摘要
针对靶场导弹零时信号检测的需要,讨论了现有检测方法的局限与不足,提出了利用高帧频摄像系统及图像处理技术进行导弹零时信号非接触检测的方法,即将特征区域的垂直投影变化作为目标垂直上升的位移变化,当位移超过一定阈值时给出零时信号。对实际情况中不同因素影响的图像进行了模拟实验,实验结果表明:该方法能够在距离目标300m外有效地检测出1cm的位移变化,处理时间在10ms之内,能够实时可靠地给出零时信号。
A novel method based on image processing technique algorithm is proposed to measure the zero time of launching.The paper analyze the disadvantages of the current methods.The non-contact measurement based on high frame rate camera and image processing technique is proposed,in this way,the location of horizontal projection of the feature area is considered to be the horizontal displacement of the target.When the displacement is larger than the threshold,the zero time is triggered.According to the actual situation,the paper carries out an experimental simulation under different factors.The results reveal that,the algorithm can provides real-time and reliable zero time by detecting 1cm movement at a distance of 300 m in 10 ms.
