Kimera

Kimera is a C++ library for real-time metric-semantic simultaneous localization and mapping, which uses camera images and inertial data to build a semantically annotated 3D mesh of the environment. Kimera is modular, ROS-enabled, and runs on a CPU.

Kimera comprises four modules:

• A fast and accurate Visual Inertial Odometry (VIO) pipeline (Kimera-VIO)
• A full SLAM implementation based on Robust Pose Graph Optimization (Kimera-RPGO)
• A per-frame and multi-frame 3D mesh generator (Kimera-Mesher)
• And a generator of semantically annotated 3D meshes (Kimera-Semantics)

Click on the following links to install Kimera's modules and get started! It is very easy to install!

Open-Source Datasets

In addition to the real-life tests on the Euroc dataset, we use a photo-realistic Unity-based simulator to test Kimera. The simulator provides:

• RGB Stereo camera
• Depth camera
• Ground-truth 2D Semantic Segmentation
• IMU data
• Ground-Truth Odometry
• 2D Lidar
• TF (ground-truth odometry of robots, and agents)
• Static TF (ground-truth poses of static objects)

Using this simulator, we created several large visual-inertial datasets which feature scenes with and without dynamic agents (humans), as well as a large variety of environments (indoors and outdoors, small and large). These are ideal to test your Metric-Semantic SLAM and/or other Spatial-AI systems!
