Drone Visual-Inertial Navigation System (VINS) Simulation

1. Overview

This is a drone simulation written in Matlab. The simulation employs a PID controller to guide a quadcopter along a given smooth trajectory and generate ground truth, IMU data, and monocular camera images using a pinhole model. For instance, we simulate the drone flying in a circular pattern assuming that the camera is oriented downward, capturing randomly generated ground features. The resulting dataset can be utilized to evaluate the performance of a visual-inertial navigation system (VINS).

2. Prerequisites

• Matlab R2022b.

3. Usage

• The /IMU/drone.m script generates the /Datasets/drone_IMU.mat dataset includes IMU measurements (Forward-Right-Down), IMU specifications, and ground truth data (Forward-Left-Up).
• The /Camera/makeCamera.m script generates ground features based on the data from /Datasets/drone_IMU.mat, records monocular camera data, and then combines all the information into the final dataset named /Datasets/drone_IMU_camera.mat.
• Additionally, we provide a simplified version of an Extended Kalman Filter for Visual-Inertial Navigation System (EKF-VINS) algorithm to validate the dataset.
