基于光投影数字化传感系统的飞蝗表面三维结构

The three dimensional structure of the migratory locusts’s exoskeleton as revealed by a light projection digital sensing system

本文基于结构光投影数字化传感系统构建东亚飞蝗Locusta migratoria manilensis表面的三维结构。首先得到其外形尺寸和肢体各部分拓扑结构,然后从被调制的条纹结构光中恢复出物体表面高度变化的相位信息,再通过相位和高度的对应关系重建出物体表面三维特征。此结果将为农药研制和施用设计提供科学依据,对促进蝗虫的防治以及虚拟昆虫研究起到积极作用。

The three dimensional structure of the Locusta migratoria manilensis exoskeleton was constructed using a light projection digital sensing system. We first obtained data on the shape dimensions and topological structure of body parts of individual locusts. We then recovered highly variable phase information on the objective surface of each structure from a modulated strip of light. The corresponding relationship between light phase and height allowed three-dimensional surface features to be reconstructed. The results will be valuable for pesticide design and locust control.
