中文摘要 | 为满足高功率激光驱动器光束自动准直的高精度和实时性要求,提出了一种快速高精度的自动准直目标定位算法。首先利用变结构元广义数学形态学边缘检测算法在充分提取图像边缘细节信息的同时抑制图像噪声的影响,然后采用拉格朗日多项式插值算法对圆目标轮廓进行快速亚像素定位,最后利用最小二乘拟合以及几何形心拟合的方法实现图像中光斑目标中心的精确定位。该算法在神光Ⅱ升级装置的光路自动准直中得以验证,实验结果表明八路预放光路准直时间小于3 min,主放光路准直时间小于7 min,主放输出光束近场准直准确度优于0.2%,远场指向准确度优于0.2(RMS)。 |
英文摘要 | To meet the requirements for high accuracy and real time performance of high power laser driver beam automatic alignment, a fast and precise center location method for target of high power laser driver beam automatic alignment is proposed. The specific characteristics of the target edge are fully extracted by using multiple structuring elements-based generalized morphological edge detection, while the influences of the noises on images are diminished. Then, the edge is quickly located in sub-pixel precision by adopting the Lagrange polynomial interpolation method, at last the center position of the spot target in image is accurately acquired by using circle fitting method based on least square fitting method and geometric centroid. This algorithm is verified in the ShenguangⅡ upgrade device, the alignment time of eight prelight roads is less than 3 min, and the alignment time of the main light path is less than 7 min. The main output of the near-field beam collimation accuracy is better than 0.2%, and the far field accuracy is better than 0.2(RMS). |
