Methods, systems and processor-readable media for parking occupancy detection utilizing laser scanning
First Claim
1. A parking occupancy detection method, comprising:
- determining a distance profile via a laser range finder with respect to an object by estimating a time difference between an emitted laser and a received laser with respect to monitoring at least one parking space;
scanning said at least one parking space and generating a measured distance profile via a programmable pan-tilt unit that communicates electronically with said laser range finder and controls a movement of said laser range finder to scan said at least one parking space and generate said measured distance profile; and
converting said measured distance profile to parking occupancy data by a signal processing unit based on data provided by said laser range finder to generate parking space estimates for use in compiling said parking occupancy data.

Abstract
Parking occupancy detection methods, systems and processor-readable media. A laser device unit includes a laser range finder, and a programmable pan-tilt unit is deployable on site to monitor one or more parking spaces. A laser emitting and receiving unit associated with the laser range finder determines the distance of an object by estimating a time difference between an emitted laser and a received laser. The laser range finder is controllable by the programmable pan-tilt unit and scans the parking spaces. A signal-processing unit can convert the measured distance profile to a parking occupancy data to provide continuous parking space estimation data for use in parking occupancy detection.
