The Importance of CMakeLists in 3D Vision

Currently, most 3D vision algorithms are written in C++, such as the SLAM algorithm. Since these algorithms are all written in C++, there must be reasons for this. The main reason is that the SLAM system has very high real-time requirements, and both speed and accuracy are crucial. Python also has acceleration methods, but overall, … Read more

Kimera-Multi: Robust, Distributed, Dense Metric-Semantic SLAM for Multi-Robot Systems

Kimera-Multi: Robust, Distributed, Dense Metric-Semantic SLAM for Multi-Robot Systems 0 Abstract This paper presents a multi-robot Simultaneous Localization and Mapping (SLAM) system named Kimera-Multi. Real-world applications require multi-robot SLAM systems to be robust, capable of identifying and rejecting erroneous inter-robot and intra-robot loop closures caused by perceptual confusion, and to rely solely on local (point-to-point) … Read more
