An optical capturing device includes a holder; a first optical sensor possessing a first field angle centered on a first optical axis; a second optical sensor possessing a second field angle centered on a second optical axis; and a third optical sensor possessing a third field angle centered on a third optical axis. A traffic enforcement device can include such an optical capturing device.

Optical capturing device comprising first, second and third optical sensors capturing first, second and third fields of view

The invention relates to a process for monitoring vehicles on a road by a system comprising at least one radar sensor and a second sensor different from the radar sensor, wherein the second remote sensor is a time-of-flight optical sensor or optical image sensor, the process comprising a temporal readjustment and a spatial matching in order to obtain a set of measurement points each assigned to first characteristics derived from the radar data and second characteristics derived from the optical data, the determination of the radar vehicle trackings and of the optical vehicle trackings, a comparison of similarity between the radar vehicle trackings and the optical vehicle trackings, the elimination of the radar vehicle trackings for which no optical vehicle tracking is similar, the process comprising monitoring a parameter derived from first characteristics of a retained radar vehicle tracking.

Process for monitoring vehicles by a plurality of sensors

The invention provides a distinguishing device for distinguishing, between vehicles passing in front of the device, a heavy goods vehicle (HGV) from a coach including over its entire length windows between a top side member and a bottom side member, the device comprising:
