Multi-light-spot tracking device and method

Abstract

The invention provides a multi-light-spot tracking method. The multi-light-spot tracking method comprises the following steps: step 1: acquiring geographic position information corresponding to different moments of two or more than two target warships and converting the geographic position information into projection pixel point coordinate data corresponding to light spots on a drawing, wherein one projection pixel point coordinate data corresponds to geographic position information of one warship at the present moment; and step 2: projecting the light spots on the drawing according to the projection pixel point coordinate data corresponding to each light spot. According to the multi-light-spot tracking device and method provided by the invention, the geographic position information of the plurality of target warships is converted into the projection pixel point coordinate data corresponding to the light spots on the drawing through a data processing unit, so that a projection unit can realize a tracking aim of simultaneously tracing at least two target positions in a target position tracing process, and furthermore, the problem that a position indicating device in the prior art cannot simultaneously trace at least two dynamic target positions is solved.

Description

technical field [0001] The invention relates to the field of traffic mapping operations, in particular to a multi-spot tracking device and method. Background technique [0002] At present, when using traffic charts such as maps, nautical charts, and aerial charts, it is necessary to mark the coordinate data of the known location (such as: Cartesian coordinates X, Y of the target position or geographic coordinates longitude, latitude, etc.) on the paper map come out. According to the coordinate data of the above-mentioned known position, use the measuring tool to measure and calculate the target distance (the distance between the target rectangular coordinates in the X direction and the Y direction, or the distance between the longitude and latitude of the geographic coordinates), and mark it on the paper according to the target distance. target location. If the current measurement target is a moving target, the above work needs to be performed continuously. At present, th...

Problems solved by technology

This device brings convenience to the navigation plotting work, but the existing device can only indicate the position of one target. When multiple targets need to be tracked, different targets must be tracked by time-sharing switching. Therefore, it is only possible to switch to track one target at a time, so that when multiple targets are tracked during the tracking process, the problem of discontinuous tracking of the targets is caused, which further leads to low work efficiency when plotting and navigating the targets.
