Part 114 is successively interspersed, and random point of light-emitting component when cooperating diffraction optical element to use compared to laser emitter 11
The number of cloth, required light-emitting component is less, so as to reduce the cost of laser emitter.
Fig. 2 and Fig. 3 are please referred to, electrooptical device 100 is formed with projection window 40 corresponding with projective module group 10 and and camera
The corresponding acquisition window 50 of mould group 20.Projective module group 10 is used to project laser pattern, phase to object space by projection window 40
Machine mould group 20 is used to receive by the modulated laser pattern of target object by acquisition window 50 to be imaged.In projective module group 10
When shining, firstly, laser projecting apparatus 11 issues laser, laser forms laser pattern after the conversion of exposure mask 12, and laser pattern is again
It is projected away after the adjustment of lens subassembly 13 reaches imaging requirements from projection window 40.For example, projective module group 10 is towards object
Body emits laser pattern, which is speckle pattern.Camera mould group 20 is acquired by acquisition window 50 through target object tune
Make reflected laser pattern.Processor 30 is all connected with projective module group 10 and camera mould group 20, and processor 30 is for handling
Above-mentioned laser pattern is to obtain depth image.Specifically, processor 30 is by the way that laser pattern to be compared with reference pattern, root
According to the difference of the laser pattern and reference pattern to generate depth image.In other embodiments, the laser pattern be with
Specific pattern is the coding structure light image with specific coding, at this moment by extracting the coded structured light figure in laser pattern
Picture is compared with reference pattern so as to get depth image.After obtaining depth image, face knowledge can be applied to
Not, the fields such as 3D modeling.
In the electrooptical device 100 of the utility model embodiment, laser emitter 11 can be cooperated with exposure mask 12, and
Enter exposure mask 12 to emit uniform light for providing area source to generate laser pattern, is by dividing light-emitting component 114
Light-emitting component 114 in the row of first array 116 and second array 118 and the first array 116 and in the row of second array 118
Light-emitting component 114 be successively interspersed, compared to laser emitter 11 cooperate diffraction optical element use when light-emitting component
Random distribution, the number of required light-emitting component is less, so as to reduce the cost of laser emitter.In addition, photoelectricity fills
Set 100 cooperations by camera mould group and processor 30, the laser pattern modulated through target object can be carried out receiving and
Processing is to obtain depth image, so as to apply in fields such as recognition of face, 3D modelings.
