Behavior parameter determination method for moving animals

Abstract

The invention belongs to the technical field of animal behavioristics, and particularly relates to a method for measuring behavior parameters of a moving animal. Comprising the following steps: step 1, continuously shooting a moving animal to obtain position pictures of the moving animal at different time points; 2, generating a delay image according to the obtained position pictures of the moving animal at different time points, and drawing a movement track of the moving animal; 3, obtaining the movement speed of the moving animal in the delay image according to the movement track; 4, actual motion parameters of the moving animal in the motion container are obtained according to the proportion of the delay image time and the continuous shooting time of the moving animal, and a method for calculating the actual motion parameters of the moving animal in the motion container in the step 4 comprises the steps that a delay coefficient between the delay image and the actual animal motion image is obtained, and the actual motion parameters of the moving animal in the motion container are obtained; and on the basis of the delay image, acquiring the movement speed of the animal in the delay image, and calculating the product of the delay coefficient and the conveying speed in the delay image, namely the actual operation speed of the animal.

Description

technical field [0001] The invention belongs to the technical field of animal behavior, in particular to a method for measuring behavioral parameters of moving animals. Background technique [0002] Animal behavior patterns are an important branch of zoology research, and animal behavior is closely related to important life activities such as feeding and avoiding predators. Animal behavior in nature presents a variety of forms, with complex and changeable characteristics. Model animals that are widely concerned, such as mice and zebrafish, have medium or fast movement speeds. However, there are many kinds and wide distributions of low-speed animals in nature, such as snails, seahorses, starfish, sea cucumbers, and sloths. They occupy different ecological niches in the ecosystem and play an important role in maintaining the ecological environment and maintaining the balance of biological communities. The behavioral parameters of low-speed moving animals have the characteri...

Problems solved by technology

Due to the irregular movement direction of animals, the movement trajectory is often repeated, and the calculation method that only considers the starting point and the end point will lead to large deviations in the research results; the movement state is intermittent, and the measurement of the average speed leads to unclear understanding of the movement law in a specific period of time

The movement trajectories of animals mostly present curves, and the action patterns are mostly trial and error, especially when observing aquatic animals, the three-dimensional movement patterns in the water body cause serious deviations in the observed values, so the reliability of this method is poor

Some benthic aquatic animals move slowly and take a long time to observe. It is not feasible and reliable to rely on experimenters to observe
