针对飞行器可视导航中复杂机场空地环境多维要素动态交互可视化的难题,基于空地环境要素威胁语义统一的信息场模型,采用体绘制、面绘制与切片绘制混合的方法对机场近区域复杂多样的地形地貌、电磁和气象等威胁态势信息进行交互式动态可视化表达。以某机场的典型模拟数据为例,实现了威胁态势的动态交互可视化,验证了该方法的实用性和有效性。
針對飛行器可視導航中複雜機場空地環境多維要素動態交互可視化的難題,基于空地環境要素威脅語義統一的信息場模型,採用體繪製、麵繪製與切片繪製混閤的方法對機場近區域複雜多樣的地形地貌、電磁和氣象等威脅態勢信息進行交互式動態可視化錶達。以某機場的典型模擬數據為例,實現瞭威脅態勢的動態交互可視化,驗證瞭該方法的實用性和有效性。

Aiming to solve the problem of aircraft visual navigation in complex dynamic multidimensional factor airport environment interactively, by using volume rendering, surface rendering and slice drawing method ,interactive dynamic visualization expression is realized. Taking the typical simulation data of a certain airport as an example, the method achieving the threat field dynamic interactive visualization has been verified, and the practicability and effectiveness of the method has been approved.
