Device for the visually impaired

Theia focuses on being cheap (<$300) and accessible to the visually impaired. It uses a Raspberry Pi 4 and a camera to detect objects and people in the environment. It then uses a intel realsense camera in order to properly communicate depth to the user. The below images summarize the pipeline. For more info read the paper or check out our poster. We additionally have a website with more info.
