Intelligent laser tracking system and method for mobile and fixed position traffic monitoring and enforcement applications

摘要

An intelligent laser tracking system and method for mobile and fixed position traffic monitoring and enforcement applications. The system disclosed herein can autonomously track multiple target vehicles with a highly accurate laser based speed measurement system or, under manual control via a touch screen, select a particular target vehicle of interest. In a mobile application the police vehicle speed is determined through the OBD II CAN port and updated for accuracy though an onboard GPS subsystem. The system and method of the present invention simultaneously provides both narrow and wide images of a target vehicle for enhanced evidentiary purposes. A novel, low inertia pan/tilt mechanism provides extremely fast and accurate target vehicle tracking and can compensate for geometrical errors and the cosine effect.

主权项

1. A tracking system for monitoring the speed of one or more target vehicles comprising:
a processor; a visual sensor subsystem coupled to said processor; a laser speed measurement subsystem coupled to said processor; and a pan/tilt subsystem responsive to said visual sensor subsystem coupled to said processor for autonomously movably supporting said visual sensor and laser speed measurement subsystems, said system determining a speed of said one or more target vehicles based on input from said laser speed measurement subsystem wherein said visual sensor subsystem is operative to identify one or more moving targets and cause said pan/tilt subsystem to aim said visual sensor subsystem and said laser speed measurement subsystem at said one or more moving targets; wherein said visual sensor subsystem is operative to cause said pan/tilt subsystem to aim said visual sensor subsystem and said laser speed measurement subsystem at each of said one or more moving targets; further comprising: an operator input device coupled to said processor for manually selecting a particular one of said one or more moving targets.
