Device for vehicle measuring
First Claim
1. A device for measuring a vehicle on a roadway, comprising:
- a carrier structure, which has a support axis that can be oriented transversely over the roadway;
a plurality of transmitter elements, which are distributed along the support axis on the carrier structure and each downwardly emit a light measuring beam, each light measuring beam having an emission direction that is normal to the support axis;
at least one receiver element, which is installed on the carrier structure and receives reflected light measuring beams; and
an evaluation unit, which is connected to the transmitter and receiver elements for time of flight measurement and, based thereon, measurement of a vehicle;
wherein the emission directions of at least two transmitter elements are not parallel to each other, transmitter elements having mutually parallel emission directions form a group, and the device has at least two groups.

Abstract
A device for measuring a vehicle on a roadway, comprising a carrier structure, which has a support axis that can be oriented transversely over the roadway, a plurality of transmitter elements, which are distributed along the support axis on the carrier structure and each downwardly emit a light measuring beam, each light measuring beam being located in an emission direction extending normal to the support axis, at least one receiver element, which is installed on the carrier structure and receives reflected light measuring beams, and an evaluation unit, which is connected to the transmitter and receiver elements for the time of flight measurement and, based thereon, measurement of a vehicle, wherein the emission directions of at least two transmitter elements are not parallel to each other.
