Buoy identifying and tracking method

Abstract

The invention relates to a buoy identifying and tracking method. The buoy identifying and tracking method comprises the following steps: 1) obtaining a location point and a variable radius of a buoy, wherein the location point is a geographical location of the buoy and the variable radius is a predicated trace window radius used for tracking; 2) initializing the obtained buoy to obtain an initial buoy, and adding the initial buoy into an initial buoy list; 3) dividing a radar image into a plurality of sector shapes, randomly selecting one sector-shaped section for initial buoy identification in the sector-shaped section, so that the buoy, which is subjected to the initial buoy identification, of the sector-shaped section becomes an identified buoy; tracking the identified buoy in the sector-shaped section; and after the buoy of the sector-shaped section is identified and tracked, identifying and tracking a buoy in the next adjacent sector-shaped area until buoys in the entire radar image are identified and tracked. The buoy identifying and tracking method can be widely used for the field of identification and tracking of radar track targets.

Description

technical field [0001] The invention relates to a target identification and tracking method, in particular to a buoy identification and tracking method. Background technique [0002] The current radar target recognition technology usually does not consider special treatment for buoys, but uses the same process to identify buoys and ship targets. Because there is no special identification for the buoy, but the buoy is identified as the track target of the stationary ship, so the buoy (the characteristic of the buoy's own motion state is that the motion of the buoy is always within a certain range, and the direction of motion is not fixed) is used as a ship. The target is processed, and the track target of the real ship will be affected by the buoy, thus affecting the correctness and accuracy of track tracking. [0003] The existing buoy recognition technology usually adopts the method of manually recording the range of buoys, and the buoys are initialized only by manually en...

[0003] The existing buoy recognition technology usually adopts the method of manually recording the range of buoys, and the buoys are initialized only by manually entering the buoy positions by the user. Due to the large number of buoys in the monitoring area, the workload of the user increases, and there are incorrect inputs that cause tracking errors. correct phenomenon
