| 摘 要： | 提出了一种新的基于对应直线估计飞行器接近角的方法,对线性方法作归一化变换以提高算法的鲁棒性。用至少4组对应直线计算两图像间的单应矩阵。用序列图像间的单应矩阵估计接近角,无需着陆目标已知。模拟实验验证了算法的可行性。

| Abstract: | A new algorithm based on correspondence lines for aircraft approach angle estimation was presented in this paper.The algorithm was normalized to improve the robustness.The homography between two images was estimated using the least four groups of relative lines.For using homography of image sequences to estimate approach angle,the algorithm was in no need to know the target.Experimental results showed that this algorithm was validated. |
