Ming Cui, Zhiyong Wu, Yonggang Cao · 2015
Strapdown seeker connect the sensor fixed on the projectile, through a large field of view to ensure the effective of target detection, in order to solve the high frame rate digital image processing and target recognition tracking problem, design a kind of based on FPGA + DSP architecture is applied in the strapdown seeker image tracking scheme.The scheme adopts full digital interface, realize the Cameralink digital image data real-time acquisition, preprocessing, target tracking, character overlay, video output, etc.In view of the seeker workflow, a target tracking algorithm is designed based on feature, through digital simulation and embed implementation.Results show that the tracker can overcome the rotation and expansion of the target, complete right on target tracking, processing speed can ensure the real-time processing of target tracking in the 20 ms.
