Problems solved by technology

[0003] The traditional measurement method has the following disadvantages: 1. The prawns are easily frightened and jump after leaving the water. The operator is easy to cause damage to the prawns in the process of holding the prawns, and some weak prawns are easily damaged after leaving the water. It is easy to die from hypoxia; 2. The error of human measurement is difficult to control, and the measurement results vary greatly due to the subjective judgment of each person; 3. The measurement work requires the cooperation of at least 2 people to complete, and the data needs to be carried out after the measurement is completed. computer entry jobs
The measurement method in this patent has the following defects: This method can only measure shrimps that have lost their vital signs or are anesthetized. If live shrimps are measured in a state out of water, the damage to the shrimps after leaving the water is greater, and the live shrimps after leaving the water It will bounce, it is difficult to take pictures and measure

Embodiment 1

[0041] refer to figure 1 and 2 As shown, a kind of prawn measuring system is disclosed in the present embodiment, its main structure includes: console 1, camera 2 is arranged on above-mentioned console 1, above-mentioned camera 2 is connected with computer 4 signal, in this embodiment, above-mentioned The camera 2 is connected to the computer 4 through a data line 5 , and the image data acquired by the camera 2 is transmitted to the computer 4 .

[0042] A transparent water tank 3 is also provided on the above-mentioned operating table 1, and the above-mentioned transparent water tank 3 is detachably fixed on the above-mentioned operating table 1.

[0043] The above-mentioned camera 2 is fixed on the above-mentioned console 1 through a fixed bracket 201, and the distance between the above-mentioned fixed bracket 201 and the above-mentioned transparent water tank 3 is fixed. In this example, if figure 2 As shown in , the bottom of the above-mentioned transparent water tank ...

Embodiment 2

[0050] The difference between embodiment 2 and embodiment 1 lies in the fixing method between the transparent water tank and the operating table, such as image 3 As shown: the bottom of the above-mentioned transparent water tank 3 is provided with an engaging part 301, and the position where the above-mentioned operating table 1 is placed on the above-mentioned transparent water tank 3 is provided with a raised rib 303, and the end surface of the above-mentioned engaging part 301 is provided with a card groove 302. The engaging groove 302 cooperates with the above-mentioned protruding rib 303 .

[0051] The size of the glass water tank 3 should match the size of the shrimp to be measured. For example, if the body length of the shrimp to be measured is within the range of 10.00±1.00cm, then the required length of the water tank should be 13cm; the width of the tank should be slightly larger than that of the shrimp to be measured. body width.

[0052] The transparent water tan...

Embodiment 3

[0054] Disclosed in this embodiment is a measurement method based on the system of embodiment 1 and embodiment 2, the method comprising:

[0055] The following steps:

[0056] S101 Use a net to fish the prawns to be tested into the first transparent water tank filled with water, the water in the transparent water tank just submerges the prawn body, and fix the transparent water tank on the operating table;

[0057] S102 controls the camera through the computer to aim at the first transparent water tank to take pictures;

[0058] S103 Fill the second transparent water tank with the same amount of water as the first transparent water tank, fish the prawns into the second transparent water tank, and fix the transparent water tank on the operating table;

[0059] S104 controls the camera to aim at the second transparent water tank to take pictures, and circulates successively until all the prawns to be tested are photographed;

[0060] S105 The photos taken by the above-mentione...

Abstract

A penaeus orientalis measurement system disclosed by the present invention comprises an operating bench, a camera is arranged on the operating bench and is in signal connection with a computer, and the image data obtained by the camera is transmitted to the computer. The operating bench is also equipped with a transparent water tank, the transparent water tank is fixed on the operating bench detachably, and a measurement software is loaded in the computer and comprises a data reception module for receiving the image information transmitted by the camera; a manual module used for manually intercepting the information of the sites in a shot picture; a data processing module used for calculating the distances between the sites intercepted by the manual module and obtaining the penaeus orientalis measurement data; and a data storage module used for storing the data processed by the data processing module. The penaeus orientalis measurement system and the measurement method thereof can reduce the damage of the artificial measurement to the shrimps furthest, are high in measurement precision, and can avoid the errors caused by the artificial measurement.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a prawn measuring system and a measuring method thereof. Background technique [0002] In the genetic selection and breeding of prawns, a large number of frequent measurements of the body length and body width of the prawn broodstock or cultured shrimp are required for genetic selection and breeding research. The traditional measurement method is to pick up the shrimp from the water with a net. The operator holds the shrimp in one hand, stretches the shrimp body as straight as possible, and holds a ruler or a vernier caliper in the other hand to measure the data such as the length of the shrimp body segment. The measurement data needs to be recorded by another operator with a notebook. After the measurement work is completed, the measured data needs to be manually input into the computer. [0003] The traditional measurement method has the following disadvantages: 1. The pra...
