Problems solved by technology

In the process of placing and taking out the feeding table, it is very easy to disturb the prawns and enter the stress state, which will lead to the loss of appetite and slow growth of the prawns.
Knowing the physiological status of prawns is very important for farming, but so far there is no detection method under non-disturbing conditions

Embodiment Construction

[0032] Existing prawn farming is more about observing the appearance indicators such as body length, weight, color and limb condition of prawns. Heart rate is also an important physiological index, but in existing methods, it is often necessary to use sensors or electrodes fixed on the shrimp body. Therefore, the present invention proposes a new solution, providing a non-contact, non-invasive method and system for detecting the heart rate of prawns. For a clearer representation, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] see figure 1 , this embodiment provides a heart rate detection system for prawns based on video images, including: a video acquisition module, an ROI selection module, a signal processing module, and a heart rate calculation module.

[0034] The video acquisition module described in this embodiment is an RGB camera, an infrared camera or a high-definition camera.

[0035] see figure 2 , u...

Abstract

The invention discloses a prawn heart rate detection method and system based on a video image. The prawn heart rate detection method specifically comprises the steps of acquiring a target prawn videoimage through a video acquisition module; identifying a heart region of the prawn in the video image through an ROI selection module and obtaining an original signal sequence; extracting a heart ratesignal from the original signal sequence through a signal processing module; and finally, calculating the heart rate value through a heart rate calculation module. According to the scheme, a sensor oran electrode does not need to be placed on a prawn body, non-contact heart rate measurement can be completed only through a photographing device or a camera, the cost is low, the implementation modeis simple and convenient, and real-time and rapid effects are achieved. The health state of the prawns can be effectively observed, and the prawns cannot generate stress response.

Description

technical field [0001] The invention relates to the technical field of marine prawn breeding evaluation, in particular to a method and system for detecting heart rate of prawns based on video images. Background technique [0002] Prawn is an important marine economic cultured shrimp in my country. It is rich in nutrition and high in economic value, and is deeply loved by the people. my country has a long history of prawn farming and low cost of farming. It has favorable conditions for developing prawn farming in my country and has great potential for developing prawn farming. [0003] However, in the existing culture technology, judging the health status of the prawns is generally done by setting a feeding platform. A certain amount of feed is placed on the feeding table, and after a period of time, the feeding table is picked up to observe the feeding situation of the prawns and the excretion of feces, and observe the individual growth of the prawns obtained by sampling. ...
