UC-AR0234-dual-imu | Dual Global Shutter · Hardware-Synchronized Stereo · 6-Axis IMU · Shared Hardware Time Base
Three Core Capabilities
Synchronized Stereo Vision: Two AR0234 global shutter cameras with hardware-synchronized left/right exposure.
Integrated Motion Sensing: 6-axis IMU providing 3-axis acceleration and 3-axis angular velocity, with sampling rates up to 600Hz.
Shared Hardware Time Base: Hardware timestamps associated with image frames and IMU data for customer-side temporal data association.
Designed for robotics engineering teams and OEM developers building their own visual and motion-data acquisition systems.
Robotics systems increasingly require visual observations and motion measurements to be collected together.
A stereo camera provides two synchronized visual perspectives of the environment. An IMU provides acceleration and angular velocity measurements as the device moves. A shared hardware time base provides timing information that allows customer software to associate image frames with corresponding inertial samples.
The Goobuy UC-AR0234-dual-imu combines these three capabilities in one camera module.
Stereo Image Acquisition
Two color AR0234 global shutter sensors capture synchronized left and right image streams for binocular vision and stereo-processing workflows.
Motion Data Acquisition
The integrated ST LSM6DSV IMU sensor records three-axis acceleration and three-axis angular velocity, with sampling rates up to 600Hz.
Common Hardware Time Reference
Image and IMU data carry hardware timestamps based on a common time base. The supplied Linux SDK is used to access and decode the timestamp information for customer-side data association.
Together, these capabilities provide a practical hardware foundation for engineering teams developing robotics perception, human-demonstration datasets, motion analysis and visual-inertial processing systems.
Robotics developers need real-world data to understand how humans interact with objects, tools and physical environments.
For manipulation and robot-learning workflows, video alone may not provide sufficient motion context. Synchronized stereo images and inertial measurements offer complementary visual and motion information.
The UC-AR0234-dual-imu can be integrated into customer-developed data collection equipment for:
Human manipulation demonstrations
Object handling and tool-use recording
First-person visual data collection
Robot-learning dataset acquisition
Human activity and motion analysis
Stereo visual observation during task execution
The dual-camera system captures synchronized color images, while the integrated IMU records device motion.
The shared hardware time base allows the customer's recording and processing software to associate visual and inertial measurements within the same data timeline.
This makes the module relevant to robotics startups, robot-learning companies and engineering teams developing their own human-demonstration capture hardware.
For first-person data collection, camera orientation and device movement are important parts of the recorded visual context.
The Goobuy stereo-IMU module can be evaluated for integration into:
Head-Mounted Vision Rigs
Stereo visual capture and motion sensing for head-mounted data collection devices used in robotics research and human activity recording.
Chest-Mounted Recording Equipment
Binocular image acquisition and device-motion data for wearable demonstration capture systems.
Portable Data Collection Devices
Compact camera hardware for mobile or portable visual-and-motion recording equipment.
Custom Robotics Research Equipment
Stereo-IMU imaging components for experimental perception and motion-data acquisition platforms.
The camera is an integration component, not a finished wearable recorder. Enclosure, mounting, battery, storage, recording software and application-level processing are provided by the customer's system.
Visual-inertial systems use camera observations and inertial measurements as complementary inputs for motion estimation and spatial perception.
The UC-AR0234-dual-imu provides:
Hardware-synchronized stereo image acquisition
Dual AR0234 color global shutter sensors
Integrated six-axis inertial sensing
Image and IMU hardware timestamps on a common time base
Linux SDK availability for data access
Potential development applications include:
Visual-inertial odometry (VIO) research
SLAM development
Stereo motion analysis
Egocentric tracking development
Robot localization research
Mobile robotics perception
Teleoperation and remote manipulation research
The camera supplies visual and inertial data, not finished VIO, SLAM, localization or mapping results. These functions require customer-developed or separately selected software and algorithms.
Both AR0234 sensors use global shutter technology.
Global shutter exposure captures the image frame simultaneously rather than exposing different image rows at different times as in rolling shutter imaging.
Combined with hardware-synchronized left/right exposure, this is useful for applications involving:
Moving robotic arms
Human manipulation demonstrations
Mobile robot movement
Conveyor-based inspection
Moving objects and equipment
Teleoperation operator-view systems
Hardware-synchronized exposure provides corresponding left/right image capture. The common time base additionally provides timing information for associating image and IMU data.
Important: A shared time base does not mean every IMU sample occurs exactly at a camera exposure instant. The SDK and customer-side processing pipeline are required to interpret and associate the timestamps.
The UC-AR0234-dual-imu uses a USB 3.1 interface and is designed for integration with compatible host computers and embedded systems.
Typical integration environments include:
Linux-based embedded computers
Robotics development platforms
Industrial PCs
AI edge computing devices
Custom wearable recording systems
OEM vision and sensing equipment
A Linux SDK is available for accessing the image and IMU timestamp workflow.
Standard UVC video viewing alone does not provide the complete image/IMU data workflow. The supplied SDK is required to decode timestamp information and associate image frames with IMU samples.
Customers should evaluate the actual USB host, SDK configuration, image output mode, CPU workload and continuous data acquisition performance before final system integration.
The 60fps stereo imaging mode uses MJPEG compression. It is not uncompressed dual-eye 60fps output.
Goobuy supplies the stereo-IMU camera hardware platform. Factory calibration is not included.
The following calibration procedures are the customer's responsibility and must be performed locally after the camera is installed in the final mechanical configuration:
Stereo camera calibration
Left/right camera intrinsic and extrinsic calibration
Camera-to-IMU spatial calibration
Application-specific sensor alignment and validation
Calibration should be performed using the customer's final mounting structure, camera position, operating environment and intended application.
Goobuy does not provide factory-calibrated stereo parameters, camera-to-IMU calibration files or calibration services as standard product deliverables.
The camera provides hardware-synchronized stereo exposure and image/IMU timestamps on a common time base. These hardware capabilities should not be interpreted as a guarantee of a particular synchronization error, calibrated sensor accuracy or application-level positioning performance.
Customers requiring specific synchronization tolerances, calibration evidence or additional triggering functions should confirm feasibility separately before ordering.
