A New Method of Data Correlation Based on Point State Image Processing
Aiming at the problems of large calculation amount and obvious error association when traditional plot fusion methods are used for point data association processing in dense clutter environmentwe proposed a new data association method based on point state image processing.Firstlythe imagination of the point measuring was implemented according to sensor detection performance and the estimated target speed rangeand the image of point state was obtained.Secondlythe clutter points were eliminated by using image morphologic processing such as neighborhood connectivity discrimination and so on.Based on the time information included in the points corresponding to the pixel pointsthe classification of the points of different targets was realized by connected component labeling processing.Simulation result shows that the algorithm can avoid the combinatorial explosion in theoryreduce the amount of computationsolve the problem of error associationand improve the accuracy of the data association processing.
