Paper Abstract

We have developed the 'position measurement method' to determine the GPR's position on the road by accurately measuring the distance and direction in which it has moved, as well as '3D visualization software' to compile data of cross sections and reconstruct three-dimensional structure of buried objects. With the 'position measurement method' we have developed, survey data can be obtained by operating the GPR in arbitrary directions, while maintaining a survey speed corresponding to normal walking speed. And '3D visualization software,' developed for Windows PC, has main features as follows: (1) Survey data obtained by both arbitrary and parallel line operations can be visualized three- dimensionally; (2) High speed migration processing to improve the horizontal resolution; (3) 2D placement of objects buried at various depths can be easily detected; (4) 3D structure of the buried objects can be easily extracted.
