To provide an abnormality detection system and an abnormality detection method for track material and wiring material capable of being introduced at relatively low cost and capable of handling a case when there are plurality of objects in an image and the objects have various shapes.SOLUTION: An abnormality detection system includes a camera 1 and an analyzer 2 for detecting an abnormality in an object by analyzing a moving image captured by the camera 1. An analyzer 2 includes: image reading means 3 for reading a moving image captured by the camera 1; conversion means 4 for converting the read moving image into a still image; area segmentation means 5 for segmenting the area including the object from the still image; object detection means 6 for detecting the object by a method using deep learning from the area image segmented by the segmentation means 5; and abnormal value detection means 7 for detecting an abnormal value by the method using the deep learning from the object detection image detected by the object detection means 6.SELECTED DRAWING: Figure 1
