Omnidirectional sensor
A novel imaging system with no moving parts that provides constant 360-degree coverage.
We are actively working to identify potential applications for this invention. Please get in touch if you would like to learn more about the technology, or for an informal discussion.
Background
Collaborative robots, autonomous systems and driverless vehicles are quickly being deployed in all kinds of environments. One of the main challenges is how to improve their perception and understanding of their surroundings. Currently, the most common sensors used to detect objects and obstacles are cameras and lidar systems.
However, both have their limitations. RGB-D cameras have a limited range and angle of detection. Lidar devices are costly and require motors to obtain measurements in all directions.
Solution
Our innovative approach uses a novel optical arrangement coupled to a suitable sensor to capture a full 360-degree “disc-shaped” image of its surroundings without the need for any moving parts. A working prototype demonstrating the use of the technology for person sensing (e.g. for follower robots) has been developed, as seen in the video above.
Benefits
The device offers the following potential advantages in comparison to similar systems:
- Constant 360-degree sensing capability.
- No moving parts (such as the spinning motors commonly used in lidar devices).
- Sensor agnostic. The current prototype uses a thermal camera, but other types of sensors could be used.
- No personal identification. Because the device captures a horizontal image slice (rather than a full field image), it protects the identity of observed individuals.
- Data and energy efficient.
