VIO (Visual-Inertial Odometry)

Visual-Inertial Odometry (VIO) is a technology that combines camera images and inertial sensors (like accelerometers and gyroscopes) to determine a device's position and movement over time. It works by analyzing visual data to map surroundings and using inertial sensors to measure motion dynamics. By fusing these inputs, VIO provides accurate real-time tracking of a device’s trajectory, even in challenging environments where one data source alone might be insufficient. This approach is widely used in robotics, drones, and augmented reality to enable precise navigation without relying solely on external GPS signals.
