Technical solutions of the utility model are clearly and completely described in embodiment and corresponding attached drawing.Obviously, described embodiment
Only it is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field
The every other embodiment that those of ordinary skill is obtained without making creative work, belongs to the utility model
The range of protection.
Below in conjunction with attached drawing, the technical solution that each embodiment of the utility model provides is described in detail.
- 13 are please referred to Fig.1, the utility model embodiment discloses a kind of light compensating apparatus 100 of multi-lens camera, disclosed
Light compensating apparatus 100 is including multiple light compensating lamps 110 and for the cyclic annular lamp holder on the camera shooting host 200 of multi-lens camera
130。
Cyclic annular lamp holder 130 is the installation foundation of multiple light compensating lamps 110, is equipped with the cyclic annular lamp holder 130 of multiple light compensating lamps 110
It is set in except a plurality of lenses 230 of multi-lens camera, and then implements light filling for a plurality of lenses 230.Multiple light compensating lamps 110 can be with
Along the circumferencial direction dispersed placement of cyclic annular lamp holder 130.Specifically, cyclic annular lamp holder 130 can have inclination mounting surface annular in shape,
Multiple light compensating lamps 110 are along the circumferencial direction dispersed placement for tilting mounting surface.
Plane where cyclic annular lamp holder 130 is usually parallel with the mounting surface of multi-lens camera, and the peace of multi-lens camera
Dress face is usually perpendicular with the axial direction of cyclic annular lamp holder 130.Herein, mounting surface is tilted relative to flat where cyclic annular lamp holder 130
Face is in tilted layout, the axis perpendicular of the plane where cyclic annular lamp holder 130 and cyclic annular lamp holder 130.A kind of specific installation scenario
In, after multi-lens camera installation, the axis of cyclic annular lamp holder 130 vertically extends, and the plane where cyclic annular lamp holder 130 is in
In horizontal plane.
It should be noted that it is that light compensating lamp 110 provides installation foundation to tilt mounting surface so that light compensating lamp 110 also tilts throwing
Light is penetrated, and then the shooting that light compensating lamp 110 is camera lens can preferably be enable to implement light filling, 100 cover lens of light compensating apparatus
Position adjusts all areas of visual visual field.Therefore, mounting surface is tilted to tilt towards the outside of a plurality of lenses of multi-lens camera.
Referring again to Fig. 5, in a kind of specific embodiment, plane where cyclic annular lamp holder 130 and the folder between mounting surface is tilted
Angle A can be 20-40 °.By verification, when included angle A is 20-40 °, the light of light compensating lamp 110 can have enough light to mirror
First 230 projects outside, while can guarantee that multiple light compensating lamps 110 are easier to be spliced into panorama in the shooting side of multi-lens camera again
Light filling region.Specifically, angle between the two can be 32 °.
Light compensating lamp 110 includes illuminator 116 and the inclined light distribution element 112 being located on illuminator 116, inclined light distribution element
112 can be inclined light-distribution lens, the optical element partially with inclined light distributions of realizations such as reflective optical systems.Rotational symmetry optical element (such as
Rotation-symmetric lenses) light distribution can be implemented to light, the optical axis of illuminator is overlapped with the peak light intensity of rotational symmetry optical element,
And then be easier to cause the distant place of light filling and brightness contrast nearby larger, influence the shooting effect of camera lens.Compared to rotation pair
For claiming optical element (such as rotation-symmetric lenses), light that inclined light distribution element 112 is used to send out illuminator 116 is towards remote
Outside from cyclic annular lamp holder 130 is projected, and then the light for enabling to illuminator 116 to send out more is invested at a distance.Inclined light distribution
It is a certain included angle (non-coincidence) between the peak light intensity and the optical axis of illuminator 116 of element 112, multiple light compensating lamps 110 splice
There is larger angle, so that more light projections are away from camera lens between the axis of peak light intensity and multi-lens camera afterwards
Remotely, it realizes remote better light filling, improves the brightness on distant objects surface, while the light filling that can also be reduced nearby is strong
Degree, so as to lower the brightness of image nearby, can finally promote the quality of camera lens acquired image.
It should be noted that above-mentioned inclined light distribution element 112 (is usually in the direction for the axis for being parallel to cyclic annular lamp holder 130
Vertical direction) realize light inclined light distribution.In the axis direction (being usually horizontal plane) perpendicular to cyclic annular lamp holder 130, more benefits
Around the circumferencial direction dispersed placement of cyclic annular lamp holder 130, multiple light compensating lamps 110 splice in circumferencial direction can form light lamp 110 in turn
360 ° of light fillings of gamut.
In the utility model embodiment, the quantity of light compensating lamp 110 can be 3-8, and light compensating lamp 110 can be installed tilting

In the case that camera is mounted on corner, that is, the light compensating lamp towards corner is turned off, other light compensating lamps still suffer from more light
Line is incident to metope, and then is reflexed in camera lens by metope, and the picture quality for eventually resulting in camera lens acquisition is bad.Each is mended
For light lamp 110 when tilting the light filling angle too small of circumferencial direction of mounting surface, the dark space between adjacent two light compensating lamps is long,
And then the blind area b of multi-lens camera nearby can be caused excessive.By verification, each light compensating lamp 110 is in the circle for tilting mounting surface
The light filling angle a of circumferential direction can be 45-90 °.In such cases, the energy on the circumference of cyclic annular lamp holder 130 of each light compensating lamp 110
Enough realize 45-90 ° of light filling, multiple light compensating lamps 110 can the splicing of light filling angle after can form 360 ° of panorama light filling.On
The light filling angle for stating every light compensating lamp 110 is more suitable, can more be flexibly adapted to the installation environment of multi-lens camera, such as schemes
Shown in 8.

It closes and releases, so that the first tooth socket can be relatively moved with the second engaging tooth, and then realize that first support 2521 can be around solid
The circumferencial direction of price fixing 251 moves, it is, circumferencial direction rotation of the first support 2521 along fixed disk 251.
Elastic joint part 2521b is ensured by the elasticity of itself between the first tooth socket 2511 and the first engaging tooth 2521a
Engagement has preferable elasticity, and under the effect of external force, elastic deformation can occur for elastic joint part 2521b, so that first
Positioning lift between engaging tooth 2521a and the first tooth socket 2511, so that the two can relatively rotate.
Lens bracket 252 can also include second support 2522, and second support 2522 is arranged in first support 2521,
Second support 2522 is connected with camera lens 230, and then realizes company of the camera lens 230 by second support 2522 and first support 2521
It connects.
Referring again to Fig. 7-9, in a kind of specific embodiment, first support 2521 may include buckle 2521c,
Avoid holes 2512 are offered on fixed disk 251, buckle 2521c passes through avoid holes 2512 to be clamped with fixed disk 251, and then realizes the
Connection between one holder 2521 and fixed disk 251.The cooperation between 2521c and fixed disk 251 is buckled, can realize first
Holder 2521 can not be moved perpendicular to the disk direction of fixed disk 251, but not influence first support 2521 in fixed disk 251
Circumferencial direction movement.
