Phobos
High-resolution stereo vision camera
Stereo vision camera ideal for fast-rate, accurate mapping over wider areas
Real-time stereo mapping using Phobos
Phobos is a high-resolution stereo vision camera system that uses 5 Megapixel cameras and can operate at 30 fps over a USB3.0 interface. The cameras use a global shutter and are suitable for imaging moving targets.
- Synchronised data flow from the camera
- Global Shutter – monochrome
- Baseline – 300mm
- Frame rate – 75fps
Overview
Phobos is the result of a successful project within Nuclear Decommissioning where a high-resolution solution capable of being mounted on a robot and deployed remotely were key criteria.
It is currently in operation in high value manufacturing, particularly, Steel (as-cast and hot plate), and Glass production. Phobos has been integrated with machine learning for in-process defect recognition and identification. Early identification of defects allows for product reform prior to cooling, saving waste, reducing energy consumption, and reducing carbon emissions.
Key benefits:
- Designed for harsh and industrial environments
- Global shutter provides artifact-free images in movement
- Global shutter enables accurate stereo synchronisation
- Can be integrated with other sensors
- Can be mounted on a robot
- Customisable design and applications
- Deep learning applications such as object detection & recognition, defect detection & recognition
A software toolkit is provided to allow users to re-calibrate the cameras, acquire and match stereo imagery, and view/output 3D point clouds using i3Dr’s state-of-the-art stereo matching algorithms. The instrument is compatible fully with OpenCV and ROS.
