摘要
高斯滤波器因其构造、设计简单,且滤波特性具有零相移特性,目前已经是ISO 11562和ASME B46.1规定的基准提取方法,但由于其支撑域范围过大,一定程度影响到其在三维基准提取中效率[1]。为此,结合相关专利与文献,引入巴特沃思函数构建基于并行算法的高斯滤波算法,以提高其在实际工程应用中的效率。并将其运用到三维实例中,从中可以发现基于并行的算法所耗时间低于其他算法。
Due to the convenience in design and zero phase- shift, the Gaussian Filter has been adopted in ISO11562 and ASME B46.1 as a standard reference representation method. However, it always has bad performance andlow efficiency in 3-D reference representation.Therefore,make use of the parallel Butterworth Filter to realized thetraditional Gaussian Filter and increase its efficiency in reference representation based on related patents and theses.
