Abstract

Method and apparatus for reading tachograph discs employs a document scanner feeding data to a personal computer and associated printer. Analysis of electronic data from the scanner enables first the establishment of the disc type and orientation, followed by identification of the data traces and analysis of these by reference to concentric bands of the disc which are converted from circular to linear form, and by a line-following process, as part of the data-processing method. Activities and violations of international vehicle regulations can be identified by counting the crossing points of the graphic trace with respect to predetermined traces representing vehicle use parameters such as speed. The computer produces a graphic display or printed summary of the data or image from the disc. <IMAGE>
