Description
Technical field
The present invention relates to a kind of cigarette assay method, more particularly to a kind of cigarette burn rate assay method.
Background technology
Smoking machine, which is that tobacco business is distinctive, to be used to simulate people's smoking process and traps causedization during cigarette burning
Learn material, then the equipment through row analysis.Specification difference, the difference of raw material due to cigarette in actual application can cause
In smoking process, the Smoldering rate and suction fuel speed of cigarette can be different, it is possible to cause smoking machine trapping effect to have
Difference, so the burn rate of cigarette is also the direction of industry concern research.Present tobacco business owes no instrument can be
The burn rate of complete monitoring cigarette in smoking machine experimentation.With the development of image processing techniques, we can utilize height
Fast video camera shooting record cigarette burning whole process, while image is handled in real time, it is possible to calculate the combustion of cigarette
Burn speed.
The content of the invention
, should it is an object of the invention to provide a kind of cigarette burn rate assay method in order to solve above-mentioned technical problem
Method gathers the signal of smoking machine suction by the change of cigarette overall process in videograph smoking machine smoking process,
The collection calculating cigarette that processing is carried out to image by Labview softwares with reference to the suction signal of smoking machine is glowed and the speed of suction fuel
