Patent number: 11974595Abstract: A method for testing burning performance of a dark-colored cigarette using a dark-colored cigarette paper is provided. The dark-colored cigarette paper has a grayscale less than 255. The method includes: simulating, by a robotic arm, a cigarette smoking process and environment; acquiring, by a full-vision camera system, an image of a burn line and ash column region of the dark-colored cigarette; and analyzing a burning performance indicator of the dark-colored cigarette according to coordinate information of the burn line and ash column region. The method is based on a surface reflection characteristic of the dark-colored cigarette paper and a principle of optical reflection to light and highlight an edge of the dark-colored cigarette sample by a light source at a certain angle from a side. In this way, the method forms a chromatic aberration to localize the dark-colored cigarette sample, thereby testing the burning performance of the dark-colored cigarette sample.Type: GrantFiled: September 20, 2022Date of Patent: May 7, 2024Assignee: CHINA TOBACCO YUNNAN INDUSTRIAL CO., LTDInventors: Han Zheng, Jianbo Zhan, Hao Wang, Zhenhua Yu, Jiao Xie, Xu Wang, Ying Zhang, Tao Wang, Baoshan Yue, Tingting Yu, Jiang Yu, Liwei Li, Jing Zhang
