Abstract
The utility model discloses a spectroscopic color image color acquisition box, comprising a casing and a neutral diffusion inner container arranged in an outer casing; wherein a bottom of the neutral diffusion inner container is provided with a light source assembly, an object stage is arranged below the light source assembly, a top of the casing is provided with a digital camera used for acquiring a color image of a measured object; and the light source assembly is a multi-band light source assembly. The spectroscopic color image color acquisition box of the utility model can perform sampling for metamerism spectral reflection characteristics of the measured object.
Description
Technical field
The utility model relates to a kind of spectrum beam split chromatic image color vasculum.
Background technology
The body surface look is to be determined by selectivity, the spectral power distribution of lighting source and observer's the colour vision characteristic of object to reflection of light, transmission and absorption etc.People not only can also understand other character of object from the singularity that absorbs, reflects from object to the absorption of spectrum, the color that reflection characteristic is estimated them.Because material all has the selection absorption and the reflection characteristic of the spectrum of oneself, therefore changed the spectral range of incident light, can make object present various color.This also is the reason that has the metamerism look why, and metamerism is very important, a frequent problem that needs solution in colorimetry.
Coloured object that people see in the daily life generally is the metamerism look, especially in industries such as printing, printing and dyeing, coating, paint, plastics, drawing.When requiring to make the color identical with sample, if it is difficult will reaching spectral characteristic identical, the overwhelming majority is the requirement degree of metameris in the scope that acquires a certain degree.The color of different spectral characteristics can have identical appearance under what condition; The degree of quantitative evaluation metamerism how; The calculating " special metamerism index " that international CIE announced in September, 1971 changes the evaluation method of working flare and the evaluation method that CIE15:3 (2004) has increased " special metamerism index " change observer again, and its purpose all is in order to solve the quantitatively evaluating of coloured object metamerism.The instrument that can be used for the check of metamerism look at present is that object is placed in the inspection box of checking colors of multiple standards light illumination, carries out visual qualitative judgement, and its shortcoming is influenced greatly by observer's subjectivity, and error is high, and can not carry out quantitative analysis.So far still not having a kind of instrument of directly inspected object metamerism spectral reflection characteristic to can be the QC management provides practical and effectively detection by quantitative instrument or method.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming and defect that prior art exists; Can the spectral reflection characteristic of object to be detected metamerism be sampled and provide a kind of, thereby the spectrum beam split chromatic image color vasculum of sampled data is provided for the quantification detection that realizes the metamerism look.
For realizing above-mentioned purpose; The technical scheme of the utility model is to include casing and the neutral diffusion inner bag that is arranged in the outer case; The bottom of said neutral diffusion inner bag is provided with light source assembly; The below of this light source assembly is provided with articles holding table, and described casing top is provided with the digital camera that is used to gather the testee chromatic image, and described light source assembly is the multiband light source component.
Further being provided with is that the multiband light source component includes erecting frame, is arranged on a plurality of light sources on the erecting frame, and is arranged at and is used on a plurality of light sources carrying out the narrow band pass filter that printing opacity is chosen in the 300-830nm spectral wavelength scope.
Further be provided with is that described light source adopts the different capacity pulse xenon lamp that comprises ultraviolet light.Through this setting, to solve the different illumination different problems that produce of transmitance because of the optical filter of different spectral wavelength scopes.And can the gating pulse xenon lamp glittering time of moment, keep with the digital camera shooting synchronously, guarantee to take the photograph to such an extent that the image picture is clear, true and measure in the following institute of the consistent condition of the lighting level colorimetry that forms.
Further being provided with is that described erecting frame is square, and described a plurality of light sources and narrow band pass filter distributed and arranged thereof are on four limits of erecting frame.
Further being provided with is that the oblique upper of a plurality of relatively light sources and narrow band pass filter thereof is provided with the corrugated diffuser plate on the described erecting frame, and the sidepiece of described erecting frame is provided with the arc diffuser plate corresponding with the diffusion light path of corrugated diffuser plate.
The top that further setting is described neutral diffusion inner bag is provided with diffusion shell.
The top that further setting is described casing is provided with lifting support, and this lifting support is provided with the light harvesting hole, and said digital camera is fixedly supported on the lifting support, and the camera lens of digital camera and the corresponding setting in light harvesting hole.
The utility model is controlled each light source of multiband light source component through modes such as computing machine or control circuits; Form band by every interval 20nm or the identical wavelength interval of 40nm; Therefore can be to the mode that object under test carries out the spectrum beam split sampling of taking pictures respectively; Adopt computer technology that above-mentioned each image picture is synthesized; Can provide image coloured image and the colorimetry technical parameter of object under various criterion working flare condition, for the quantification that realizes the metamerism look detects sampled data is provided, and then can effectively solve the metamerism look of object detection.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
