Embodiment 1

[0032] A living prawn growth phenotype detection device, 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. The transparent pipe 2 is used for putting the prawns to be tested through water, and passing through them 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.

[0033] Described industrial camera 3 can gather the prawn image in transparent pipe 2, and four...

Embodiment 2

[0041] This embodiment is a method used in conjunction with implementation 1, a method for detecting the growth phenotype of living prawns, comprising the following steps:

[0042] (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 pass through the hole of the camera obscura 1.

[0043] (a) Pretreatment: Select live prawns. The tails of the prawns are marked with different fluorescent colors. Connect the two ends of the transparent pipe 2 to the water immersion tank, and then fill the water immersion tank with clean seawater until the transparent pipe 2 is filled with water, and the prawns from it A immersion tank passes through the transparent pipe 2 one by one, and then enters another immersion tank.

[0044] (b) Image collection: The industrial camera collects images of at least four sides of the prawns, and then transmi...

Abstract

The invention relates to the technical field of living prawn measurement, and particularly discloses living prawn growth phenotype detection equipment and method. The equipment comprises a dark box, atransparent pipeline, industrial cameras, a computer, a light source and an industrial personal computer, wherein the dark box is provided with a waterproof function and a light shielding function; the transparent pipeline is used for placing to-be-detected prawns into water, the transparent pipeline penetrates through the dark box, and the two ends of the transparent pipeline penetrate out of the dark box and communicate with the outside; at least four industrial cameras are uniformly distributed on the periphery of the transparent pipeline and can be used for collecting prawn images in thetransparent pipeline, and the industrial cameras are connected to the dark box; the computer is connected to the industrial cameras, and the computer comprises an image recognition module and a data storage module which are connected to the industrial cameras; the light source is arranged in the dark box and is close to the transparent pipeline; and the industrial personal computer is connected tothe light source and the industrial cameras. According to the equipment and the method, the measurement accuracy can be improved, and the contact with the prawns can be reduced, so that the damage tothe prawns is reduced; and furthermore, the measuring speed is fast, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of live shrimp measurement, in particular to a living shrimp growth phenotype detection device and method. Background technique [0002] In the work of genetic selection and breeding of prawns, a large number of data such as body length and body width of prawns need to be measured frequently for genetic selection and breeding research. The traditional measurement method is to artificially straighten and stretch the shrimp, and then use a ruler to measure. This method does great harm 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 patent No. 201710291930.0 and the invention patent titled "A Measuring System and Method for Prawns" propose a method that can reduce the damage to prawns and improve the measurement accuracy. This patent puts prawns into a transparent tank, takes pi...
