Computer-Implemented System And Method For Detecting Vehicle Occupancy
First Claim
1. A computer-implemented system for determining vehicle occupancy, comprising:
- light beam pulses emitted from a lidar system to a vehicle passing by the lidar system;
a scanner to generate scans of an object from the light beam pulses, each scan comprising;
a signal receipt module to receive a signal from each of the beam pulses reflected at a point of reflection along a segment of the passing vehicle;
a time module to measure a time from when each beam pulse was emitted from the lidar system to receipt of the signal;
a distance module to calculate a distance of the signal from the lidar system using the measured time;
a position module to position the points of reflection for that vehicle segment in relation to one another as a scan;
a compiler to compile the scans in a consecutive order according to the vehicle and generating a three-dimensional image of an interior of the vehicle from the consecutive scans; and
an occupancy determination module to determine at least one of a presence and absence of vehicle occupancy based on the three-dimensional image.

Abstract
A computer-implemented system and method for detecting vehicle occupancy is provided. Light beam pulses emitted from a lidar system are applied to a passing vehicle. Scans of an object are generated from the light beam pulses. A signal is received from each of the beam pulses reflected at a point of reflection along a segment of the vehicle. A time is measured from when each beam pulse was emitted to receipt of the signal. A distance of the signal from the lidar system is calculated using the measured time. The points of reflection for that vehicle segment are positioned in relation to one another as a scan. The scans are compiled in a consecutive order according to the vehicle and a three-dimensional image of an interior of the vehicle is generated from the consecutive scans. A presence or absence of vehicle occupancy is determined based on the three-dimensional image.
