Description of drawings
Fig. 1 is the process flow diagram of three-dimensional panoramic model generation method in the embodiment of the invention.
Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.It should be noted that accompanying drawing of the present invention all adopts the form of simplification and all uses non-accurately ratio, only in order to convenient, the purpose of the aid illustration embodiment of the invention lucidly.
Please refer to Fig. 1, a kind of three-dimensional panoramic model generation method provided by the invention comprises:
Step 1: image modeling: the multi-angled shooting article also create the three-dimensional model of the article that are taken.
Particularly, described multi-angled shooting article step comprises:
Step 1A: prepare and build the shooting equipment.Wherein, take equipment and comprise: portable still life housing-case dress, namely the square portable sheen still life case of 40～80cm, photography lamp 4 overlap, and rotating disk is demarcated thing, camera and tripod.Build and take the equipment step and comprise: a), place the still life case; B), rotating disk is placed in the still life case between two parties; C), will demarcate thing smooth be put into center of turntable; D), the article (article) that will be taken are put into and demarcate the thing center position; E), open photography luminaire, regulate the lamp position, make light see through still life case uniform irradiation to the article that are taken.
Step 1B: the angle that camera is adjusted to the article that are taken is about 10～15 degree, rotates rotating disk and carries out a circle and take, and according to the article complexity, approximately takes 15～20 photos.
Step 1C: camera adjusted to be higher than article 45～60 degree that is taken, rotate rotating disk and clap one every 45 degree, take altogether 8 photos.
Step 1D: will demarcate thing and shift out, and take each one in article top and bottom of article photo, shooting is finished.
The three-dimensional model step that creates article comprises:
Step 1E: photo is scratched figure, particularly, utilizes software that the article in the photo are stingy from background, obtains the item pictures of blank background, further, can adopt photoshop software to carry out photo and scratch figure.
Step 1F goes back master mould, namely according to the shooting order item pictures is imported in the image modeling software, creates the three-dimensional model of article.Particularly, by the shooting order finished item pictures is imported in the image modeling software, use the many view geometry principles of computer vision, point, line in arbitrary image, image and obtain the Analytic Geometry and Algebra relation of the mutual alignment that obtains the space three-dimensional entity between the camera of image, generate point and converge, connect into certain dough sheet number, thereby the article in the image are carried out three-dimensional artificial, then by the texture of article in the image, obtain to have the three-dimensional model of real image.
Step 2: model is derived: import background picture, background music and action button in three-dimensional model after, again derive three-dimensional model.Particularly, at first three-dimensional model is derived from image modeling software, the file type of derivation is 3ds, a3d or dae file, imports in the virtual reality software again, and is rendered into picture.Then, in three-dimensional model, import background picture and background music; Then, add action button; Then, again derive three-dimensional model.Better, the three-dimensional model of derivation is the file of flash form.
Step 3: three-dimensional set panorama: make the spheroid panorama sketch and add interactive focus at the spheroid panorama sketch, focus is linked to the three-dimensional model of above-mentioned article, the issue three-dimensional panoramic model.
Particularly, make spheroid panorama sketch step and comprise: a, fish-eye camera will be housed be installed on the pan and tilt head, and be fixed on the tripod, and regulate the camera level, and take fish-eye optical centre as axle, revolving turns around take 4 fisheye photos; B, process Panoramic Mosaicing software splicing fisheye photo obtain the spheroid panorama sketch.Present embodiment adopts common PTGui Panoramic Mosaicing software.
Then, the spheroid panorama sketch of splicing is imported in the Panoramic Warping software, add that as required Panoramic Warping controls button and/or background music, and add interactive focus at the spheroid panorama sketch, focus is linked to three-dimensional model, the issue three-dimensional panoramic model, certainly, three-dimensional panoramic model also is the file of flash form.
The present invention has used up-to-date image modeling technolog, and by the 3 D stereo scene technology that real pictures is spliced into, and has that operation is simple, easy to operate, the characteristics of strong sense of reality.And the present invention well merges above-mentioned two kinds of technology exactly, has promoted user interaction and feeling of immersion, need not plug-in unit when web end network is showed, traditional needs are installed plug-in unit.In addition, implementing staff of the present invention only needs some technique for taking and some 3D basis, need not to be proficient in the 3D modeling technique, saves human cost.
