Aiming at the fact that there is no data processing software for multiple drilling imagers in coal mine, the overall architecture design of the software is proposed, based on the analysis of output data source of drilling imager, a trajectory display software for drilling imager compatible with multiple instruments is designed based on Visual Studio+SQLite. The software realizes multi-source data management of borehole attitude data and graphic data, 2d and 3d drawing generation and graphic operation of borehole trajectory, generation and operation of borehole histogram, etc. The application results show that this software provides friendly human-machine interface and has high application value.
