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.
