Method and apparatus for capturing an image of a speed-violating vehicle
First Claim
1. A method for recording images of vehicles that pass through a section between an entrance and an exit at excessive speed, comprising the following steps:
- capturing, by a first station processor at the entrance, an entry image and the entry time of a vehicle at the entrance, generating a unique object identifier for the vehicle and storing the entry image and the entry time under the object identifier, wherein the generated object identifier is independent from the identity of the vehicle and is at least one of a randomly-selected value or taken from a list of predetermined identifiers;
tracking the movement of the vehicle, which is being continuously referenced during the tracking by way of the object identifier, over the entire section using a sensor arrangement wherein the sensor arrangement transfers the object identifier to an exit station when the sensor arrangement establishes that the vehicle reaches the exit;
capturing, by a second station processor at the exit, the exit time of the vehicle that is referenced by way of the object identifier at the exit; and
if a comparison of the captured exit time to the stored entry time indicates a speed that exceeds a threshold value;
determining the entry image stored under the object identifier;
otherwise;
sending, by the second station processor, a command to the first station processor that causes the first station processor to delete the entry image stored under the object identifier.

Abstract
Methods and devices are provided for recording images of vehicles that pass through a section between an entrance and an exit at excessive speed, comprising the following steps: capturing an entry time of a vehicle at the entrance, generating a unique object identifier for the vehicle and storing the entry time under the object identifier; tracking the movement of the vehicle, which is being continuously referenced by way of the object identifier, over the entire section using a sensor arrangement; capturing an exit time of the vehicle that is referenced by way of the object identifier at the exit; and if a comparison of the captured exit time to the stored entry time indicates a speed that exceeds a threshold value: determining an entry image stored under the object identifier or creating an exit image of the vehicle.

10. A device for recording images of vehicles that pass through a section between an entrance and an exit at excessive speed, comprising:
-
a first camera disposed at the entrance for capturing an entry image; a processor disposed at the entrance for generating a unique object identifier for the vehicle and storing the entry image and an entry time captured for the vehicle under the object identifier in a memory, wherein the generated object identifier is independent from the identity of the vehicle and is at least one of a randomly-selected value or taken from a list of predetermined identifiers; a sensor arrangement, which receives the object identifier from the processor and tracks the vehicle that is referenced by way of the object identifier over the entire section, wherein the sensor arrangement transfers the object identifier to an exit station when the sensor arrangement establishes that the vehicle reaches the exit; and an evaluation unit disposed at the exit, which is configured to determine the entry time stored under the object identifier and, if a comparison of a captured exit time of the vehicle that is referenced by way of the object identifier to the determined entry time indicates a speed that exceeds a threshold value, determine the entry image stored under the object identifier, or otherwise send a command to the processor disposed at the entrance that causes the processor to delete the entry image stored under the object identifier. - View Dependent Claims (11, 12, 13, 14)
