Ship early warning method

Abstract

The invention relates to a ship early warning method. The method comprises the steps that a ship peripheral object detection alarm system is provided, the alarm system comprises a camera component, a sensor component, image preprocessing equipment, object identification equipment, object feature extraction equipment, object template storage equipment and processing equipment, the camera component, the image preprocessing equipment, the object identification equipment and the object feature extraction equipment are connected in sequence to obtain features of ship peripheral objects, the processing equipment is respectively connected with the object feature extraction equipment and the object template storage equipment to identify types of the objects, and the processing equipment achieves object detection alarms based on object distances respectively detected by the object feature extraction equipment and the sensor component. Through the method, a ship can detect the existence of the peripheral objects of a ship body conveniently in time, the types of the objects can be further identified, and meanwhile corresponding alarm information can be provided according to the relative position condition of the targets and the ship body.

Description

Technical field [0001] The invention relates to the field of ship early warning, in particular to a ship early warning method. Background technique [0002] With the development of the world economy and the continuous growth of import and export trade, maritime traffic has become increasingly busy, and the number of large-scale and modern ships has continued to increase. This has made the originally insufficient waterways, ports and coastal waters become more crowded and traffic accidents continue. At the same time, the increase in marine garbage and the frequent collisions between some near-ship targets and the hull have also brought safety hazards to the normal operation of ships. When the ship's hull is damaged due to collisions with other ships or near-ship targets, it will not only bring significant economic losses to the ship’s operator, but also a major collision accident will cause personal injury to the people on board, if it is a large oil tanker , It may even cause th...

Problems solved by technology

[0004] However, there are some disadvantages in the existing target detection and alarm system near the ship: (1) it can only detect the target near the ship, but cannot identify the target, which is inconvenient for the crew on board to formulate a driving strategy; (2) the degree of electronic Low, it is impossible to dynamically display the shape of multiple near-ship targets and the relative distance to the hull in real time; (3) Due to the complexity of the sea environment, the alarm system of the prior art has the possibility of false alarm
