Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
One, the invention provides a kind of 3-d photographs acquisition method, particular content is as follows:
1, little for the characteristic point of subject own, the problem of the smooth surface that such as color is single, the way actively projecting characteristic point can be adopted to solve, the light source wherein projected can have a lot of selection.Here emphasis adopts array of rear-projectors to complete.Why adopt array of rear-projectors rather than a projector, because a projector 12 often cannot be irradiated to whole subject, adopt array projector projects can cover whole subject.Detailed process is implemented according to following steps:
Static subject is shot for the first time by step 1, elder generation by intelligent terminal's array；Wherein, this intelligent terminal's array is the set that one or more intelligent terminal 11 is constituted, and this intelligent terminal 11 has access the Internet capability and carry the terminal of operating system.
Particular number and the aligning method of this intelligent terminal's array are determined according to specific requirement, it is possible to but it is not limited to linear array, circular arc array or the space array can expressed by function.Here intelligent terminal 11 refers to and has access the Internet capability, generally carries various operating systems, includes but not limited to IOS, android system, can customize the terminal of various function according to user's request.
The software operating in intelligent terminal 11 is the software with the photograph of customization, video recording, recording or other data acquisition functions, the function that when feature of this software is to have the parameter of customization, preservation, lock function or some parameter group that prestores as module for software next time, entirety recalls, for instance the function of focusing, exposure or blank level adjustment.
Step 2, send first photographed data to image modeling server 13 again, obtain subject initial characteristics Density Distribution value, then generated best projection scheme transmission to array of rear-projectors by image modeling server 13 according to initial characteristics Density Distribution value；Wherein, described array of rear-projectors refers to the set that one or more projector 12 is constituted.
Particular number and the aligning method of described array of rear-projectors are determined according to specific requirement, it is possible to but it is not limited to the space array that linear array, circular arc array or certain function can be expressed.Projector can be visible light projector, infrared light projection instrument or laser-projector.
Step 3, by each assigned best pattern of each projector 12 synchronized projection in array of rear-projectors, while the best pattern of projection, intelligent terminal's array starts shooting and synchronizes photo, to extract the region-wide characteristic point of subject.
First undertaken once initially shooting the photo obtained by intelligent terminal's array, after sending into image modeling server 13 process, obtain a subject initial characteristics Density Distribution value.Best projection scheme is generated by image modeling server 13 further according to this value.This scheme refers to the pattern that different projector projects is different, and this pattern can be certain structural light stripes, or certain structured light hot spot, and it is projected the eigenvalue that can increase subject on subject.Then by the best pattern that array of rear-projectors synchronized projection is each assigned.And this initially photographs in the process of best projection.Subject needs to be kept essentially stationary.While best pattern projection, intelligent terminal's array starts shooting and synchronizes photo, it is pointed out that take pictures specifically it is important that extract the region-wide characteristic point of subject.But it is variant that the subject texture obtained is likely to under white light.If needing color texture under simulation white light, it is possible to close projection pattern, by texture of intelligent terminal's array retake.
2, inconsistent for the material of subject zones of different and reflective attribute, cause that the photo lithography time is difficult to take into account the acquisition problems of the characteristic point of zones of different, the method that multiexposure, multiple exposure can be adopted, herein be repeatedly twice or more than twice.Multiexposure, multiple exposure refers to and first exposes one by light value for same subject, then increase on its basis and reduce light exposure and respectively expose one, if still without holding, the many bats of light exposure several can be changed more, light exposure can be regulated for 1/3EV, 0.5EV, 1EV etc. by differential, the light exposure of every photo all differs, and thus computer program can be allowed to extract enough characteristic points or characteristic parameter that subject zones of different comprises owing to material is different with reflective attribute from a series of photo respectively when later stage three-dimensional reconstruction.
The concrete scheme of multiexposure, multiple exposure can be realized by the one of following three kinds of schemes or combination in any scheme:
(1) when intelligent terminal's array adopts an intelligent terminal 11 to shoot, the position of described intelligent terminal 11 equipment is fixed, same subject is shot according to different exposure parameters by described intelligent terminal 11 respectively simultaneously,
(2) when intelligent terminal's array adopts an intelligent terminal 11 to shoot, by described intelligent terminal 11 equipment according to different positions and different exposure parameters, respectively same subject is shot.
(3) when intelligent terminal's array adopts multiple intelligent terminal 11 to shoot, different exposure parameters is set for each intelligent terminal 11, same subject is shot simultaneously.
Adopt intelligent terminal's array apparatus, the then exposure parameter that the equipment reasonable arrangement that can be different is different, so just contain enough characteristic points of subject unlike material and retroreflective regions at the photo that synchronizes that synchronization collects.But do so needs intelligent terminal's array closeness high, and advantage is that by instantaneous taking pictures.If intelligent terminal's array closeness is relatively low, then each equipment multiexposure, multiple exposure can be adopted to realize.But the static degree of subject is required higher.
3, the space scale for subject is relatively larger, and the depth of field of intelligent terminal 11 likely cannot hold the problem of all parts of subject, and the method for solution is:
(1) adopt camera lens combination or aperture that the depth of field is bigger as far as possible.
(2) subject is from intelligent terminal's camera lens a little further.
(3) adopted many focal lengths exposure method that subject is shot by intelligent terminal's array, the exposure of described many focal lengths refers to that the many focal lengths taked within the depth of field that cannot be contained in camera lens for subject repeatedly shoot, and obtains the multiple pictures that burnt section all differs.Adopt the method that many focal lengths expose, herein be repeatedly the exposure of twice or more than twice, the exposure of many focal lengths refers to the way that the many focal lengths taked within the depth of field that cannot be contained in camera lens for subject repeatedly shoot.The burnt section of every photo all differs, and computer program thus can be allowed to extract characteristic point or the characteristic parameter of subject correspondence difference Jiao's section from a series of photo respectively when later stage three-dimensional reconstruction.
The concrete scheme of many focal lengths exposure can be realized by the one of following three kinds of schemes or combination in any scheme:
(1) when intelligent terminal's array adopts an intelligent terminal 11 to shoot, the position of described intelligent terminal 11 equipment is fixed, same subject is shot according to different Jiao is poly-by described intelligent terminal 11 respectively simultaneously；
(2) when intelligent terminal's array adopts an intelligent terminal 11 to shoot, described intelligent terminal 11 equipment is gathered according to different positions and different Jiao, respectively same subject is shot；
(3) when intelligent terminal's array adopts multiple intelligent terminal 11 to shoot, different Jiao is set for each intelligent terminal 11 and gathers, then allow same subject is shot.
Adopt intelligent terminal's array apparatus, then the focusing that the intelligent terminal's reasonable arrangement that can be different is different, the multiple photos so collected at synchronization just contain enough characteristic points of subject difference Jiao's section.But do so needs intelligent terminal's array closeness high, and advantage is that instantaneous completing is taken pictures.If intelligent terminal's array closeness is relatively low, then each equipment can be adopted repeatedly to adjust focusing parameter and to realize, but the static degree of subject is required higher.
