Problems solved by technology

1. When there are many ship signs gathered together, it is time-consuming and laborious to manually drag the signs one by one. In addition, with the navigation of the ship and the user's roaming operation on the electronic chart, the positions of the scattered ship signs will also change accordingly, which may If a new aggregation is generated, the user needs to repeat the process of dragging the signs one by one again, which is too cumbersome; 2. Manually dragging the signs, the position of the signs is often random, the arrangement is not neat, and it is neither beautiful

Embodiment 1

[0043] Such as figure 1 As shown, the key steps of the automatic arrangement method of the ship's electronic signage in the electronic chart of the present invention are as follows:

[0044] Prerequisite steps, non-essential technical features of the present invention:

[0045] The VTS platform display software receives the ship track message (including ship name, type, nationality, latitude and longitude position, direction, speed, etc.), where the latitude and longitude position of the ship is in degrees, for example, the position of the ship is 108 degrees 30 minutes east longitude. 108.5 degrees (positive value is east longitude, negative value is west longitude), 21 degrees 30 minutes north latitude is expressed as 21.5 degrees (positive value is north latitude, negative value is south latitude), the ship information structure is generated and stored in the memory in the list of information structures. The ship information structure also includes the corresponding elect...

Abstract

The present invention discloses a method for automatically sequencing electronic signs of ships in an electronic chart, and in particular a sign sequencing method for aligning the overlapped signs in a specific region based on a sequencing algorithm. According to the present invention, after overlapped informative signs of ships in an electronic chart, widths, heights and latitude information corresponding to the ships are analyzed; these overlapped signs are automatically spread and sequenced in a designated idle region in the electronic chart. This solves the problem that the signs are overlapped which causes interference to user's acquisition of valid information. The method according to the present invention, different from the convention method in which a mouse is used to drag one by one the signs overlapped, frame selects a large number of aggregated signs by using the mouse, and then spreads and sequence the signs in a designated position, thereby solving the problem of overlapped signs. Compared with manual spreading of the signs, the method according to the present invention can not only quickly solve the problem of a large number of overlapped signs , but also can make the sequenced signs more beautiful and ordered.

Description

technical field [0001] The invention relates to the technical field of electronic chart information processing, in particular to a method for automatically arranging ship information signs in electronic charts of a vessel traffic management system (hereinafter referred to as VTS). Background technique [0002] Vessel traffic management system refers to the management system used to ensure the safety and efficiency of sailing ships in a certain water area. Ships that actively report or are discovered by radar in the water area will be sent to the VTS station in the form of a message after fusion processing by the information center. The VTS station display software receives the ship track message (including ship name, type, nationality, longitude and latitude) After analyzing the longitude and latitude position of the ship's track, the corresponding longitude and latitude position on the electronic chart will draw the received ship's track in real time in the form of a label ...
