Detection system and detection method

Abstract

To detect deformations in railway track rails with high precision. [Solution] The detection system 1 is mounted on a railway vehicle that runs on a pair of rails R and includes an imaging unit 21 that outputs an image 50 of the pair of rails R, a first detection unit 42 that inputs the image 50 to a first trained model to detect the pair of rails R, a generation unit 43 that generates preprocessed images 56 and 57 of the detection target portions A1 and A2 of the pair of rails R from the image 50 based on the detection result of the first detection unit 42, and a second detection unit 44 that inputs the preprocessed images 56 and 57 to a second trained model to detect deformations D1 and D2 in the detection target portions A1 and A2.
