Embodiment
The basic principle that the embodiment of the present invention is followed is that the light of light source prolongs straightline propagation, with three-dimensional body, shadow forms same straight line, so the formation of shadow is the linkage lines by light source and three-dimensional body to be projected a certain three-dimensional object surface and forms, if when our observation station and the position consistency of light source, we see that the outline of shadow must be also the same with the profile of three-dimensional body so.The present invention is specifically applied in survey field by this natural law just, by computer technology, simulate the relation of three-dimensional body and light source, and record the three-dimensional body projection with colouring information, in concrete place, predetermined viewpoint is replaced to light source position, three-dimensional body replaces as being projected object, record the final effect in three-dimensional scenic that is projected in forming, by obtaining projection, be printed on actual carrier surface, the image of printing is laid on both allocations in place, we are by the image after printing in the observation of predetermined viewpoint place like this, its effect just can be in full accord with observation three-dimensional body itself.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The invention provides a kind of manufacture method of projection of the three-dimensional body based on intended site, on this intended site, there is fixing mark, for example, one or more boundary line in place, one or more boundary points; Or, one or more regions of dividing in place, the boundary line in each region or boundary point; Or, the mark post with certain altitude on place or there is certain length, width and the building of height.This place can be construction site, stadium, all level grounds with certain area such as block.Described three-dimensional body can be the fixing building in place, or revocable thing of putting, and for example, three-dimensional text, stereo-picture, tridimensional advertisement etc. have the three-dimensional body of 3-D effect.
S101, according to the fixed signal in described place, simulate the three-dimensional scenic of described place under predetermined viewpoint;
Described three-dimensional scenic comprises the dimension of first in two-point perspective, the second dimension and the third dimension of tieing up the horizontal plane forming perpendicular to described the first dimension and second;
Correct three-dimensional perspective scene has determined that whether the projection of the virtual material object creating on its basis and the three-dimensional body finally obtaining is correct, in order to obtain a three-dimensional simulation scene consistent with actual place perspective relation, the embodiment of the present invention can be made by the following method, Fig. 1 be take football pitch as example, shows the manufacturing process of three-dimensional scenic.
A, under predetermined viewpoint, this actual place is taken, taken pictures or the video data that directly obtains this place obtains video interception or photo, above-mentioned video interception or photo are contained the main sign in place or complete main reference line substantially.Human eye is at different angular observation places and the marker in place, its shape and size are all different, above-mentioned said predetermined viewpoint, the position in the whole actual place of namely human eye observation, in embodiments of the present invention, can also be the position of video camera or camera.
B, then, the main sign lines in place in above-mentioned photo and video interception of take are benchmark, and the main reference line in place is carried out to refigure, if main reference line is imperfect, according to the angle of every reference line, its benefit is painted wholely, finally obtain the main reference line determined, referring to Fig. 2.According to those main reference lines, determine the three-dimensional perspective scene of above-mentioned place under predetermined viewpoint, this three-dimensional perspective scene comprises first peacekeeping the second dimension in two-point perspective, the namely length in the place based on level ground and wide angle, and the third dimension of the horizontal plane forming perpendicular to described the first dimension and the second dimension, namely perpendicular to the angle of the plumb line of level ground.
C, before producing three-dimensional perspective scene by video interception or photo or afterwards, can need according to the size of the main reference mark in fixed place and position, produce three-dimensional simulation scene, this three-dimensional simulation scene is not for a certain predetermined viewpoint, and viewpoint is random in other words.Can be according to size and the position of the sideline in place and/or important region line, by 3D, make the stereogram that software forms the elementary contour in this place, then according to the main reference line in the size of the main reference substance in this place, location positioning place, for example, if this place is divided, have a plurality of regions, some fixed reference thing, according to the angle of above-mentioned zone and reference substance and site boundary, distance, determines its position and angle in the stereogram of above-mentioned place.The size of this three-dimensional simulation scene and the size in actual place are on all four, are only the scene graph that chi dwindles in proportion.
D, then, by the three-dimensional perspective scene under the predetermined viewpoint obtaining in step B as a setting, the three-dimensional simulation scene creating according to place actual size in step C is placed on this background, the perspective relation of the three-dimensional perspective scene under predetermined viewpoint of take is benchmark, adjust the perspective relation of this three-dimensional simulation scene, make the main reference line of the three-dimensional simulation scene that creates according to actual size and the consistency that the three-dimensional perspective scene under predetermined viewpoint overlaps to reach perspective relation completely, thus the final three-dimensional scenic in the place under the predetermined viewpoint after being mated.
In above-mentioned two the three-dimensional scenic processes of coupling, can manually mate, also can make of computer adapting software, for example, 3D MAX software.If use computer adapting software, can be according to the main flag in place, preset a plurality of points, for example, the sideline intersection point in place, the intersection point in sideline, region, place, the outline line intersection point of key construction etc., choose at least 6 points and adjust perspective relation, the perspective relation of the more three-dimensional scenics of reference point and actual scene is just more identical, for example can choose 12 points of diverse location in place as the reference of perspective relation, make three-dimensional simulation scene consistent with the perspective relation of three-dimensional perspective scene under predetermined viewpoint.
S102, on described horizontal plane, create the virtual material object of the described three-dimensional body of simulation, the perspective relation of described virtual material object is unified mutually with the perspective relation of described three-dimensional scenic;
Created the three-dimensional scenic in place, just can have an X-rayed and in scene, create virtual material object and simulate the three-dimensional body in actual place at this, same virtual material object is placed in the three-dimensional scenic with different perspective relations, its shape is different, so must guarantee that this virtual material object is consistent with the perspective relation of this three-dimensional scenic, just can make it to reflect exactly the shape of the three-dimensional body in actual place.
Mode one:
For the perspective relation of virtual material object and three-dimensional scenic is consistent, can determine by power pin the shape of the virtual material object with preliminary dimension of a pre-position at three-dimensional scenic.The podium that Fig. 3 be take on football pitch is example, shows the process that creates the virtual material object of identical perspective relation according to power pin.
First need to determine the power pin in place, for example this three-dimensional scenic is mainly that width B and degree of depth A scope are wider, so there is no significant change because of span is little on height, so in this three-dimensional scenic, we generally follow the perspective fundamentum of two-point perspective (being two power pins of AB).
The fundamentum of two-point perspective is after we determine the width of what a scene and the power pin of the degree of depth, in drawing scene, in any new content, all need to make by the linkage lines of A depth perspective point and B width power pin, because there is no significant change on height, so the height in two-point perspective method is all vertical.
In Fig. 3, we can see that the sideline, region, place in scene is because the impact of perspective relation has produced certain modification, this modification is the result producing based on perspective relation, so the place line of the hierarchy structure that we can be by sideline, extended area finds power pin A and B, we have just determined two power pins like this.Then we just can take A and draw out the horizontal line of podium as linkage lines, and the B of take draws out the thickness of podium as linkage lines, highly all with straight line, draws.We remove unwanted reference line afterwards to treat to complete all the elements, have just obtained and the on all four virtual material object of whole three-dimensional scenic perspective relation.
Mode two:
If use Computerized three-dimensional software, for example, 3D MAX can directly add virtual material object in the three-dimensional scenic creating, and the virtual material object of interpolation meets the perspective relation in the three-dimensional scenic at its place.
First, according to actual conditions, determine the shape of the three-dimensional body in place, size, then, according to this size, create virtual material object, the virtual material object creating is moved to the set position in three-dimensional scenic, and Fig. 4 be take word ABC as example, shows the virtual material object directly adding in three-dimensional software.
After creating virtual material object, can below virtual material object, create one and be greater than the arbitrary shape of its scope and the horizontal plane of size.Can also on the horizontal plane below virtual material object, create a rectangle frame identical with the perspective relation of three-dimensional scenic, adjust the size of this frame, make it longly and wide just be slightly larger than or equal the outline of virtual material object on horizontal plane, that is to say, the size of this frame is just can wrap the minimum dimension of virtual outline in kind.Frame can help us to learn in advance the size of final print product.
Certainly, also can be in advance according to place situation, and the size in the projection of the three-dimensional body place that may take, on the horizontal plane of described three-dimensional scenic, create a rectangle frame with fixed dimension identical with the perspective relation of described three-dimensional scenic, then the virtual material object creating is moved in this frame, the size of adjusting the virtual material object creating, makes its outer contour on horizontal plane just touch the sideline of frame.
For example, if three-dimensional text can first create the word needing, then for font, add suitable thickness, font is moved to position set in three-dimensional scenic, then below font, create a horizontal plane that is greater than the arbitrary size of its font scope.Or, below font, create a frame that can just wrap above-mentioned word, word and horizontal plane (or word and frame) are amplified respectively and/or played up in three-dimensional software, form final two dimensional image, this two dimensional image is just as photo, be one and looked virtual an effect in kind, but be actually the image of a common plane.Virtual material object in this two dimensional image is with the specification of actual three-dimensional body and require unified mutually.Referring to Fig. 5, it is the manufacturing process schematic diagram of three-dimensional word ABC and frame; Referring to Fig. 6, be podium and frame manufacturing process schematic diagram.
When making virtual material object, also can first create plane material, then at three dimensions, create a virtual three-dimensional body with load plane material, the content that the shape of virtual three-dimensional body mainly need to show according to plane material is determined, if the content of plane material is a longer word, can use long carrying word virtual in kind; If the content of plane material is one, connect rotund object, just can first create a circular load plane material, add thickness then to this circle, and choose the face that need to add plane material, plane material is added to above circular object.Then below the virtual material object creating, create one and be greater than the horizontal plane of this three-dimensional body scope or above-mentioned frame, virtual material object and horizontal plane (or virtual material object and frame) are amplified and played up, form final two dimensional image, make it limpid in sight, meet the requirement of size and resolution.
S103, simulation are carried out projection from described predetermined viewpoint to described virtual material object;
After having created the virtual material object of identical perspective relation and play up in three-dimensional scenic, form final two dimensional image, then, just can in three-dimensional scenic, simulate at predetermined viewpoint place the virtual material object in this two dimensional image is carried out to projection.First, the horizontal plane that the first dimension of simulating ground, place in three-dimensional scenic in step S101 and the second dimension are formed imports in projection tools as projection plane, then by computer software, simulates at video camera or camera place virtual objects projection to projection plane.Fig. 7 shows the projection process of word ABC.Fig. 8 shows the projection process of podium.As can be seen from the figure,, at predetermined viewpoint video camera place, we see that perspective view is just as seen virtual material object itself.
Referring to Fig. 9 and Figure 10, left side camera is the video camera that presets good position, middle is the two dimensional image final effect of the virtual material object of having made after having played up, right side is projection plane for carrying the projected objects of final projection, the object of final carrying projection is a three-dimensional body, this three-dimensional body can be a rectangular planes in three-dimensional software according to actual needs, also can be the three-dimensional body of some other shapes, generally mainly use rectangular planes in three-dimensional software as projected objects, but in this example, be the more vivid feature that embodies projection, therefore use the spherical and three-dimensional cone of three-dimensional as the supporting body of projection.Gridiron pattern in Fig. 9 (being the two dimensional image final effect after virtual material object has been played up) is by the projection of camera position, projected three-dimensional sphere (the being projection plane) surface on right side, because the bending of spherome surface has produced the distortion of image, (projection plane is because of at an angle with virtual material object, so also can produce the distortion of effect same), this distortion sees it is an irregular deformation effect in other angles, but looks and be an image effect consistent with simulate effect in advance at predetermined camera position.
About projection tools, can make by choice for use ZBRUSH software, ZBRUSH is a digital engraving class software, we can utilize projecting function wherein to make projection.First the horizontal plane in the three-dimensional scenic creating in step S101 is imported in ZBRUSH as projection plane, then open the projection great master function in this software, the two dimensional image that includes virtual material object of making is added on this projection plane, after completing, again click the projection great master function in this software, the virtual material object in two dimensional image is projected on projection plane.
S104, the projection from obtaining described virtual material object directly over the described projection parallel with described horizontal plane.
After projection, directly over the virtual material object parallel with projection plane, obtain the projection of virtual material object.Then just obtained for the final image of printing, to be the final image of the projection of word ABC referring to Fig. 9; Figure 10 is the final image of the projection of podium.Finally need to will not have the part of picture material to cut, according to the actual size of reserve part, print and publish picture.
When making the virtual material object of the actual three-dimensional body of simulating in specific place, complex structure due to place, area is larger, and the camera distance of positions leave the theatre ground ground far, same three-dimensional body is placed on the diverse location of Same Site, even if differ 1 meter, in video camera seat in the plane, place sees that content difference is not very large, the shape that is to say the distortion of this virtual material object is distinguished also not obvious, but the projection difference of the virtual material object finally obtaining is very large, that is to say, in three-dimensional scenic, the angle of virtual material object and size are very large for the impact of the projection of the fluoroscopy images of final formation, often in measurement, very trickle deviation just can cause the direction that is projected in of the final three-dimensional body projection obtaining and actual three-dimensional body, the aspects such as angle differ greatly, this has brought a lot of obstructions to actual mapping and drawing, the embodiment of the present invention is by utilizing video interception or the photo at predetermined viewpoint place, determine the three-dimensional scenic in place, utilize perspective relation to determine the shape of the virtual material object in this scene and the shape of projection, and use computer to simulate accurately, the accuracy of the projection of shape of the virtual material object that can guarantee the three-dimensional scenic in this place and create in this three-dimensional scenic.
