Abstract:Based on U-net, a new method of automatic segmentation water level line is proposed and validated through a variety of scenarios. Firstly, the water and background in the original image are marked and grayscale. Then, the processed image and the original image are used to make the data set. The data set is used as the input to segment the image. Finally, all the segmented images are extracted to obtain the water level line. As the experimental results show that the automatic segmentation of U-net can accurately mark the water level and solve the influence of image background in the process of water level measurement. The recognition rate of U-net water level automatic segmentation method is above 96%, and the segmentation effect is better than other segmentation methods.
