摘　　要：提出了一种基于局部直方图的激光雷达距离像噪声抑制方法。首先分析了成像激光雷达的工作原理以及距离像的噪声模型,在此基础上,给出了一种距离像反常噪声抑制算法。仿真实验表明,该方法具有较好的距离像噪声抑制效果。A laser radar range image suppression algorithm based on local histogram is put forward. The operational principle of image laser radar and the noises model are demonstrated in this paper firstly. Then, an algorithm of range anomalies suppression about noises is advanced. Apply it to the process of actual laser radar range image and get satisfying results.
