Abstract
A system includes a visual inspection system and an image analysis system. The visual inspection system includes an inspection camera that captures images from within an interior of at least one of a utility line and a tunnel for installing a utility line, and a first communication interface that communicates image data corresponding to the images. The image analysis system includes a second communication interface that receives the image data from the visual inspection system, a model adaptation module that modifies a classifier model based on at least one of feedback data and training data, and a classifier module that implements the classifier model to identify a plurality of features in the image data corresponding to defects and that modifies the image data according to the identified plurality of features. The defects include at least one of a cross-bore, a lateral pipe, and an imperfection.
