In response to the low efficiency and high cost of manual inspection for the risk of embankment piping

as well as the lack of flexibility and efficiency in geophysical methods

this article proposes the adoptionof drone technology to detect and locate the risk of embankment piping during the flood season. The article explores the image processing technology

coordinate transformation

and piping point positioning technology of drone inspection in the detection of piping hazards. Through engineering application cases

it details the application ofdrone inspection in the detection and positioning of piping hazards in embankments. The results show that by carrying an infrared camera

drones can detect and accurately locate the risk of embankment piping around the clock. Through infrared images

missed points in manual inspections can be detected

which has significant advantages compared to other methods. The drone inspection can preliminarily achieves rapid identification and location of embankment piping in flood season

moves forward the critical point of embankment safety defense

and ensures embankment safety.
