Method for detecting a speed of a vehicle and conclusive, visible allocation of the detected speed to the measured vehicle, in which - a measuring radiation is directed horizontally across a roadway over a predetermined angle range and when passing through a measurement zone vehicles generate measurement values, from which the speed and the changing position of the measured vehicle is determined, - the speed determined for the vehicle is compared to a predetermined limit speed, - when the limit speed is exceeded and a predetermined distance, which forms a sharp image of the angle range and which is a photo distance (e foto), is determined, an electronic image of the vehicle concerned is captured and is stored as digitized image, and a marking, which is superimposed on the image, is generated from the measurement data for clear identification of the vehicle, characterised in - that the measuring radiation is a pulsed laser radiation by which the angle range is repeatedly scanned, - that measurement values are generated in each scan, which form a plurality of measurement value pairs, consisting of an instantaneous scanning angle (ε n) and a distance (e n), and each represent a measurement point (P n) in the angle range which defines an impact point on the vehicle, - that the measurement value pairs of the last scan at the trigger time of the camera are stored, - that the measurement value pairs which each define an object angle are assigned to a group and the marking is generated from the group containing the photo distance (e foto) as measurement value and is stored as digitized marking, and - that the digitized image and the digitized marking are superimposed, in order to visualize them on a screen or print an evidence photo. - a measuring radiation is directed horizontally across a roadway over a predetermined angle range and when passing through a measurement zone vehicles generate measurement values, from which the speed and the changing position of the measured vehicle is determined, - the speed determined for the vehicle is compared to a predetermined limit speed, - when the limit speed is exceeded and a predetermined distance, which forms a sharp image of the angle range and which is a photo distance (e foto), is determined, an electronic image of the vehicle concerned is captured and is stored as digitized image, and a marking, which is superimposed on the image, is generated from the measurement data for clear identification of the vehicle, - that the measuring radiation is a pulsed laser radiation by which the angle range is repeatedly scanned, - that measurement values are generated in each scan, which form a plurality of measurement value pairs, consisting of an instantaneous scanning angle (ε n) and a distance (e n), and each represent a measurement point (P n) in the angle range which defines an impact point on the vehicle, - that the measurement value pairs of the last scan at the trigger time of the camera are stored, - that the measurement value pairs which each define an object angle are assigned to a group and the marking is generated from the group containing the photo distance (e foto) as measurement value and is stored as digitized marking, and - that the digitized image and the digitized marking are superimposed, in order to visualize them on a screen or print an evidence photo.
