| 英文摘要 |
| Visual simultaneous localization and mapping (VSLAM) is a key technology for autonomous robots, autonomous navigation, and AR applications. With the development of deep learning, accurate and efficient semantic information has been widely used in VSLAM. Compared with traditional SLAM, semantic SLAM leverages semantic information to improve the accuracy and robustness of localization, and enhances environmental perception ability by object-level
reconstruction, which has became the trend in VSLAM research. In this survey, we provide an overview of semantic SLAM
techniques with state-of-the-art object SLAM systems. Four key issues of semantic SLAM are summarized, including object representation, object initialization methods, data association methods, and back-end optimization methods integrating
semantic objects. The advantages and disadvantages of the comparison methods are provided. Finally, we propose the
future work and challenges of object-level SLAM technology. Currently, semantic SLAM still faces problems such as
inaccurate object association and an unified optimization framework has not yet been proposed. How to effectively use and
maintain semantic maps for the application of decision and planning tasks, as well as integrate multi-source information to
enrich visual perception, will be future research hotspots. |
