Project Description: | In order to create a seamless navigation solution for blind or visually impaired persons, the objective of this research is to assist a blind or visually impaired person in navigating through large unstructured environments that the person might encounter in the course of daily life: parks, parking lots, airports, sports arenas, intersections, and pedestrian zones in general. The research proposed here fills in the gaps where global positioning system (GPS) navigation is not sufficient. The full navigation system will integrate GPS, inertial measurement units (IMUs), and stereo visual odometry (SVO) to accurately capture the movements of the pedestrian user (direction and distance). In urban areas where GPS satellites are easily visible, commercial handheld GPS units provide a good navigation solution. Where some but not all needed GPS satellites are visible, situational awareness is further enhanced via implementing techniques in GPS-degraded positioning. Where GPS is not available at all (including indoor environments), IMUs and SVO provide sufficient positioning accuracy. Wireless information from pedestrian signals further enhances safety and mobility for the blind or visually impaired pedestrian. | |
