Ship safety forewarning method based on classification detection of collision

Abstract

The present invention discloses a ship safety forewarning method based on a classification detection of collision. The ship safety forewarning method provided by the invention comprises the following steps: (a) acquiring state information of a ship on the basis of an established three-dimensional virtual scene of a ship navigation channel; (b) classifying the collision types according to the driving direction angle with respect to the ship in the three-dimensional virtual scene; (c) calculating the minimum safe distance among ships through different determination methods of collision types; and (d) performing collision determination and emitting safety warning to the ships in a dangerous situation. The ship safety forewarning method based on classification detection of collision provided by the invention is capable of visually and accurately determining the ships in a potential collision danger in the navigation channel three-dimensional virtual scene in advance, and has the advantages of good accuracy, low operation cost, low interference rate and good application prospects.

Description

technical field [0001] The invention relates to a safety early warning method based on collision classification detection and belongs to the technical field of computer graphics. Background technique [0002] Inland waterway shipping is an important basic and service industry of the national economy and an important part of the comprehensive transportation system. While the country's economic growth has driven the rapid development of the shipping industry in recent years, the situation of water traffic safety has become more severe. With the development of maritime informatization, the focus of supervision has changed from post-emergency to pre-warning. As the key technology of intelligent ships, the ship's intelligent anti-collision warning technology has attracted increasing attention because it can greatly reduce maritime traffic accidents and improve navigation safety. [0003] At present, ship collision detection often uses distance, time or other related indicators ...

AI Technical Summary

Problems solved by technology

The safe distance algorithm, safe angle algorithm and safe area algorithm can only address the problem of straight line collision; data mining methods need to establish a knowledge base; although the collision time algorithm can solve the collision problem in all directions, the algorithm is complex and the calculation cost is high, so it is not easy to implement
