Abstract:

The current software system of 3D automatic gravity and magnetic inversion has an inefficient work mode because of extremely time-consuming inversion calculation. This paper presents a new work mode in order to improve the work efficiency and the inversion result. A software system of 3D automatic gravity and magnetic inversion with real-time visualization was designed and developed. This system can real-timely visualize intermediate inversion result during the inversion process so that intermediate inversion results can be evaluated and then inversion parameters can be adjusted promptly based on evaluation of the intermediate inversion results. With this new work mode, the inversion process can be intervened and be led to a good inversion result in an efficient way. This paper presents the analysis and design work of this software system. Also, some key development techniques and design solution are presented.

Key words: 3D automatic gravity and magnetic inversion, real-time visual inversion, 3D visualization, software multi-threading
