The Design and Implementation of Military Plotting System Based on Speech Recognition Technology - Advances in Image and Graphics Technologies - page 266

Speech read module is based on the speech recognition software, from the voice
input equipment we can read the speech information of plotting personnel, then we
can convert the speech information to the command text; the plotting information
extraction module can draw the plotting information from the command text for the
implementation of plotting; the plotting function is used to realize plot, we can use
military geographic information system as platform, after plotting module obtains the
plotting information, we can find the corresponding military symbol code from the
data table, at last we realize the automatic plotting on electronic map using the mili-
tary symbol.

4 The Design of Speech Plotting Command

4.1 The Element of Plotting Command

In accordance with the requirements of military plotting, if you want to use the mili-
tary plotting, you need to determine the following elements: the color, size, location,
direction and note of military symbol [6]. As long as the elements are determined, you
can implement plotting.
The color of military symbol is determined by participating part sign, as the ma-
jority of military symbol denote our force are red, blue represents the enemy; we can
determine the size of military symbol according to unit level; positioning is deter-
mined by the current position coordinate.

4.2 The Design of Plotting Command

From the analysis of plotting command element, in order to realize plotting, the plot-
ting command should cover all the elements. According to the number of the position-
ing points, military symbol can be divided into punctate military symbol and linear
military symbol, punctate military symbol only need one location point, linear military
symbol needs two or more points, so we should design different plotting commands.

Fig. 2. The sketch map of different military symbols

According to the characteristic of punctate military symbol and linear military
symbol, we design the plotting command as follow.
