Image acquisition device of smoking path simulation system

Abstract

The invention relates to an image acquisition device of a smoking path simulation system, which belongs to the technical field of cigarette detection equipment. The device comprises a manipulator, a frame body which is fixedly connected with the working end of the manipulator and is provided with N supporting rods, N cameras which are fixedly connected to the different supporting rods respectively, and N supplementary lighting lamps which are fixedly connected to the different supporting rods respectively, wherein lenses of the cameras face the working end of the manipulator, and light sourcesurfaces of the supplementary lighting lamps face the working end of the manipulator. N is greater than or equal to 2. According to the device, the supplementary lighting lamps are utilized; images are dynamically collected in real time through the cameras under the action of the smoking path of the manipulator; and the cigarette combustion ash wrapping characteristic detection precision is effectively improved. The device is suitable for image acquisition of smoking path simulation systems of various cigarettes.

Description

technical field [0001] The invention belongs to the technical field of cigarette detection equipment, and in particular relates to an image acquisition device of a smoking path simulation system. Background technique [0002] When studying the ash-coating performance, gray color, and ash deviation degree of cigarette burning, it is necessary to collect the image state of the entire burning process of the cigarette. Comprehensive, accurate and objective collection of cigarette burning images is the key to accurate detection and analysis of the above indicators. Facts have proved that due to the overlap surface at the burning end of the cigarette, and the influence of each cigarette due to factors such as the filling density of shredded tobacco and the difference in the structure of shredded tobacco, there will inevitably be large differences and fluctuations in the observation conditions of cigarettes at various angles when they are burning.

Facts have proved that due to the overlapping surface of the burning end of the cigarette, and the influence of factors such as the filling density of the shredded tobacco and the difference in the structure of the shredded tobacco, each cigarette will inevitably cause large differences and fluctuations in the observations of the cigarettes at various angles when they are burning.

[0003] At present, for the detection of cigarette combustion-related indicators, the method of collecting images by taking pictures on one side is usually used for image analysis. Due to the existence of the above reasons, the detection value of each cigarette lacks objectivity and high accuracy.

Of course, in order to avoid the above-mentioned disadvantages of single-sided photography, the method of avoiding the mouth of the cigarette or increasing the test sample size was also adopted during the experiment. This may slightly improve the test results, but it still cannot fundamentally solve the problem , can not realize the objective collection of full information of cigarette samples, at the same time, it also reduces the work efficiency, and also requires the preparation of a large number of parallel samples

[0004] In addition, the current research on some relevant indicators of cigarette combustion performance uses static fixed-point shooting methods for image acquisition, and there is no dynamic image acquisition method that simulates the human body's puffing path process.

Therefore, there is no better image acquisition device and equipment for studying the combustion performance state of cigarettes in the process of human body smoking.
