Real-Time Video Stitching for Mine Surveillance Using a Hybrid Image Registration Method
Video stitching technology provides an effective solution for a wide viewing angle monitoring mode for industrial applications. At present, the observation angle of a single camera is limited, and the monitoring network composed of multiple cameras will have many overlapping images captured. Monitor...
