Fig. 1 is the generation method implementation process schematic diagram of the embodiment of the present application 3-D image, and this method is applied to have three
The terminal for tieing up imaging function carries out following explanation in conjunction with Fig. 1:
Step S101 receives open command.
Here, open command is used to open the project structured light component of the three-dimensional structure of building target object.When receiving
When open command, the mode of laser group triggered in the project structured light component projects speckle point to the target object.The knot
Structure light projection component includes at least: mode of laser group (for example, internal illumination device be VCEL laser dot-matrix transmitter) and comprising
The camera etc. of infrared camera；Wherein, VCEL can be used as the light source of structure light, for launching speckle laser, for example, using
940 nanometers (nm) of near-infrared VCSEL light source, the light source as structure light.It, will using mode of laser group in a specific example
Lasing fluorescence point spreads angled spot pattern, projects on target object, to form hot spot figure.
Step S102 determines the current optical power value of the project structured light component.
Here, the current optical power value of the mode of laser group in project structured light component is determined.After receiving open command,
Mode of laser group projects speckle point to target object, determines the current optical power value of the mode of laser group.
Step S103 is adjusted the current optical power value based on default optical power value.
Here, which is compared with default optical power value, if current optical power value is not equal to pre-
If optical power value, current optical power value is adjusted, so that current optical power value is equal to default optical power value.
Step S104 is acquired the target object when the current optical power value reaches default optical power value,
Generate the 3-D image of the target object.
Here, when current optical power value is equal to default optical power value, firstly, using infrared in the project structured light component
Camera, acquisition mode of laser group project speckle point to the target object, obtain spot figure；Then, based on the spot figure and in advance
If standard hot spot transmitting position and to the gauged distance between projective object, determine the depth map of the target object, finally,
Using the depth map, the 3-D image of the target object is generated.
In the embodiment of the present application, by adjusting the current optical power value of project structured light component, make working as mode of laser group
Preceding optical power value is maintained at default optical power value, ensure that the consistency of performance of different project structured light components, to guarantee
The consistency of product promotes user experience.
The embodiment of the present application provides a kind of generation method of 3-D image, and Fig. 2 is the life of the embodiment of the present application 3-D image
At the another implementation process schematic diagram of method, following explanation is carried out in conjunction with Fig. 2:
Step S201 receives the open command, to trigger the mode of laser group in the project structured light component to described
Target object projects speckle point.
Here, after receiving open command, the internal illumination device (for example, VCEL) in mode of laser group is triggered to target
Object projects speckle point.
Step S202 determines the current optical power value of the mode of laser group in the project structured light component.
Here, if projecting spot to target object using the VCEL in mode of laser group, current optical power value is
The optical power value of VCEL projection spot.
Step S203 is determined when the current optical power value is not equal to default optical power value for being the structure light
Project the present current value of the mode of laser group power supply in component.
Here, the process of default optical power value is determined are as follows:
The first step generates M 3-D images for sample object.
In a specific example, sample image is thrown using the mode of laser group with different optical power values first
It penetrates, obtains multiple spot figures, then, transmitting position based on preset standard hot spot and to the gauged distance between projective object
With the hot spot figure, the depth map of the sample image is determined, to generate the 3-D image of sample image based on the depth map.
Second step determines N 3-D images for meeting preset condition in the M 3-D images.
In a specific example, the preset condition includes at least following one: the accuracy of the 3-D image of generation
Meet default accuracy threshold value, the picture quality of 3-D image meet predetermined quality threshold (for example, image definition, brightness or
Contrast etc.) or the distortion factor of 3-D image etc..
Third step, by the smallest optical power value in the N corresponding N number of optical power values of 3-D image, as described pre-
If optical power value.
In a specific example, by optical power value the smallest in N number of optical power value, as default optical power value, so that
The terminal of bearing structure light projection component reaches default optical power value by reducing electric current, so that the power consumption of the terminal is saved,
But also improve eye-safe surplus.
Step S204 determines the ratio between the present current value and the current optical power value of the project structured light component
Example.
Here, the current value of mode of laser group optical power value corresponding with the current value is directly proportional, and step S204 can be with
It is the ratio for determining any current value and the corresponding optical power value of the current value.
Step S205 is based on the ratio and the default optical power value, adjusts the present current value, described in changing
Current power value.
Here, since the current value of mode of laser group optical power value corresponding with the current value is directly proportional, so based on electricity
The ratio of flow valuve and the corresponding optical power value of the current value, that is, can determine current value corresponding to default optical power value, be based on this,
Present current value is adjusted to current value corresponding to default optical power value, so that current power value is adjusted to default optical power
Value.For example, optical power of the VCEL in 1A is 1000 milliwatts (mW), then current value optical power value corresponding with the current value
Ratio is (1A ÷ 1000mW).
Above-mentioned steps S202 to step S205 gives realization " based on default optical power value, to the current optical power value
Be adjusted " process, in this process, by the smallest smooth function in the corresponding optical power value of 3-D image for meeting preset condition
Rate value is as default optical power value, then by adjusting the current value of mode of laser group, so that the current value of the mode of laser group reaches
Default optical power value also reduces end to not only ensure that consistency of performance when different terminals carry out 3-D image generation
The power consumption at end.
Step S206, when the current optical power value reaches default optical power value, using the mode of laser group to described
Target object projected spot.
Here, when current optical power value is adjusted to default optical power value, using the VCEL in mode of laser group to target object
Project speckle.
Step S207 acquires the hot spot on the target object, obtains hot spot figure.
Here, using the hot spot on the infrared camera acquisition target object equal with the wavelength of the mode of laser group, thus
Hot spot figure is obtained, as shown in figure 4, hot spot Figure 42 is to be acquired to obtain to the hot spot on target object 43 using infrared camera
's.
Step S208, transmitting position based on preset standard hot spot and to gauged distance between projective object and described
Hot spot figure determines the depth map of the target object.
Here, the step S208 can be realized by following procedure: firstly, determining target object in the hot spot figure
The hot spot set that the changed region of appearance includes；Then, be based on the hot spot set and the gauged distance, determine described in
The target range of the transmitting position and the target object of each hot spot in hot spot figure；Finally, being based on the target range, obtain
The depth map of the target object.As shown in figure 4, with reference to contained in Figure 41 the transmitting position of preset standard hot spot with wait throw
The gauged distance between object is penetrated, then with reference on the basis of Figure 41 the corresponding depth map 43 of hot spot Figure 42 will can determine.
Step S209 is based on the depth map, generates the 3-D image of the target object.
Here, the depth map, it can be understood as the point on target object in reality scene, depth camera is scanned
To each frame data not only include the point in scene colored RGB (Red Green Blue, RGB) image, further include
Distance value of each point to the vertical plane where depth camera.This distance value is referred to as depth value, these depth values are common
Constitute the depth map of this frame.That is, depth map can regard a secondary gray level image as, wherein each point in image
Gray value represents the depth value of this point, i.e., the actual distance of vertical plane where position to camera of this in reality.
Then, for example, for the point M on target object in reality scene, depth camera can obtain imaging of the point M in RGB image
The distance of vertical plane (i.e. X, Y plane) where point XM, and point M to camera, this distance is the depth value of M.With phase
Seat in the plane is set to origin, and camera institute is Z axis towards direction, and two axial directions of the vertical plane of camera are X, Y-axis, can establish camera
Partial 3 d coordinate system；There is corresponding three-dimensional coordinate hence for the every bit in depth map, then sitting based on these three-dimensionals
Mark, can construct the three-dimensional structure of target object, to obtain the 3-D image of the target object.
Above-mentioned steps S206 to step S209 gives a kind of realize " when the current optical power value reaches default optical power
When value, the target object is acquired, generates the 3-D image of the target object " mode will swash in this approach
The current power value of optical mode group is adjusted to default optical power value, by reference to standard hot spot preset in figure transmitting position with to
Gauged distance between projective object calculates the transmitting position of each hot spot in glossing up figure at a distance from target object, thus
Depth map, and then the three-dimensional structure based on depth map building target object are obtained, the low-power consumption of terminal is not only ensure that, also protects
The picture quality of obtained 3-D image is demonstrate,proved.
In the embodiment of the present application, based on different optical power values, multiple 3-D images of sample are constructed, then, from more
The 3-D image for meeting preset condition is filtered out in a 3-D image, finally, the 3-D image for meeting preset condition is corresponding
The smallest optical power value in multiple optical power values, as default optical power value, by adjusting current system, by working as mode of laser group
Preceding optical power value is all adjusted to default optical power value, this way it is ensured that the consistency of optical power, the speckle point energy of different terminals
Density is identical, so that different terminals, there is identical performance；And default optical power value is in entire optical power limit on the lower side
Position saves the power consumption of terminal, the user experience is improved so terminal is to reach default optical power by reducing electric current
Sense.
The embodiment of the present application for ease of understanding carries out following say to the process for generating 3-D image using structure optical assembly
It is bright:
Firstly, by near infrared laser, it will be on the dot projection to target object with certain structure feature；Secondly,
It is acquired by infrared camera identical with the wavelength of the near infrared laser, the hot spot on target object obtains hot spot figure；Again
Secondary, since the depth of extraterrestrial target object is different, the collected hot spot structure of infrared camera can change, therefore pass through mesh
Each point in target object can be obtained using triangle principle in position and deformation degree of the mark object in the image that capture obtains
Depth information to get arrive target object depth map；Finally, being based on the depth map, the three-dimensional knot of target object can be constructed
Structure obtains 3-D image.As shown in Figure 3A, firstly, the infrared transmitter 31 in mode of laser group passes through Speckle Grating 32 to mesh
Mark object 33 shows projected spot, and infrared camera 34 acquires the hot spot on target object 33, obtains the hot spot figure of black and white, such as
Shown in Fig. 3 B, hot spot Figure 35 is that infrared camera 34 acquires what the hot spot on target object 33 obtained；Then, based on for showing
The transmitting position of preset standard hot spot and to the gauged distance between projective object with reference to figure and the speckle pattern, determine target
The depth map of object, to obtain the 3-D image of the target object.
In the related art, mode of laser group internal illumination device is VCEL, and VCEL is worked it out by wafer.Due to crystalline substance
The reasons such as process variations, will cause under same current, the optical power meeting of different VCEL in difference of circle itself and VCEL production process
There is very big difference.For example, the luminous power variation range of VCEL is 625mW to 1125mW, least work under identical 1 peace (A) electric current
Difference is very big between rate and maximum power；The consistent sex differernce of optical power caused by sample is big, will cause the speckle point of different mobile phones
Energy density is different, in turn results in different mobile phone operating distances differences, consistent sexual deviation is serious, influences user experience.If logical
It crosses and selects to realize optical power consistency, the bad VCEL of a large amount of quality can be generated, and VCEL price can rise at double, lead
Cause increased costs too many.By the wafer for selecting consistency good, optical power consistency can also be promoted, but equally to be increased into
This.
Based on this, the embodiment of the present application provides a kind of generation method of 3-D image, by adjusting project structured light component
The present current value of power supply, with lift structure optical property consistency.In the embodiment of the present application, experiment is first passed through, not shadow is obtained
Optical power value is all adjusted to by the optical power value rung under the 3-D image behavior pattern generated then by adjusting current system
The optical power value；To ensure that homogeneity of product, so that all project structured light components, there is identical performance.
The embodiment of the present application is as follows by electric current adjustment optical power process:
The first step, Unclosing structure light projection component.
Current optical power value A is tested or read to second step.
Here, due to the characteristic of VCEL, the optical power of VCEL is directly proportional to electric current, thus only it is to be understood that any one
The corresponding optical power value of electric current, so that it may determine the corresponding optical power value of another electric current.For example, optical power of the VCEL in 1A
500mW ÷ 1000mW × 1A=0.5A is set by electric current if default optical power value is 500mW for 1000mW.
Third step adjusts current value based on default optical power value and above-mentioned ratio, so that current optical power value reaches default
Optical power value.
Here, firstly, testing whether current optical power value has reached default optical power value, if not up to, led to
Adjustment current value is crossed, to change current optical power value.For presetting the setting of optical power value, need through a large number of experiments, to survey
Hot spot figure and the depth map under different optical power values are tried, to obtain multiple 3-D images under different optical power values, will be met
The smallest optical power value in corresponding optical power value in the 3-D image of preset condition (for example, meeting recognition result accuracy),
It is determined as default optical power value.
In the embodiment of the present application, in this way using optical power value the smallest in the multiple optical power values for meeting preset condition as
Default optical power value, so that most of terminal is all to reach default optical power value by reducing electric current, to not only save end
The power consumption at end also improves eye-safe surplus.
