“Founded in 2014, Guardian Optical Technologies has developed breakthrough, patent-pending sensor technology for occupancy detection in vehicles, encompassing 2D, 3D and motion analysis in a single sensor designed to enable automobile manufacturers to produce safer, more convenient “”passenger aware”” vehicles at a lower cost.
Guardian enables occupancy detection for the entire cabin (all 5 seats). Guardian’s sensor is mounted in the celiling of the car. The sensor scans the entire vehicle using three layers of information:
1. 3D map
2. Video – machine learning and image recognition
3. Micro-vibration – detects movement up to 1 micrometre
Any living being could be detected (heartbeats generate micro-vibrations). These three layers of information create a rich source of real-time big data that includse the number of people in the vehicle, their exact location in the vehicle, the physical size and mass of the occupants, and differentiation between people and objects.”
