摘要
大型飞行器因承受时变气动载荷经常发生动态弹性变形,其形态会对燃油效率、飞行安全和气动性能等产生重要影响。论文采用立体相机采集模型变化视频图像,使用环形编码标志点解决同名点的立体匹配和目标跟踪问题,重建各个时刻标志点三维坐标并对其运行轨迹进行跟踪,从而获取大型飞行器动态变形、应变分布等动态数据,开发出了动态测量系统并进行了应用实验。
The Dynamic deformation of large-scale aircraft in flight is notable and need be kept in the range of security. To quantify dy- namic deformation ,this paper used circular coded targets to solve the matching and tracking of the same target. After detection and matching of circular coded targets,three-dimensional coordinates of the targets in a series of time could be reconstructed. The ground simulation ex- periments shows that this method can be used for the dynamic deformation measurement of aircraft model. Compared to traditional methods this method has the advantage of accuracy, convenient and efficient.
