激光三维成像技术及其主要应用

阐述了目前三维成像在其常见应用领域中的研究,主要致力于研究高分辨率三维成像系统。三维激光成像是一项可以应用于探测隐藏目标、地形测绘、构建虚拟环境、城市建模、目标识别等领域中的技术。在区域成像技术中,除了如立体视觉和结构化灯光等更常规的技术,实时三维传感也具有现实可操作性。当前三维激光成像技术已经发展到有能力提供厘米级波长的高分辨率三维成像,这将给许多领域提供方便,包括法律的实施和法医调查。与CCD和红外技术等传统的被动成像系统相比,激光成像技术不仅能提供强度和范围信息,还能穿透植被和窗户等特定情景元素。这意味着激光三维成像系统在目标识别与辨认等方面具备新的潜力。结果表明,激光三维成像系统可以在许多情况下得到应用。

3-D laser imaging technology and applications

The ongoing research on 3-dimensional(3-D) imaging is described.Specifically,address the new possibilities brought by laser imaging,focusing on systems for high resolution 3-D imaging.Real time 3-D sensing is a reality and can,besides more conventional techniques such as stereo vision and structured light,be achieved by range imaging.Current development of 3-D sensing flash laser imaging systems will provide the capability of high resolution 3-D imaging at long ranges with cm-resolution at full video rate.In all probability,this will revolutionize many applications,including law enforcement and forensic investigations.In contrast to conventional passive imaging systems,such as CCD and infrared(IR) techniques,laser imaging provides both intensity and range information and has the ability to penetrate certain scene elements such as vegetation and windows.This,in turn,means new potentials,for example,in object recognition and identification and we address some of these new capabilities of 3-D laser imaging systems.The results clearly show that 3-D imaging laser imaging systems are useful in a variety of situations that can be used to enable technologies for preventing.
