摘要
根据光流法基本原理,推导了用光流信息求解相对位姿估计的数学模型,提出了一种基于特征点光流信息的相对位姿估计算法。用Pov-Ray软件生成的序列图像验证了算法的可行性,并用STK软件生成的卫星视频验证了算法的可行性和准确性。
A mathematical model of relative pose and altitude estimation was deduced based on the basic principle of optical flow method in this paper.A relative pose estimation algorithm based on feature point optical flow information was proposed.The feasibility of the algorithm was verified by using image sequences Pov-Ray software.The feasibility and accuracy of the algorithm were verified by using STK software to generate the satellite video.
