Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
First, the invention provides a kind of 3-d photographs acquisition method, particular content is as follows：
1st, for subject, characteristic point is little in itself, such as the problem of the single smooth surface of color, can be using actively
Project the method for characteristic point to solve, wherein the light source for projecting there can be many selections.Here emphasis using array of rear-projectors come
Complete.Why array of rear-projectors is used, rather than a projecting apparatus, because a projecting apparatus 12 cannot often be irradiated to entirely
Subject, whole subject can be covered using array projector projects.Detailed process is implemented according to following steps：
Step 1, elder generation are shot for the first time by intelligent terminal array to static subject；Wherein, intelligent terminal battle array
The set of the composition of one or more intelligent terminal 11 is classified as, the intelligent terminal 11 is with access the Internet capability and takes
Carry the terminal of operating system.
Depending on the particular number and aligning method of the intelligent terminal array are according to specific requirement, line array is can be, but not limited to
Row, circular arc array or the space array that can be expressed by function.Here intelligent terminal 11 refers to possess access the Internet capability,
Various operating systems are generally carried, including but not limited to IOS, android system can customize various functions according to user's request
Terminal.
The software for operating in intelligent terminal 11 is photograph, video recording, recording or other data acquisition functions with customization
The characteristics of software, software is that parameter, preservation, lock function or some parameter groups that prestore for having customization supply next time as module
The function of integrally being recalled during using software, such as function of focusing, exposure or blank level adjustment.
Step 2, send first photographed data to image modeling server 13 again, obtain subject initial characteristicses density
Distribution Value, then best projection scheme is generated and transmission extremely projection according to initial characteristicses Density Distribution value by image modeling server 13
Instrument array；Wherein, the array of rear-projectors refers to the set for having one or more projecting apparatus 12 to constitute.
Depending on the particular number and aligning method of the array of rear-projectors are according to specific requirement, it is straight line that can be, but not limited to
The space array that array, circular arc array or certain function can be expressed.Projecting apparatus can be visible light projector, infrared light projection
Instrument or laser-projector.
Step 3, by each assigned optimal pattern of each synchronized projection of projecting apparatus 12 in array of rear-projectors, throwing
While penetrating optimal pattern, intelligent terminal array starts to shoot synchronous photo, to extract the region-wide characteristic point of subject.
First carried out once initially shooting the photo for obtaining by intelligent terminal array, feeding image modeling server 13 is processed
Afterwards, a subject initial characteristicses Density Distribution value is obtained.Generated most preferably by image modeling server 13 further according to this value
Projection scheme.This scheme refers to the different pattern of different projector projects, and this pattern can be certain structural light stripes,
Or certain structure light hot spot, it is projected the characteristic value that can increase subject on subject.Then by projecting apparatus battle array
The each assigned optimal pattern of row synchronized projection.And during this initially photographs optimal projection.Subject is needed
It is kept essentially stationary.While optimal pattern projection, intelligent terminal array starts to shoot synchronous photo, it is pointed out that
Specifically take pictures it is important that extracting the region-wide characteristic point of subject.But the subject texture for obtaining may with white light under
It is variant.If necessary to color texture under simulation white light, projection pattern can be closed, by intelligent terminal array retake once
Texture.
2nd, for subject different zones material and reflective attribute is inconsistent, causes the photo lithography time to be difficult to take into account
To the acquisition problems of the characteristic point of different zones, can using the method for multiexposure, multiple exposure, herein repeatedly for twice or more than twice.

(2) subject from intelligent terminal camera lens a little further.
(3) subject is shot using many focal length exposure methods by intelligent terminal array, many focal length exposures
Refer to that cannot be contained in many focal lengths taken within the depth of field of camera lens for subject repeatedly to be shot, obtain burnt section equal
The multiple pictures for differing.The method exposed using many focal lengths, herein be repeatedly exposure twice or more than twice, many focal lengths
Exposure refers to that the method that many focal lengths taken within the depth of field of camera lens repeatedly shoot cannot be contained in for subject.Every
The burnt section of photo is differed, and can thus allow computer program to be carried respectively from a series of photo in later stage three-dimensional reconstruction
Take out the characteristic point or characteristic parameter of the different burnt sections of subject correspondence.
The concrete scheme of many focal length exposures can be realized by one kind of following three kinds of schemes or any combination scheme：
(1) when intelligent terminal array is shot using an intelligent terminal 11, by the equipment of the intelligent terminal 11
Position is fixed, while the intelligent terminal 11 is shot to same subject respectively according to different Jiao is poly-；
(2) when intelligent terminal array is shot using an intelligent terminal 11, the equipment of the intelligent terminal 11 is pressed
It is poly- according to different positions and different Jiao, same subject is shot respectively；
(3) it is that each intelligent terminal 11 is set not when intelligent terminal array is shot using multiple intelligent terminals 11
With Jiao gather, then allow same subject shot.
Then can be the different focusing of different intelligent terminal reasonable arrangements using intelligent terminal array apparatus, so exist
Multiple photos that synchronization is collected just contain enough characteristic points of the different Jiao's sections of subject.But do so needs intelligence eventually
