METHOD AND SYSTEM FOR DETERMINING A VEHICLE SPEED
The invention relates to a method for determining the speeds of vehicles (2) passing a detection unit (1), wherein the speed of the passing vehicles is measured by a measuring device (3), and in the event that the reading of the speed of a vehicle exceeds a specified maximum speed an imaging and pro...

| description | The invention relates to a method for determining the speeds of vehicles (2) passing a detection unit (1), wherein the speed of the passing vehicles is measured by a measuring device (3), and in the event that the reading of the speed of a vehicle exceeds a specified maximum speed an imaging and processing device is prompted to take a first picture and with some time delay (?T) a second picture of said vehicle using a digital image sensor, so as to calculate a calculated value from said two images, and wherein in the determination of the speed of the detection unit the reading and the calculated value are taken into consideration, wherein the time delay (?T) is specified as a function of the reading of the speed. In order to speed up the signal processing operation, only part of the image information, such as only every second, third, or fourth line, is used for determining the speed. |
