The main goal of this study is to propose a suitable method in order to reduce the detection cost of orbital defects, improve the efficiency of defect detection, and effectively achieve rail health assessment by combining UAV image acquisition and digital image processing technologies. The characteristics of the images collected by the UAV using the proposed appropriate method to deal with the defects, which Hough transform and horizontal projection method are used to extract the rail area. In the process of image enhancement for rail images, an improved local normalized image enhancement method is proposed, and a defect segmentation method based on maximum entropy threshold value is used for defect segmentation. According to the calculation and extraction of defect characteristics, a classification model is proposed based on the deep forest method to classify the two types of defects, namely spalling and crack. The results show that the proposed method can accurately and effectively classify the rail surface defects in a small sample and has a certain practical reference value.
