Occupancy sensing with perturbation-modulated light and distributed non-imaging color sensors
RPI ID: 2014-061-402Innovation Summary:This smart lighting system detects and adapts to occupancy patterns in real-time using distributed non-imaging color sensors and perturbation-modulated light. It builds a light transport model that estimates how light moves through a space, subtracts ambient lighting, and infers occupancy distribution. This allows...
