基于扫描相机的激光三维成像研究

随着条纹管器件技术的发展,条纹管作为瞬态光学器件的应用不再局限于高速摄影和光谱学研究领域。建立以单狭缝条纹管为核心器件的扫描相机激光成像系统,对目标进行推扫成像,获得原始条纹图像,并进行特征数据提取和三维重建。理论计算出的两目标的距离差与实际距离差较接近,从而验证采用该系统作激光雷达成像的可行性。实验结果表明,基于扫描相机激光雷达具有高分辨率,具有较好的应用前景。

Research of 3D imaging based on streak tube imaging lidar

With the development of the technology of streak tube device, the application of streak tube as a transient optical device is no longer confined to the field of high speed photography and optical spectroscopy.Streak tube is the core component of imaging lidar and the realization of 3D reconstruction is based on the streak image acquisition and feature data extraction.That the distance difference of the two objects is calculated by the theory is close to the actual distance difference.The feasibility of the system as laser imaging is verified.The experimental results show that the STIL has a high resolution, and has a good application prospect.
