Description
Technical field
The present invention relates to a kind of marine animal monitoring device, especially relate to a kind of middle-size and small-size marine zooplankton depth field imaging monitoring apparatus.
Background technology
Marine zooplankton (the long scope of animal plankton body: 200 μ m-4mm) in marine ecosystems, occupy extremely important position, it is the important nutrition link between in the conventional food chain, its variation of quantity and space distribution are to the function operation of whole marine ecosystems, even Global climate change all can produce vital role.Traditional planktonic organism field observation method adopts simple plankton haul or gathers water sample and carry out planktonic organism abundance or planktonic organism amount (weight in wet base or dry weight) detection, there are many problems in these methods, be difficult to satisfy current planktonic organism research needs, be embodied in: 1. the trawlnet reflection is the level of long distance or the planktonic organism summation that vertical direction is gathered, its spatial resolution can't embody planktonic space population distributed architecture and abundance and change details at several meters even tens meters; 2. trawlnet is easy to damage some colloid floating materials, such as the jellyfish young etc., cause the microscopically in the laboratory to discern; 3. trawlnet can't reflect the mutual relationship between the underwater motion orientation of planktonic organism, behavioural characteristic and the group structure; 4. the sample of gathering needs at the scene sample to be fixed preservation, at making in laboratory observation slide glass, distinguishes counting at microscopically then, needs to consume a large amount of personnel, time and financial resource.And present commercial optics floating material counter (OPC) measuring technique can only carry out size and quantity survey (surveying) to planktonic organism and particle, the detailed information (for example sting water flea with tail worm etc. is arranged) of the discriminating of the species that swim can not be provided.
During to the limited distance target imaging, the sharpness of its optical imagery has certain area requirement, i.e. depth of field scope, and the image that exceeds this field depth presents smudgy.Traditional back reflection type or before penetrate the formula means of illumination, except providing in field depth the illumination, its light beam is also propagated in imaging optical path.These light beams in imaging optical path can cause scattering by the suspended particle in the seawater, bring back scattering and preceding scattering effect, these scattered lights are along with the light beam imaging on digital camera together of imaging, thereby produce degradation influence under image blurring, the contrast, particularly when the imaging device pulls motion under water, because the repeatedly scattering that suspended particle produced that motion is brought is advanced one one and is caused deterioration of image quality, for the kind of differentiating animal plankton has been brought difficulty.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of middle-size and small-size marine zooplankton depth field imaging monitoring apparatus.This device adopts Structured Illumination, both only provided illumination to the visual field field depth of being observed, avoided the light beam of traditional lighting method to exist in the whole imaging optical path, the scattered beam that is produced owing to the seawater diffuse transmission influence in non-imaging region reduces the contrast of image thus, therefore, improved image quality under water, for the analysis of digital picture provides good foundation.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of middle-size and small-size marine zooplankton depth field imaging monitoring apparatus, and it comprises imaging pressurized capsule body, depth field imaging illumination pressurized capsule body and support frame under water; The built-in light emitting diode of described depth field imaging illumination pressurized capsule body provides illuminating bundle, and described depth field imaging illumination pressurized capsule body is fixed on the support frame; Be provided with object lens, digital camera and Digital Image Data capture card in the described imaging of the imaging under water pressurized capsule body, the cabin body wall of the opposite side of the described imaging of imaging under water pressurized capsule body and described depth field imaging illumination pressurized capsule body is provided with optical window, and the described imaging of imaging under water pressurized capsule body is fixed on the support frame.
Further improved technical scheme, described depth field imaging illumination pressurized capsule body is provided with two, and these two depth field imaging illumination pressurized capsule bodies are relatively positive in support frame,
Further improved technical scheme, described light emitting diode is rectangular arrayed in depth field imaging illumination pressurized capsule body.
Further improved technical scheme, described depth field imaging illumination pressurized capsule body can carry out the position adjustments of longitudinal separation on support frame by moving slider, when moving to the position of expection formulation, by set bolt moving slider is fixed on the support frame, thereby the depth field imaging pressurized capsule body that throws light on is stably fixed on the support frame.
Further improved technical scheme, the described pressurized capsule of imaging under water body is fixed on the support frame by fixed support.
Beneficial effect of the present invention is as follows: the present invention can suppress the scattering effect that non-imaging beam is produced effectively when imaging optical path is propagated, and has greatly improved the image quality of underwater picture, and this reaches to important for the less animal plankton of observation volume; Because the target image resolution of animal plankton is limited, human eye is difficult to carry out the difference of kind to the ambiguous image that swims, thereby brings the differentiation error; By adopting system of the present invention, can improve picture quality, improve the accuracy rate of planktonic organism target-recognition.
