Description
Technical field
The utility model relates to a kind of pick-up unit, particularly a kind of digital automatic color measurement and color match system.
Background technology
Present color management technology is based on all that spectrophotometer carries out, this technology comparative maturity, and precision can meet the demands.But spectrophotometer costs an arm and a leg, and function singleness.The spectrophotometer (comprising software and hardware) that China uses has only Shenyang Chemical Engineering Inst to utilize external hardware all from external import, oneself has developed some softwares.The limitation that spectrophotometer exists comprises: the wet sample of energy measurement not, as coating etc.; The irregular sample of energy measurement not is as apple etc.; Can not carry out remote measurement and assessment; Outward appearance that can not the measurement target object; Texture features that can not the measurement target object; The frangible object of energy measurement not is as crisp biscuit etc.; Can only Measuring Object the color on surface certain a bit, the anti-interference of this moment is just very poor, promptly randomness is big.
Summary of the invention
The purpose of this utility model is for overcoming spectrophotometric measurement defective, increases multinomial other functions of color grouping, color emulation, texture analysis, multimetering, long-range assessment, and a kind of digital automatic color measurement and color match system is provided.
For achieving the above object, the technical solution adopted in the utility model provides a kind of digital automatic color measurement and color match system, include the lamp box of the standard sources that provides stable, wherein: above described lamp box, be provided with a hole, put into digital camera in this hole, the camera lens of described digital camera is the bottom in described lamp box downwards, be placed with colour atla or exemplar in the described lamp box, described digital camera is taken the information data of described colour atla or exemplar and is gone into main frame by digital camera by the USB oral instructions that are located on the main frame, and be presented at display that main frame is connected on.
Described lamp box is set to the open front open type.
Described lamp box choice criteria light source is a kind of among D65, TL84, UV, the F/A.
Effect of the present utility model is the main frame that this system utilizes high-precision digital camera, lamp box, high-resolution display and high configuration, can be under the illumination observing environment that can control fully, utilize contactless, can catch the color of measured target object and the outward appearance of two dimension or three-dimensional body exactly, be presented on the high definition screen that passes through calibration then or printout.This system has the function of selecting and obtain color data from the pixel of high-definition picture, also can be used for measuring very little (as pixel) or irregular image.By the standard format of storage, image and color data can be carried out simply on the internet, exchange apace.Compare with traditional spectrophotometer, the advantage of native system also shows the following aspects:
(1) function expansion: native system not only can be realized spectrophotometric colour examining function, and has multinomial other functions such as the color of comprising grouping, color emulation, texture analysis, multimetering, long-range assessment, recipe calculation.
(2) cost reduces: no longer use the high-accuracy spectrophotometer that leans on import fully, and be to use computing machine, digital camera commonly used at present, cost reduces greatly.
