Method and system for ship in bridge area to actively avoid collision based on laser three-dimensional imaging technique

Abstract

The invention discloses a method and a system for a ship in a bridge area to actively avoid collision based on a laser three-dimensional imaging technique. The method comprises the following steps of S1, enabling the actively avoid collision system to judge whether the ship enters a recognition area or not; S2, enabling a data collection module to collect data, so as to obtain collected data information; S3, enabling a data storage module to store waterway basic information and the collected data information; S4, enabling a data processing terminal to judge navigation opening and track according to the waterway basic information and the collected data information; S5, publishing decision information. The method has the advantages that the relative position between a bridge pier, a navigation beacon as well as surrounding ships and the ship in the inland river bridge area can be accurately judged; by utilizing the collected data information and the accurate bridge pier and navigation beacon position information in an electronic waterway map, the navigation state of the ship is predicted, so as to ensure the navigation safety of the ship in the inland river bridge area.

Description

technical field [0001] The invention relates to the technical field of active collision avoidance of ships in bridge areas. More specifically, it relates to a system and method for active collision avoidance of ships in bridge areas based on laser three-dimensional imaging technology. Background technique [0002] With the rapid development of my country's transportation industry, bridges, as the link of land transportation between the two sides of the river, are being built in more and more numbers and with higher density. For example, before the 1990s, there were only 7 bridges on the Yangtze River. By this century, there are more than 60 Yangtze River Bridges that have been built or are under construction from the Yibin section of the Yangtze River to the Yangtze Estuary. The completion and commissioning of these bridges, on the one hand, have provided great convenience for land transportation, facilitated people's lives and promoted regional economic development; on the...

Problems solved by technology

However, the GPS positioning module used in AIS has its own positioning error, and at the same time, the AIS signal is unstable and easy to lose

[0009] It can be seen that in order to realize the active navigation of ships in the inland bridge area, the existing navigation aids for inland river ships mainly have the following problems: 1), it is impossible to accurately judge the relative positions of piers, navigation marks, surrounding ships and the ship in the inland bridge area; 2), only Through the simple calculation of the nearest encounter distance and the arrival nearest encounter distance, there is no pre-judgment of the safety situation of the navigation for the movement trend of the ship; 3), there is no ship-borne equipment that can actively remind the driver of the avoidance method
