Product Introduction
The Orbbec Gemini 330 series 3D cameras integrate Orbbec’s latest proprietary depth engine ASIC, combining both active and passive stereo vision technologiesfor seamless operation in both indoor and outdoor conditions. By performing depth image generation and spatial alignment of depth images to color images internally, the camera achieves minimal data latency and significantly reduces reliance on host computers. The cameras are preset with multiple operating modes, making them adaptable and efficient for various application scenarios. A flexible and comprehensive frame synchronization mechanism simplifies and enhances the scalability of multi-camera operations.
The Orbbec Gemini 330 series includes the following components:
- Orbbec’s latest proprietary depth engine ASIC
- Stereo IR Module
- Speckle Emission Module (LDM)
- RGB Module
- Laser Ranging Module (LRM)
- IMU Module
- Orbbec SDK
- Wrappers (e.g., ROS1 / ROS2 / Python)
Orbbec Gemini 330 series cameras are available in Orbbec online store, which also offers a wide selection of multi-camera synchronization accessories.
Orbbec SDK
The Orbbec SDK provides low-level sensor access to Gemini 330 series cameras hardware sensors and device configuration. For more details on the Orbbec SDK, please refer to Orbbec SDK architecture.
Orbbec SDK Features
The Orbbec SDK offers the following features, ready to use on the Gemini 330 series cameras upon installation:
- Depth camera access and mode control
- HDR support for depth
- Depth post-processing (e.g. decimation filter, spatial filter, disparity to depth)
- RGB camera access and control (e.g., exposure and white balance)
- Synchronized depth and RGB camera streams with configurable inter-camera latency
- External device synchronization control with configurable inter-device latency offsets
- Motion sensor (gyroscope and accelerometer) access
- Point cloud access and control
- Camera frame metadata access for image resolution, timestamps, etc.
- Device calibration data access
Camera Tools
Orbbec provides the following tools:
- Orbbec Viewer tool, used for monitoring device data streams and configuring different modes,
- Orbbec Quality Assessment Tool, used for assessing camera depth quality.
For detailed instructions on using the Orbbec Viewer, please refer to Explore camera functions in Orbbec Viewer.
