摘要: 实现民航客机的飞机油箱建模,提出对油箱的油量传感器示数的姿态误差进行修正的算法.建模过程基于二维限定Delaunay三角剖分和插值,生成油箱的表面.利用油量传感器错误示数和当前飞行姿态角,利用油箱表面三角网格,将油箱内含油体积进行三维三棱柱剖分和三维四面体剖分.计算四面体体积之和求得油箱正确的含油量.与当前正在使用的切片算法在效率和使用范围方面进行深入比较与分析.实现民航客机油箱三维建模,并且利用已建立的模型修正其油量传感器示数姿态误差.算法优于切片算法.

Abstract: The algorithm of modeling civil airliner gasoline tanks and modifying the attitude error of tank volume sensors was provided. Tank surface was generated with triangle mesh based on two-dimensional Delaunay triangulation and interpolation. Using the wrong result of gasoline volume sensors, current attitude error and surface triangle mesh, logical prisms and tetrahedrons were generated. The correct volume was calculated with total volume of prisms and tetrahedrons. The algorithm was compared with the current slice algorithm in efficiency and applicability. Solving the three-dimensional modeling of civil airliner tank and the modification of attitude error of tank volume sensors with that finished model, this algorithm is more effective and efficient than slice algorithm.
