目的 研究卷烟不同内衬纸对光的敏感程度，为优化机器视觉检测精度以提高卷烟的包装质量提供参考依据。方法 基于机器视觉技术，通过RGB和HSV颜色模式对不同颜色、类型内衬纸的光学反应参数进行测试，采用方差分析对光敏性进行差异显著性分析，确定显著程度后再进行相关性分析，得出不同内衬纸与光敏性的关系，并验证缺陷内衬纸的光敏性。结果 不同颜色、类型内衬纸间的光敏性均存在显著性差异，其中R对颜色的光敏性影响最大，且与颜色呈显著正相关，光敏性强弱依次为：红色>浅金色>银色>金色。V对类型的光敏性影响最大，且与类型呈显著正相关，光敏性强弱依次为：压花复合铝箔型>普通转移型>直镀铝箔型>复合铝箔型>镭射型>真空镀铝转移型。结论 不同卷烟内衬纸的光敏性均存在差异，在实际生产中，企业可针对不同品牌内衬纸优化光敏性范围，通过调整光学参数R, V进行缺陷内衬纸的判断与剔除。

The work aims to study photosensitivity of different cigarette liners and provide a reference for optimization of the accuracy of machine vision detection to improve cigarette packaging quality. Through RGB and HSV color modes, optical reaction parameters of different colors and types of liners were tested based on machine vision, and significance of difference was analyzed by regression variance analysis. After confirming the degree of significance, correlation analysis was performed to obtain the relationship between different liners and photosensitivity, and verify the photosensitivity of defective liner. There were significant differences in photosensitivity between cigarette liners of different colors and types. Among them, R not only had the greatest influence on the photosensitivity in different colors, but also had a significant positive correlation with colors. Its photosensitivity was as follows: red>light gold> silver>gold. V not only had the greatest influence on the photosensitivity in different types, but also had a significant positive correlation with types. Its photosensitivity was as follows: embossed composite foil type>ordinary transfer type>direct aluminum-plated foil type>composite foil type>laser type>aluminum vacuum transfer type. There are differences in the photosensitivity of different cigarette liners. In actual production, companies can optimize the range of photosensitivity for different brands of cigarette liner, and adjust optical parameters R and V to judge and reject defective liner.
