摘要

针对地面时敏目标的运动特性,介绍了航空时敏制导炸弹的组成和功能并分析了系统中的关键技术。提出了一种时敏目标的快速捕获与跟踪算法,在具有CUDA架构的图形处理器GPU上加以编程实现并采用KD树搜索算法进行了特征点间的匹配。最后在Geforce240MGPU上对算法进行了测试,试验结果表明:在480×240像素的图像上进行目标的搜索与匹配,系统运行时间只有0.12s,比目前在CPU上所实现的算法在快速性上提高了20多倍,验证了系统的实时性和可行性。

Abstract

According to the kinematic characteristics of time-critical targets on the ground, this paper introduces the composing structure and function of aerial time-critical guided bomb and analyzes key technologies of this system. A fast detection and tracking algorithm of time-critical targets is proposed which was implemented on a GPU with CUDA architecture, the KD-tree searching algorithm is also utilized for matching between features. Finally, the proposed algorithm is programmed on a Geforce 240M GPU, the test result shows that only 0. 12s is cost for object tracking and matching on a 480 × 240 image, which is 20 times faster than related implementation on CPU, which then testifies that the proposed system is reasonable and real-time.

Key words： object-critical target; guided bomb; adaptive control; object tracking; GPU
