A simple method for finding the extrinsic calibration between a 3D lidar and a 6-dof pose sensor

DroneBridge is a system based on the WifiBroadcast approach. A bidirectional digital radio link between two endpoints is established using standard WiFi hardware and a custom protocol. DroneBridge is optimized for use in UAV applications and is a complete system. It is intended be a real alternative to other similar systems, such as DJI Lightbridge or OcuSync.

The fuse stack provides a general architecture for performing sensor fusion live on a robot. Some possible applications include state estimation, localization, mapping, and calibration.

A lightweight, accurate and robust monocular visual inertial odometry based on Multi-State Constraint Kalman Filter.
