Description
Technical field
The present invention relates to a kind of panoramic picture acquisition technique more particularly to a kind of realization whole day ball panoramic picture acquisition process
Technology.
Background technology
At present, widely used panoramic picture harvester is the sensor by multichannel by the image in the different angle visual field
It is collected respectively, needs the imaging sensor of at least two-way, mainstream uses two-way, three tunnels, four tunnels, five tunnels, six tunnels
Even more acquisition panoramic pictures.It is more than 360 degree of visuals field in the covering of the multichannel angle of view, although panorama can also be collected
Image, but due to being the image independently acquired with the different sensor of polylith in the different visuals field, polylith sensor chip
The difference of photosensitive parameter, often there are different sensors the image collected there are colour temperature, the difference of the bright imaging effects such as dark,
Additionally due to polylith sensor chip the image collected signal cannot be accomplished to synchronize well, also result in for same fortune
Dynamic object, the posture in the imaging of different sensors, the nonsynchronous situation in position occur.
Meanwhile multisensor not only requires at least to support two-way using more demanding to the picture processing chip of rear end
Video input and picture synchronization, and also have higher requirements to indexs such as hardware interface, driving, computing capabilitys, at present on the market
The cost of such processor is generally higher, and development difficulty and cost are also higher, it is difficult to match with existing image processing module
It closes and uses；Module needs multiple sensors and camera lens simultaneously, increases the cost of additional modules.
Invention content
Deficiency discloses a kind of panoramic picture harvester to the present invention according to prior art.The present invention is in order to overcome multichannel
The defects of imaging image quality of multi-sensor panoramic image collecting device has differences, picture is asynchronous, cost is higher, provides a kind of list
The panoramic picture harvester of sensor, apparatus of the present invention only need a piece of sensor chip that can make realization to panoramic picture
Acquisition, significantly reduces cost and overcomes the lacuna of different sensors imaging difference.
The invention is realized by the following technical scheme：
Panoramic picture harvester, including fish eye lens module, imaging sensor and signal transmssion line, it is characterised in that：
The fish eye lens module has two groups, and optical axis is overlapped, is oppositely disposed in same optical axis both ends, two groups of flakes
Camera lens module optical center connection is provided centrally with prism, and the image for having below prism while acquiring the imaging of two fish eye lens modules passes
Sensor.
The fish eye lens module is made of multi-disc lens, and the angle of view is more than 180 degree.
The two fish eye lenses module, prism and imaging sensor are arranged symmetrically along the perpendicular bisector of two groups of camera lens lines.
Described image sensor is ccd image sensor or cmos image sensor.
The optical axis and the normal angle at 45 ° in prismatic reflection face.
The panorama of this patent meaning refers to 360 ° of horizontal field of view angle, the whole day ball panoramic view at 360 ° of vertical field of view angle.
It is front and rear that there is panoramic picture harvester two of the present invention the fish eye lens module of ultra-wide angle to be divided into panoramic view
Two parts visual field, is imaged respectively, and imaging optical signal is projected after ultra-wide angle lens set among camera lens module
On the reflecting surface of prism both sides, by the reflection of prism, it is directly imaged on the left and right region of same sensor target surface simultaneously.This hair
Bright imaging sensor has an intermediate zone between the imaging region of left and right, dry between front and rear two-way optical signalling for being isolated
It disturbs, in order to which more the sufficient imaging area using imager chip, imager chip use length-width ratio as 16:9 optical element, and
Edge trimming processing is carried out on the image of sensor is finally incident upon.As a result of the high-resolution image sensing of big target surface
Device, 200 ten thousand to 600 ten thousand even higher imaging resolutions can be realized by being ultimately imaged effect.Due to only needing a piece of image
Acquisition chip, final output are viewdata signal all the way.
The invention has the advantages that panoramic picture harvester of the present invention realizes different visual field image quality in panoramic picture
Complete unity and picture it is fully synchronized；This panoramic picture harvester only has video output all the way, greatly letter simultaneously
Change the data acquisition session and panoramic mosaic task of the processing of later stage panoramic picture, reduce difficulty and cost；Reduce image
Sensor chip quantity and number of shots, reduce the cost of image capturing system, image quality higher, and image quality is more stable.

Specific embodiment
The present invention is specifically described below by embodiment, embodiment is served only for carrying out the present invention further
Explanation, it is impossible to be interpreted as limiting the scope of the invention, those skilled in the art's content according to the present invention is made
Some nonessential modifications and adaptations also belong to the scope of protection of the invention.
With reference to Fig. 1 to Fig. 4.
Panoramic picture harvester, including fish eye lens module, imaging sensor 6 and signal transmssion line, fish eye lens mould
Group has two groups, is preceding visual field fish eye lens module 1 and rear visual field fish eye lens module 2 respectively, two fish eye lens module optical axis phases
Mutually overlapping, is oppositely disposed in same optical axis both ends, and two groups of fish eye lens module optical center connections are provided centrally with prism 4, prism 4
Lower section has while acquires the imaging sensor 6 of two fish eye lens modules imaging.
Fish eye lens module is made of multi-disc lens, and the angle of view is more than 180 degree.
Two fish eye lens modules, prism 4 and imaging sensor 6 are arranged symmetrically along the perpendicular bisector of two groups of camera lens lines.
Imaging sensor 6 can select ccd image sensor or cmos image sensor.
The normal angle at 45 ° of optical axis and 4 reflecting surface of prism.
As shown in Figures 1 to 4, preceding visual field fish eye lens module 1, rear visual field fish eye lens module 2, prism 4 are in same light
On axis, the optical axis is vertical with the normal of 6 imaging target surface of imaging sensor.Prism 4 is located at the surface of imaging sensor 6, prism 4
For prism, the light of forward and backward visual field is synchronized by being arrived after the imaging of fish eye lens module optically focused by the reflective surface of prism 4
Imaging sensor 6.Lens mount 3 provides support for other optical components, and imaging sensor 6 and soft arranging wire junction block 7 are distributed in
On image acquisition circuit plate 5.Using sealing waterproofing design, the influence of completely isolated external world's veiling glare, dust and steam.
As shown in the figure, prism 4 is located at the surface of imaging sensor 6, tip faces the 1/ of 6 length of imaging sensor
At 2 lines of demarcation.The optical axis of preceding visual field fish eye lens module 1 and the normal angle at 45 ° in the front-reflection face of prism 4, rear visual field flake
The optical axis of camera lens module 2 and the normal angle at 45 ° in the back reflection face of prism 4.Due to the influence of the machining accuracy at prism tip, need
It will there are the gap intermediate zones of pre- 3mm between front and rear view field imaging.Picture signal is passed by 7 connection signal of soft arranging wire junction block
Defeated line output.
On the one hand apparatus of the present invention become single from the structure of original multichannel camera lens+multiple sensor+image mosaic module
The structure of the multigroup camera lens in road+single channel sensor, make integral module compacter from structure, it can be achieved that final products it is small-sized
Change, improve the reliability of module, cost has been saved from hardware；The synchronization of the multiple portions of another aspect panorama exposes
Light, integration work are optically directly solved till now from original realized using circuit arrangement, reduce panorama technology
