Abstract
The invention discloses a method for realizing the tracking of vessels in an anchoring/disanchoring state in a vessel traffic navigation system. When targets are anchored/disanchored, the method comprises the following implementation steps of: storing anchoring region positions of different information sources in configuration files in a certain format; constructing a point trace clutter map for anchoring regions, and generating three tracks, namely a reliable track, a fixed track and a temporary track; for anchoring targets, carrying out tracking treatment by using point traces remaining after finishing correlating the fixed track in the anchoring regions so as to eliminate the influence on the anchoring targets caused by fixed targets as much as possible; and for disanchoring targets, carrying out tracking treatment by using point traces remaining after finishing correlating the reliable track and the temporary track in the anchoring regions so as to eliminate the influence on the anchoring targets caused by the fixed targets and normal traveling targets as much as possible. The method has the advantages that the probability of correlation error caused when the targets are anchored/disanchored can be reduced, and the possibility of tracking failure during anchoring and disanchoring is reduced.
Description
One technical field
The present invention relates in a kind of vessel traffic navigational system the ship tracking implementation method under the state that casts anchor, weighs anchor; Belong to the radar target process field; Refer in particular to be used for that target in the vessel traffic navigational system (Vessel Traffic System, be called for short VTS) is passed through bridge and the state that casts anchor, weighs anchor under tracking technique.
Two background technologies
In VTS, when target cast anchor, when weighing anchor, all possibly there are a large amount of static targets in the periphery of target, owing to cover and hypotelorism, the situation that Targets Dots is lost can occur, and can cause the failure of target following like this.At this moment, target is in the process of casting anchor, weighing anchor, and the detection probability of target can reduce, and radar need continue it is followed the tracks of in this process.Whole consider from monitoring like this, be necessary to target cast anchor, the process of weighing anchor carries out special processing, guarantees the continuity and the accuracy of following the tracks of.
In the radar surveillance zone; The situation on river surface or sea is often very complicated; Navigator is arranged and do not have navigator ship, AIS (Automatic Identification System is arranged; Ship automatic identification system) equipment and do not have the ship of AIS equipment, large, medium and small target to exist simultaneously, and target is often than comparatively dense.These adverse factors have brought very large difficulty all for the tracking of casting anchor, weigh anchor of target.If cast anchor, the failure of weighing anchor, can cause track rejection or target following mistake, might bring major accident, as the collision etc.
Therefore, the accurate tracking of target all has crucial meaning for overall navigation, management, and this case promptly is based on such consideration and produces.
Three summary of the invention
Technical matters to be solved by this invention; Be to defective and deficiency in the aforementioned background art; Target Tracking Realization method under special circumstances is provided in a kind of vessel traffic navigational system, and it can reduce the possibility of associated errors, reduces the possibility of following the tracks of failure.
The present invention is for solving above technical matters, and the technical scheme that is adopted is:
The target Tracking Realization method under the state of casting anchor, weigh anchor comprises the steps: in a kind of vessel traffic navigational system
Target is cast anchor, is weighed anchor:
(1) with the anchor zone position of different aforementioned sources with certain format in configuration file;
(2) the anchor area is made up some mark clutter map, generate three kinds of targetpaths, reliable flight path, fixedly flight path, temporarily flight path;
(3) target to casting anchor, utilize anchor district internal fixation track association to accomplish after remaining some mark, the processing of following the tracks of;
(4) target to weighing anchor, remaining some mark after utilizing anchor district internal fixation flight path and reliably track association being accomplished, the processing of following the tracks of.
The present invention combines the technology of tectonic setting hum pattern and associated match; Wherein, The tectonic setting hum pattern is to utilize the position distribution of certain hour scope internal object relevant with target speed; Thereby extract the residing environmental information of target, this category information has regular hour and spatial stability; Utilize the associated match technology, can improve target and the related correctness of some mark.After adopting such scheme, system will have that real-time is good, the accuracy rate of target following and the high characteristics of stability.
Four description of drawings
Fig. 1 is the invention thought synoptic diagram that the present invention is cast anchor, weighed anchor and follows the tracks of;
Fig. 2 is the process flow diagram that the present invention is cast anchor, weighed anchor and follows the tracks of.
Five embodiments
As shown in Figure 1; It is the invention thought synoptic diagram of the implementation method that target is cast anchor, weighed anchor in a kind of vessel traffic navigational system of the present invention; It is that technology with tectonic setting hum pattern and associated match combines; And the target that is applied in the vessel traffic navigational system casts anchor, weighs anchor, practical implementation step such as following, and can cooperate shown in Figure 2:
(1) with the anchor zone position of different aforementioned sources with certain format in configuration file; The anchor zone position is identified by a series of effective line segment on the orientation, and the terminal point of line segment and starting point are represented the distance of anchor district on this orientation respectively.
(2) the anchor area is made up some mark clutter map, generate three kinds of targetpaths, reliable flight path, fixedly flight path, temporarily flight path; In the radar power range, divide the grid on the geographic significance with certain size; Utilize multiply periodic data, the track initiation technology of using in the distributed area of combining target movement velocity and the ordinary radar data processing is set up the targetpath of some mark clutter map and three kinds of different conditions.
(3) target to casting anchor, utilize anchor district internal fixation track association to accomplish after remaining some mark, the processing of following the tracks of; Remaining some mark after utilizing anchor district internal fixation track association to accomplish, the processing of following the tracks of can be eliminated the influence of fixed target to the target of casting anchor as much as possible
(4) target to weighing anchor, remaining some mark after utilizing anchor district internal fixation flight path and reliably track association being accomplished, the processing of following the tracks of.Remaining some mark after utilizing anchor district internal fixation flight path and reliable track association to accomplish, the processing of following the tracks of can be eliminated the influence to the target of casting anchor of fixed target and cruising target as much as possible
Above embodiment is merely explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of on the technical scheme basis, being done all falls within the protection domain of the present invention.
