Embodiment Construction

[0034] In order to describe the technical solution disclosed in the present invention in detail, further elaboration will be made below in conjunction with the accompanying drawings and specific embodiments.

[0035] In terms of industrial manufacturing, bionics is an important technology for research and application. What the present invention provides is a method for modeling the contour of micron puffer puffer epidermis body spines based on image processing.

[0036] The first is the sample extraction process: take adult healthy pufferfish (pufferfish) as the experimental object, peel off the complete fish skin and soak it overnight until the mucus is separated from the epidermis, clean it, and use biological dissection tools to dissect and mark the pufferfish epidermis. Soak the epidermis with 5% potassium hydroxide solution, and place it in a KH-45A incubator for 6-8 hours to accelerate the dissolution of the fish skin. After the fish skin is dissolved, pour out the turb...

Abstract

The invention discloses a micron-sized puffer fish epidermal spine contour modeling method based on image processing, and the method comprises the steps: firstly obtaining a microscopic image of a target sample located in the same focal plane through a microscopic technology, and then obtaining the complete contour of a sample image; obtaining a CAD file of the contour image by means of software;reconstructing a coordinate system through CAD software and obtaining contour spline points in batches; finally, achieving fitting of contour curve spline points in MATLAB, obtaining a high-precisionsample contour curve mathematical expression, and therefore establishing a three-dimensional model. According to the method, the mathematical model of the outline of the micro sample piece can be obtained only through computer software, operation is easy and economical, meanwhile, local characteristic parameters can be extracted according to results, the modeling efficiency and quality are improved, and the problem that in the prior art, the modeling precision of the micro sample piece is low is solved.

Description

technical field [0001] The invention belongs to biological modeling technology, and in particular relates to an image processing-based method for modeling the contour of micron-scale fugu epidermis body thorns. Background technique [0002] In bionics, it is usually necessary to extract the microstructure of the biological surface for feature analysis in order to establish a drag reduction element model and apply it to the surfaces of aircraft, ships, swimsuits, etc. to achieve the effect of drag reduction. In the past, due to the difficulty of modeling due to the small size of the sample, the morphological outline was simplified, ignoring many structural features, and the model accuracy was low. Therefore, the modeling of micron-scale structures lacks a modeling method that is simple to operate, economical, and capable of obtaining contour features with high precision.
