Abstract
In this research, we present a system that can support visually handicapped people to walk alone safely on tactile paving. The system can warn the user in the case of danger by mistaking the walking path and meeting with obstacle against walking direction. Here, system conduct warning by detecting the tactile paving and obstacles on it. Thus, potential accidents involving visually handicapped people can be prevented. The system guides the user by interpreting the information obtained from the automatic detection of the tactile paving. In this paper, the automatic tactile paving is mainly discussed, by processing images from on-user camera which exists in the main system. We propose a new HSV conversion-based image processing approach to detect tactile paving. Ultimately, the results of the experiments confirm the achievement of high tactile paving detection rates.
