Research on Segmentation of UAV's IR Cooperative Target Based on Machine Vision
摘要
Abstract
In the problem of cooperative target segmentation for the landing of unmanned aerial vehicle (UAV), the segmentation results of the double Otsu algorithm and maximum entropy algorithm are unsatisfactory when the target accounts for the image less than 0.2%. In order to promote the effects, an adaptive region growing method is proposed. Firstly, the pixel number of the cooperative target is set through the estimated distance between airborne camera and the landing target. Secondly, N brightest points of the image are found out automatically utilizing the characteristics of IR images. Then, the geo- metric center of the N brightest points is set to be the seed point. Finally, the terminal principle is determined by the statistical properties of histogram. The experimental results show that this method is better than the common segmentation methods, such as double Otsu and maximum entropy method.关键词
