The two dimension printing of data on paper is converted into for from the picture number for being fed to computer by the improvement of printing technique According to the additive process of printing threedimensional model.The three-dimensional printer used at present is (such as one micro- every time by the way that printed material is layered Rice) build threedimensional model.The model created by 3 D-printing can include firm internal structure, and this is to traditional dies It is impossible.Structure can be carried out via 3 D-printing process using different materials (such as the plastics of different colours, metal or resin) Established model.Although can use a variety of colors and material for the usage of 3 D-printing, current three-dimensional printing technology is still It is limited to the model that major print surface shows simple reflex rate, such as lambert (Lambertian) surface, it can not be expressed just In the true reflex behavior for the practical object being modeled.

Although three-dimensional printer can be modeled to the detailed construction of Eiffel Tower, it can not catch in a model Obtain the real reflectance characteristic for the metal for forming actual Eiffel Tower.Reflectivity Characteristics can not correctly be captured by three-dimensional printer Labyrinth another example be people's (or other species) face.The face of live body includes the complex set of tints and shades And the complex way can not also be captured even with best high-resolution three-dimension (3D) printer carrys out reflected light.For example, mesh It is preceding it is available be resolution precision degree reach 16-30 microns three-dimensional printer.Therefore, when printing facial, such as hair and hair The feature in hole can be printed.However, the model printed even with the three-dimensional printer with optimum resolution Also appear to it is untrue, although it accurately replicates object structure.Because the reflective character of object by complexity because Element collection determines that these factors not only include the physical property (such as microcosmic surface details and color) of object, and including object The chemical property of itself.If without improvement set forth herein, 3D printing model can not capture exactly object how with light This details of interaction.

The multiple parasitic reflection for currently existing to capture and record in detail object (such as biological face or skin) is special The technology of property.The light stage that will be described in detail further below is an example.Similarly, also exist and set by calculating The technology of the standby reflection characteristic for producing object.For example, produced using the lighting engineering again based on image under any lighting condition The photorealism of object.The application of this technology, which is especially included in the scene of film, inserts character.

Using the device of such as dome-shaped light stage or portable lamp optical stage etc, for by irradiating from different directions Object captures the reflectivity data of object.The multiple images of object are captured, wherein the object in each image is come from and it His illumination of image different directions is bright.Therefore, the intensity of light of each pixel capture from all directions can be directed to, this can Rebuild pair by using mathematical modeling under any other lighting condition not captured by the device of such as light stage etc The image of elephant.This can be by being fitted to the albedo measurement obtained from the light stage for subject surface by Reflectivity Model Value is realized.In addition it is possible to use such as model of Lambertian, Phong or Ward model etc is calculated for specific One group of reflectance measurement that direction obtains, so as to obtain the intensity for the incidence angle being not included in measurement group.

The interaction of each surface and light can be described with bidirectional reflectance--distribution function (BRDF).Generally, light quilt The degree of reflection (or transmission) depends on observer and relative to surface normal and the optical position of tangent line.Because BRDF indicates light How to be reflected, it is therefore necessary to capture visual angle and the light pauper character of reflected light.Therefore, BRDF is at light interaction point Function of incident (light) direction with outgoing (visual angle) direction relative to local orientation.However, there presently does not exist assign 3D printing Model is with the technology of various reflective characters (such as those characteristics expressed by the BRDF of subject surface).

Embodiment disclosed herein can provide the model of object, and it has the reflective character of object, so that mould The type also reflected light in a manner of similar to object, thus appears more like reality compared with the model printed from conventional 3D printer Object.More specifically, embodiment described herein the light interaction property for being able to record object and these characteristics are applied to The model of object.This assigns model with the reflective character of object, so that model seems essentially identical with object.At one , can be by 3D printer printer model in embodiment so that the depth information of subject surface is trapped in 3D printer reception In data, model of the data transfer to printing.In one embodiment, the reflectivity data captured via retouching in detail herein The holographic technique that can be illuminated again stated is sent to 3D printing model.Depth and light interaction attribute two including practical object The 3D printing model of person will seem truer than the model obtained from 3D printer.

In certain embodiments, the reflectivity data of object weighs illuminated holograms quilt as be attached at 3D printing model Print.Holographic is a kind of illumination information for recording object and reproduces it in the case of no object afterwards So as to produce the technology for the illusion that object be present.In order to generate the hologram of object, with such as coherent source (such as laser) or light The light source of spectrum filtering light source etc carrys out irradiation object.Combined from the light of object reflection with reference beam, the reference beam can be Direct light from light source.The pattern as caused by the interference of the reflected beams and reference beam is trapped in the note of such as photo etc On recording medium.However, the recording figure forming captured by using holographic includes than the simple focusedimage of such as photo etc More information.This makes it possible to the 3-D view of reproduced objects, causes the illusion that object be present.

Fig. 1 is flow chart 100, and it illustrates the method for the model of the generation object according to some embodiments.This method from 102 start, wherein obtaining the model of object.In certain embodiments, object can be real object, such as, but not limited to people, Animal or other real worlds have life/abiotic object.In certain embodiments, object can be in real world Virtual/imaginary object that there may be or can be not present, it can include but is not limited to have life or abiotic entity.This A little virtual objects attribute (such as, but not limited to outward appearance, can include shape, size, color, texture, reflection characteristic and its His visible and invisible characteristic) it can be determined by their creator/designer.Subtraction as described herein or addition can be passed through Process obtains true or virtual objects models at 102.The image of object is input into 3D printer.Again, based on object It is real object or virtual objects, the image for being input to 3D printer can be that photo from camera or processor generate Image.By repeating to be layered to material (such as powdery resin), by 3D printer from the image received in additive process Generation model.Because 3D printer can be with the detailed construction of reproduced objects, it is possible to accurately represent object by 3D models The depth information on surface.In one embodiment, model includes coloured surface, and it includes red, green, blueness, cyan, yellow etc. In one or more.In one embodiment, model is made into identical with the size of object.

At 104, the illumination information of object is obtained.The illumination information obtained at 104 can not only represent to reflect, and Other complicated phenomenons occurred when light interacts with subject surface can be represented.This can include other phenomenons, such as but not It is limited to light absorbs and/or transmission, it includes but is not limited to diffraction and scattering effect.In one embodiment, the illumination letter at 104 Breath can obtain from the imaging device of such as light stage.In one embodiment, among other components, light stage also wraps Include camera and its intensity being capable of controlled light source.Light stage is arranged to produce gradient lighting pattern.Light source is configured With the surface for being arranged to use gradient lighting pattern irradiation object.The light reflected from illuminated subject surface is received by camera, phase Machine produces the data for representing reflected light.In certain embodiments, data can include the hologram for producing subject surface Interference figure.In certain embodiments, the data from camera are handled by computing system, to estimate the surface method of subject surface Line chart.

Polarizer can be by being placed on light source by the mirror-reflection normal map and diffusion normal map of subject surface respectively With camera in front of and produce, so as to using the sphere gradient lighting pattern of polarization come the surface of irradiation object.In one embodiment, Data from light stage can be used for estimating other attributes of subject surface.It is for instance possible to use for anti-by minute surface Penetrate the facial technology for reflecting to model of layering of rate, single scattering and shallow-layer and deep layer Subsurface Scattering composition.For these layers In each layer, the parameter of appropriate reflection model can be estimated using model as described above, for example, existing from single viewpoint Only 20 photos recorded in several seconds by light stage.

In one embodiment, the illumination information at 104 can be obtained from computing device.For example, it can utilize two-way anti- Penetrate rate distribution function (" BRDF ") and carry out modeled object surface outward appearance.As described herein, can be counted from using derived from analysis model Mathematic(al) function assesses the BRDF on surface.The reflectivity Characteristics of different kind of material can be determined using different models.It is actual On, measured BRDF databases can also be accessed from multiple sources.In one embodiment, can counted using path trace The light interaction property of subject surface is calculated in calculation machine with mathematical way.Path trace is that one kind is used for rendering three-dimensional scenes figure The computer graphical DSMC of picture.In fact, deposited in CG (computer graphical, computer graphics) is rendered The dispersion and scattering of even complicated light interaction property, such as sub-millimeter resolution (such as 1 pixel) are calculated in technology. Therefore, the illumination information in multiple regions of subject surface can be obtained by one or more physics or mathematical routine at 104.

For multiple regions of subject surface, illumination information is obtained at 104.In certain embodiments, for Object table Each region in face, illumination information can be collected at 104.Each area can be determined based on the expectation resolution ratio of obtained image The area in domain.It is expected that resolution ratio is bigger, the area in each region is with regard to smaller.Therefore, subject surface is divided into more in which can be supposed to Individual region is to obtain illumination information.

According to the method for obtaining illumination information, the illumination information for multiple subject areas obtained at 104 can To be encoded to multiple visual angles or multiple lighting conditions.For example, each pixel of digital hologram is the multiple of given light source Visual angle is encoded.Captured for the illumination information of this digital hologram by incremental camera motion, while by object Fixed position is maintained at light source.

In certain embodiments, for subject surface each region illumination information can to available for printing can again according to Multiple lighting conditions of bright hologram are encoded.This can be according to the embodiment being further detailed below by by camera Fixed position is maintained at object while changes the region clustering of light source and illumination information to realize.

At 106, the illumination information in each region of the subject surface obtained at 104 is printed as a series of holograms Out.Each hologram of the series includes the illumination information in one of the region of subject surface or it is encoded.Pass through Bright rather than limitation mode, each hologram of the series can include illumination information, such as one of region of subject surface Reflectivity data.Therefore, the reflectivity data in each region of the subject surface obtained at 104 is at 106 as holographic Figure prints.In one embodiment, the reflectivity data for each region of subject surface is represented by BRDF.Therefore, exist A series of holograms printed at 106 encode to the BRDF in each region of subject surface.Therefore, printed at 106 Hologram is configured to produce correct wavefront (wave front) so that hologram can expose all different to object Lighting condition is encoded.In one embodiment, including individual pieces of holograms a series of is printed at 106.Can be with A series of holograms are obtained using various known methods (such as those methods used by ZEBRA IMAGING).

In certain embodiments, this method moves directly to step 110, for identify 3D printing model and subject surface Each region corresponding to each several part so that appropriate illumination information can apply to 3D printing model.The table of the 3D models of printing Face can be divided into some with being supposed in a manner of similar to subject surface.By way of illustrating and noting limit, The quantity in the region of subject surface can be equal to the quantity of the imaginary part of 3D model surfaces.Therefore, each vacation of subject surface Think that region corresponds to the appropriate section of model surface.

Then, this method proceeds to step 112, for hologram sheet to be attached into model, therefore can save step 108. At 112, hologram sheet caused by 106 is attached to 3D printing model so that specific with model including subject surface Each hologram of the illumination data of a specific region corresponding to part is positioned and attaches to the specific part of model.Example Such as, hologram sheet can position and shrink wrapped is on model so that the spy of the illumination data of the specific region including subject surface Determine the appropriate section that hologram is attached to model.

In certain embodiments, this method is moved to step 108, is cut or draws including a series of piece of holograms It is divided into multiple fragments or multiple holographic small pieces.In one embodiment, piece is divided into so that each fragment or small pieces include printing A hologram in a series of holograms gone out.As the result of this separation, multiple printed holograms are obtained at 108, Wherein each printed holograms include the reflectivity data in one of the region of subject surface.Again, it is to be understood that in step The printed holograms of 108 generations or the quantity of holographic small pieces can be equal to the quantity or correspondingly equal to mould in subject surface region The quantity of type surface portion.By way of illustrating and noting limit, the area of the printed holograms obtained at 108 can be Extended between 0.000001 square millimeter to 0.25 square millimeter.In one embodiment, piece can be divided into so that a piece Include two or more holograms.It is understood, therefore, that multiple hologram sheets generated at 108 can include one Or multiple holograms, each hologram encode to the reflectivity data of the regional of subject surface.

In certain embodiments, this method is moved to 110 from step 108, wherein mark 3D models with subject surface Each several part corresponding to each region.The small pieces of the hologram sheet generated at 108 are attached to or are attached at the corresponding portion of model at 112 Point.Because 3D printing process is additive process, therefore 3D printer can be programmed, to be printed in the end layer of model When the small pieces of hologram sheet are attached to the corresponding parts of 3D models.For example, when building the appropriate section of 3D models, can be to 3D The mechanical ink-jet of printer is programmed to spray multiple small pieces of hologram sheet.
