Detect and identify earth rock embankment leakage based on UAV visible and infrared images

Automatic Identification of Earth Rock Embankment Piping Hazards in Small and Medium Rivers Based on UAV Thermal Infrared and Visible Images

“…The complex background of these objects may hinder the identification of piping hazards [27]. The sole use of visible or thermal infrared images is constrained by the former's unavailability during night-time and, with the latter, feature types cannot be differentiated [6,24,25]. Therefore, our study primarily relied on thermal infrared images with the supplementary use of visible images.…”

“…The algorithm uses the image data collected by the UAV to investigate and determine the piping hazard situation. At present, the intelligent methods of identifying piping can be roughly divided into two types [6,24]: image identification technology based on machine learning, in which a piping identification model is constructed for danger discrimination through a large number of training and labeled samples, and image segmentation methods based on thermal imaging principles and the maximum interclass variance method. The application of the first type of method is limited by the lack of both the in-depth mining of the characteristics of piping mechanisms and a massive real sample library; the second type of method is restricted by the identification algorithm being unable to overcome the interference caused by various weather conditions and the complex ground object background during the identification of piping [25,26].…”

Deformation and Stability Analysis of a Core Rockfill Dam with Leakage

“…When the reservoir water level rises or falls suddenly, the seepage eld in the dam changes greatly in a short time, a ecting the stability of the dam, especially for the upstream slope of the dam. For this reason, researchers and technicians have done a lot of work on the aspects of anti-seepage technology, dam safety monitoring methods, and Earth rock dam disease mechanism to solve the problem of dam leakage [8][9][10][11]. However, due to the limitation of the technical level during the construction period or the comprehensive impact of the later transportation and maintenance, there are still hidden dangers in the seepage stability of a large number of reservoir dams.…”
