摘　　要：颜色空间转换效果直接关系到数码印花的质量,针对传统颜色空间转换存在的色差较大的问题,提出一种激光成像雷达技术下数码印花颜色空间转换方法。该方法分为两部分,前一部分是激光成像雷达技术获取印花原稿图像并利用邻域平均法去除处理去除图像中的散乱点云数据,后一部分将印花原稿的RGB颜色空间转换到Lab空间,再利用神经网络模型将转换到CMYK颜色空间。针对该方法展开仿真测试,结果表明:应用本方法后,图像色差在0.22~0.37之间,结构相似性指数在0.88~0.95之间,转换时间在21.9 s~25.6 s之间,说明该方法的转换效果更好,转换后更能够保证颜色与印花原稿颜色的一致性,在提高转换效率的同时降低了颜色偏差。The effect of color space conversion is directly related to the quality of digital printing.In response to the problem of large color difference in traditional color space conversion,a color space conversion method for digital printing using laser imaging radar technology is proposed.This method is divided into two parts.In the first part,the laser imaging radar technology is used to obtain the printed manuscript image and remove scattered point cloud data from the image using neighborhood averaging.In the second part,the RGB color space of the printed manuscript is converted to Lab space,and then converted to CMYK color space using a neural network model.A simulation test was conducted on this method,and the results showed that after applying the method proposed in this paper,the image color difference was between 0.22 and 0.37,the structural similarity index was between 0.88 and 0.95,and the conversion time was between 21.9 and 25.6 seconds.This indicates that the conversion effect of this method is better,and it can better ensure the consistency between the color and the original printing color after conversion,while improving conversion efficiency and reducing color deviation.
