For shooting the structure light image modulated through active user；Phase information corresponding to each pixel of demodulation structure light image with
To the face depth image of active user；According to the face depth image and structure light image of active user, active user is generated

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 face depth image further according to phase information.
In order that those skilled in the art be more apparent from according to structure light come gather active user face or
The process of the depth image of body, illustrated below by taking a kind of widely used optical grating projection technology (fringe projection technology) as an example
Its concrete principle.Wherein, optical grating projection technology belongs to sensu lato area-structure light.
As shown in Fig. 6 (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 produce four width phase differences here and beStriped, then structure light throw
Emitter 121 projects the four spokes line timesharing on measured object (mask shown in Fig. 6 (a)), and structure light video camera head 122 collects
Such as the figure on Fig. 6 (b) left sides, while to read the striped of the plane of reference shown on the right of Fig. 6 (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. 6 (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. 6 (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. 6 (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 Fig. 7 (a) is the local diffraction structure of the collimation beam splitting element of the present embodiment.Fig. 7 (b) is edge
The unit of the cross sectional side view of section A-A, abscissa and ordinate is micron.The speckle pattern of pattern photogenerated has
The randomness of height, and can with the difference of distance changing patterns.Therefore, depth information is being obtained using pattern light
Before, it is necessary first to the speckle pattern in space is calibrated, for example, in the range of 0~4 meter of distance structure light video camera head 122,
