Abstract

In this study, we developed a lane detection and motion-blur compensation system for tunnel inspection. It was undertaken considering the need for a highly safe and inexpensive inspection method for highway structures to replace the conventional visual and hummer sounding inspection. To further improve the positional accuracy of deterioration detection, we 1) proposed an accurate and convenient printing method that is based on silkscreen printing using retroreflective paint and 2) developed a method for creating barcode markers that can be printed on the surface of concrete.
