一种用于弹道终端飞机红外图像机轴检测的算法
Algorithm of airplane axis detection for infrared images of airplane at missile terminal
摘要
Abstract
Based on the infrared imaging guidance system,the attitude recognition technology of target airplane was studied by using image information of infrared imaging seeker on the back ground of guidance integrated fuzing(GIF)technology. The skeleton of a target airplane image is extracted by a thinning algorithm,and then an algorithm which combines the improved Hough transform with the least square fitting is proposed to detect the airplane-axis. The preliminary detection is carried out ac-cording to the robust and heuristics-free characteristics of Hough transformation to determine image regions where a line may exist. The least square fitting is used to confirm the accurate parameters of feature point regression straight-line in a straight-line re-gion. The simulation results show that the algorithm has improved the detection rate and detection precision of airplane's axis, decreased the requirement of resolution to Hough transformation,and reduced the space demand of the algorithm.关键词
