Abstract

It is said that the number of visually impaired persons becomes about 310,000 in Japan, and the number of visually impaired persons is increasing every year now. Tactile paving surfaces, therefore, take a very important role. A lot of tactile paving surfaces for inappropriate, however, exist. This paper is intended to detect deficient tactile paving surfaces. At first, tactile paving surfaces regions are extracted by color thresholding. Then, deficient tactile paving surfaces are judged by the outline tracing and the position estimation of the tactile paving surfaces.
