基于目标轮廓自动校正的激光反射层析成像投影配准方法

Laser reflective tomography imaging projection registration method based on target contour auto-correction

激光反射层析成像(Laser Reflective Tomography Imaging,LRTI)技术具有分辨率与距离无关的特点,在空间目标遥感中具有广阔的应用前景。在目标图像重构之前,多角度回波投影数据需要与目标旋转中心对齐,这就是投影配准技术。本文提出了一种基于目标轮廓自动校正的投影配准方法,实验结果表明,该方法易于实现对简单目标旋转中心的自配准,能有效减少激光脉冲发射和探测器接收的随机抖动等造成的干扰,解决了图像模糊的问题,是一种LRTI多角度回波配准的新思路。

Laser reflective tomography imaging has a wide application prospect of space target remote sensing because its resolution is independent of distance.Before the reconstruction of the target image,the multi-angle echoes projection data need to be aligned with the rotation center of the target,which is the projection registration technique.This paper proposed a projection registration method based on the target contour auto-correction,and the experimental results show that the method is easy to implement on simple target since the registration center of rotation,can effectively reduce the number of laser pulses launch and detector receive random jitter caused by the interference,such as solved the problem of the fuzzy image,is a kind of LRTI multi-angle echoes registration of new ideas.
