Abstract
The present subject matter relates to a method and a roadside unit for generating a digital record of a vehicle in a road toll system, comprising: capturing an image of the vehicle on a roadway; data-compressing the image depending on at least one of a confidence level obtained from the image for one or more characters therein by means of OCR, and a contrast parameter obtained from the image or a region of interest therein or a section of the latter, to generate the digital record; and sending the digital record from the roadside unit to a data center of the road toll system.

A method for generating a digital record of a vehicle in a road toll system, comprising, in a roadside unit of the road toll system:
- capturing an image of the vehicle on a roadway by means of a camera of the roadside unit;
- data-compressing the image at a compression ratio depending on at least a confidence level obtained from the image for one or more characters therein by means of OCR to generate the digital record;
- and
- sending the digital record from the roadside unit to a data center of the road toll system.
A roadside unit for generating a digital record for a vehicle in a road toll system, comprising:
- a roadside camera for capturing an image of the vehicle on a roadway;
- a data-compression unit configured to data-compress the image at a compression ratio depending on at least a confidence level obtained from the image for one or more characters therein by means of OCR to generate the digital record;
- and
- a transmitter connected to the data-compression unit and configured to send the digital record from the roadside unit to a data center of the road toll system.
