<title>Visual system for automatic car registration</title>

Abstract

ABSTRACT In car assembly plants, when the car assembly process has finished, it is necessary to carry out a registration process which certifies that all the identification labels placed in specific parts of the vehicle (motor, chassis, board, windshield, right front post, etc.) correspond with a particular car unit. In this paper we propose a system for capturing and processing car identification labels. The system captures the required images for the registration process using a CCD camera with an appropriate mount. Images are analyzed and stored by the system, generating a report, where all the captured visual information is included. The information is further stored in a way, that allows the retrieval of each report. Results and discussion about the system are presented.

INTRODUCCTION In car assembly plants, when the car assembly process has finished, it is necessary to carry out a registration process which certifies that all the identification labels or VIN (Vehicle Identification Number) placed in specific parts of the vehicle (motor, chassis, board, windshield, right front post, etc.) correspond with a particular car unit. VIN numbers are used to identify uniquely vehicles around the world. They codify information about country of origin, manufacturer, assembly factory, and specific characteristics of a particular vehicle. The registration process is useful for example, when a car accident arise, and the factory or the driver wants to know if a determined part of the car has passed the quality tests without errors. Other situation when the registration process is useful , occurs when a car is stolen and the motor number is erased and minted again. A system can discover this change if it checks the other identification labels for consistency among themselves and with the car characteristics (model, color, etc.). 1.1.
