Description

Method for fastly producing three dimension figure

The invention belongs to three-dimensional modelling field in kind, relate generally to a kind of process that can make three-dimensional portrait according to client's figure and features morphological feature.

The making of 3 D stereo portrait generally comprises the making that wooden statue, gypsum statue, cast copper metallic statue, waxen imagen, glass decorations look like etc., long owing to complex process, fabrication cycle, producer's professional standards are required reasons such as height and cost of manufacture be high, always be to belong to " the franchise manor " that some great men or celebrity are enjoyed, and general ordinary people rarely have and make inquiries.In recent years, along with the progress of society and the raising day by day of common people's culture mastery and quality, a kind of new industry of three-dimensional small-sized effigy of the available handwork sculptures towards general public has just been risen in some countries and regions, by this small-sized three-dimensional model portrait, people just can from different angles go to appreciate objectively own or other people be close to three-dimensional looks and form true to nature, but not only cost is higher for the portrait of sculpture by hand, the more important thing is and limit by working condition, can not be produced in batches (industrialization can't be reproduced), so also be difficult to satisfy the requirement of people's different levels.

The objective of the invention is to utilize modern science and technology particularly computer technology in the application technology in fields such as portrait production and machining, exploitation is also designed a kind of higher cost, simple and reliable method for fastly producing three dimension figure and corollary equipment thereof of need not, by development and enforcement to this method and apparatus, the user can copy its 3 D stereo portrait according to the figure and features morphological feature of making as client fast realistically in the relatively shorter time, satisfy the demand that general public wishes to have own three-dimensional portrait largely.

As the technical solution that realizes above goal of the invention, rapid-result method of making three-dimensional portrait of the present invention mainly comprises following technical process: 1. by the three-dimensional portrait production of a cover equipment client is done many side-specific of ring body curve and make a video recording continuously; 2. the image information of gained of will making a video recording is sent into computer processing system, after " special electronic three-dimensional imaging software " routine processes, is converted into numerical control information; 3. through processing cerul mould material base or rosin basic mode material base, make it to become the necessary finish cast die type of smart casting with the Digit Control Machine Tool of computer interconnection use; 4. carry out casting of molten mould essence and foundry goods refine according to the finish cast die type, produce the 3 D stereo statue of also approving that meets client's figure and features feature through technologies such as surface treatments at last for client.Technology of the present invention also is useful in other the three-dimensional simulation making technical field in kind except that portraiture.

To make in conjunction with accompanying drawing behind the literary composition further specifying of the method for the invention and corollary equipment.

Accompanying drawing 1 is the process chart of three-dimensional portrait preparation method.

Accompanying drawing 2 is produced the work schematic diagram of on-the-spot corollary equipment for three-dimensional portrait.

With reference to accompanying drawing 1, when making a secondary 3 D stereo portrait, at first to do ring body (or ring head) shooting continuously, with the figure and features information (in the ring body shooting, preferably adding front and the side photo of clapping several these clients again) of the specific curves that obtains this client's all directions side to client.Shooting technical process of the present invention is by a video camera with computer interconnection the ring body that client does the side-specific curve to be made a video recording continuously.After shooting is finished; the image information of shooting gained is sent into computer processing system; after " electronic three-dimensional imaging software " (this software has been applied for protection of computer copyright and corresponding protection of the patent right) routine processes of inventor's development, be converted into numerical control information.During enforcement, can be according to client's specific requirement, produce or be treated to personnel's full-length picture, bust and talking head respectively as three kinds of numerical control information, and then by Digit Control Machine Tool processing mould material base, so-called mould material base be exactly with essence cast required cerul mould material or rosin basic mode material according to people's various figures unified produce several leave the blank of processing capacity, the mould material base portrait that processes through specialized nc machine tool, face and form are the spitting image of client." refine mould material base " operation is to allow the skilled worker of certain technical ability experience according to photo or other recent photograph that client takes synchronously, and manufactured mould material is further processed aspect the romantic charm, revises the defective of some quality aspects in the mould material base simultaneously." smart casting of molten mould " after " refine mould material base " technology and operations such as " foundry goods refine " are the mature technologies during modern industry is produced, in this outline, after this two procedures is finished, again to model polish, surface treatment such as sandblast, colouring, plating, assembled at last and operation such as packing, formed final products.

The three-dimensional portrait product of producing according to above-mentioned three-dimensional portrait preparation method is branch record portrait product and assembling portrait product two big classes mainly.What record portrait product reflected is that client is in on-the-spot looks form and the clothing situation at that time of being made a video recording; And the making of assembling portrait product, earlier produce client's head dummy picture often according to client's appearance, and then this head dummy looked like to be assembled on some standard body models, on body model's model and some famous sculptures (Venus, David, thinker, mermaid, cherub etc.) model, to obtain good art and to appreciate effect.

Realize that the three-dimensional portrait production equipment (as shown in Figure 2) that technical solution of the present invention adopted is different from common photo studio, it is the equipment that a kind of video camera can be made each angle faces sequence photography of ring body around the client side.During concrete enforcement, this equipment can have two kinds of basic forms of the composition, first video camera is motionless, and by the form of the relative video camera rotation of production person, it has relatively 360 ° of rotary seat stands 2 that the angle constant speed is rotated of video camera 5 works of a fixed cameras 5 that connects with computer 7 inputs and, the special light source 1 that is used to throw light on is located at the positive side limit of stand 2, its axial plane all the time with 5 one-tenth 45～90 ° of angles of video camera, the top that is positioned at system object being shot on the central axis of seat stand 2 is provided with a cylindricality adjuster 8, and we are called A type production form this production form; Two to be produced object motionless for it, and video camera is done around the form of taking around human body, it has a fixing seat stand 2 and the rotation camera-shooting table that can do 360 ° of angle constant speed rotations around the seat stand, on camera-shooting table, put a video camera 5 that connects with computer 7 inputs is arranged, the special light source 1 that is used to throw light on is located at the transition of rotation camera-shooting table, its axial plane all the time with 5 one-tenth 45～90 ° of angles of video camera, the top that is positioned at system object being shot on the central axis of seat stand 2 is provided with a cylindricality adjuster 8, and we are called Type B production form (also can do the multiple cameras setting that equal angles distributes around seat stand 2 between shooting certainly) this production form.The special light supply apparatus 1 that adopts in the said equipment is a kind of band light source device that sends vertical banded light face.Label 3 is the human body fixed band among Fig. 2; Label 4 is the peripheral set extinction background of seat stand; Label 6 is for doubting the viewpoint light supply apparatus.

The process that adopts A type production mode to make a video recording is such: make client be sitting in or stand on the rotary seat stand 2, and it is (stronger as client's self-control certainly with fixed band 3 stable firmly its healths, also can be without fixed band 3), the staff installs column adjuster 8 at client's apical head; After everything is ready, close other on-the-spot light source of shooting, only stay banded light face and doubtful viewpoint light source 6 and instrument panel lamp etc. that band light source device 1 sends, because floor is very dark, has only a branch of stronger banded light from the side according to the subject (see figure 2), so form an eye-catching curve; At this moment the cameraman opens video camera 5, and synchronous initiation rotary seat stand 2 at the uniform velocity rotates a circle or certain angle human body, and in rotation, video camera is made continuous shooting to the specific curves of each side of subject.Because floor is very dark, extinction background 4 no-reflections around the equipment, so video camera 5 is taken in camera lenses only is that band light source device 1 is radiated on the human body and an endways very narrow very bright curve that forms, it is the closed curve of plane ring-type by crosscut that the information via electronic computer 7 of these curves and supporting " electronic three-dimensional imaging software " system handles become some, is converted into numerical control information at last soon.

The process and the above-mentioned A type production mode that adopt Type B production mode to make a video recording are basic identical, and just the rotation mode of rotating mechanism is distinguished to some extent, does not do at this and gives unnecessary details.
