Today, Intel introduced the Intel® RealSense™ Depth Camera D455, a new stereo-based depth camera equipped with a longer range and increased precision that achieves twice the range of previous generation models. The D455 grants developers the freedom to design vision-based solutions that give devices the ability to see, understand, interact with and learn from their environments.
“The Intel RealSense family of products now offers developers more choices. The D455 expands the capabilities of our stereo camera line allowing us to address a wider range of applications with longer range use cases and allowing users to design solutions that best meet their needs.”
–Sagi BenMoshe, Intel corporate vice president and general manager of the Intel RealSense Group
How It’s Different: Stereo depth works in a wide variety of lighting conditions. With its long range, enhanced accuracy and easy deployment, the D455 camera is a powerful tool that can be used for both indoor and outdoor applications.
For example, a key requirement for autonomous movement of a robot is the ability to “see” its environment. The longer range and improved coverage provided by the D455 allows a robot to scan its environment and make critical choices, like obstacle avoidance.
In healthcare applications, by mounting the D455 in the corner of a hospital room, staff can closely monitor patients through alerts based on movement via third-party software. This enhances patient care substantially as it frees up critical time for healthcare workers to tend to other priorities.
Why It’s Important: The D455 camera increases the optimal range to 6 meters, making it twice as accurate as the current D400 cameras without sacrificing field of view. The D455 also includes global shutters for the depth and RGB sensors to improve correspondence between the two different data streams and to match the field of view between the depth sensors and the RGB sensor. In addition, this camera also integrates an IMU to allow for refinement of its depth awareness in any situation where the camera moves.
How It Works: The D455 achieves less than 2% Z-error at 4 meters with several improvements. First, the depth sensors are located 95 millimeters apart, providing greater depth accuracy at a longer range. Second, the depth and RGB sensors are placed on the same stiffener, resulting in an improved alignment of color and depth. Lastly, the RGB sensor has the same field of view as the depth sensors, further improving correlation of depth and color points.
The D455 utilizes the same SDK 2.0 as the entire portfolio of Intel RealSense devices to leverage existing code base, allowing for easy upgrades from any of Intel’s depth cameras with virtually no development time.
