| 摘 要： | 针对利用最近点迭代（ICP）算法进行点云数据配准时费时较多的问题,提出结合Butterworth高通滤波器和Sobel边缘检测算子首先对点云数据进行预处理,然后再用ICP算法进行点云配准,有效解决这一问题,加快配准速度,并在Matlab中编程实现该方法,具体实验结果证明该方法的有效性。

| Abstract: | Too much time will be taken to match the points cloud with traditional ICP algorithm.The paper presents a new method to solve this problem.The Butterworth High-pass filter and Sobel edge detection operator are combined to preprocess the data firstly,and then match the points cloud with ICP algorithm.In this way,the registration is accelerated,and it was programmed with MATLAB.Finally,the experiment results show the validity of this method. |
