Underwater target motion dynamic visualization method and device

Abstract

The invention provides an underwater target motion dynamic visualization method and device, and solves the technical problem of lack of reliable means for analysis and rule mining of target dynamic characteristics in the prior art. The method comprises the following steps: setting a reference object sequence on a navigation track formed by a moving target, and forming a morphological attribute of a reference object according to time sequence dynamic data along with the navigation track; through a graph mapping method, plotting moving target determined type dynamic data on a track curve, rapidly finding out a change rule of a dynamic data value, and providing a means and a basis for motion feature extraction and motion process analysis. The change state of the motion description type is fully displayed and determined, the change rule of various dynamic data values in the whole motion process of the target is displayed, dynamic process change points can be quickly captured through visual determination, and a technical means is provided for motion feature extraction and analysis of the motion target.

Description

technical field [0001] The invention relates to the technical field of data visualization, in particular to a dynamic visualization method and device for an underwater target. Background technique [0002] In the prior art, the track of the moving target is displayed in the form of a continuously changing curve in the ocean space digital sand table, but for the moving state of the moving target, at present, only one or some types of current can be displayed beside the moving target according to the orientation of the camera. The real-time quantitative value of the motion state cannot effectively display the continuous dynamic changes of the moving target, and lacks the visualization means to form the continuous change law. Part of the active or passive movement characteristics of moving targets cannot be expressed through the graphical display process, and the analysis and mining of dynamic changes such as speed, probability distribution of detection, or coverage of detectio...
