Ship and water floating object track tracking system

Abstract

The invention provides a ship trajectory tracking system based on a video target detection technology, which is used for tracking ship trajectories of all ships in a target navigation channel, and ischaracterized by comprising a plurality of video acquisition devices and a trajectory tracking device; the video acquisition device includes a video acquisition unit and an acquisition-side communication unit. The trajectory tracking device includes a trajectory temporary storage unit, a target recognition unit, a trajectory analysis unit, and an output unit. The trajectory analysis unit includes:a predicted value acquisition unit for acquiring a predicted coordinate value of a target ship; a threshold association establishment unit used for establishing threshold association according to thepredicted coordinate values; a matching value judgment and acquisition unit used for acquiring a matching observation coordinate value according to threshold association; and a accurate value acquisition unit used for acquiring the current track of the target ship according to the matched observation coordinate values.

Description

technical field [0001] The invention relates to the fields of bridge safety and navigation information safety, in particular to a track tracking system for ships and floating objects on water. Background technique [0002] The ship collision accident has a great impact on the safe transportation of bridges and roads, people's life and property, and even the development of social economy. With the continuous economic growth and the increasing demand for transportation facilities, the number of bridges in my country is increasing. The construction of large bridges can relieve traffic pressure and promote land transportation. However, for water ships, bridges are artificial obstacles. When ships sail under the bridge, there is a danger of colliding with bridge piers or bridge span structures, which poses a threat to the safety of bridges and ships, and at the same time poses a threat to the safety of waterways and land traffic. normal functioning is also a threat.

AI Technical Summary

Problems solved by technology

The existing video monitoring methods for bridge collision avoidance do not pay much attention to the identification of the motion state of the ship target, and only use the target position as an assessment index of the collision risk, but do not include the motion state of the target into the risk assessment system from the perspective of track tracking, and there is no such thing as yet. Track tracking method to solve interference factors such as complex environment of waterway, visual occlusion, bridge vibration, etc.
