Kimera-VIO is a library for accurate state estimation from stereo or mono cameras and IMU data. It can also generate 3D meshes and perform loop closure detection with GTSAM.
VIO的初始化是系统工作非常关键的部分，这部分可以参考vinsmono以及ORB作者写的的VIO文章《Visual-Inertial Monocular SLAM with Map Reuse》。 两篇文章思路比较相似，先是通过单目运动估计的方法获取多帧图像的位姿，然后以此为运动参考估计其他参数，整个过程和相机IMU ...
This guide covers setting up SLAM projects, on-device SuperPoint for localization, and syncing frames with IMU messages for accurate mapping and navigation.
Figure-2: Building blocks of Visual SLAM. Structure from Motion (SfM) is a more general concept compared to Visual SLAM but there are many commonalities as well. SfM is usually performed offline using unordered sequences of images. SfM is mostly concerned with creating a map of the environment using several images taken from different perspectives.
We present HybVIO, a novel hybrid approach for combining filtering-based visual-inertial odometry (VIO) with optimization-based SLAM. The core of our method is highly robust, independent VIO with improved IMU bias modeling, outlier rejection, stationarity detection, and feature track selection, which is adjustable to run on embedded hardware. Long-term consistency is achieved with a loosely ...
VIO-mono. The average parallax of tracked features between current frame and the latest keyframe is beyond a certain threshold. To avoid rotation-only parallax, rotation compensation via IMU integration is used. The number of tracked features goes below a certain threshold. ORB-SLAM (Surval of the fittest strategy) Time from last keyframe > 0.5s.
Visual Inertial Odometry (VIO) or Visual SLAM (VSLAM) can help augment your odometry with another sensing modality to more accurately estimate a robot's motion over time. This makes your autonomy system more reliable and gives you the ability to rely on odometry for localized movements (e.g. docking or interfacing with external hardware).
This method, known as VIO (visual-inertial odometry), improves estimation performance when there is a lack of distinctive features in the scene to track motion visually. SLAM (simultaneous localization and mapping) is built on top of VIO, creating a map of key points that can be used to determine if an area is previously seen.
Visual and Inertial Odometry and SLAM. Metric 6 degree of freedom state estimation is possible with a single camera and an inertial measurement unit. ... VIO is the only viable alternative to GPS and lidar-based odometry to achieve accurate state estimation. Since both cameras and IMUs are very cheap, these sensor types are ubiquitous in all ...
VINGS-Mono is a monocular (inertial) Gaussian Splatting (GS) SLAM framework designed for large scenes. The framework comprises four main components: VIO Front End, 2D Gaussian Map, NVS Loop Closure, and Dynamic Eraser. In the VIO Front End, RGB frames are processed through dense bundle adjustment and uncertainty estimation to extract scene geometry and poses. Based on this output, the mapping ...
