对国产和进口两种风挡玻璃进行了鸟撞实验。实验中得到风挡玻璃对称中心线上多点位移时间曲线及风挡玻璃表面的应变时间曲线。 - For bilateral symmetry objects , the techniques on symmetry - point detection and symmetry - axis extraction are presented based on harmonic conjugation relationship . for rotated symmetry objects , the techniques on rotated units description and rotated symmetry center extraction are presented based on center invariants of objects . further more , by using 3d invariants and 2d projective transformation , an approach to recover shape from part symmetry objects is realized on some conditions
( 3 )深入分析了2d对称性目标透视成像的几何特点，将共点四线交比用于目标轮廓上的关键点的特性描述中；利用调和共轭关系，提出了一种针对左右对称型目标的对称点检测和对称轴提取的算法；利用交比关系构造了目标的形心不变量，提出了一种针对旋转对称型目标的旋转对称单元判定、旋转中心提取的算法；进一步利用3d不变量和2d射影变换，实现了一定条件下的对称性目标的形状恢复技术。
