Patent number: 11670007Abstract: A device and a method for detecting cigarette fly ash by a gray-scale difference based on machine vision (MV) are provided. A manipulator holds a cigarette as a detection sample to simulate a human smoking action, and multiple groups of cameras track a simulated smoking process of the detection sample synchronously in real time. It is determined whether fly ash appears based on a gray-scale difference of burning ash columns, produced without being subjected to flicking, in acquired images. A fly ash area of the burning ash columns of the cigarette is calculated by an area with the gray-scale difference of the burning ash columns of the cigarette in two sequential images of the burning ash columns of the cigarette, and a fly ash amount is further determined. The detection of the amount of fine fly ash is converted into the detection of the gray-scale difference.Type: GrantFiled: January 21, 2021Date of Patent: June 6, 2023Assignee: CHINA TOBACCO YUNNAN INDUSTRIAL CO., LTDInventors: Han Zheng, Jianbo Zhan, Ying Zhang, Hao Wang, Tao Wang, Ying Zhang, Zhenhua Yu, Xu Wang, Jiao Xie, Tingting Yu, Liwei Li, Haiyan Ding, Yao Yu, Li Jiang, Shuai Yang

Patent number: 11445746Abstract: A robotic arm includes a base, a first robotic arm, a second robotic arm, a robotic hand and a cigarette holder connected in sequence. The cigarette holder includes a cigarette insertion hole and a cigarette smoking tube. The cigarette smoking tube is connected to a smoking simulator. The robotic arm further includes at least one air exhausting hole. The air exhausting hole is located around the cigarette holder and communicated with an air exhauster through an air exhausting pipe. The robotic arm swings to control the cigarette holder to carry a cigarette from a smoking position to an ash flicking position. Airflow is formed near the air exhausting hole by means of air exhaustion, so as to simulate influences of a wind speed in an outdoor environment on the columnar ash in the cigarette smoking process of the human body.Type: GrantFiled: January 21, 2021Date of Patent: September 20, 2022Assignee: CHINA TOBACCO YUNNAN INDUSTRIAL CO., LTDInventors: Han Zheng, Ying Zhang, Hao Wang, Jianbo Zhan, Zhenhua Yu, Jiao Xie, Xu Wang, Geng Li, Tao Wang, Tingting Yu, Liwei Li, Haiyan Ding, Baoshan Yue, Jiang Yu, Jing Zhang
