Characterizing cigarette combustion dynamics using a vision-based 3D circumferential measurement and extraction system

The precise measurement and extraction of characteristic parameters during the cigarette combustion process is paramount for a comprehensive understanding and efficient regulation of cigarette combustion. In this work, a novel three-dimensional extraction method for characteristic parameters in cigarette combustion has been proposed. The method overcomes the limitation of the traditional single camera to obtain image information due to incomplete field of view, and obtains the complete information of the cigarette combustion process by arranging synchronized cameras distributed around the circumference. The dynamic characteristic parameters of cigarette combustion, including burning line width, burning line uniformity and burning rate could be determined in real-time accurately. To verify the accuracy, the method has been applied to three different types of cigarettes. Results showed that the 3D reconstruction-based method can provide more accurate and reliable data for research in the field of cigarette combustion, offering foundational resource for further research into constituent release during cigarette combustion.
