In order to solve the problem of larger error caused by complex environmental interference and tunnel geometry shape in the tunnel leakage area detection, a leaky water area detection algorithm based on FCN and field cylinder projection algorithm was designed. The unmanned disease inspection vehicle was developed to realize the unmanned collection of tunnel disease data. The accuracy of the calculated disease area is improved by performing field-field conversion and cylindrical projection model optimization on the FCN-treated water leakage disease picture. The experimental results show that compared with the OSTU method, the watershed method and the adaptive threshold method, the algorithm reduces the false detection rate to 0.0189, which effectively improves the accuracy of tunnel leakage area detection.
