Description
Technical field
The present invention relates to seed shrimp field of measuring technique, more particularly, to a kind of detection of seed shrimp bodily form and type selecting equipment and side
Method.
Background technology
In the work of the hereditary and selection of shrimp, the data such as a large amount of frequent bodies for measuring shrimp are long, body is wide is needed to be lost
It passes and learns election effects.Traditional measurement method is that shrimp is artificially stretched extended position, is then measured again with ruler.This method shrimp
There is a great harm for, and the error measured is big, and the consuming time is long and time-consuming and laborious, and working efficiency is low.
To solve the above-mentioned problems, Patent No. 201710291930.0, it is entitled《One seed shrimp measuring system and its measurement
Method》Patent of invention propose one kind and can reduce shrimp injury, and the method that measuring accuracy can be improved.The patent pass through by
Shrimp is put into transparent sink, is shot, and the image of shooting is then uploaded to computer again, and processing identification is carried out using software.
But there are following disadvantages for this method：（1）Shooting is not comprehensive, and then causes the accuracy measured poor；（2）The photo of shooting is easy
It is interfered by ambient, leading to measurement, there are errors；（3）It needs to salvage shrimp repeatedly, the injury that shrimp is subject to is big, and expends
Time is long, and working efficiency is low.
Invention content
The present invention for overcome the deficiencies in the prior art, provides a kind of seed shrimp body improving measurement precision and measurement efficiency
Shape detects and type selecting device and method.
To achieve the goals above, the present invention uses following technical scheme：A kind of detection of the seed shrimp bodily form and type selecting equipment, packet
It includes
Have waterproof, shade function camera bellows；
For the transparent pipeline that seed shrimp water flowing is put into, the transparent pipeline is through in camera bellows, and the both ends of transparent pipeline are pierced by camera bellows
Connection is extraneous；
At least four are uniformly distributed in transparent pipeline periphery, and can acquire the industrial camera of seed shrimp image in transparent pipeline, the work
Industry camera is connected on camera bellows；
The computer of industrial camera is connected, which includes the picture recognition module and data storage mould for connecting industrial camera
Block；
Close to the light source of transparent pipeline in camera bellows；
And the industrial personal computer of connection light source, industrial camera；
