Intel RealSense Depth Camera D435i

The Intel RealSense Depth Damera D435i combines the robust depth sensing capabilities of the D435 with the addition of an inertial measurement unit (IMU). The inertial measurement unit (IMU) is used for the detection of movements and rotations in six degrees of freedom (6DoF). An IMU combines a variety of sensors with gyroscopes to detect both rotation and movement in three axes, as well as pitch, yaw and roll. It is used in applications such as gaming and pointing devices as well as image stabilization. Adding an IMU allows your application to refine its depth awareness in any situation where the camera moves. This opens the door for rudimentary SLAM and tracking applications allowing better point-cloud alignment. It also allows improved environmental awareness for robotics and drones. The use of an IMU makes registration and calibration easier for handheld scanning system use cases and is also important in fields such as virtual/augmented reality and drones. When using the D435i, Intel's RealSense SDK 2.0 provides IMU data that is time stamped to align with our high quality depth data.
