摘要
针对激光雷达一维距离像的目标识别 ,提出了利用最小二乘估计器和线性滑动更新器构造滤波器的算法 .并根据目标本身形态的总体尺度范围特征 ,设定滤波窗口 ,很好地实现了对目标的识别过程 .利用该算法 ,在信噪比为 1.6 :1时 ,目标识别的正确率达到 86 % .
A new arithmetic approach to the target identification of lidar range image was introduced by using the least squares estimation and linear glide updater for the design of a filter. The filter window was set up in accordance to the characteristics of target shape size. This arithmetic approach can have an easy access to the process of target identification. By means of this arithmetic, correct rate of target identification can reach approximately 86% under the condition that the SNR is 1.6∶1.
