摘要 利用数字化三维立体扫描和构图技术,研究了5种检疫性昆虫标本的3D模型打印方法。以5种昆虫三维数字模型为基础,通过比较模型与昆虫实物的整体以及细微结构特征的拟合度,筛选优化出昆虫3D 打印最佳方案和最优着色方法。结果表明应用光敏树脂3D 打印技术打印的标本模型与标本实体细节特征拟合度较高,并在此基础上研究得出了适用于昆虫的最佳打印流程,该打印方法具有易学、简便、高效、仿真度高等优点,为研究昆虫高仿度非实物标本的制作工艺提供了有益的探索。

Abstract The 3D model printing method of insect specimens was studied by using digital 3D scanning and 3D composition technology. Based on the 3D digital models of 5 kinds of insects, the best 3D printing scheme and the best coloring method of insects were selected and optimized by comparing the degree of fitting between the models and insects as well as the fine structural features. The results showed that the specimen model printed by the photosensitive resin 3D printing technology had a higher degree of fitting with the specimen physical feature. On this basis,the best printing method for insects was gotten. The printing method had the advantages of being easy to learn, simple, efficient, and high in simulation. It provided a useful exploration for the study of the production process of insect highsimulation physical specimens.

昆虫是动物界最大的一个类群,全世界已知100多万种。而昆虫标本则是确定昆虫种类的重要依据,也可作为植物检疫、科研、教学、害虫防治、益虫利用以及科技知识普及宣传的重要参考。形态学鉴定是昆虫物种鉴定的一种传统检测方法,也是进出境检疫机构最主要的技术执法手段。标本是昆虫物种鉴定中不可或缺的重要参考标准,然而要想得到大量完整而珍贵的标本,必须先通过口岸截获或者监测采集直接获得原始虫体,再通过标本制作形成最终的标本,一个成品标本需要花费大量的时间和精力,且由于昆虫标本以及制作工艺的先天缺陷,实物标……
