Three-dimensional virtual dressing method of clothes for real person

The invention relates to a three-dimensional virtual dressing method of clothes for a real person, relating to the technical fields of digital clothing design. The system is characterized in that an object of the three-dimensional virtual dressing of the clothes is three-dimensional real-person body model structured according to the three-dimensional measuring data of the real person. A three-dimensional body measuring system measures the data of the real-person body of a consumer, the figure curve characteristic and the face characteristic, and guides the data into a three-dimensional dressing system; the original standard body model of the three-dimensional dressing system is corrected according to the data of the real person in the three-dimensional dressing system, and the three-dimensional real-person body model is showed virtually so as to lead the virtual body model to embody the figure characteristic and the face characteristic of the real person; the consumer and a designer decide the style, the fabric and the color design data by two-way selection, guide the data into a tailor-making system, complete the design of clothes and generate individual clothes sample pieces automatically; ready-made clothes are sewn virtually, and when the clothes are worn on the three-dimensional real-person body model, the individual dressing effect is intuitively displayed; and the design level and design efficiency of clothes are greatly improved.

Fast calibration method of active projection three dimensional measuring system based on two-dimension multi-color target

The invention discloses a projector and camera simultaneous fast calibration method used for an active projection illumination three dimensional appearance measuring system. The method utilizes a reasonable color design and utilizes the projector for projecting an image with multi-color characteristic points onto a two-dimension planar target with multi-color characteristic points on the basis of the RGB model of a multi-color image; a multi-color camera obtains two images after color blending in a color space of multi-color patterns on the target simultaneously at one time; information of a characteristic point image made on the target and information of a characteristic point image of projection are obtained by image separation; and then the method respectively utilizes the separated characteristic point image made on the target to calibrate the camera, utilizes the separated characteristic point image of projection to calibrate the projector and finally utilizes the principle of binocular stereovision to calibrate the relative position relationship of the camera and the projector, thus completing the calibration of the whole active illumination three dimensional appearance measuring system. As just one image is needed to be shot at each calibration position, the method has the advantages of less measuring data and fast calibration speed.

PVC (polyvinyl chloride) plastic building template

InactiveCN103665636AImprove flatnessNo significant increase in densityForming/stuttering elementsFiberProcedure Agents
The invention relates to a PVC (polyvinyl chloride) plastic building template which comprises raw materials as follows: PVC, foaming agents, foaming regulators, wetting agents, plasticizers, stabilizers, lubricating agents, anti-impact modifiers, processing auxiliaries, reinforced fiber, hollowed glass beads, hollowed ceramic micro powder, titanium dioxide, modified resin, filling agents and the like, wherein PVC can consist of a brand new PVC material and a PVC recovered material; and the modified resin can be at least one of PP (polypropylene) and PE (polyethylene) plastic particles. The hollowed ceramic micro powder with a small particle size and the hollowed glass beads with large particle sizes are mixed for use, the flatness of the surface of the building template is remarkably improved, the secondary plastering engineering is omitted, the demolding effect is good, the mounting is convenient, time and labor are saved, and the density of the building template is not remarkably increased; the heat absorptivity of the building template is reduced and the heat resistance of the building template is improved from the angle of color design; and even if the raw materials are doped with the PVC recovered material, a light-color building template even a white building template with less heat absorption can be manufactured.

High color saturation white light LED illumination system and mixed color design method thereof

The invention belongs to the semiconductor illumination technology field and particularly relates to a high color saturation white light LED illumination system and a mixed color design method thereof. Compared with routine LED illumination systems, on the condition of common color temperature (CCT) and common color rendering index (CRI), the mixed color white light LED illumination system has a higher gamut area index (GAI). A white light LED illumination object having high gamut area index is utilized, color saturation of an illuminated object can be substantially improved, color of the illuminated object is more brilliant, and preference and fondness of the illuminated object are improved for people. The high color saturation white light LED mixed color design method is for design of the white light LED illumination system, a color temperature adjustment scope 2000-10000K can be acquired, and the gamut area index (GAI) is greater than or equal to 100. Through the mixed color design method, a curve relation among red, green and blue (RGB) light proportions, a color rendering index and the gamut area index (GAI) is established, and thereby a new approach is provided for realization of high-quality intelligent illumination.

Color matching method for solving spot color printing ink in package printing

ActiveCN104476934AReduce manual color correctionSolve the problem that it is difficult to recruit ink color mastersOther printing apparatusSpecial data processing applicationsEngineeringPrinting ink
The invention discloses a color matching method for solving spot color printing ink in package printing. Different colors of printing ink samples produced by each printing ink factory are collected firstly, a common printing substrate is selected, and a reducer is added into the different colors of printing ink samples to dilute as the printing ink color paste. A printing ink proofer is used for displaying the sample of the color bar, the spot color ink matching software is used for controlling a spectral density instrument to collect the color density of the displayed color sample, and then the color density data is stored, the color density database is established. A computer is used for operating the spot color ink matching software to detect the tested color sample through cooperating with the spectral density instrument, the density data of the tested color sample is fed back to the spot color ink matching software, the spot color ink matching software is used for automatically calculating and screening the nearest tested color sample formula and formula proportion in the stored color density database, and then the formula and formula proportion are saved as the color sample formula file database by the computer. The method is capable of effectively improving the efficiency of ink matching, accurately matching, saving the printing ink, improving the production efficiency and the like.
