摘要
针对稳瞄惯导一体化系统在动态情况下,用人眼去判读它的稳瞄精度的实时性和准确性都比较差。为了解决此问题,提出了一种基于DSP+FPGA的图像检测技术的检测稳瞄精度的方法,并结合图像处理实现了对目标的高精度判读且可以计算目标在各帧图像中的坐标,从而达到了对稳瞄精度检测的目的。结果表明:检测精度可达到0.05mrad;整个实时检测系统具有良好的稳定性,能同时适用于实验室和靶场环境。
Interoperating the sight-stabilizing accuracy in dynamic case by human eyes, the sight-stabilizing INS integrated system has a bad real-time capability and a low accuracy. In order to solve thus problem,the method detecting the sight-stabilizing accuracy based on the image inspecting technique is proposed. And combining the image process technology into it,we realize the high accuracy interpretation as well as obtain the coordinate in two axes of the image each frame,and then achieve the purpose for the high accuracy and good real-time capability. The result shows that the accuracy is up to 0.05 mrad and the detection system has so good a stability that can adapt to the environment of the laboratory and target range.
