Permeability Detector Based On The Embedded Image Processing Research

At present, tobacco industry use various measure to make great efforts to cut down the smoking group entering amounts to cigarette middle tar wading across in course of, reduces the damage that the health having a smoke to them brings about.Among them, that amounts are one technology new and developing is being taken seriously by tobacco job step by step since Punching Shui Song paper cuts down smoker sucking in to tar coming paper by being put into use, the porocity is to owe one item key of industry an index since Punching Shui Song paper applies to but then. Therefore, already become the industry research hot spot by the fact that the degree applying various technology fighting each other Punching Shui Song paper porocity carries out accurate detecting. The main body of this book is relied on checking the main current that electron industry develops at present, setting up having suggested that one kind of the porocity owing to implanting the dyadic image treatment technology's checks an instrument. Systematic merit shows detecting mainly in several the following aspect:(1) Measure result precise. This detecting system gradation by fighting each other Punching Shui Song paper is algorithmic, can will measure value error under the control of that the breathe freely coming out spends finally within 3%.(2) Handle simply, the main body of this book design fight Punching Shui Song paper be offline measurement, so-called offline measurement right away need manpower general kind paper readjust oneself to a certain extent arrive at check system CCD camera shooting front use acquisition kind paper image data. After requiring that the manpower finishes setting appearance paper free in system press down the button beginning being OK.(3) Take time few. In general, detecting system detecting one frame of appearance paper needs 10 seconds or so, but this system detecting one frame of appearance paper needs 4～5 seconds.(4) prospects well. The development of embedded system is rapid, compares with other examination systems, embedded system extremely to have potential affirms that the first reaches the request that online check spends since porocity of Punching Shui Song paper.Surround the main body of a book priority and difficult point: Since Punching Shui Song paper image gradation handles proportion basis that the hole takes up on coming to calculate out decent paper of picture, have done the following job:(1) The parameter has carried out thorough analysis and the component selections type on every system usage component function. Have accomplished hardware module function and the connection between them base on digital image processing by embedded System(2) Base on embedded system porocity examination in the hardware foundation to complete software the design. Achieved adds Punching Shui Song paper image processing goal, and finally demonstrates thepermeability value on the digital tube.(3) The experiment having been in progress to the detecting system designing that studies, major factor, these factor checking accuracy and running a stability includes the ambient temperature and humidity etc. By the fact that the experiment has analysed the system affecting detecting detailedly. The summary having given out full text finally , the suggestion having suggested that one technology studies in a deepgoing way to this.
