摘要:
针对无人机低空采集的高分辨率视频特点,提出了一种无迹卡尔曼滤波和KLT(KanadeLucasTomasi)匹配算法相结合的特征点跟踪算法。首先,利用无迹卡尔曼滤波在相邻帧中进行特征点预测,以确定匹配范围;其次,根据KLT匹配算法对特征点进行跟踪,以得到的匹配结果作为观测值;最后,通过卡尔曼增益修正得到特征的准确位置。针对建筑物、草地等不同类型视频数据集的实验结果表明,该算法可以得到精确的特征位置。
Abstract:
According to high resolution video feature of unmanned aerial vehicle(UAV) low acquisition,this paper proposes a feature points tracking algorithm combined uncented Kalman filter(UKF) and KanadeLucasTomasi(KLT).Firstly,the algorithm uses UKF to predict feature points in the adjacent frames to determine the scope of the match.Secondly,the algorithm tracks feature points according to KLT matching algorithm.The results are seen as observed value.Finally,the accurate position of the feature points through the kalman gains correction.The experiment results for buildings,glassland and other different types of video data set show that the algorithm can get accurate feature location.
