Applications
Project 1. Combined Solution for Development & Productization
The Intel Realsense D435i seamlessly integrates a 6-axis IMU into its stereo Depth Camera, combining Intel’s vision processing module and high-performance processor into a compact design. This system delivers motion-aware depth data, enabling autonomous robots and Unitree platforms to track position and orientation with customizable software solutions.
Project 2. Ideal for Cameras in Motion
The D435i offers an ideal solution for robotic navigation and object recognition thanks to its wide field of view and global shutter sensor. This reduces blind spots and enhances low-light sensitivity, allowing Unitree robots to navigate effectively in dark environments.
Project 3. Complete Suite for Simple Integration
The D435i Depth Camera is part of the Intel Realsense D400 series, combining Intel’s latest depth-sensing hardware and software into easy-to-integrate products. Ideal for developers and innovators, the D400 series provides seamless out-of-the-box integration for intelligent vision-equipped solutions.
Why choose Intel Realsense D435i for Unitree?
Adding an IMU enhances depth awareness in dynamic situations where the camera is in motion. This facilitates SLAM, point-cloud alignment, and improves environmental awareness for Robotics and drones. With Intel Realsense SDK 2.0, IMU data is timestamped for precise alignment with high-quality depth data, making the D435i the perfect choice for Unitree robots and AR/VR applications.
