在当前地磁数据噪声预处理过程中，存在效率低下、处理质量因人而异的缺点，借鉴数学形态学的去噪方法，基于C/C++编程语言和Qt开发框架，设计开发一套地磁数据噪声处理软件，提高地磁数据预处理工作的自动化水平。由重庆地震台网的应用效果可知，该软件具有较为广泛的应用前景。
In the current geomagnetic data noise preprocessing process, there are shortcomings of inefficiency and processing quality that vary from person to person. Based on the mathematical morphology denoising method, a set of geomagnetic data noise is designed and developed based on C/C++ programming language and Qt development framework. The processing software is well designed to improve the automation level of geomagnetic data preprocessing work. According to the application effect of Chongqing Seismic Network, the software has a wide application prospect.
