Based on G2O - general graph optimization framwork, the project implements a key-frame based
visual odometry SLAM frontend. It uses 3D-2D matching for solving bundle adjsuments on a ELP
stereo camera. 3D point cloud of key frame is visualized.
The python based open source project receives great popularity among the drone community. The
simulator includes sensors modeling, EKF based sensor fusion and state estimation, quadcopter
dynamics, minimum snap trajectory generation and control.
