Description
Technical field
This application involves a kind of focusing structural optical projection devices, more particularly to a kind of auto-focusing structured light projecting device
And the depth camera configured with the auto-focusing structured light projecting device and the electronic equipment configured with the depth camera.
Background technology
With development in science and technology, depth camera technology is more and more perfect, such as imaging effect is more preferably, therefore depth camera is also got over
To be applied to various electronic equipments more.
As the important composition component of depth camera, the function of structured light projecting device directly affects entire depth camera
Function, such as structured light projection module drop shadow effect are poor, and entire depth camera imaging can be caused of poor quality.
Existing structure optical projection device is fixed structure, that is, in use, the Optical Parametric of structured light projecting device
Number, focus etc. will not change.Thus, the shooting distance for the existing depth camera being made of project structured light device is
One fixed range (the similar depth of field).It goes beyond the scope once extraterrestrial target is super, structured light projecting device just can not will be high-quality
The structured light projection of amount is sent to extraterrestrial target surface, so that depth camera image quality is deteriorated.In other words, structure light is thrown
The recognizable region (i.e. depth of focus) of image device is fixed, is not suitable with large-scale extraterrestrial target.That is, structure light is projected in the range
The spot size on extraterrestrial target surface meets reception and requires, and once exceeds the range, and spot size does not just meet reception and requires.
It substantially can be regarded as beyond after the range, hot spot excessive can not be received, be identified by receiving module, to influence depth phase
Machine imaging effect.
In addition, different shooting distances needs the different convergence depth of field, the hot spot mistake that otherwise structured light projecting device provides
It will interfere with each other greatly, can not ensure accurate recognition effect.
In addition, in the ideal situation, after being collimated by the collimation lens of structured light projecting device, diffraction light department of the Chinese Academy of Sciences diffraction
The light beam of (beam splitting) should be parallel, i.e., at any position of space, the spot size that structured light projecting device provides is consistent.
But due to being inevitably present error in optical component manufacture, assembling, collision process, so light beam can not be accomplished completely
It is parallel, to which spot size can change.And spot size can then influence the depth of focus of structured light projecting device, to influence to connect
The reception of module is received, and finally influences recognition effect.
In addition, when converging to human eye by projecting the light beam of module transmission, human eye will be damaged, therefore be transmitted through sky
Between the beam energy of target surface cannot be excessive, and this also will greatly influence transmission range.To solve this problem, it can adopt
With such as under type, the i.e. focal length or focus of active accommodation colimated light system so that light does not converge on extraterrestrial target surface, to drop
As low as the energy density up to the surface (for example, human eye), or the position of the mobile hot spot being formed on extraterrestrial target surface, make
It must avoid the sensitive parts such as human eye.
At least in above-mentioned reason, present depth camera is more to be arranged at electronic equipment front end, is taken the photograph as preposition
As head, to only need to provide the imaging of short distance.
But with the development in market, short distance shooting imaging is unable to meet demand, it is therefore desirable to meet increase shooting away from
From the depth camera without influencing imaging effect.And to meet the demand, then need the structured light projection of drop shadow spread's bigger to fill
It sets.
