Experimental Validations of Insect 3D Orientation Extraction based on Cooperative Observation from two Views of Entomological Radars

Individual trajectories are central to the study of insect migration. To realize fine-grained descriptions of migration, all information relevant to individual trajectories should be considered, especially the three-dimension (3D) orientation. The aim of this study is to demonstrate that insect 3D orientation can be effectively estimated by cooperative observation from two views of entomological radars. First, the 3D orientation extraction method based on dual radars is reviewed. This method shows that 3D orientation can be estimated by 2D orientations from two views of entomological radars. Then, three individual insects brought to the air by unmanned aerial vehicles are measured to prove the effectiveness of insect 3D orientation extraction.
