Enabling the autonomous vehicle to perceive the environment is the core technology in autonomous driving. In this project, In this project, I used data from stereo camera with feature extractions from images and IMU measuring linear velocity and angular velocity to implement the Visual Inertial Simultaneous Localization an Mapping(VI-SLAM). Following the instruction, I did IMU Localization via EKF Prediction first to get the trajectory. And then I did Landmark Mapping via EKF Update to update the landmarks on the map. Finally, I combined these two steps to implement an IMU update step based on the stereo-camera observation model to obtain a complete visualinertial SLAM algorithm.
