Summary of the invention:
The technical matters that the present invention will solve provides a kind of synthetic method that is used for the stereo-picture of rectilinear orbit photographic images.
Technical solution of the present invention is, a kind of synthetic method of stereo-picture is provided, and described synthetic method is based on that image that line slideway takes and computer software realize, may further comprise the steps:
(1), the original image that import to adopt rectilinear orbit to take, according to the time order and function rank order of taking, and calculate number;
(2), all pictures are overlapping successively, let certain of the same information of expression in the picture a bit overlap;
(3), be pivot center with the vertical curve at above-mentioned coincide point place, and be reference frame with first pictures, rotates second to a last pictures, make that angulation is equal between every adjacent two pictures, obtain one group of sequence chart;
(4), according to the grid stroke number of setting, calculate and arrange each sequence chart on the line preface of correspondence, generate finished figure.
Adopt after the above method compared with prior art; The present invention has the following advantages: the inventive method is to be used for the processing of rectilinear orbit pictures taken and synthetic, and finally forms stereo-picture, through adjusting every original image stack back angulation; With changing in the post-processed of picture through the arc track shooting in the prior art; Avoided the deficiency that arc track brought, made to adopt the rectilinear orbit shooting and handle the formation stereo-picture to become possibility, in addition; Can also adjust the displacement interval of every photo, speed is inhomogeneous when revising orbital motion.
As improvement, in the step (3), obtain one group of sequence chart after, regulate sequence chart, make this group sequence chart be in same horizontal level.Because when taking, track is taken and is had certain error, causes the photo of shooting not exclusively to be on the same horizontal level, sequence chart adjusting level has been improved the synthetic quality and the appreciation effect of picture.
As improvement, in the step (3), calculate the best number of confirming required sequence chart according to the desired resolution of final composite diagram, and in sequence chart, screen.According to resolution, confirm optimal sequence figure number, can improve the quality of composite diagram, satisfy user's demand.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
The synthetic method of stereo-picture of the present invention, described synthetic method are based on that image that line slideway takes and computer software realize, may further comprise the steps:
(1), the original image that import to adopt rectilinear orbit to take, according to the time order and function rank order of taking, and calculate number; Described rectilinear orbit shooting is meant through camera at the uniform velocity mobile on rectilinear orbit, and takes the original image that obtains different shooting angles continuously.
(2), all pictures are overlapping successively, let certain of the same information of expression in the picture a bit overlap; A stereo-picture generally all carries many information of taking original image, and certain some coincidence with the same information of expression in the picture in this step is further to confirm pivot center for step 3.
(3), be pivot center with the vertical curve at above-mentioned coincide point place, and be reference frame with first pictures, rotates second to a last pictures, make that angulation is equal between every adjacent two pictures, obtain one group of sequence chart; Owing to adopt arc-shaped guide rail need not adjust angulation between the picture, this step has remedied the deficiency that line slideway is taken.
(4), according to the grid stroke number of setting, calculate and arrange each sequence chart on the line preface of correspondence, generate finished figure; Described grid stroke number is to generate the line number that finished figure covers grating used on the finished figure afterwards; After covering specific grating on the finished figure; No matter people can both see two different sequences figure from which angle, that is to say no matter see from which angle all can produce stereoscopic sensation.
In the step (3), obtain one group of sequence chart after, regulate sequence chart, make this group sequence chart be in same horizontal level.Because when taking, track is taken and is had certain error, causes the photo of shooting not exclusively to be on the same horizontal level, sequence chart adjusting level has been improved the synthetic quality and the appreciation effect of picture; Can also regulate the angle of inclination of every photo, adjustment is vertical, and described adjustment vertically is to cause in order to eliminate the incomplete level of rectilinear orbit to tilt to take.
