Ship navigation system and ship navigation method

Abstract

The present invention provides a ship navigation system and a ship navigation method. Laser signals are transmitted and received through a laser radar to form point cloud data, radar calibration is carried out through radar calibration equipment, conversion from a laser radar coordinate system to a ship coordinate system and fusion of point clouds at all positions are completed, and very high frequency antenna signals are received through an AIS receiver to form AIS data. The industrial personal computer equipment receives point cloud data from the radar calibration equipment and AIS data from the AIS receiver at the same time, the industrial personal computer equipment carries out collision risk calculation and carries out early warning on ship collision risks, the industrial personal computer equipment carries out point cloud target identification and point cloud data and AIS data matching, and ship driving is assisted through visualization processing. According to the invention, the collision risk is calculated in real time, the navigation safety is ensured, the point cloud information is identified and overlapped with the AIS information for imaging, the inland ship driving is assisted, and the navigation safety is improved.

Description

technical field [0001] The invention relates to a ship navigation system and a ship navigation method. Background technique [0002] Inland waterway freight transport plays an increasingly significant role in the rapid development of urban economy. However, the risk of ship collision occurs from time to time, and human factors are an important cause of the risk. The development and application of ship automation technology should not be to eliminate human control, but to use technology to make up for the lack of human operation and minimize human errors. [0003] Among the current intelligent technologies that can be applied to ship navigation, lidar can accurately detect the distance and azimuth information of target obstacles in a short range, and has a good ability to resist rain and fog interference, which can effectively solve the problem of ships in complex waters and narrow waterways. The problem of short-range target detection in navigation, but the single percepti...

Problems solved by technology

[0003] Among the intelligent technologies that can be applied to ship navigation at present, lidar can accurately detect the distance and orientation information of target obstacles in the short range, and has a good ability to resist rain and fog interference, which can effectively solve the problem of ships in complex waters and narrow waterways. The short-distance target detection problem of navigation, but the single perception performance of lidar cannot provide reliable decision-making basis for the driver; electronic chart equipment is widely used in ship navigation, which effectively improves the safety rate of ship navigation, but the electronic chart The device displays the dynamic information of the ship is relatively vague, and the display effect is two-dimensional, which cannot give the operator an intuitive perspective
