Abstract
The invention discloses a non-feathered mapping curve model, relates to the field of computer graphics, and in particular relates to a model for making a nonlinear mapping relation by a feathering parameter and a splicing distance. The color value precision and the brightness adjustment of a projector are realized, and the vision effect of image displaying is enhanced. Pixel numbers are precise because components of red, green and blue (RGB) color signals are filtered, selected and separated; color values are automatically calculated according to signals acquired by a camera; and therefore, gamma curve correction is executed. Compared with the prior art, the non-feathered mapping curve model has the characteristics of unique concept, novel technology, precise pixel, precision color and simple method.
Description
Technical field
The present invention relates to field of Computer Graphics, in particular, is a kind of non-emergence mapping curve model.
Background technology
The input-output curve of projector is non-linear.Now a lot of manufacturers adopt artificial trial and error mode to determine that the edge merges a general emergence mapping, and it is should emergence mapping curve shape single, only adjust the curve width by adjusting inner parameter, the shape that does not have material change's curve, thereby real sprout wings value under each deformation state of the adjustment of meaning.And based on the emergence parameter that this principle generates, only can adjust the project of transverse horizontal splicing, for the correction of various irregular images such as special curved surface such as sphere, powerless.
Because the no regularity of deformation surface, then the color of different projectors, brightness adjustment are very difficult.Therefore the emergence coefficient calculations that merges band must be considered this nonlinear change rule of surf deform, through after this Nonlinear Mapping, produces bigger deviation with the brightness and the color-values of anticipation with the pixel value after avoiding sprouting wings.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of non-emergence mapping curve model, the color of solution projector, brightness adjustment problem, the visual effect that the raising image shows.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of non-emergence mapping curve model of the present invention, the emergence parameter forms nonlinear mapping relations with the splicing distance, pattern edge in selected scope, according to image splicing effect needs, the method to set up of the unique innovation of employing, the parameter that is about to sprout wings becomes the Nonlinear Mapping relation with the splicing distance setting, by mapping relations calculating accurately, get the most rational pixel value, reach image and show required design sketch.
A kind of non-emergence mapping curve model of the present invention adopts the RGB coding method, and every kind of color all can be used to be expressed as redness, green and blue intensity.Record and during color display to the processing that each component of RGB color signal filters, screens and separates, makes the color value of the more accurate match reality of color-values of each pixel, reaches the purpose of accurate correction.
A kind of non-emergence mapping curve model of the present invention, support is based on the auto color gamma curvature correction of camera, signal by camera collection calculates color-values automatically, has significantly reduced the interference of artificial subjective factor, has reached the precision target of proofreading and correct.
Compared with prior art, a kind of non-emergence mapping curve model of the present invention has thinking uniqueness, technology novelty, pixel is accurate, color is accurate, method is succinct characteristics.
Description of drawings
Fig. 1 is a modular structure exemplary plot of the present invention.
Embodiment
Below with reference to shown in the drawings and specific embodiments technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of non-emergence mapping curve model comprises and sets emergence parameter and the Nonlinear Mapping relation of splicing distance, comes to determine accurately the pixel value of image, reaches desirable pixel effects.
A kind of non-emergence mapping curve model comprises the processing to the RGB color signal, adopt the RGB coding method, to the processing that each component of RGB color signal filters, screens and separates, make the color value of the more accurate match reality of color-values of each pixel, easy and precisely errorless.
A kind of non-emergence mapping curve model, for auto color gamma curve, the signal by camera collection carries out curvature correction and calculates automatically, has significantly reduced the interference of artificial subjective factor, has reached the precision target of proofreading and correct.
The present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
