A bird pecking motion research method based on a body section model

Abstract

The invention relates to a bird pecking motion research method based on a body segment model, and the method comprises the steps: employing a camera to shoot a bird single pecking motion video, carrying out the editing and framing of the video, and obtaining a plurality of continuous pecking motion image sequences; Establishing a bird body section model according to the movement link in the bird pecking movement; Extracting bird body outer contours and feature points in the pecking motion image sequence, matching the bird body section model with an area occupied by birds in the image sequenceto obtain shape and size data, establishing a three-dimensional model of the body section model, performing assembly to obtain a three-dimensional model of the whole bird, and performing simulation toobtain a motion track of the beak tip. The method solves the problem that the motion error of feature points on bird feathers directly captured is large, accurate and comprehensive pecking motion data are obtained, pecking motion data are obtained through three-dimensional modeling and simulation, quantitative research on bird pecking motion under the unmarked condition and the non-contact condition is achieved, and a new idea for motion research is provided.

Description

technical field [0001] The invention relates to the field of bionics, in particular to a research method for bird pecking movement based on a body segment model. Background technique [0002] Because of the unique beak structure, birds usually eat, destroy and attack by pecking their beaks, such as woodpeckers, chickens, and cranes. The most typical one is the woodpecker, which eats or builds nests by pecking trees. Woodpeckers peck trees at a high frequency, and the impact acceleration reaches about 1000g, and woodpeckers can avoid brain damage during the impact. Therefore, the uniqueness of woodpeckers' pecking behavior has important engineering significance in terms of structure, materials and mechanics, and the study of woodpeckers' pecking movement is an important part of exploring woodpeckers' pecking behavior. [0003] Existing research on woodpecker pecking movement is less, mainly divided into two categories, the first is to use high-speed cameras to capture the mo...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a body segment model-based research method for bird pecking movement, which solves the problem of large pecking movement data errors caused by directly capturing the feature points on the bird feathers because the whole body of the bird is covered by feathers. big problem
