摘　　要：目前,三维激光扫描仪已经广泛应用于三维建模、变形分析等领域。其中,点云数据的平滑滤波是点云预处理的核心问题,制约着三维激光扫描仪的应用。本文通过对双边滤波原理进行分析,将其应用到点云数据的平滑滤波过程中。通过实验数据验证,双边滤波可以有效地降低点云数据的噪声水平,具有广泛的应用价值。At present, three dimensional laser scanner has been widely used in three dimensional modeling, deformation analysis, deformation analysis, and other fields. Among them, the point cloud data smoothing filtering is the core of the point cloud pretreatment, restricts the application of three dimensional laser scanners. In this article, through analysis of bilateral filtering algorithm and apply it to the point cloud data in the process of smoothing fiher. Validated by the experimental data, the bilateral filter can effectively reduce the level of noise in point cloud data and can be used widely.
