Distance (object distance) between lens 4, owing to the focal length (f) of imaging len 4 is definite value, imaging len 4 and imaging processing and control simultaneously
The position v of system 6 processed fixes (image distance determines), then drawn the testee distance (thing away from imaging len 4 by lens imaging theory
Away from u) being determined, and then the corresponding pass between graphical rule with actual testee can be drawn in imaging processing and control system 6
System, uses this corresponding relation can realize the measurement of testee, is same medium owing to closing the medium inside and outside chamber 12
(air), the curvature of correction lens 4 can produce impact to testee to light refraction, and this impact is steady state value, Ke Yitong
Cross the algorithm in imaging processing and control system 6 to remove this impact.
When underwater camera shoots in water, the medium residing for observed object there occurs change, owing to light exists
Refractive index ratio light in water is much bigger in the refractive index of air, so light is by correcting lens 2 and imaging len 4 in imaging
Process and control system 6 formed in difference the most relatively air measured during image big, in order to reduce this species diversity and realize surveying
Sameization of amount result, native system is provided with the water that enters of underwater camera and detects device 10, enters water detection device 10 according to electrical conductivity
Difference distinguish the medium in shooting environmental, and then judge the kind of medium in shooting environmental and corresponding refractive index,
The refractive index that the refractive index measured to enter water detection device 10 is measured with diastimeter 5 is compared and switches corresponding becoming
As pattern and algorithm, the impact on image of the difference of reduction transmission medium refractive index.
Further, since the light in object being measured local environment can change at any time, this change can affect measured object
Body utilizes, in imaging processing and the color change of control system 6 image, impact, the process that image is carried out by color and gray value, this
Utility model is set to be positioned in same media with testee, when camera shoots under water, and the color change meeting of blank 1
It is recorded in each sub-picture, it is possible to use testee is restored in the blank 1 color in different medium and light and shade change
Image in imaging processing and control system 6.
The foregoing is only a kind of embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
