In this study, it was evaluated the detection results of ground penetration radar (GPR) by using pixel difference. Experimental tank was made for this purpose. Concrete hume pipe and PE pipe were buried in the tank. The pavement finish of the surface was classified 4th cases. In the case of non-reinforcement concrete pavement, the buried pipe detection was easy than other pavement cases. And it was easy to detect the buried pipe by the difference of the color pixels rather than the black and white pixels.
