Description
Technical field
The present invention relates to shrimp field of measuring technique living, more particularly, to a kind of living body prawn growth phenotype detection device and side
Method.
Background technique
In the work of the hereditary and selection of prawn, need the data such as the bodies of a large amount of frequent measurement prawns are long, body is wide come into
Row science of heredity election effects.Traditional measurement method is that extended position artificially is straightened in shrimp, is then measured again with ruler.The party
There is a great harm for method prawn, and the error measured is big, and 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《A kind of prawn measuring system and its survey
Amount method》Patent of invention propose one kind and can reduce prawn injury, and the method that measuring accuracy can be improved.The patent is logical
It crosses and prawn is put into transparent sink, shot, the image of shooting is then uploaded to computer again, handled using software
Identification.But there are following disadvantages for this method：（1）Shooting is not comprehensive, and then causes the accuracy of measurement poor；（2）The photograph of shooting
Piece is easy the interference by ambient, and leading to measurement, there are errors；（3）Need to salvage prawn, the injury that prawn is subject to repeatedly
Greatly, and consuming time is long, and working efficiency is low.
Summary of the invention
The present invention for overcome the deficiencies in the prior art, provides a kind of living body pair for improving measurement precision and measurement efficiency
Shrimp growth phenotype detection device and method.
