Method, device and system for detecting ship water gauge line

The invention discloses a method for detecting a ship water gauge line. The method comprises the steps: acquiring an original image containing ship water gauge mark information through a mobile terminal; respectively inputting the original image into a horizontal line identification model and a water gauge mark identification model which are constructed in advance based on a depth separable convolution module to obtain a first image marked with a ship body water body boundary line and a second image marked with water gauge characters and contents thereof; and detecting the actual height of theship waterline according to the information marked in the first image and the second image. According to the invention, a lightweight deep learning network is used, and the detection precision and the detection speed are ensured at the same time, so that the collected image is processed at the mobile terminal. 本发明公开了一种用于检测船舶水尺线的方法，包括：通过移动终端获取含有船舶水尺标记信息的原始图像；将原始图像分别输入至预先基于深度可分离卷积模块构建而成的水平线识别模型和水尺标记识别模型中，得到标记有船体水体交界线的第一图像和
