Embodiment 1

[0034] A type detection and type selection device for shrimp species, comprising a dark box 1, a transparent pipe 2, four industrial cameras 3, a base 9, an industrial computer 5 and a light source 8. Wherein the camera obscura 1 has waterproof and light-shielding functions. The transparent pipe 2 is made of glass or high-strength acrylic material and is transparent. Transparent pipeline 2 puts in for kind of shrimp through water, and passes through one by one. The transparent pipe 2 runs through the dark box 1, and both ends of the transparent pipe 2 pass through the dark box 1 to communicate with the outside world. In order to facilitate the connection of the transparent pipe 2, joints are provided at both ends of the transparent pipe 2, and a water speed controller is connected to the transparent pipe 2, and the water speed controller is preferably a throttle valve.

[0035] The industrial camera 3 can collect images of shrimps in the transparent pipe 2, and four industri...

Embodiment 2

[0045] The present embodiment is a method for supporting use with implementation 1, a method for body shape detection and type selection for breeding shrimp, comprising the following steps:

[0046] (0) Installation equipment: Open a hole in the middle of the left and right sides of the camera obscura 1, and then place a through transparent pipe 2 in the hole, and the two ends of the transparent pipe 2 penetrate into the camera obscura 1.

[0047] (a) Pretreatment: select live species of shrimp, the tails of the species of shrimp are marked with different fluorescent colors, insert the two ends of the transparent pipe 2 into the immersion tank 10, and connect the two ends of the transparent pipe 2 into the clean water tank 10 with a horn-shaped interface 21, then fill clean seawater in the immersion tank 10, until the water is passed in the transparent pipe 2, the kind of shrimp is from one of the immersion tanks, passes through the transparent pipeline 2 from the trumpet-shape...

Abstract

The invention relates to the technical field of seed shrimp measurement, in particular to a seed shrimp body shape detection and selection device and method. The seed shrimp body shape detection and selection device comprises a dark box with waterproofing and shading functions; a transparent pipeline for supplying water and allowing seed shrimps to pass through, wherein the transparent pipeline runs through the dark box, and both ends of the transparent pipe pass through the dark box to communicate with the outside world; at least four industrial cameras which are evenly distributed around thetransparent pipeline, can collect images of seed shrimps in the transparent pipeline, and are connected to the dark box; a computer connected to the industrial cameras, wherein the computer comprisesan image recognition module connected to the industrial cameras and a data storage module; a light source disposed in the dark box and adjacent to the transparent pipeline; and an industrial controlcomputer connected to the light source and the industrial cameras. The device and method can improve the measurement accuracy, reduce the contact with the seed shrimp, and reduce the damage of the seed shrimp; and the measurement speed is fast and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of shrimp species measurement, in particular to a device and method for body shape detection and type selection of species of shrimp. Background technique [0002] In the work of genetic selection of shrimp, a lot of data such as body length and body width of shrimp need to be measured frequently to carry out genetic selection research. The traditional measurement method is to artificially straighten and stretch the shrimp, and then use a ruler to measure. This method causes great damage to the shrimp, and has large measurement errors, takes a long time, is time-consuming and laborious, and has low work efficiency. [0003] In order to solve the above problems, the invention patent with the patent number 201710291930.0 and titled "A Shrimp Measurement System and Its Measurement Method" proposes a method that can reduce shrimp damage and improve measurement accuracy. In this patent, shrimps are put into a t...
