Summary of the invention

The present invention has overcome defectives such as existing stereoscopic photograph synthesis technique complexity, technical requirement height, cost of manufacture height, a kind of digital composing method of stereo picture is provided, and this method adopts digital form, the utilization Computer Processing, simplified operating procedure, increased work efficiency.

The present invention is achieved in that a kind of digital composing method of stereo picture, it is characterized in that this method comprises imports computing machine after multi-angle taken the multiple photos image digitazation obtain, through reconnaissance, computing, compression, apportion, close row, close figure and image and export and obtain stereo-picture;

(1) reconnaissance: on any width of cloth figure in photograph image, selected one is arranged in the mediate a certain unique point of level of sequence of stereoscopic images, is the benchmark alignment with all the other each width of cloth figure with this point, and divides cutting neat back deposit each width of cloth edge of image dislocation;

(2) computing: the grating pitch S that selected stereo-picture is adopted, the required width M of output stereo-picture calculates the required pixel number Q of photograph image width according to formula Q=M/S;

(3) compression: the photograph image width pixel after will cutting is compressed to the integral multiple Q ' of Q, i.e. photograph image width pixel compression multiple A=Q '/Q, and A is a positive integer;

(4) apportion: the pixel of every photos image is divided into the Q row, A pixel and arrangement in the following order that every row the time are got by compression: as photo P1:L11L12L13...L1Q, photo P2:L21L22L23...L2Q ... photo Pn:Ln1Ln2Ln3...LnQ;

(5) close row: the row of the respective column sequence number of each photos image are looked like to combine constitute new row combination L1:L11L21L31...Ln1, L2:L12L22L32...Ln2, L3:L13L23L33...Ln3 ... LQ:L1QL2QL3Q...LnQ;

(6) close figure: new row combination L1, L2, L3...LQ are arranged in order, be combined into the new stereo-picture of a width of cloth;

(7) image output: with the size that stereo-picture needs according to sheet, printout.

In the above-mentioned digital composing method of stereo picture, described photograph image width pixel compression multiple A is big, stereo-picture output accuracy height then, and the plain compression multiple A of general capture is 1.

Principle of work of the present invention is to adopt digitizing technique and computer technology, at first with the photo digitizing of taking, will be with traditional camera or the captured photo of stereocamera, convert the photo analog image to digital picture, or adopt digital camera or 3-D digital camera to take, directly obtain digital picture; Then digital picture is carried out digitized processing, thereby comprise digital picture is carried out reconnaissance, computing, compression, apportion, closes row, closed behind the figure image output is obtained stereotome; With stereotome aim at cylindrical grating and bonding after, promptly become the stereoscopic photograph works that a width of cloth has stereo displaying effect.This method has realized that stereopsis handles digitizing, robotization and high efficiency, thereby significantly reduces working hour, raises the efficiency and reduces cost.

Description of drawings

Fig. 1 is the process flow diagram of digital composing method of stereo picture of the present invention, and Fig. 2 is a photograph image apportion synoptic diagram, and Fig. 3 lists intention for photograph image closes, and Fig. 4 forms the stereo-picture synoptic diagram for photograph image closes the row back, and Fig. 5 is the digital composition principle figure of stereoscopic photograph.

Embodiment

Referring to Fig. 5, at first be that subject is taken, obtain photograph image, the comparison film image carries out obtaining digital picture and importing computing machine after the digitized processing.After can adopting the stereocamera of traditional camera, the decorum that subject is taken, photograph image is carried out digitized processing, as adopt scanner to convert analog image to digital picture, or after directly adopting digital camera to take, obtain the digital photo image.The comparison film image carries out digitized processing then, referring to Fig. 1, through reconnaissance, computing, compression, apportion, close row, close the output of figure and image and obtain stereo-picture, with stereo-picture aim at cylindrical grating with bonding after, promptly become the stereoscopic photograph that a width of cloth has appreciation effect.

Digital composing method of stereo picture is:

(1) reconnaissance: on any width of cloth figure in photograph image, selected one is arranged in the mediate a certain unique point of level of sequence of stereoscopic images, as on the object of the outstanding behaviours of wanting in the human eye in the personage photography, the still life photography certain a bit, is the benchmark alignment with all the other each width of cloth figure with this point, and divides cutting neat back deposit each width of cloth edge of image dislocation;
