Improved ORB-SLAM2 Algorithm Based on Information Entropy and Image Sharpening Adjustment [PDF]
Mathematical Problems in Engineering, 2020 Simultaneous Localization and Mapping (SLAM) has become a research hotspot in the field of robots in recent years. However, most visual SLAM systems are based on static assumptions which ignored motion effects. If image sequences are not rich in texture information or the camera rotates at a large angle, SLAM system will fail to locate and map.
