National Mineral Resource Utilization Surveyis an important national conditions survey in the field of mineral resources. Mine location is a key factor affecting the reliability of the results. Aiming at the problem of some inaccurate mine location,this paper breaks the traditional field verification mode,combined with mine contour and terrain feature point cloud data,with the improved SURF operator that the block matching method,studies the mine image with the reference image automatic registration,achieves to locate mine location quickly. The experimental results show that the improved SURF operator has rapid matching speed and good robustness to the mine with rotation and offset problem,achieves a higher matching result to medium and small scale mine image,provides a new approach for fast and accurate mine positioning.
