Development of Image Processing Method for High Quality Pipeline Inspection

Sewer pipelines are buried underground and often forgotten until serious failure happens. Effective and reliable sewer system management is very important for the safe and clean environment. In order to maintain the intended capacity of pipes, effective maintenance based on accurate condition assessment is required. This research suggests a new method that uses digital still images to overcome the limitations of common CCTV pipeline inspection systems. As a result high quality images are obtained for accurate and effective condition assessment of pipelines.
