Problems solved by technology

The markers in the prior art are often stuck on the back of the fish body, and the method of manual labeling is usually used. Manual labeling of fish vaccines has certain technical requirements, and it needs to be trained to work on the job. The conditions are strict and the labor intensity is high. The speed is slow, continuous high-intensity work cannot be performed, and manual operation has a great impact on the fish itself. A large number of fish died on the day of the vaccine.
[0003] At present, in foreign fish marking research, both manual marking and mechanical equipment marking are used, but the price of foreign automatic fish marking equipment is extremely high, and each set of equipment only It can target a single type of fish, but it is not suitable for biomarkers of different types of fish. More importantly, there are technical barriers to foreign equipment, which makes it difficult to introduce it or use its technology for fish biomarker research in my country

Embodiment 1

[0037] See attached Figure 1-9 As shown, the automatic tagging machine includes: a tagging box 70, the tagging box 70 is supported by the supporting frame body 30 and the supporting frame body 30 is provided inside, and the inside of the tagging box body 70 is also installed with a frame for moving the fish body along the horizontal The transmission assembly 20 for linear transmission, the two sides of the transmission assembly 20 are equipped with a limit mechanism 90 for limiting the position of the fish body through the support frame body 30;

[0038] The visual detection assembly 40 is located above the transmission assembly 20 and is fixedly connected with the support frame body 30 through the connecting frame body. The visual detection assembly 40 is located above the limit mechanism 90 and is adjacent to the limit mechanism 90. The limit mechanism 90 is close to the input end of the transmission component 20,

[0039] The manipulator 50 is arranged in the labeling box...

Embodiment 2

[0051] See attached Figure 10 As shown, an automatic labeling method using an automatic labeling machine, the steps are as follows:

[0052] -The visual detection component 40 collects images of the tagged fish and transmits them to the control unit, and the control unit locates and extracts the outline of the fish in the image, excludes the target area that is not the outline of the fish, and generates a coordinate system;

[0053] -The control unit sets the tagging area to occupy more than 1 / 2 of the back of the fish or the middle of the belly of the fish;

[0054] - The control unit determines the tangent line tangent to the back or abdomen of the fish according to the acquired image, and determines the perpendicular line of the tangent line as the marking point, and the marking point is located on the fish body;

[0055] - Control the fixed-point tagging operation of the manipulator according to the position of the coordinate system of the tagging point;

[0056] In the...

Embodiment 3

[0059] This embodiment further discloses the auxiliary calculation formula adopted by the control unit in the embodiment 2 for locating and extracting the fish contour in the image, specifically the following calculation formula:

[0060]

[0061] In the formula, K is the correction parameter (0.1<K is less than 0.2); xi is the coordinate point of the horizontal axis; yi is the coordinate point of the vertical axis; n is the area of ​​the recognition image; i is the area of ​​the fish outline.

[0062] In the present invention, by setting the tagging limit point under the conveyor belt of the fish body tagging area and setting a light-emitting device, this area is set as the image search target area, and the black area in the area is searched, and the fish body is illuminated by the light-emitting device. The image obtained at the position of the fish body is a black area, and the outline shape of the fish body can be quickly identified. The binarization threshold in the ima...

Abstract

The invention discloses an automatic label hanging machine and a label hanging method, and belongs to the field of biological labeling. The automatic label hanging machine comprises a label hanging box body, a visual detection assembly and a manipulator, wherein a conveying assembly used for conveying fish bodies along a horizontal straight line is further installed in the label hanging box body, and limiting mechanisms used for limiting label hanging of the fish bodies are installed on the two sides of the conveying assembly through supporting frame bodies; and the manipulator is arranged in the label hanging box body and located above the conveying assembly, and the manipulator is controlled by a control unit to hang labels on the fish bodies at set positions. According to the invention, automatic, rapid and accurate positioning and label hanging of the fish bodies are realized, the stress response of manual fishing and label hanging to the fish bodies and the relative randomness of the label hanging position are reduced, the label hanging efficiency is greatly improved, a technical support is provided for evaluation of large-scale artificial proliferation and release effects, and an important technical means is also provided for investigation and protection of fishery materials.

Description

technical field [0001] The invention belongs to the technical field of biomarkers, and in particular relates to an automatic labeling machine and a labeling method. Background technique [0002] A method of studying fish migration and fish stocks. Mark the fish caught in natural waters and put them back into the original waters. When they are recaptured, they can be used to study the migration, distribution, growth and resources of fish. In 1886, Petersen et al. used the method of marking fish to estimate the size and mortality of fish populations in closed water bodies, and the tagged releasing technology was developed. The markers in the prior art are often stuck on the back of the fish body, and the method of manual labeling is usually used. Manual labeling of fish vaccines has certain technical requirements, and it needs to be trained to work on the job. The conditions are strict and the labor intensity is high. The speed is slow, continuous high-intensity work cannot ...
