The present invention is in step (1), and pick-up unit is checked through after the foreign matter that checks in passage by the travelling belt of pick-up unit, foreign matter to be taken to and cleans out after checking channel outlet.
The described image of step of the present invention (3) is processed one or more that comprise colour/white and black displays, image inverse, edge enhancing, image partial enhance, high penetrating power reinforcement, the reinforcement of low penetration power, blast/subtract secretly, image amplification and gray scale scanning.Below specifically introduce above-mentioned several image processing method formulas.
1, colour/white and black displays: coloured image is 4 color images, and along with the increase of X ray absorptivity, colour is changed to blueness by orange, and the object that is difficult to penetrate represents with black.Black white image has 256 grades of gray scales, by black to pure white gray level display.The image-region of whiter (gray scale is larger) represents that this object area is lower to the absorptivity of X ray, and namely more ray penetrates.The different object of absorptivity is corresponding to different gray shade scales.As required, the pick-up unit main frame can carry out the demonstration conversion of coloured image and gray level image, to obtain the concrete image information of article to be checked.
2, image inverse: in image shows, generally the object of X-ray high-absorbility is shown as aterrimus, the low absorptivity object is shown as brilliant white.In highlighting demonstration, just in time opposite.As required, the demonstration that the main frame of pick-up unit can carry out positive negative film is switched like this, and less or thinner high-density objects (as tinsel) will become more clear.
3, the edge strengthens: when needs carried out further interpretation to object edge, pick-up unit can highlight the object edge in image, was more conducive to the operator and distinguished different objects.
4, image partial enhance: blast is carried out in zone darker in image processed, make the clear demonstration of object that is hidden in thick object back, and normal image-region is unaffected.Pick-up unit control chart picture switches between normal demonstration and local enhancement demonstration automatically.
5, high penetrating power is strengthened: the regional luminance that penetration power is strong is brighter, and contrast is less, and zone that will be brighter shows with a suitable contrast, show that clearly high penetrating power is regional, but the normal region is affected simultaneously, and contrast reduces.
6, low penetration power is strengthened: the regional luminance that penetration power is low is darker, is difficult for observing, and this zone blast is improved this regional contrast, clearly shows this area image, but the normal region is affected simultaneously, and contrast reduces.
7, blast/subtract is dark: make screen intensity increase/subtract secretly, original dark regional clear demonstration when brightness increases, subtract when dark original bright regional dimmed, the stereovision increase.
8, inorganics highlights: the true colours of Recovery image during the effect of this processing, and eliminate all and be carried in treatment effect on this image.
