摘要
瞄准战时对地面场景快速、被动三维测量的需求和难点,研究基于目标偏光的单视角对地三维重建技术,提出一种低成本、超轻小型偏振立体成像系统。该系统易于在无人机等平台搭载,并且单视角被动拍摄即可实现场景三维重构,作用效率高,能够实现秒级条件下的三维重建,重建精度优于2倍空间分辨率。此外,该技术被动、单视角的探测优势,使其在地形导航、对地侦察测绘、舰船尾迹搜寻等陆海空装备领域具有广泛的应用前景。
The demands and complexities of a rapid passive 3D measurement of ground scenes during wartime have been addressed by developing a single-viewpoint target-polarisation-based 3D optical reconstruction technology.This system is easily deployable on platforms such as unmanned aerial vehicles,enabling 3D scene reconstruction with a single passive viewpoint.Owing to this design,the system exhibits a high efficiency,capable of achieving 3D reconstruction under subsecond conditions with its accuracy surpassing twice its spatial resolution.Additionally,the passive single-viewpoint detection advantages of this technology enable extensive applications in areas such as terrain navigation,reconnaissance mapping,and ship wake detection,spanning across diverse domains of land,sea,air,and space equipment.
