Problems solved by technology
[0005] In order to solve the current correlation method between the navigation plan and the radar track, the similarity between the navigation plan and the radar track is constructed based on the information of the isolated point, which cannot reflect the overall matching of the navigation plan and the radar track. , for the poor adaptability of the ship's actual navigation route and the planned route, the outlier point of the radar track, and the delay of the navigation time, etc., it is necessary to provide a segment matching based navigation plan and radar track Association method and system

Embodiment Construction
[0031] like figure 1 As shown, the embodiment of the present invention provides a method for associating a flight plan and radar track based on segment matching, which includes the following steps:
[0032] S1. Read the flight plan: read at least one of the flight plans to be associated, and initialize the set of matching points, the set of matching points ratio, the set of spatial similarity and the set of temporal similarity between the sailing plan and the radar track.
[0033] S2. Determine whether there is a radar track that has not been calculated. If yes, execute step S3; otherwise, execute step S7.
[0034] S3. Read radar track: read one of the uncalculated radar tracks.
[0035] S4. Preliminary correlation judgment: Take the latest track point of the radar track that has not been calculated and project it to the navigation plan, comprehensively consider the historical correlation results of the navigation plan, the position of the projection point and the projection ...

The invention provides a sailing plan and radar track correlating method and system based on sectional matching. The method comprises the steps that a radar sailing track latest moment sailing track point status and sailing plan history correlating result is utilized for initial correlation judgment, a sailing plan and radar sailing track matching point set is constructed through time compensation and interval sampling, sailing track sections are constructed in the matching point set to carry out sectional matching, the number of points achieving successful matching and the proportion of the points in the point set are calculated, the space similarity and the time similarity are calculated, and finally a correlating result is obtained through comprehensive correlation judgment. According to the sailing plan and radar track correlating method and system, the sectional matching method is adopted in the sailing plan and radar track correlating calculation, the overall similarity of the sailing track is reflected by means of matching of the multiple sailing track sections, and influences of outliers and yawing on the correlation result are effectively reduced; in the correlation decision phase, comprehensive correlation judgment is carried out on the matching point number proportion, the space similarity, the matching point number and the time similarity, and the accuracy of the correlation result is improved.
Description
technical field [0001] The invention relates to a method for processing planning information data, in particular to a method and system for associating a navigation plan with a radar track based on segment matching. Background technique [0002] The voyage plan refers to the specific measures and countermeasures related to the voyage safety guarantee during the voyage that the ship draws up after accepting the voyage order. The voyage plan includes the entire process from berth to berth, the estimated total time of voyage, the estimated meteorological conditions and sea conditions on the route, the latitude and longitude of each turning point, the voyage of each section of the route and the estimated time of arrival at each turning point, and the navigation method of complex voyages As well as means of avoiding dangerous objects near the route, precautions in special navigation areas, etc. [0003] The purpose of the water traffic control system is to make the ships on the ...
