提出了一种利用激光照明距离选通观察实现远距离三维成像的方法。三维场景重建的基础是使用滑动门延迟时间获取的图像序列。提出了两种不同的方法，并通过Monte Carlo模拟使用简化的系统和成像模型的算法性能进行了研究。通过与0.8至7.2公里范围内的真实的测量值进行比较，证明了假设的合理性。结果表明，距离分辨率和精度成为显着优于系统设计参数，如门的长度，门过渡长度，门步长。因此，所提出的重建方法能够使用可用的远程选通成像系统进行高精度距离成像。(c)2006年，由光学仪器工程师协会（Society of Photo-Optical Instrumentation Engineers）主办。
An approach to long-range 3-D imaging using laser illuminated range-gated viewing is presented. The basis for 3-D scene reconstruction is an image sequence acquired using a sliding gate delay time. Two different methods are suggested, and algorithm performance is investigated through Monte Carlo simulations using a simplified system and imaging model. Assumptions are justified by comparison with real measurements at range of 0.8 to 7.2 km. It is shown that range resolution and precision become significantly better than system design parameters such as gate length, gate transition length, and gate step length. The presented reconstruction methods thus enable high-precision range imaging using available long-range gated imaging systems. (c) 2006 Society of Photo-Optical Instrumentation Engineers.
