AbstractThis paper describes the development of a software system to semi-automatically extract historical condition data information from archived sewer inspection CCTV files. The software represents and manages the sewer data in a centralized repository. Users can easily access inspection and condition data via a GIS interface. The software implements video processing algorithms to support semi-automatic evaluation of the CCTV recording by automatically detecting defect features and assisting the user to define scores and rating according to a pre-defined condition rating scheme. The software was successfully used to efficiently access, analyze, and evaluate sewer condition data from CCTV video files obtained from the City of Regina.
