People Counting for Demand Controlled Ventilation Using 3D Time-of-Flight (ToF) Reference Design

Description

People counting for demand controlled ventilation using 3D time-of-flight (ToF) reference design is a subsystem solution that uses TI’s 3D ToF image sensor combined with tracking and detection algorithms to count the number of occupants present in a given area with high resolution and accuracy. The sensor technology is developed in standard CMOS, allowing systems to achieve very high integration at a lower system cost. Because ToF image sensor processes visual data in three dimensions, the sensor can detect the exact shape of a human body along with track the movement and location of people with unprecedented precision, including subtle movement changes. For this reason, ToF cameras are potentially capable of performing real-time people counting and people tracking functions much more effectively than traditional surveillance cameras and video analytics.
