Method and device for improving water gauge water level detection accuracy and storage medium

The invention discloses a method and equipment for improving water gauge water level detection accuracy and a storage medium. The method comprises the following steps: acquiring a water gauge picture, an improved YOLOv4 model and an improved Deeplabv3 + model; the water gauge picture is processed based on the trained improved YOLOv4 model to obtain prediction information of the water gauge picture, the prediction information comprises labels, confidence and position information of a prediction frame, and the position information comprises center coordinates of the prediction frame and the width and height of the prediction frame; cutting the water gauge picture based on a preset singular value decomposition algorithm and the prediction information to obtain a preprocessed picture; segmenting the preprocessed picture based on a trained improved DeepLabv3 + model to obtain a segmented picture and an edge line, the segmented picture being a picture including a projection point of a boundary line of a water gauge
