“…Because buried concrete pipes are patterned and poorly lit, robust feature extraction is an essential step and appears throughout the pipe inspection literature. Methods include edge detection [25] [22] or the Hough transform [22] for edge/line detection, image segmentation [26] and background subtraction [18] for foreground object extraction, methods of image registration [18] and optical flow [24] for the tracking and association of objects in successive video frames, particularly relevant in CCTV imaging. More advanced methods include texture-based methods, including co-occurrence [21] and histograms of oriented gradients [23], and multi-resolution or wavelet-based approaches [29] [17].…”

“…Nevertheless, the limitations of the preceding paragraph notwithstanding, neural approaches have seen rather significant application in buried pipe inspection. In most cases, the neural network is preceded by computer vision approaches for feature extraction, followed by neural learning [29] [27] [20] [21] or neuro-fuzzy approaches [26] [88].…”

This review paper presents the current state of practice of assessing the visual condition of vertical and horizontal civil infrastructure; in particular of reinforced concrete bridges, precast concrete tunnels, underground concrete pipes, and asphalt pavements. Since the rate of creation and deployment of computer vision methods for civil engineering applications has been exponentially increasing, the main part of the paper presents a comprehensive synthesis of the state of the art in computer vision based defect detection and condition assessment related to concrete and asphalt civil infrastructure. Finally, the current achievements and limitations of existing methods as well as open research challenges are outlined to assist both the civil engineering and the computer science research community in setting an agenda for future research. Keywords:Computer Vision, Infrastructure, Condition assessment, Defect detection, Infrastructure monitoring Research Highlights: Visual inspection of civil infrastructure is essential for condition assessment.  We focus on concrete bridges, tunnels, underground pipes, and asphalt pavements.  Accordingly, we review the latest computer vision based defect detection methods.  Using computer vision most relevant types of defects can be automatically detected.  Automatic defect properties retrieval and assessment has not been achieved yet . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 ...

“…The neural network analysis technique was found helpful in identifying four categories of sewer defects: cracks, joint displacements, reduction of cross-sectional area. [6] Developed an automated sewer inspection data interpretation system. The other approach is to predict a sewer's existing condition prior to its detailed inspection for selective, cost effective sewer inspection.…”

Sewer overflows may cause communities to be vulnerable to various health problems and other monetary losses. This puts a lot of burden on responsible to minimize end user complaints. Therefore, crack prediction would be helpful to facilitate decision makers to control sewer overflow problems and prioritize inspection and rehabilitation needs .The accurate prediction of current underground sewer pipe cracks must be done before any pipe crashing with enough period of time to enable rehabilitation and replacement intervals, appropriate remedial methods and preventing sewer pipes crashing. Unfortunately, traditional technologies and models approaches have been limited to predict the development of sewer pipe cracks. In this paper, we address the problem of crack prediction of such cracks. This paper provides a proposed model which predict crack and cracks developments in any period of time that may occur in weak areas of a network of pipes.. We evaluate our results by comparing them with those obtained by many other models. The accuracy percentage of this model exceeds 90% and outperforms other approaches.

“…Over the past two decades, soft computing techniques have been developed to assess the condition of civil infrastructure. Some of these techniques include artificial neural networks (Sinha 2004Kuzniar et al 2006, Bayesian network (Naidu et al 2006), neuro-fuzzy approach (Chae and Abraham 2001), fuzzy synthetic evaluation , and fuzzy rule-based modelling (Najjaran et al 2006). However, these techniques do not rationally account for confirmatory and/or contradictory information.…”

Pipe deterioration is a physical manifestation of the aging process in which many factors can contribute to structural failure. Various technologies/ techniques have been developed during the last few years to inspect/monitor piping systems, but how to intelligently interpret the collected data remains a challenge.In this paper, a new approach based on hierarchical evidential reasoning (HER) is proposed.This approach uses Dempster-Shafer (D-S) theory to make inferences for condition assessment of buried pipes. A hierarchical evidential reasoning model can help combine different distress indicators (bodies of evidence) at different hierarchical levels using D-S rule of combination.The proposed hierarchical evidential reasoning method is demonstrated with an example of condition assessment for a large ...
