As part of steep slope maintenance plan along the roadcuts in mountainous regions in KOREA, we have developed a vehicle-mounted joint survey system utilizing digital imaging technique. This system is comprised of three parts;
part for acquisition of still images and video,
part for image analysis, and
part for remote wireless transmission.
The goal of the system is first to detect precursory signatures of slope failure, and second to provide fast countermeasures against such slopes. In order to accomplish the goal, the system was configured to allow visual observation and judgment for rock slope, measurement of digital imagery sets for rock joint geometry, and remote wireless transmission of various slope datum including high resolution still images, video images, and geometric characteristics of joints such as orientation, spacing, length. Compared with the traditional methods for slope maintenance, the system is far more effective since it allows rapid decision making during. In this paper, details of the system, verification, and the result of field application are described.
