军事标图系统中随机军标的生成与控制研究

采用扫描线填充算法,通过确定控制点进行曲线拟合,以及确定要绘制点图标的点坐标,构建随机军标的生成模型和控制模型.随机军标的结构控制包括围线与箭标两类,前者首先确定开曲线类军标给定的起始、终止两个控制点,然后确定军标的控制轴;后者单箭头箭标的控制则包括箭标形状的调整和箭头移动.将其应用于军事标图原型系统,应用结果验证了该模型正确可行.

Generation and Control of Non-Rule Symbol of Military Plotting System

Through conforming the reference point to make curve fitting and making certain point coordinate of the icon to be plotted, the generation models and the control models of non-rule military symbol were constructed. The structure control of the non-rule military included two types: the curve symbol and the arrow symbol. The former confirmed the two reference points of origination and terminal at the first place, which were given by the open curve, and then, ascertained the control axis of military symbol; the latter one, the controlling of single arrow symbol included the adjustment of the arrow shapes and the movements of the arrowhead. The system was used in military plotting system, which proved the validity and feasibility of the data model.
