摘　　要：在ICF物理实验中,靶定位精度直接影响打靶的成功率。靶定位系统包括两套CCDs和一 个多维调整架,两套CCDs从不同的视角得到靶的图像。在计算机中用边缘提取的方法分析它们的特征值,综合两个CCDs的特征值计算靶的空间坐标,它与基准点的偏差就等于靶的调整量。该系统采用了前照明,实验测得它的定位精度为4靘。In ICF physical experiment, target-positioning accuracy directly affects the success rate of target hitting. A target positioning system consists of two sets of CCDs and a multi-dimension adjustment support. The CCDs acquire the image of target from different viewing angles. Their characteristic values are analyzed with edge extraction method in a computer. The spatial coordinate of target is calculated by integrating the characteristic values of two CCDs. Its deviation from the reference point is equal to the target adjustment quantity. The forward illumination is applied to the system. Its positioning accuracy measured in experiments is 4 μm.
