Gemini 2 L

Q: What is the Orbbec Gemini 2 L and what makes it distinct?

The Gemini 2 L is a 3D camera based on active stereo IR technology with a 100mm baseline and an Orbbec custom ASIC for high-quality depth processing. It offers a depth field of view of up to 101 degrees diagonally and adds a proximity sensor for close-distance single-point ranging, which eliminates blind spots in depth measurement across the full 0 to 10m range. An internal IMU enables motion and position tracking.

Q: What depth range and accuracy does the Gemini 2 L provide?

The Gemini 2 L outputs high-quality depth data across a 0.2 to 10m range, with a Root Mean Squared Error of 2% or better at 4m thanks to its 100mm baseline. Depth resolution reaches up to 1280x800 at 30fps and RGB up to 1280x800 at 30fps. Its close-distance single-point ranging keeps depth data consistent throughout the range without blind spots.

Q: What field of view does the Gemini 2 L offer?

The Gemini 2 L provides a depth field of view of up to 101 degrees and a Depth-to-Color (D2C) field of view exceeding 90 degrees. The depth field of view is 91 degrees horizontal by 66 degrees vertical and the RGB field of view is 94 degrees horizontal by 68 degrees vertical, giving broad scene coverage for mapping and interaction tasks.

Q: How does the Gemini 2 L handle motion and dynamic scenes?

The Gemini 2 L features a global shutter for both RGB and IR cameras and a 6-axis IMU for real-time motion and orientation tracking. The global shutter provides uniform exposure across all pixels, minimizing motion blur and distortion in dynamic scenes. It also offers preset scene-based working modes, including a Dimensioning mode useful for measurement and reconstruction.

Q: How does the Gemini 2 L connect and what are its physical characteristics?

The Gemini 2 L connects over USB 3.0 and USB 2.0. Typical average power consumption is under 3.0W, with a maximum peak under 10.0W. It outputs point cloud, depth map, IR, and RGB data. The camera measures 124mm x 29mm x 26mm, weighs 144g, and provides one 1/4-20 UNC and two M3 mounting points. Its operating range is 0 to 40 degrees Celsius for indoor and semi-outdoor use.

Q: What are the typical applications for the Gemini 2 L?

The Gemini 2 L is used for AMRs, where it supports real-time 3D mapping, navigation, and object detection and avoidance; for cobots, enabling collaborative robots to respond to human commands and gestures and interact safely; and for human body reconstruction, where 3D data capture supports accurate whole-body scanning and modeling.

Q: Does the Gemini 2 L support multi-camera synchronization?

Yes. The Gemini 2 L enables precise synchronization of depth and color frames and supports multiple-device synchronization, which is valuable for applications requiring multi-angle coverage or wide-area capture. It is easy to set up with the Orbbec SDK on Linux and Windows.

The Orbbec Gemini 2 L is based on active stereo IR technology with a baseline of 100mm and is equipped with Orbbec’s latest custom ASIC for high quality depth processing. It has a depth Field of View (FoV) of up to 101° diagonally and operates with single cable USB 3.0 for power and connectivity. The camera also has a proximity sensor for close distance single point ranging, which eliminates any blind spot in depth measurements within the entire 0-10m range. An internal IMU enables motion and position tracking.

Gemini 2 L is easy to set up and operate with the Orbbec SDK, and the camera delivers extremely accurate and reliable data in various lighting conditions from pitch black to semi-outdoor.
