Description
Technical field
The present invention relates to a kind of camera module more particularly to a kind of panoramic cameras, the wherein panoramic shooting
The optical axis of the imaging lens of machine is set non-homocentric.
Background technology
In recent years, being constantly progressive with technology, virtual reality technology (VR, virtual reality) obtain quick hair
Exhibition.Virtual reality technology includes simulated environment, perception, the natural many aspects such as technical ability and sensing equipment.Simulated environment is related to
The visual perception of user, occupies critical role in virtual reality technology.In virtual reality technology, simulate and generate and is true to nature
Three-dimensional artificial image needs panoramic camera to provide object or scene panoramic picture.Panoramic camera has overturned traditional cameras
Limitation, have and cover the full visual angle camera lens in 360 degree of spaces, can capturing object simultaneously, all around institute is angled and right up and down
It carries out video-photographic, and beautiful scenery is recorded to zero dead angle in image.Therefore, panoramic camera is adapted to shoot vast landscape
It meets scene, such as ball match, concert according to, construction landscape, more people, and a ball-type photo that can move freely can be preserved into
Or one section of ball-type film, it to be allowed particularly to arrange in pairs or groups by browsing or present in a manner of more polynary, virtual reality (VR) eye
Mirror allows user to obtain experience on the spot in person.
But there are still problems in imaging for existing panoramic camera.First, existing video-photographic equipment by
The limitation of its structure and function is still only capable of with single visual angle video-photographic.This causes existing panoramic camera to be still difficult to realize list
A imaging lens obtain panoramic picture or image.The panoramic picture that existing panoramic camera is shot is by multiple imagings
Camera lens shoots the image of different angle respectively, is then obtained by splicing.Secondly, usually, existing panoramic shooting equipment
There are multiple imaging lens, panoramic camera carries out editing and splicing to the image of different imaging lens, so as to obtain 360 degree of ranges
Image.For the ease of panoramic camera image clips and splice program according to parameter preset to the images of each imaging lens into
Row editing and splicing and obtain ideal image, these imaging lens of panoramic camera are fixed on predeterminated position, and these into
As the optical axis of camera lens meets at same point.However, the optical axis of these imaging lens of existing panoramic camera meet at it is same
The design of a point leads to it with fixed shape.The fixation of the shape of existing panoramic camera and inalterability, increase
Its manufacture difficulty and cost reduce its scope of application.Again, the design feature of multiple imaging lens of existing panoramic camera
Determine that the structure of existing panoramic camera is complex.However, with the extension of usage time, panoramic camera it is multiple into
As the relative position between camera lens may change.These changes will necessarily influence the quality of final panoramic picture.Finally,
The distortion of traditional cameras can not be reduced or eliminated in multiple imaging lens design of existing panoramic camera.Existing camera shooting
Photographic equipment can generate distortion, that is, so-called " barrel distortion " in imaging.Strong distortion makes picture be bent to arc
Shape, and closer to edge, distortion is more apparent, and optical center position distortion degree significantly weakens.This distortion also influences whether
Spliced panoramic picture or image.Multiple imaging lens design of existing panoramic camera can not be reduced or eliminated this
" barrel distortion ".
Invention content
It is a primary object of the present invention to provide a kind of panoramic camera, wherein the panoramic camera has at least four one-tenth
As camera lens, and the installation position of the imaging lens of the panoramic camera is not limited in fixed position.In other words, the panorama
The installation position of the imaging lens of video camera can be adjusted according to application, to be adapted to different application scene.
It is an object of the present invention to provide a kind of panoramic camera, wherein between the imaging lens of the panoramic camera
Relative position and unfixed design method, reduce panoramic camera assembly difficulty and manufacture cost.
It is an object of the present invention to provide the light of a kind of panoramic camera, the wherein imaging lens of the panoramic camera
Axis is set non-homocentric.In other words, the optical axis of the imaging lens of the panoramic camera is set not through same point.It should
This imaging lens relative position of panoramic camera by the design feature of the homocentric limitation of optical axis, does not allow the panoramic camera strong
Change the reinforcing to some angle scene to photograph.For example, the panoramic camera of the present invention allows two or more camera lenses simultaneously to same
One orientation object or scene capture.
It is an object of the present invention to provide a kind of panoramic camera, the wherein panoramic camera allows in generation image
Before, the optical axis position of each imaging lens is detected in advance, and according to optical axis position testing result, determines Panorama Mosaic side
Formula.The panorama sketch of this Panorama Mosaic mode of the panoramic camera of the present invention panoramic camera more homocentric than existing optical axis
Picture connecting method is more flexible, and can eliminate the inherent shortcoming of the image mosaic mode of existing panoramic camera, such as when existing complete
When the relative position of the imaging lens of scape video camera changes, the Panorama Mosaic method of existing panoramic camera still can not
It makes and being adaptively adjusted.
Another object of the present invention is to provide a kind of panoramic camera, including at least four imaging lens, and it is each
Imaging lens choose larger image range, can expand the selection of effective range in splicing, accordingly even when in use
Camera, which generates slight displacement, will not influence splicing effect.
Another object of the present invention is to provide a kind of panoramic camera, wherein panoramic camera of the present invention is used based on fish
The correction of eyelens module so as to make panoramic camera of the present invention can effectively reduce radial direction barrel distortion and reduction be ultimately imaged it is abnormal
