Multi-Objective Information Processing And Research Of Plotting Method On Plotting Charts Units

Plotting charts units plays an important role in the maritime operations.In the complex maritime environment and the high demands of the maritime mission, the information processing of multi-source and multi-objective is particularly important.As current advanced technology of information processing, Information fusion can dealing efficiently with the multi-target information of charts plotting units and provide better protection for navigation mission.First,the article raised the relevant knowledge of multi-objective data pre-processing,illustrated the unification of time and space,and coordinate conversion of charts.Then,the article analyzed and discussed the data fusion structure and the formation of the target track and track association algorithm, gave a multi-objective algorithm model to seaworthy environment.Then researched multi-objective posture solution and multi-target elements of calculation,and dealt with multi-target ship's Preventing Collisions at Sea.To record more comprehensive state of the navigation environment,and provide more convenient,reference for the next phase of decision-making,we need plot other ship's course and the surrounding environmental elements of ships. Contrapose the existing single track plotting,this paper advanced an optimal path way to confirm the targets sequence,and a compensation plotting way to plot targets,which shortened the process of plotting time and enhance the multi-objective Plotting efficiency.On these bases,the paper made a structural design to switch multi-color pens and actualized multi-color plotting method which made the multi-target plotting on chart more intuitive.The last part of the article designed a man-machine interactive interface, finished data processing and showed an intuitive situation map on Linux operating system using the development tool Qt.
