1. A method comprising:
- projecting modulated light onto an occupant from a light source outside of a vehicle;
receiving reflections of the light source at a detector located outside of the vehicle;
determining three-dimensional data based on a time-of-flight of the reflections; and
detecting the occupant based on the three-dimensional data.

Abstract
Vehicle occupancy detection involves projecting modulated light onto an occupant from a light source outside of a vehicle. Reflections of the light source are received at a detector located outside of the vehicle. Three-dimensional data is determined based on a time-of-flight of the reflections, and the occupant is detected based on the three-dimensional data.

13. A system comprising:
-
a time-of-flight sensor configured to detect objects in an interior of a vehicle from outside of the vehicle; and a computing arrangement coupled to the time-of-flight sensor, the computing arrangement having a processor configured to; receive data from the time-of-flight sensor; detect an occupant of the vehicle based on the data; and signal the detection of the occupant to an end-user application. - View Dependent Claims (14, 15, 16, 17, 18, 19)
