Problems solved by technology

Especially in rural primary and secondary schools, specimens are very important for elementary and middle school students to enlighten their biology. By observing specimens, students can increase their interest in biology and study more attentively. However, because the cost of purchasing specimens is too high and they cannot be stored for a long time, rural The conditions of primary and secondary schools make it impossible to continuously purchase specimens, resulting in outdated versions of specimens

Embodiment 1

[0024] A method for making a living 3D digital specimen, the steps of the method are as follows:

[0025] A. Anesthetize the living body;

[0026] B. Fixing the living body after anesthesia;

[0027] C. Use a handheld 3D laser scanner to scan the living body in step B at 720 degrees in all directions to obtain the 3D point cloud data of the living body in step B, and then use GeomagicStudio software to process the 3D point cloud data to obtain the complete in step B 3D model;

[0028] D, take pictures of the living body in step B by a digital camera;

[0029] E. Laminate the photo in step D as the material with the three-dimensional model in step C on the computer to form a three-dimensional digital specimen whose 3D is consistent with the living body in step B.

[0030] Live anesthesia for aquatic animals by clove oil, an anesthetic in MS222.

[0031] The amount of anesthetic used is adjusted according to the size and adaptability of the subject.

[0032] In step B, a ma...

Embodiment 2

Abstract

The invention discloses a method for making a 3D digital specimen of a living body. The living body is anesthetized and fixed, and then 3D scanned to obtain the 3D point cloud data of the living body, and then the 3D point cloud data is processed by Geomagic Studio software to obtain the 3D point cloud data. The model is photographed by a digital camera, and the photo and the three-dimensional model are synthesized to form a 3D digital specimen. The invention can be applied to various aquatic animals and terrestrial animals, can quickly and comprehensively establish 3D digital specimens of living bodies, and is convenient for teaching and species display.

Description

technical field [0001] The invention relates to a method for making a specimen, in particular to a method for making a living body 3D digital specimen. Background technique [0002] Specimen is the first-hand information of biological science research, the best material for practical teaching, and the best way to perfectly present the appearance of species. For students, specimens are the best way to cultivate observation ability, discover problem ability and acquire new knowledge best tool. Existing specimen preparation methods, especially animal specimen preparation methods, mostly use formalin, phenol, arsenic and other toxic substances for preservation. The complexity of the method, the high technical requirements of the operation process, and the high cost of production all limit the scope of use and practical value of the specimens; and the existing living specimens are presented through two-dimensional images, and cannot be visualized through three-dimensional images...
