Problems solved by technology

However, when the targets are densely concentrated in a small area, the signs associated with the targets will cover each other, seriously affecting the reading of the signs, and the information display effect will drop sharply
[0003] At this time, system users often manually drag the signs to a recognizable position one by one; and every time the system is turned on, a new target appears or even the target moves, the process needs to be repeated, which is time-consuming and laborious , seriously reducing the user's work efficiency

Embodiment Construction

[0025] The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0026] The polygon signboard automatic arrangement method applied to the ship traffic management system of the present invention, such as figure 1 shown, including the following steps:

[0027] S1: Take out a newly added sign from the sign queue that needs to be added to the chart and add it to the chart. The shape of the newly added sign is quadrilateral or hexagonal;

[0028] S2: Judging whether the newly added sign overlaps with the existing sign in the chart: if not overlapping, proceed to step S5; if overlapping, establish an overlapping sign queue, and add each sign to the overlapping sign according to the overlapping area from large to small Queue, then take out the signboard at the head of the team, find out the placement position with the largest overlapping area with the newly added signboard in each placement position, and put the...

Abstract

The invention discloses a polygon-shaped sign plate automatic arrangement algorithm. According to the polygon-shaped sign plate automatic arrangement algorithm, based on the calculation and judgment of the location relations of newly-added sign plates and existing sign plates, the newly-added sign plates are automatically arranged around the existing sign plates, and therefore, the sign plates will not cover each other, and therefore, the problem of influence of sign plate overlapping on information display can be solved; sign plate location arrangement is carried out totally by means of a computer without any manual intervention required, and therefore, the required time and energy of a user can be decreased, and the efficiency of sign plate arrangement can be improved, and operation is convenient. The polygon-shaped sign plate automatic arrangement algorithm of the invention is a local algorithm and does not need to rely on global parameters of a system, such as screen resolution and map scale; and possible arrangement modes are saved through using a ''placement position" data structure, and therefore, the amount of computation can be reduced.

Description

technical field [0001] The invention relates to a method for automatically arranging polygonal signs applied to a ship traffic management system. Background technique [0002] In the vessel traffic management system, the target signage can prompt the key information of the target, such as the model, nationality, navigation information and other key information of the target, which is an indispensable element in the real-time information display. However, when the targets are densely concentrated in a small area, the signs associated with the targets will cover each other, seriously affecting the reading of the signs, and the information display effect will drop sharply. [0003] At this time, system users often manually drag the signs to a recognizable position one by one; and every time the system is turned on, a new target appears or even the target moves, the process needs to be repeated, which is time-consuming and laborious , seriously reducing the user's work efficien...
