INTELLIGENT LASER TRACKING SYSTEM AND METHOD FOR MOBILE AND FIXED POSITION TRAFFIC MONITORING AND ENFORCEMENT APPLICATIONS

摘要

Intelligent laser tracking systems and methods for mobile and fixed position traffic surveillance and enforcement applications. The system disclosed herein can autonomously track multiple target vehicles with a highly accurate laser based speed measurement system, or select a particular target vehicle of interest under manual control via a touch screen. In mobile applications, police vehicle speed is determined via the OBD II CAN port and updated via the built-in GPS subsystem for accuracy. The system and method of the present invention simultaneously provide a narrow image and a wide image of the target vehicle for improved evidence purposes. The new, low inertia pan / tilt mechanism provides extremely fast and accurate target vehicle tracking and compensates for geometric errors and cosine effects.
