Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing：
Fig. 1 is the operation principle schematic diagram that near-infrared 3D in the embodiment of the present invention is combined real-time safety-protection system.
Specific embodiment
In order to be more clearly understood to technical characteristic of the invention, purpose and effect, now compare accompanying drawing and describe in detail
Specific embodiment of the invention.
As shown in figure 1, the near-infrared 3D in a preferred embodiment of the invention is combined real-time safety-protection system includes two closely
Infrared photography unit 1, visible ray filter unit 2, near-infrared laser projecting cell 3 and processing unit.
Two near-infrared image units 1 are set towards monitoring direction, and capture direction in angle, right from different directions
Monitoring direction carries out scanning of taking pictures.In other embodiments, the quantity of near-infrared image unit 1 can also be more than two, from difference
Angle towards monitoring direction to monitor direction object 4 carry out scanning of taking pictures.
Visible ray filter unit 2 is arranged on the capture direction of the near-infrared image unit 1, allows near infrared light to described
Near-infrared image unit 1 passes through, and the near infrared light on the upward object 4 of monitoring side is photographed by near-infrared image unit 1.
Near-infrared laser projecting cell 3 makes the surface of object 4 to the upward projected graphics shape near infrared light of object 4 of monitoring side
Near infrared light is distributed with, allows near-infrared image unit 1 to shoot the near infrared light on object 4.
Processing unit is taken the photograph according to the angle angle of the default near-infrared image unit 1, distance and the near-infrared
As unit 1 photographs the diagram shape near infrared light projected on object 4, by geometric algorithm, the object 4 upward to monitoring side enters
The real-time 3D imagings of row, such that it is able to show the 3D imaging models of the objects such as people 4 on the display device, allow people to see truer,
The 3D model datas of object 4, such as face shape of people, the stature shape model data of people can be obtained simultaneously, help follow-up
Obtain the exact shape data characteristics of object 4.
Preferably, the frame per second of near-infrared image unit 1 is per second not less than 120 frames, with energy captured in real-time near infrared light image,
The accurate shift action for obtaining object 4.
Further, it is seen that light filter unit 2 can allow object 4 by more than 760nm, the near infrared light of below 1000nm
On near infrared light by near-infrared image unit 1.In other embodiments, it is seen that light filter unit 2 also can be by other
Wavelength but the light not caught by near-infrared image unit 1.
Preferably, the wavelength of near-infrared laser projecting cell 3 is 840nm, is somebody's turn to do with the surface distributed of object 4 of monitor area
The near infrared light of wavelength.
Further, the near infrared light of the projection of near-infrared laser projecting cell 3 is web, can be in the thing of monitor area
The surface of body 4 forms the IR distorted along the male and fomale(M＆F) on the surface of object 4, is deformed with the male and fomale(M＆F) on the surface of object 4.
The lines distortion that near-infrared image unit 1 shoots the web on the photo for coming from different perspectives is different
, and then processing unit can be allowed according to the angle angle of the default near-infrared image unit 1, distance and described near red
What outer image unit 1 was photographed projects the near infrared light web on object 4, upward to monitoring side by geometric algorithm
Object 4 carry out real-time 3D imagings.
Preferably, the near infrared light of the projection of near-infrared laser projecting cell 3 is lattice-like pattern, allows and projects the table of object 4
The near infrared ray in face is uniformly distributed, and makes the 3D imagings to object 4 more accurate.Generally, the lines spacing of lattice-like pattern is
1mm, in other embodiments also greater than 1mm or less than 1mm, generally, spacing is smaller, the model of the object 4 that 3D is imaged out
Resolution ratio it is higher.
In certain embodiments, the shape of the grid of lattice-like pattern includes the one kind or many in square, rhombus, triangle
Kind.In other embodiments, the projection of near-infrared laser projecting cell 3 can also be multiple line segments for extending in different directions or
Curve, can be after projection along the male and fomale(M＆F) torsional deformation on the surface of object 4.
Further, processing unit is according to the angle angle of the default near-infrared image unit 1, distance and described
Near-infrared image unit 1 photographs the near infrared light figure for projecting, and the human body upward to monitoring side carries out real-time 3D imagings.
In monitor area someone activity, the 3D imagings to human body, collection can be realized under conditions of people does not discover
The 3D features of human body, for subsequently transferring after the 3D features of human body are analyzed, help track down.Taken the photograph due to using near-infrared
As unit 1, only to infrared imaging, do not influenceed by outdoor environment, daytime at night realizes same monitoring effect.
Preferably, safety-protection system also includes carrying out monitoring direction the visible image capturing unit 5 of real-time recording, it is seen that light is taken the photograph
The centre of near-infrared image unit 1 is may be located at as unit 5, to the video image of monitor area camera plane, human body is obtained
Plane characteristic.With reference to the 3D features of collection, can be when needing while transferring the plane picture of acquisition and quantifying what is measured
3D characteristics, realize real-time volume security protection, can help quick lock in personnel.
It is to be appreciated that above-mentioned each technical characteristic can be used in any combination and unrestricted.
Embodiments of the invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair
