Abstract
The invention relates to an automobile paint color blending system, which includes a material blending mechanism and a stirring mechanism, and also includes a high-definition camera, a sampling mechanism, a feedback mechanism and a regulating center. The high-definition camera, the regulating center, the material blending mechanism, the stirring mechanism and the sampling mechanism are connected successively. When the high-definition camera collects surface color information of an automobile awaiting paint repair, the regulating center analyzes the information to obtain a crude toning formula of the color and generates a compensation formula through a feedback process to control the material blending mechanism to provide paint color master batches for the stirring mechanism according to a corresponding ratio, and the stirring mechanism blends the color mater batches to obtain the paint in demanded color. Compared with the prior art, the system achieves automatic blending of the color of the surface paint on the automobile awaiting paint repair, which overcomes the defects of poor efficiency and insufficient experience due to manual blending that depends on experience and greatly reduces the damage to human body due to volatilization of the paint.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Embodiment one:
A kind of automotive paints mixing color system, as shown in Figure 1, comprise frame 1, and the high-definition camera 2 connected successively, regulation and control center 3, ingredient sector 6 and rabbling mechanism 7, rabbling mechanism 7 is also connected with regulation and control center 3 simultaneously, and work under the control at regulation and control center 3, high-definition camera 2 gathers after touch-up paint surface of vehicle colouring information, the coarse adjustment look formula obtaining this color is analyzed by regulation and control center 3, and control ingredient sector 6 provides corresponding proportion to rabbling mechanism 7 paint look imperial mother according to the acquisition of coarse adjustment look formula, the paint obtaining required color is allocated by rabbling mechanism 7, deployed paint is collected by material fetching mechanism 9.High-definition camera 2, regulation and control center 3, ingredient sector 6 and rabbling mechanism 7 are all placed in frame 1.
Mixing system also comprises the sampling mechanism 8 be connected with rabbling mechanism 7, and with the feedback mechanism that is connected of regulation and control center 3, sampling mechanism 8 is also connected with regulation and control center 3 and works under the control at regulation and control center 3, sampling mechanism 8 obtains deployed paint sample in rabbling mechanism 7, and gathered the colouring information of this paint sample by feedback mechanism after, be sent to regulation and control center 3, regulation and control center 3, according to paint sample and after the color distortion between touch-up paint surface of vehicle, provides and compensates formula.Sampling mechanism and feedback mechanism are all placed in frame 1
Sampling mechanism 8 comprises the sampling plate of material identical with automobile case, the nozzle for sampling from rabbling mechanism 7, and for cleaning the cleaning unit of sampling plate, cleaning unit is all connected with sampling plate with nozzle, nozzle is also connected with rabbling mechanism 7, feedback mechanism comprises base light source 10 and sensor 5, base light source 10 is all connected with regulation and control center 3 with sensor 5, the paint sample of acquisition spreads upon after on sampling plate by nozzle, catch by sensor 5 light that paint sample sends under base light source 10 irradiates, and learn paint sample color according to the light caught.Sampling plate material identical with automobile case, can simulated automotive shell more truly, and then makes sampled result truer.
Ingredient sector 6 comprises the rough adjustment feature for performing coarse adjustment look formula and the trimming assembly for performing compensation formula, and rough adjustment feature is all connected with regulation and control center 3 with one end of trimming assembly, and the other end is all connected with rabbling mechanism 7.Rough adjustment feature and trimming assembly include multiple mixer being respectively used to deposit not homochromy mother, and be equipped with flow control valve between each mixer and rabbling mechanism 7, all flow control valves are all connected with regulation and control center 3.
Adopt the mode of image procossing and the complementation of color sensor feedback compensation link, modulated process is divided into coarse adjustment and fine setting two primary modulation processes.On the basis of image procossing, why introduce again base light source and color sensor as feedback compensation link, be for following some consider:
On the one hand, because image processing process is complicated, running time is longer.Particularly when comprising a large amount of pictorial informations in system library, this feature is more obvious.Herein, in the process of color of image identification, for improving the accuracy of Images Classification, SVM classifier is adopted to classify to image, and adopt the hybrid algorithm of Multilevel Iteration to optimize SVM parameter, although the generalization ability of SVM can be improved, the nicety of grading of grader is improved.But make the time needed for image procossing increase to some extent simultaneously.On the other hand, because each feature of image has important effect in the visual discrimination of people, any one feature of the single use color characteristic of single employing image (in the method) is carried out classification to image and always be there is error, therefore must calibration.Moreover, this applied environment towards final to as if human eye vision.Adopt the result of high-precision color sensor process can meet within human eye identifiable design accuracy rating completely, the similar human eye of this processing procedure obtains the process of image, makes modulation result more reliable.And reduce the spending causing system hardware resources because processing image in a large number.
Therefore, comprehensive above consideration, modulation accuracy and operational efficiency can be reached optimal effectiveness by the mode adopting image procossing and sensor feedback to compensate.
Mixing system also comprises host computer 12, this host computer 12 is connected with regulation and control center 3, receive and preserve the formula information sent by regulation and control center 3, communicated with communication unit 12 by communication unit 11 between host computer 12 and regulation and control center 3, wherein communication unit 11 is placed in frame 1, and communication unit 11 and communication unit 12 adopt the wireless mode work such as such as ZigBee technology.In addition mixing system also comprises touch display screen 4, and this touch display screen 4 is connected with regulation and control center 3, and receives the amount of paint of required allotment.
