Study on Grey Benchmark Adjustment and Visual Measurement of Cigarette Combustion

The color of cigarette paper and its ash after combustion is one of the most intuitive evaluations for consumers. In order to solve the problem that the judgment of machine vision is not unified and there is no standard reference, an objective and accurate method of cigarette combustion gray benchmark adjustment and visual measurement based on ceramic stick was are provided in this paper. Through multi-faceted simultaneous shooting of a single cigarette in the state of static combustion or smoking, real-time image tracking acquisition is carried out to complete multi-faceted full vision acquisition of cigarette sample combustion. The experimental results show that there are some standard deviations in the three angles, and the method of taking the mean value reflects the gray of cigarette combustion to the greatest extent. Using ceramic bar as reference to calibrate cigarette gray, real-time acquisition and data processing can accurately and objectively determine and compare the test samples, which could be applied for scientific statistics and research. The uniform lighting design of multiple LED light sources ensures the quality of the collected images.
