摘　　要：为提升漆画修复效果,使修复细节更为精细,研究了基于激光全息技术的漆画无损修复方法。利用激光全息技术构建参数一致的破损监测模型,跟踪破损区域获得该区域空间坐标,利用多项式函数拟合获取破损区域曲线函数,对函数提取破损区域特征进行求导,从而确定破损区域坐标;根据该坐标使用改进Criminsi算法改进优先权函数、有限顺序判断准则,将正则化因子加入到置信项和数据项中,加权求和优先|权函数,利用数据项优先修复像素点,完成漆画破损区域修复。结果表明,该方法能够准确定位破损区域坐标,高效去除图像中噪声,修复后保证漆画原有细节,修复整体均方误差较低,保持在30以下,能够获得良好的修复效果。In order to improve the repair effect of lacquer painting and make the repair details more detailed, this paper studies the nondestructive repair method of lacquer painting based on laser holography. The laser holography technology is used to construct the damage monitoring model with the same parameters, track the damaged region to obtain the spatial coordinates of the damaged region, obtain the curve function of the damaged region by polynomial function fitting, extract the features of the damaged region by the function derivation, so as to determine the coordinates of the damaged region. According to the coordinate, the improved Criminsi algorithm is used to improve the priority function and the criteria of finite order determination, regularization factors are added into the terms of confidence and data, the weighted sum of the priorities function, the data terms are used to repair the pixels, and the damaged areas of paint are repaired. The results show that this method can accurately locate the coordinates of the damaged area, effectively remove the noise in the image, guarantee the original details of the paint painting after repair, and maintain the overall mean square error below 30, thus achieving a good repair effect.
