Carlo Dal Mutto, CTO of Aquifi, presents the “Depth Cameras: A State-of-the-Art Overview” tutorial at the May 2018 Embedded Vision Summit.
In the last few years, depth cameras have reached maturity and are being incorporated in an increasing variety of commercial products. Typical applications span gaming, contactless authentication in smartphones, AR/VR and IoT. State-of-the-art depth cameras are based on three fundamental technologies: stereo vision, time-of-flight (ToF) and structured light (SL). These technologies are available in rather different implementations, which are characterized by specific properties in terms of measurement quality (e.g., precision, accuracy, range and resolution) and in terms of system requirements (e.g., power consumption, size, computational requirements).
This talk provides an overview of the fundamentals behind stereo, ToF and SL technologies. It presents measurement characterization and system requirements of different implementations, and it explores a selection of depth cameras available in the market.
