1. An assembly arrangement for determining at least one feature for identifying a vehicle moving along a traffic lane, comprising;
- a light sensitive sensor for recording an image of the vehicle,an evaluation device for determining the at least one feature on the image,wherein the light sensitive sensor comprises one single line scan camera only, which adapts a number of lines per unit of time of the image to a velocity of the vehicle, and wherein the singly line scan camera is arranged laterally beside the traffic lane, and either aligned aslant at an acute angle to the traffic lane against a driving direction of the vehicle, or aslant at an obtuse angle to the traffic lane in driving direction of the vehicle, andthe assembly further including a controller for the single line scan camera, wherein a sampling rate of the recorded lines is adjustable by the controller, wherein the number of lines per unit of time of the image is adapted to the velocity of the vehicle such that the sampling rate of the single line scan camera is adapted to the velocity of the vehicle.

Abstract
An arrangement for determining at least one feature of a vehicle moving along a traffic lane, having a light sensitive sensor for recording an image of the vehicle and having an evaluation device for determining the at least one feature on the image, as well as a method for determining at least one feature of a vehicle moving along a traffic lane, especially by means of such an arrangement, wherein an image of the vehicle is recorded with a line scan camera and the image is evaluated for determining at least one feature of the vehicle.

7. A method for determining at least one feature for identification of a vehicle moving along a traffic lane, including the steps of:
- recording an image of the vehicle with at least one line scan camera and analyzing the image to determine the at least one feature of the vehicle, wherein a number of lines per unit of time of the image is adapted to a velocity of the vehicle, determining round objects detected during the analysis of the image;
wherein the number of lines per unit of time of the image is adapted to the velocity of the vehicle such, that a sampling rate of the line scan camera is adapted to the velocity of the vehicle while the image is recorded; and wherein the sampling rate of the line scan camera is adapted such that a distortion of the image due to the velocity of the vehicle is corrected. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
