Problems solved by technology
[0004] Digital scanning equipment is a series of systematic equipment that integrates scanning imaging, image digital retrieval, image recognition, and film-aided film evaluation. It has developed into a process of measurement evaluation. Therefore, in addition to meeting the standard requirements, the equipment also needs to be calibrated or identified. Due to its frequent use, it is necessary to frequently check the equipment during the period. At present, the identification and identification of the equipment meeting the standard requirements is through relevant computer equipment. Completed, it is more difficult for on-site inspectors to operate

Embodiment Construction
[0032] In order to make the objects, technical solutions and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and examples. It will be appreciated that the specific embodiments described herein are intended to explain the invention and is not intended to limit the invention.
[0033] See Figure 1-3 As shown, the present invention provides a method for producing a sensitivity verification piece for a backsheet scanning instrument, and is designed to meet standard requirements according to the photosensitive characteristics of the radiographic film, and produce a density region and a resolution recognition area and different values. The size line verifies the film, simply a simple operation of the film scanner, that is, the scanning instrument will compare the scanned identified original film with the digitized verification film to determine whether the standard requirement is met, and the confir...

Abstract
The invention discloses a manufacturing method of a sensitivity verification sheet for a negative film scanning instrument, and the method comprises the specific steps: drawing a standard sheet schematic diagram, printing the standard sheet schematic diagram on a film carrier, and carrying out the preprocessing of the standard sheet schematic diagram to make a standard sheet template; a resolution ratio comparison area and a blackness identification area are formed on the standard film, transverse lines, longitudinal lines and circular coils are formed in the resolution ratio comparison area, and a blackness zone is formed in the blackness identification area; and in a dark environment, the plane light source irradiates the standard film template, the light penetrating through the standard film template exposes the standard film through the lens, and the standard film is developed, fixed, washed and dried to obtain the verification negative film. And comparing the scanned and identified digitalized original negative film with the verification negative film through a scanning instrument so as to judge whether the standard is met or not, and meanwhile, enabling the manufactured verification negative film to be widely applied to the calibration and verification of the scanning instrument for field detection.
Description
Technical field [0001] The present invention relates to the technical field of the film production, and more particularly to a method of fabricating a sensitivity verification piece for a backsheet scanning instrument. Background technique [0002] Industrial ray detection is an important testing means of current industrial installation engineering quality inspection. This method is due to its intuitive, reliable, sensitivity and reliability in industrial detection, but this method has a lot of shortcomings, first engaged in radiography. The film needs to have a high professional technology level. Secondly, different types of defects have higher similarity after imaging, so that the results of the evaluation personnel have large extent to which the evaluation results are different. [0003] The general medium-sized chemical device or long-distance pipeline project detects the number of tens of thousands to hundreds of thousands, and its ray detection is large, preservation and tr...
