Under the project SceneUnderLight started in 2015, Osram together with the University of Verona and the Istituto Italiano di Tecnologia (IIT) in Genova has successfully combined advanced research in computer vision and modern technology in lighting to create what the company describes as an invisible light switch.

Leveraging the latest technology to estimate the light propagation in offices in real-time and computing how much of it is perceived by the people, the invisible light switch adjusts lighting autonomously based on the presence of people and on their position within the offices. Especially in large open-plan offices, farther away luminaires may be dimmed without altering the comfort of employees and their sense of security.

According to Osram, the invisible light switch enables each person in the office to perceive the entire office as “all lit”, while lights, which are not visible or perceived from their location, are switched off. This approach is said to offer up to 65 percent in energy consumption savings. SceneUnderLight was funded by the EU within the Horizon 2020 framework as a Marie Skłodowska-Curie Actions Project.

Fabio Galasso, head of the computer vision R&D activities at Osram, brought together the team consisting of Marco Cristani, heading the department of Vision, Processing and Sound of University of Verona, and Alessio Del Bue, head of the Visual Geometry and Modelling Lab of IIT. Since 2015, the project members have targeted two main goals: the understanding of the light and scene structure in an office as well as the understanding of the human factor in an illuminated scene.

IIT provided unique expertise in the 3D light estimation in large and complex office scenes, from color and depth images provided by a modern RGB-D camera. University of Verona brought in expert knowledge and design skills for estimating the gaze of people and their future motion with deep neural network model.
