Track component detection method, terminal and storage medium

The invention provides a track component detection method and device, a terminal and a storage medium. The method comprises the following steps: acquiring a track image; inputting the track image into a track component detection model to obtain a component defect detection result of the track image and a track surface area, and obtaining a track surface detection result based on the track surface area; wherein the track component detection model comprises a feature extraction trunk, a component defect detection branch connected with the feature extraction trunk, and a track segmentation branch connected with the feature extraction trunk. A track component detection model used in the method comprises a feature extraction trunk, a component defect detection branch and a track segmentation branch, the feature extraction trunk only needs to perform feature extraction once, and the component defect detection branch and the track segmentation branch can perform component defect detection and track surface defect de
