LICENSE PLATE RECOGNITION

 

 

Introduction

GV-LPR is a digital license plate recognition system that utilizes Neural Network Technology of artificial intelligence to identify vehicle license plates. It comprises a video capture card to acquire images, a software-based engine to recognize characters, a set of I/O modules to integrate with alarm and sensors, and a database to store images for event retrieval or analysis. 1, 2, or 4-lane real-time recording are available.

 

The Recognition

GV-LPR activates recognition process in two ways. One is by software motion detection, which detects vehicles passing through the camera and illuminator zone. Second is by I/O activation, which the action triggers recognition and recording on I/O activation. For example, a GV-LPR may be connected to a sensor such as magnetic loop detector, overhead laser scanner, or infrared sensor. When these devices are triggered, the system starts the recognition and sends the output signals to trigger devices like gate controller. The system supports two view modes including Camera Overview and Picture-in-Picture with ease of monitoring.

 

The Integration

The system provides multiple I/O points for connection to devices such as gate controller, infrared detector, loop detection system, or alarms. By exporting the database that logs the captured license plate numbers, GV-LPR can be integrated to systems such as GV-series DVR or ticketing system.

 

Installations

The GV-LPR software currently recognizes license plates of these countries: UK , Italy , Spain , Taiwan and Japan . More are to be implemented.

High recognition speed: < 0.3 second

Integrates with GV-series DVR to retrieve video footage by license plate number

Vehicle counter feature tracks number of vehicles remaining in the parking lot

by counting vehicles entering and exiting the gate

Camera overview brings focuses on either the vehicle or the driver

License plate recognition database are processed and stored in

Microsoft Access Database for easy and multiple applications

Multiple recognition technology is applied until a recognition result is reached

Alarms will be triggered when an unauthorized or unrecognizable

vehicle is spotted

Picture-in-Picture window provides camera overview and

the last recognized image

Video or AVI file is used as recognition input source

Digital watermark technology is applied to verify authenticity of video clips

Text overlay displays license plate numbers on recorded video image

Activates recognition by sensor triggers, video motion detection or Hot Key

Recognition result triggers I/O Relay or user-defined application
