| 摘 要： | 利用激光三维扫描系统测量了黄蜻膜翅样品的几何外形,获取了黄蜻膜翅几何表面的外形数据点群.利用逆向工程软件对黄蜻膜翅点群数据删除跳点、坏点及与研究无关的数据点并进行平滑和精简处理.根据黄蜻膜翅的外形特征,通过框选点群命令,从点群数据中提取其边界曲线,并对曲线进行调整,将调整好的边界曲线两两拼接在一起,形成黄蜻膜翅较完整的边界曲线.采用由点和曲线形成曲面中的混合点群加边界曲线的造型方法,成功进行了黄蜻膜翅外形三维几何曲面模型的重构.

| Abstract: | The digital point groups of geometrical surfaces of dragonfly Pantala flavescens Fabricius membranous wings were obtained through measuring with a 3D scanner.Using reverse engineering software,imageware,the scanning data point groups of the dragonfly wing were processed,including of deleting error points,smoothing the scanning data by Gaussian filter and reducing the data by chordal deviation method.Based on the shape features of the dragonfly wing,the boundary curves were picked up by circle-select points ... |
