Description

Customize the method for three-dimensional statue with three-dimensional camera
Technical field:
The present invention relates to a kind of bat access method about three dimensional object, especially relates to a kind of bat and gets the two and three dimensions image and two-dimensional image information is customized technical method on three dimensional object.
Background technology
[0001] the general bat with traditional two-dimensional numerals camera of the image of people or other three dimensional object got.Recently, digital camera is used to clap the two dimensional image of getting three dimensional object.The stored digital of these digital images makes impression sense rich details and color to be clapped by digital camera and get, and is printed then or viewed.
[0002] Figure 1A-B shows is to get the digital camera of two dimensional image and in order to show the computing machine and the printer of two dimensional image in order to bat.Digital camera 12 has a camera lens among Figure 1A, and this camera lens is used to clap fetches the light that comes from object 10.After being collected, the light that derives from object 10 is sent on the charge-coupled device (CCD) or other image inductor in the digital camera.The light with obtaining of two-dimensional surface charge-coupled device (CCD) converts different x on the two-dimensional surface of representing charge-coupled device (CCD) to, the pixel of color on the y bitmap and shade degree.
[0003] pixel of digital camera 12 generations is stored in the form of standard, such as JPEG (joint photographic experts group) form (JPEG) or bitmap format (BMP).These pixels may show as certain form, for example Bel (Bayer) form.At this some x, have the pixel of some color on the y position, but lack the pixel of other color.Therefore, need insertion to generate default color.
[0004] among Figure 1B, personal computer PC 14 receives the jpeg image text from the digital camera 12 of Figure 1A.The storage card of digital camera 12 is inserted into 14 1 special readers of personal computer PC, and perhaps a kind of interface such as the USB line, is used to the transmission of digital image file to personal computer PC 14.The digital picture that shows with jpeg format literary composition file may be converted into pixel and be shown in computer PC 14, perhaps is converted into printable pixel and prints by printer 16.Printer 16 can be exported the two dimensional image 18 of three dimensional object 10.Although color and detailed information are arranged, two dimensional image 18 is still plane picture, thereby image has been owing to lacked the third dimension, and it also is not that the perfection of three dimensional object 10 substitutes picture.
[0005] Fig. 2 A-B shows in order to generate three-dimensional reproduction a kind of three-dimensional camera and a kind of three-dimensional polishing (finishing impression) machine originally.Among Fig. 2 A, three-dimensional camera 20 is clapped the 3-D view of getting three dimensional object 10.Three-dimensional phase function uses multiple technologies not only to comprise two dimensional image in order to obtain, and also comprises the three-dimensional information of object 10.For example, some three-dimensional camera may be equipped with the mechanical probe on actual contact three dimensional object 10 surfaces.When mechanical probe when three dimensional object 10 slips over, three-dimensional camera 20 is clapped the movement locus of getting probe, this movement locus is corresponding to the three-dimensional feature of object 10.
[0006] other technology of three-dimensional camera 20 may use laser range finder to measure the distance between three-dimensional camera 20 and the three dimensional object 10 outer table position.This stadimeter can be along three dimensional object 10 across scanning.Another kind method is to throw the coordinate net ruling to three dimensional object 10 surfaces, is looked like to be presented on three dimensional object 10 surfaces by the distortion on the projection grid then, is clapped by three-dimensional camera 20 and gets.The coordinate net ruling has the identification of the auxiliary profile of different colors.A kind of is that the sinusoidal curve of time variability also can be projected onto three dimensional object 10 surfaces, and three-dimensional camera obtains different variations constantly.Another three-dimensional camera 20` may be used for clapping to get to be rich in relief image, and perhaps moving three dimension camera 20 is found a view from different sides or angle, is combined into the three-dimensional model of single object 10 then.
[0007] three-dimensional information can be stored as the profile diagram of Z or be additional to the range data that camera is clapped the ordinary two-dimensional image information of getting.The three-dimensional geometry text formatting of some standard with such as DXF the form of VRML and STL exist.Also can use different proprietary formats.
[0008] among the image 2B, a kind of three-dimensional sander reads geometric text from three-dimensional camera, and the three-dimensional profile of getting object is clapped in polishing.Different rapid prototyping systems can utilize.Such as computer digital control (CNC) sander.Sander 24 is received the geometric text that three-dimensional camera 20 obtains, and the conversion geometric text is the motion of a series of drilling machine or lathe drill bit 22.Sanding block 28 loads on sander 24, and can move up and down and overturn by tipper, to allow the drill bit 22 position cutting desirable on the sanding block surface.After after a while, drill bit 22 has excised the part of sanding block 28, has showed profile 26 after the desirable polishing.Profile 26 after the polishing is to clap the alternative picture of getting and be converted to the three dimensional object 10 after geometric text sends to sander 24 through three-dimensional camera 20.
[0009] although the profile 26 after the polishing is alternative pictures of three-dimensional of three dimensional object 10, it may lack color, texture and the other parts feature of three dimensional object 10.For example, sanding block 28 may be wax stone or plastics, may be a kind of color harmony texture.Polishing back profile 26 has only a kind of color harmony texture like this, and different color harmony texture is arranged unlike three dimensional object 10.
[0010] (Figure 1B) in the three-dimensional information process that loads the profile 26 of having polished, the color of two dimensional image 18 and texture detailed information have lacked.Yet two dimensional image 18 lacks the degree of depth and the shape of the profile 26 of polishing.Profile 26 did not all copy color, detailed information and the profile of three dimensional object 10 satisfactorily after two dimensional image 18 was still polished.
What [0011] Fig. 3 showed is a kind of in order to customize the classic method of three-dimensional statue.After the image of object 30 was got by bat, image printed with color printer 33 or is printed off by photo store; On the basis of two dimensional image 34, the sculptor carves face and head 35 with the cement material.
[0012] the polished soft viscosity object 35 of moulding need carry out cure process, for example is put into kiln or baking oven sclerosis viscosity head portrait 36; Another kind of sclerosis viscosity object 36 is that double teeming is other resinousness material that can harden rapidly.The tame application image 34 of painting sprays and hardens but still uncoloured head portrait 36, makes it similar to image 34, becomes the head portrait 38 of a complete painted sclerosis.
[0013] air brushing painted after, the head portrait 38 of fully painted sclerosis installed or mounting spring not, be installed to then and form a complete statue 39 on the health statue.
[0014] yet, clap in the image basis of getting with general camera 12, be not easy to allow the sculptor control the similarity of each honor object, facial each appearance size, the position is consistent and each quality that carves out.
[0015] ideal results is each appearance size more true to nature, facial, and the position is consistent, colorful three-dimensional statue.Therefore, extract each concrete details information of three peacekeeping two dimensions, utilize these information to generate the object duplicate of a 3D shape, this will be to be solved by this invention.
Invention description
[0010] the relevant improvement technology of making the three-dimensional statue of customization of present technique.Following explanation is intended to allow those of ordinary skill in the art and use this invention according to the regulation utilization of applying for literary composition and essential features.For the people of all this art of understanding, it is tacit at that time to obtain optimum efficiency to make corresponding modification at concrete object.Hereinafter the rule that is defined is equally applicable among other embodiment.So, shown in the present invention is not limited to and the specific embodiment of explanation, meet the principle that hereinafter discloses and the maximum magnitude of novel features but cover.
[0011] Fig. 4 shows be take about strengthening three-dimensional/two dimension, three-dimensional polishing and two dimension is printed, it is painted to carve, spray on the basis of three-dimensional polishing and head portrait is installed to synoptic diagram on the health statue.Three-dimensional camera 41 can utilize laser ranging or other technology to take three dimensional object 40 geometric detail information.These geometric detail information are adorned is geometric text 42, shows as such as standard formats such as DXF, STL, VRML, IGES.Geometric text 42 comprise relevant three dimensional object 40 surface points (z, y, z) data, the data of different points is inequality.
[0012] at the X that takes how much documents 42 with three-dimensional camera 41, Y, in the time of the Z data, a two dimensional image also is taken.It is desirable to, this two dimensional image is that this has at utmost been avoided distortion with the lens shooting of the three-dimensional camera 41 of taking three-dimensional data.Executing at some can be a little by the payment laser range finder with the lens shooting image in the example.Two-dimensional image data is loaded jpeg image text 43.Image text 43 also may adopt other form, as TITF.Record is presented at three-dimensional camera 41 plane pictures, and (x, y) the colored pixels data of position are included in the two dimensional image text 43.
[0013] so, three-dimensional camera 41 output geometric text and two dimensional image texts 43.The three-dimensional camera that sell some commercial channel just can be exported text 42 and two dimensional image text 43.Such as VIVID700 three-dimensional camera with your tower (Minolta) of minot.
[0014] geometric text 42 is defeated by three-dimensional sander 44, sander 44 may be the computer numerical control machine, such as computer-controlled lathe, sander, drilling machine etc.Geometric text 42 may be handled at first, and conversion generates the machine instruction on the sander 44.Sanding block 45 is loaded on the sander 44, is polished into customization polishing profile 46, this polishing profile 46 is possessed the profile of the three dimensional object 40 of geometric text 42 explanations.
[0015] two dimensional image text 43 is transported to microcomputer PC47.Microcomputer PC47 generates the print text of two dimensional image, and print text is transported to printer 48.
