Moving target aggregation method based on relative position

Abstract

The invention discloses a moving target aggregation method based on a relative position, and the method comprises the following steps: setting a distance threshold value and a range increment threshold value according to the motion features of moving targets; setting an aggregation target set, traversing and calculating the distances between all moving targets and the aggregation target, comparing the distances with a distance threshold, gradually expanding the set according to a comparison result, and simultaneously obtaining the farthest distance between the aggregation target and the moving targets contained in the aggregation target; based on the farthest distance and the range increment threshold value, obtaining a deviable area of each aggregation target, according to the relative position of the moving target in the aggregation target and the deviable area and the direction of the moving target, judging whether the moving target needs to be removed from the aggregation target, and enabling the removed moving target to participate in the calculation expansion of the set again. And dynamic aggregation is realized in the continuous movement process of the moving target.

Description

technical field [0001] The invention belongs to the field of real-time target monitoring and processing, and particularly relates to a relative position-based aggregation method suitable for moving targets such as aircraft and ships. Background technique [0002] With the continuous development of the global economy, the demand for aviation and navigation for cargo transportation, personnel flow and financial exchanges is increasing. According to the statistics of the International Air Transport Association (IATA), the daily average number of flights has exceeded 100,000. At the same time, with the frequent international battles and games, the unstable factors affecting the world security situation are increasing day by day, and the need for various application systems to control the global moving target situation is becoming more and more urgent. [0003] By introducing millions of moving targets into the system, when the two-dimensional map is large, the display effect wil...

Problems solved by technology

At present, the industry often adopts the method of dividing into meshes to aggregate and calculate the moving targets. Although these methods can solve the above problems, the original distribution and motion trend of the moving targets are lost after the aggregation calculation.
