Technical field

The utility model relates to a kind of cigarette product presentation quality inspection technology, especially a kind of device that utilizes image technique that tobacco bale or appearance of tobacco rod are detected, specifically a kind of device that improves plume tobacco bale image detection image quality.

Background technology

At present, along with the continuous development of computer technology and image processing techniques, it is quite general to utilize the CCD camera that the presentation quality of plume on the manufacturing line or tobacco bale is carried out online detection.And will obtain for the image of Computer Automatic Recognition except needs use special quality CCD camera, also needing is that the CCD camera is equipped with suitable light source.And conventional lighting sources adopts the general lighting light source mostly, even this common lighting source can be adjusted its lumen by light adjusting circuit, but its color can't be adjusted.For tobacco packaging machine, the external packing color of plume on the baling line or tobacco bale can change according to the difference of kind, therefore when bigger variation takes place in the color of external packing, if adopt identical light source irradiation on plane was seized, will cause because the pattern on tested plume of illuminating ray or tobacco bale surface absorbs or reflection causes illuminance too small or excessive, cause not fogging, influence the accuracy that computing machine is judged, also limited the adaptive capacity of manufacturing line, this has not still been had good solution at present the cigarette kind.

Summary of the invention

The purpose of this utility model is to cause institute's image definition of taking the photograph not enough because lighting source can't adapt to its variation when changing at plume in the existing cigarette-packaging machine or tobacco bale outward appearance, easily cause the problem of erroneous judgement, invent a kind of detecting device that improves plume tobacco bale image detection image quality.

The technical solution of the utility model is:

A kind of device that improves plume tobacco bale image detection image quality, it is characterized in that it mainly is made up of primitive colours LED light source 1, ccd video camera 2 and computing machine 3, the driving circuit 4 of primitive colours LED light source 1 links to each other with light adjusting circuit 5, light adjusting circuit 5 is controlled by the computing machine 3 that light modulation or color matching software are installed, and primitive colours LED light source 1 and ccd video camera 2 are installed in the same side or the ipsilateral not of the plane was seized of tested plume or tobacco bale simultaneously.

The place ahead of described primitive colours LED light source 1 is equipped with even tabula rasa 6.

The beneficial effects of the utility model:

1. the utility model is owing to can adapt to the change color of tobacco bale or tobacco bale automatically, the brightness (lumen and light quantity) of automatic compensation illumination, so image optimum that the CCD camera is absorbed, for the automatic differentiation of computing machine provides desirable picture, help further improving the accuracy that image detection is differentiated.

2. the utility model helps improving the flexibility of existing cigarette pack manufacturing line, makes it to adapt to the outward appearance of the plume or the tobacco bale of various different colours, more need not to change light source into the plume of Different Package or tobacco bale detect, and can save production cost.

3. color matching of the present utility model and light modulation can adopt existing proven technique to be realized, cooperate existing powerful Computer Processing function simultaneously, make that the color matching light modulation is very efficient and convenient, can in seconds finish relevant color matching, light modulation process according to the outward appearance of plume on the manufacturing line or tobacco bale.
