In other words, structure light video camera head 122 can be further used in demodulation structure light image phase corresponding to each pixel
Position information, phase information is converted into depth information, and depth image is generated according to depth information.
Specifically, compared with non-modulated structure light, the phase information of the structure light after modulation is changed, and is being tied
The structure light showed in structure light image is to generate the structure light after distortion, wherein, the phase information of change can characterize
The depth information of object.Therefore, structure light video camera head 122 demodulates phase corresponding to each pixel in structure light image and believed first
Breath, calculates depth information, so as to obtain final depth image further according to phase information.
In order that those skilled in the art is more apparent from gathering the face of active user and body according to structure
The process of the depth image of body, illustrate it by taking a kind of widely used optical grating projection technology (fringe projection technology) as an example below
Concrete principle.Wherein, optical grating projection technology belongs to sensu lato area-structure light.
As shown in Fig. 9 (a), when being projected using area-structure light, sine streak is produced by computer programming first,
And sine streak is projected to measured object by structured light projector 121, recycle structure light video camera head 122 to shoot striped by thing
Degree of crook after body modulation, then demodulates the curved stripes and obtains phase, then phase is converted into depth information to obtain
Depth image.The problem of to avoid producing error or error coupler, needed before carrying out depth information collection using structure light to depth
Image collection assembly 12 carries out parameter calibration, and demarcation includes geometric parameter (for example, structure light video camera head 122 and project structured light
Relative position parameter between device 121 etc.) demarcation, the inner parameter and structured light projector 121 of structure light video camera head 122
The demarcation of inner parameter etc..
Specifically, the first step, computer programming produce sine streak.Need to obtain using the striped of distortion due to follow-up
Phase, for example phase is obtained using four step phase-shifting methods, therefore the striped that four width phase differences are pi/2, then structure light are produced here
The projector 121 projects the four spokes line timesharing on measured object (mask shown in Fig. 9 (a)), and structure light video camera head 122 gathers
To the figure on such as Fig. 9 (b) left sides, while to read the striped of the plane of reference shown on the right of Fig. 9 (b).
Second step, carry out phase recovery.The bar graph that structure light video camera head 122 is modulated according to four width collected is (i.e.
Structure light image) to calculate the phase diagram by phase modulation, now obtained be to block phase diagram.Because four step Phase-shifting algorithms obtain
Result be that gained is calculated by arctan function, therefore the phase after structure light modulation is limited between [- π, π], that is,
Say, the phase after modulation exceedes [- π, π], and it can restart again.Shown in the phase main value such as Fig. 9 (c) finally given.
Wherein, it is necessary to carry out the saltus step processing that disappears, it is continuous phase that will block phase recovery during phase recovery is carried out
Position.As shown in Fig. 9 (d), the left side is the continuous phase bitmap modulated, and the right is to refer to continuous phase bitmap.
3rd step, subtract each other to obtain phase difference (i.e. phase information) by the continuous phase modulated and with reference to continuous phase, should
Phase difference characterizes depth information of the measured object with respect to the plane of reference, then phase difference is substituted into the conversion formula (public affairs of phase and depth
The parameter being related in formula is by demarcation), you can obtain the threedimensional model of the object under test as shown in Fig. 9 (e).
It should be appreciated that in actual applications, according to the difference of concrete application scene, employed in the embodiment of the present invention
Structure light in addition to above-mentioned grating, can also be other arbitrary graphic patterns.
As a kind of possible implementation, the depth information of pattern light progress active user also can be used in the present invention
Collection.
Specifically, the method that pattern light obtains depth information is that this spreads out using a diffraction element for being essentially flat board
The relief diffraction structure that there are element particular phases to be distributed is penetrated, cross section is with two or more concavo-convex step embossment knots
Structure.Substantially 1 micron of the thickness of substrate in diffraction element, each step it is highly non-uniform, the span of height can be 0.7
Micron~0.9 micron.Structure shown in Figure 10 (a) is the local diffraction structure of the collimation beam splitting element of the present embodiment.Figure 10 (b) is
Along the cross sectional side view of section A-A, the unit of abscissa and ordinate is micron.The speckle pattern tool of pattern photogenerated
Have the randomness of height, and can with the difference of distance changing patterns.Therefore, depth letter is being obtained using pattern light
Before breath, it is necessary first to the speckle pattern in space is calibrated, for example, in 0~4 meter of scope of distance structure light video camera head 122
It is interior, a reference planes are taken every 1 centimetre, then just save 400 width speckle images after demarcating, the spacing of demarcation is smaller,
The precision of the depth information of acquisition is higher.Then, structured light projector 121 is (i.e. current by pattern light projection to measured object
User) on, the speckle pattern that the difference in height on measured object surface to project the pattern light on measured object changes.Knot
Structure light video camera head 122 is shot project speckle pattern (i.e. structure light image) on measured object after, then by speckle pattern and early stage
The 400 width speckle images preserved after demarcation carry out computing cross-correlation one by one, and then obtain 400 width correlation chart pictures.Quilt in space
Position where surveying object can show peak value on correlation chart picture, and above-mentioned peak value is superimposed and passes through interpolation arithmetic
The depth information of measured object is can obtain afterwards.
Most diffraction lights are obtained after diffraction is carried out to light beam due to common diffraction element, but per beam diffraction light light intensity difference
Greatly, it is also big to the risk of human eye injury.Re-diffraction even is carried out to diffraction light, the uniformity of obtained light beam is relatively low.
Therefore, the effect projected using the light beam of common diffraction element diffraction to measured object is poor.Using collimation in the present embodiment
Beam splitting element, the element not only have the function that to collimate uncollimated rays, also have the function that light splitting, i.e., through speculum
The non-collimated light of reflection is emitted multi-beam collimation light beam, and the multi-beam collimation being emitted after collimating beam splitting element toward different angles
The area of section approximately equal of light beam, flux of energy approximately equal, and then to carry out using the scatterplot light after the beam diffraction
The effect of projection is more preferable.Meanwhile laser emitting light is dispersed to every light beam, the risk of injury human eye is reduce further, and dissipate
Spot structure light is for other uniform structure lights of arrangement, when reaching same collection effect, the consumption of pattern light
Electricity is lower.

Referring again to Fig. 2, in some embodiments, step 0131, step 0132, step 0133 and step 0134
To be realized by processor 20.
In other words, processor 20 can be further used for identifying the human face region in scene image, be obtained from depth image
Depth information corresponding with human face region is taken, the depth bounds of people's object area is determined according to the depth information of human face region, and
Determine to be connected with human face region according to the depth bounds of people's object area and people's object area for falling into depth bounds is to obtain personage
Area image.
Specifically, the human face region that the deep learning Model Identification trained can be used to go out in scene image first, with
The depth information of human face region is can determine that according to the corresponding relation of scene image and depth image afterwards.Because human face region includes
The features such as nose, eyes, ear, lip, therefore, depth number of each feature corresponding in depth image in human face region
According to being different, for example, in face face depth image acquisition component 12, depth that depth image acquisition component 12 is shot
In image, depth data corresponding to nose may be smaller, and depth data corresponding to ear may be larger.Therefore, above-mentioned people
The depth information in face region may be a numerical value or a number range.Wherein, when the depth information of human face region is one
During individual numerical value, the numerical value can be by averaging to obtain to the depth data of human face region；Or can be by human face region
Depth data take in be worth to.
Because people's object area includes human face region, in other words, people's object area is in some depth together with human face region
In the range of, therefore, after processor 20 determines the depth information of human face region, it can be set according to the depth information of human face region
The depth bounds of people's object area, the depth bounds extraction further according to people's object area fall into the depth bounds and with human face region phase
People's object area of connection is to obtain personage's area image.
In this way, personage's area image can be extracted from scene image according to depth information.Due to obtaining for depth information
The image of the not factor such as illumination, colour temperature in by environment is taken to ring, therefore, the personage's area image extracted is more accurate.
Referring again to Figure 11, in some embodiments, step 013 processing scene image and depth image are current to extract
People object area of the user in scene image and obtaining personage's area image also includes：
0135：Scene image is handled to obtain the whole audience edge image of scene image；With
0136：According to whole audience edge image amendment personage's area image of scene image.
Referring again to Fig. 2, in some embodiments, step 0135 and step 0136 can be realized by processor 20.
In other words, processor 20 can also be used to handle scene image to obtain the whole audience edge image of scene image, and according to field
Whole audience edge image amendment personage's area image of scape image.
Processor 20 carries out edge extracting to obtain the whole audience edge image of scene image to scene image first, wherein,
Edge lines in the whole audience edge image of scene image include background object in scene residing for active user and active user
Edge lines.Specifically, edge extracting can be carried out to scene image by Canny operators.Canny operators carry out edge extracting
The core of algorithm mainly include the following steps：First, convolution is carried out to scene image with 2D gaussian filterings template to make an uproar to eliminate
