In Fig. 1：1st, it is imaged microscope group；2nd, Amici prism；3rd, detector one；4th, detector two.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with accompanying drawing and specific implementation
Example, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only explaining this hair
It is bright, without being construed as limiting the invention.
Fig. 1 is refer to, the embodiment of the present invention provides a kind of method based on double camera spectroscopic imaging increase visual field, including such as
Lower step：
Step 1, there is provided an imaging microscope group 1, diaphragm (not showing on figure), detector 1, detector 24, the diaphragm cloth
After the imaging microscope group 1, the light come out from the imaging microscope group 1 punishes light in diaphragm, and passes through the detector for office
One 3 receive reflected light, and transmitted light is received by the detector 24；Specifically, spectroscope is provided with the diaphragm, and
And spectroscope is the clever border 3 of light splitting.
Step 2, the different field ranges for having overlapping region are received by the detector 1 and detector 24；
Step 3, required big view field image is spliced into by image registration.
In one embodiment, the overlay region for the position adjustment visual field for moving the detector 1 and detector 24 can be passed through
Domain, then required big view field image is spliced into by image registration.
In one embodiment, the angle of visual field of the imaging microscope group 1 is more than the detector 1 and the detector 24
The angle of visual field.
In one embodiment, transmitted light is equal with energy of reflection light after the Amici prism 2 light splitting.
With reference to figure 1, the embodiment of the present invention also provides a kind of system based on double camera spectroscopic imaging increase visual field, system bag
Include imaging microscope group 1, Amici prism 2, detector 1, detector 24.The diaphragm of system is located at imaging microscope group 1 finally a piece of lens
Between detector 24, ensure that back work distance should be greater than the size and detector 24 of Amici prism 2 when being designed like object lens
Flange apart from sum.The center of Amici prism 2 is placed in stop position on axle, the chi of Amici prism 2 can be compressed to greatest extent
It is very little.The transmission potential of Amici prism 2 is 1 with reflected energy:1, and because detector 1 and detector 24 share imaging microscope group
1, therefore transmission has uniformity with reflection two-way image.Detector 1 is used for the part for receiving reflected image, detector two
4 are used to receive the part of transmission image, and the image f iotaeld-of-view for making detector 1 be received from detector 24 is different but has one
It is fixed overlapping, big view field image can be spliced into by image registration, the field range of stitching image can be by adjusting detector 1
It is adjusted with the relative position of detector 24.Compared with traditional multiple video camera shooting images splicing, detected in the present invention
Device 1 shares an imaging microscope group 1 with detector 24, ensure that the source of two-way image is identical, and making need not before image mosaic
Color, brightness calibration are carried out, stitching portion has more preferable visual effect without separator bar, while improves the speed of image mosaic,
It is more suitable for the occasion high to image mosaic requirement of real-time.The present invention, which breaches small target surface detector, can not make full use of imaging
The drawbacks of microscope group full filed, equivalent to the cost for having saved an imaging microscope group, there are wide market prospects.
The embodiment of present invention described above, is not intended to limit the scope of the present invention..Any basis
