As a combination of modern imaging technology, stereotactic technology, computer technology, and artificial intelligence technology, the surgical navigation system has been rapidly developed and applied in recent years. In recent decades, navigation systems have been used to aid in maxillofacial surgery, but rarely in the oral area. By comparing th...

... back-end optimization mainly eliminates and optimizes the error of the output results of the previous section, to improve the accuracy of mapping. In pose estimation, when the similarity of the two frames of images reaches a certain standard, then it is considered that a closed loop is formed, and all the marker points of the two frames of the image are optimized once, and the mark points after optimization are used for mapping, as shown in Figure 1 [13]. The sensors commonly used in classical vision SLAM are mainly monocular, binocular, and RGB-D cameras [13]. ...

Simultaneous Localization and Mapping (SLAM) technology has many applications, such as intelligent robots, autonomous driving, and smart cities. It is a key technology for achieving autonomous robot navigation and environmental awareness. Robots need to perceive the surrounding environment in real-time and construct maps while conducting autonomous...
This chapter is concerned with drone navigation in unknown, indoor environments. This necessitates using the onboard LiDAR and IMU sensors to solve the simultaneous localization and mapping (SLAM) problem. Control barrier functions (CBFs) augmented with circulation constraints are designed for motion planning. CBFs ensure that the drone can safely...
