Embodiment 1

[0021] A method for investigating aquatic animal density, comprising the following steps:

[0022] S1, divide the water area to be measured into regions;

[0023] S2, use a 360-degree diving camera to dive into the water in the middle of each area to take pictures;

[0024] S3, use the image recognition system to identify the fish species to be investigated and count the number of fish species in each area;

[0025] S4. Steps S1-S3 are repeated until the calculated value tends to be stable.

[0026] During implementation, in step S1, the area division of the water area to be measured is a circular area with a radius of the camera's underwater visibility distance value, and the 360-degree diving camera includes five independent cameras, and the angles of view of the five independent cameras are horizontal Cameras facing east, south, west, and north and cameras with a downward viewing angle; the five independent cameras are all waterproof cameras, and the five independent came...

Abstract

The invention discloses an aquatic animal density survey method. The method comprises the following steps of S1, performing area division on a to-be-tested water area; S2, performing photographing inwater by using a 360-degree diving camera in each area; S3, identifying to-be-surveyed fingerlings by using an image recognition system and performing statistics on the quantity of the fingerlings ineach area; and S4, repeating the steps S1 to S3, until the obtained quantity value tends to be stable. The 360-degree diving camera is used for photographing organisms in the water of the water area;the image recognition technology is used for carrying out image recognition analysis on the to-be-surveyed fingerlings; the quantity of the corresponding fingerlings is obtained; the density of the fingerlings can be obtained according to the size of the water area; when underwater photos are obtained, a plurality of 360-degree diving cameras can be used simultaneously for performing image collection on all areas, so that the effect of inaccurate quantity statistics caused by biological motion can be avoided; and the surveyed organisms are subjected to total quantity statistics through image recognition, so that a statistical result is high in accuracy.

Description

technical field [0001] The invention relates to a method for investigating animal density, in particular to a method for investigating aquatic animal density. Background technique [0002] The density survey of aquatic organisms is helpful to the research on the population of aquatic organisms, and the population density can be adjusted reasonably, which can maximize the use of breeding space and increase the production of breeding. The common fish species density investigation method uses traditional random area fishing, or Visual inspection is used to calculate the density of fish species. This method has too much error to obtain accurate species density. Contents of the invention [0003] The technical problem to be solved by the present invention is: the ordinary fish species density survey method uses traditional random area fishing, or visual inspection to calculate the fish species density, the error of this method is too large, and it is impossible to obtain accura...
