Gemini 330 Series 3D Vision Camera

The Gemini 330 series represents Orbbec’s flagship stereo vision platform for robotics applications, combining active and passive stereo vision technologies to deliver reliable depth perception across diverse operating conditions. These cameras serve as the primary vision system for numerous rehabilitation robots, hospital logistics AMRs, and healthcare automation systems throughout China and globally.

Product Overview

Introduced as the third generation of Orbbec’s stereo vision technology, the Gemini 330 series incorporates custom ASICs for on-device depth processing, enabling real-time perception without heavy computational loads on host systems. The product line spans multiple variants optimized for different deployment scenarios—from compact modules for robotic arms to ruggedized units for outdoor medical logistics.

Unlike consumer depth cameras, the Gemini 330 series targets professional robotics developers with industrial-grade reliability, full SDK support, and integration with major robotics frameworks including ROS/ROS2 and NVIDIA Isaac.

Key Features

Gemini 330’s custom ASIC delivers on-device depth computation across a 0.2–10 m range, enabling rehabilitation robots, hospital AMRs, and surgical systems to perceive their environments without heavy host CPU loads.

• Hybrid Stereo Vision: Combines active IR projection with passive stereo for operation in both indoor and outdoor environments
• Custom ASIC Processing: On-device depth computation reduces latency and host CPU requirements
• Wide Temperature Range: Industrial models operate from -20°C to 65°C
• Multi-Camera Synchronization: Supports synchronized operation of up to four cameras
• NVIDIA Integration: Compatible with Isaac ROS, Jetson platforms, and newly announced Jetson Thor

Product Variants

Technical Specifications

Depth resolution up to 1280×800, frame rate up to 30 fps, and FOV up to 104°×87° make the Gemini 330 series compatible with ROS/ROS2, NVIDIA Isaac, and OpenCV.

Clinical Applications

Rehabilitation Monitoring

Combined with skeleton tracking software, Gemini cameras enable rehabilitation systems to:

• Track body movements with detailed joint angle measurements
• Create personalized exercise programs based on patient capabilities
• Monitor progress over time with objective data collection
• Provide gamified interactive training experiences

Healthcare providers including MIRA Rehab have integrated Gemini cameras into therapeutic platforms, improving patient engagement and rehabilitation outcomes.

Hospital Logistics

Autonomous mobile robots equipped with Gemini cameras navigate hospital corridors, delivering medications, specimens, and supplies. One of Japan’s top three automakers developed their hospital logistics robot using Gemini 2 stereo cameras for autonomous navigation in clinical environments.

Patient Positioning

In radiological imaging departments, 3D vision systems utilizing Gemini technology provide:

• Automatic body positioning through visual cues
• Reduced radiation dose through optimized scan settings
• Consistent positioning regardless of technician experience
• Digital records of patient anatomy for treatment planning

Fall Detection

Non-contact monitoring systems using depth cameras detect fall risks in real-time, particularly valuable for:

• Elderly care facilities
• Hospital patient rooms
• Home healthcare settings

Deployment Considerations

Not a Medical Device

Gemini 330 series cameras are general-purpose depth sensors. Medical device manufacturers integrate these cameras into their certified systems and take responsibility for regulatory compliance. The cameras themselves do not carry NMPA, FDA, or CE medical device certifications.

Integration Support

Orbbec provides full SDK and documentation for robotics developers. The cameras integrate with:

• Robot Operating System (ROS/ROS2)
• NVIDIA Isaac for visual SLAM and perception
• OpenCV for computer vision applications
• Custom robotics frameworks

OEM Manufacturing

Orbbec offers complete OEM services for robotics companies, including camera modules, subassemblies, and full robot manufacturing through their Shunde facility.

Frequently Asked Questions

What is the difference between Gemini 335 and 336?

The Gemini 336 offers enhanced performance in high-ambient-light outdoor conditions compared to the 335. Both share the same form factor and interface, allowing developers to select based on deployment environment.

Can Gemini cameras be used in surgical robots?

Gemini cameras can provide vision capabilities for surgical robot systems, but the camera itself is not a certified medical device. Surgical robot manufacturers must validate and certify their complete systems through appropriate regulatory pathways.

How do Gemini cameras compare to Intel RealSense?

Gemini 330 series cameras are positioned as alternatives to discontinued Intel RealSense products. Orbbec has specifically designed the Gemini EW as a drop-in replacement for RealSense D415, with similar specifications and mounting options.
