecting the ground plane from a
depth image. Two different experiments were designed to test the performance of
the proposed travel aid.
