Automating inspection of critical infrastructure such as sewer systems will help utilities
optimize maintenance and replacement schedules. The current inspection process consists …

The maintenance and inspection of sewer pipes are essential to urban infrastructure but
remain predominantly manual, resource-intensive, and prone to human error …

The increasing aging of underground pipe networks and the lack of effective inspection
technologies present considerable challenges for whole life-cycle management of these …

A novel inline inspection (ILI) approach using depth cameras array (DCA) is introduced to
create high-fidelity, dense 3D pipeline models. A new camera calibration method is …

The development of a virtual scenario is desirable in many hostile environments such as in
mining or sewer pipelines to inspect its current condition and to identify possible failures …

This paper presents a new algorithm for automated crack detection in sewer inspection
closed-circuit television (CCTV) images. Cracks often have a long and thin rectangular …

This paper discusses the development of a general framework and software system to
support automated analysis of sewer inspection closed-circuit television (CCTV) videos. The …

Efficiently reconstructing dense, complete, and accurate 3D models of long and complex
pipelines remains a challenging task. The complex pipelines often contain geometrically …

There are many kinds of defects in pipes, which are difficult to detect with a low degree of
automation. In this work, a novel omnidirectional vision inspection system for detection of the …

The task of detecting and classifying damages in sewer pipes offers an important application
area for computer vision algorithms. This paper describes a system, which is capable of …
