This paper introduced mode of collecting, technology of filtering and measuring process about image of three dimension composite preform surface.
首先介绍了三维编织复合材料预制件表面图象的采集方式、滤波技术以及平均编织角的测试过程;

The feasibility and effective of the multi-radial mid-value filtering have been verified through some model data tests and suppressing the surface wave in the practical pre-stack seismic data.
The discal filer realized the combination of surfacefiltering and depth filtering. The automatic switching over of filtering and cleaning process is realized.
