Method and device for detecting target on subway track based on transfer learning

The invention provides a method and a device for detecting a target on a subway track based on transfer learning. The method comprises the following steps: acquiring long and short focus images to be detected from the subway track; based on a target detection model, performing target detection on the to-be-detected long-focus and short-focus image to obtain a target detection result; the target detection model is obtained by carrying out transfer learning on a basic target detection model based on sample image data under different illumination conditions; and displaying the target detection result. According to the method and the device provided by the invention, through the sample image data under different illumination conditions and the target detection model obtained by carrying out transfer learning on the basic target detection model, target detection is carried out on the obtained long-focus and short-focus images to be detected to obtain the target detection result, so that the accuracy and the compre
