Problems solved by technology

[0003] The traditional fish phenotype extraction technology is based on contact, either by manual measurement and other methods to obtain the specific morphological parameters of the fish, or by taking pictures of the front and then extracting the phenotype by image processing methods. This process is inefficient and will Harmful to fish, and not suitable for large-scale extraction of fish phenotypic parameters

Embodiment Construction

[0058] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0059] like figure 1 As shown, the non-contact fish morphological phenotype automatic acquisition device of the present invention includes a CCD sensor assembly, a shooting bracket 4, and an image processing device 5;

[0060] The shooting bracket 4 forms a cuboid space;

[0061] The CCD sensor assembly includes a first CCD sensor 1, a second CCD sensor 2, and a third CCD sensor 3;

[0062] The first CCD sensor 1, the second CCD sensor 2, and the third CCD sensor 3 are respectively arranged directly in front of, directly above, and directly to the left of the cube space;

[0063] The output ends of the first CCD sensor 1 , the second CCD sensor 2 , and the third CCD sensor 3 are all electrically connected to the input end of the image processing device 5 .

[0064] Wherein, the first CCD sensor 1, the second CCD sensor 2, and the third CCD s...

Abstract

The invention relates to the technical field of fish phenotype extraction, and provides a non-contact automatic fish morphotype acquisition device and method. The device includes a CCD sensor assembly, a shooting bracket and an image processing device. The method includes: step 1: work preparation; step 2: using a CCD sensor component to obtain three views; using an image processing device to perform steps 3 to 9: step 3: judging whether the three views meet the requirements for phenotype extraction; step 4: obtaining according to the top view Fish orientation parameters and width parameters; Step 5: Select the main image for phenotype extraction from the main view and left view; Step 6: Obtain the main color range of the main image; Step 7: Extract the boundingbox of each part of the fish; Step 8: Extract the feature points of each part; Step 9: Calculate the global phenotypic parameters according to the feature points. The invention can automatically, quickly and accurately obtain the global morphological parameters of the fish without contact, without causing any harm to the fish.

Description

technical field [0001] The invention relates to the technical field of fish phenotype extraction, in particular to a non-contact automatic fish morphotype acquisition device and method. Background technique [0002] Fish phenotypes are artificially defined fish characteristics. By digitizing these characteristics, people can perform various statistical analyzes on fish, which is very helpful for specific research such as fish breeding and classification. [0003] The traditional fish phenotype extraction technology is based on contact, either by manual measurement and other methods to obtain the specific morphological parameters of the fish, or by taking pictures of the front and then extracting the phenotype by image processing methods. This process is inefficient and will Harmful to fish, and not suitable for large-scale extraction of fish phenotypic parameters. Contents of the invention [0004] Aiming at the problems existing in the prior art, the present invention pr...
