【摘要】 针对二三维环境下态势标绘中实时态势标绘要求,重点研究单箭头标绘和双箭头标绘,提出二维态势与三维态势联动表现的一体化操作和显示的中轴线约束标绘模型,提出一种中点算法模型的曲线拟合方法,便于控制曲线趋进度,可有效实现二三维环境下箭标的实时标绘,对态势标绘的推广应用具有借鉴意义。更多还原

【Abstract】 For the request of real-time situation plotting in both two-dimensional and three-dimensional environment,it presents the single arrow plotting and double arrow plotting which includes a central axis constraint plotting model that can display the performance of two-dimensional and three-dimensional linkage and an curve fit method based on the midpoint algorithm in control of the progress of the curve trend.The real-time plotting of arrow mark in two-or three-dimensional environment can be effectively realized by the model and algorithm.It can be used as a reference for the popularization and application of the situation plotting.更多还原
