Abstract

A system for measuring freeboard height of a ship and a measuring method thereof are disclosed. The system for measuring that freeboard height of a ship comprises a steering gear, a lidar, a water level gauge and an MCU controller, wherein the steering gear is fixed on the bottom of a bridge; the lidar is fixed on the steering gear and rotates with the steering gear; the water level gauge is fixedon the shore and arranged below the water surface; and the MCU controller is used for controlling the steering gear to rotate and receiving the data measured by the lidar and the water level gauge, and transmitting the data to the remote server for processing and analysis. The system for measuring that freeboard height of a ship has the advantages that as the combined measuring method of the lidar and the water level gauge is comprehensively used, the water level can be monitored in real time, and the freeboard height of the ship can be accurately measured, and the overload problem of the ship can be monitored, and the environmental impact of the measuring method is small, and certain accuracy can be maintained at night and in various climates.

Description

technical field [0001] The invention relates to a measuring system, in particular to a ship freeboard height measuring system and a measuring method thereof. Background technique [0002] Most of the existing ship freeboard height measurements use image processing technology, use the camera to take pictures of the ship, and then transmit the captured photos to the server for image processing to obtain the freeboard height. There are two key defects in this technology. One is that the shooting of the camera is greatly affected by the environment, and it cannot provide photos that can be image processed in some environments. The other is that the data obtained after image processing may have large errors. , more precise data cannot be obtained. Contents of the invention [0003] The purpose of the present invention is to provide a ship freeboard height measurement system and its measurement method, which uses the combined measurement method of laser radar and water level ga...
