A spiral avoidance display method and system for a target sign

By using a spiral avoidance display method for target signs, the number of trajectory targets is dynamically determined, a processing area is formed, and sign avoidance calculations are performed. This solves the problem of information judgment difficulties caused by overlapping trajectory target signs, and improves rendering efficiency and display effect.

AI Technical Summary

Technical Problem

When displaying a large number of trajectory targets, the severe overlap of trajectory target signs makes it difficult for operators to quickly judge information changes, resulting in incorrect information display and difficulty in obtaining information in real time.

Method used

The spiral avoidance display method for target signs is adopted. By dynamically judging the number of trajectory targets, selecting the number of trajectory targets to be stored, forming a processing area, and performing sign avoidance calculation, including center of gravity calculation and spiral search, adjusting calculation parameters to eliminate obstruction, and rearranging signs.

Benefits of technology

It effectively reduces the number of iterations in calculating trajectory target signs, improves rendering efficiency, eliminates occlusion, and achieves more effective sign display.

Abstract

The present application belongs to the technical field of graphic processing display, and provides a spiral avoidance display method and device for target labels, which comprises the following steps: dynamically judging the number of trajectory targets, selecting a set to store the selected number of trajectory targets, and judging whether there is a selected trajectory target in the selected set; when it is judged that there is a selected trajectory target in the selected set and the number is one, taking the selected trajectory target as the center to form a to-be-processed area, performing label spiral avoidance calculation on all trajectory targets in the formed to-be-processed area, and further obtaining a label avoidance result; when it is judged that there is no selected trajectory target in the selected set or there is more than one selected trajectory target, forming an external rectangle, performing external rectangle grid division, and then rearranging and placing labels of all trajectory targets to obtain a label avoidance result, which is displayed on a map on a screen. The present application effectively reduces the iteration number of trajectory target label calculation and improves the rendering efficiency of trajectory target labels.
