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
