2.Mobile Auto-Detector

The Mobile Auto-Detectoris an automatic number plate reading system (ANPR) used on board patrol cars.A few systems functionalities that are not required by OSHP are disabled.

2.1 System Composition

System components are shown in Figure 1.

Figure 1a: the sensor case containing the cameras and system illuminators

Figure 1b: the case containing the processing unit and all electronic devices required for systemoperation

Figure 1c: the laptop computer that is used to display the systems human computer interface

2.2 System Functions

The system provides the following functions:

Continuous number plate reading by the two cameras mounted on the roof of the patrol car

Real time comparison with number plates in the hot list database

Alarm notification to the on board user

Storage of data and alarm images generated during the patrolling

Real time display of video stream from cameras

Insertion, removal and searching of plates in the hot list database during the patrolling

Data download to operations center at end of patrolling (detected plate alarms and images)

Update of car hot list database from operations center at start of patrolling

2.3 Operating Procedure

To operate the system proceed as follows:

The system is powered up automatically when the car ignition is switched on and is ready to operatein about a minute

At the start of patrolling (or periodically), patrol cars must stop in the vicinity of the data transfer areato load/update the hot list database

Rev.: 1.1 Data: 9-lug-04 Pag. 7/19


On board users are required to handle alarm events during patrolling

At the end of the patrolling (or periodically), patrol cars must stop in the vicinity of the data transferarea to upload alarm detection data gathered during the patrolling

The system is automatically powered down a couple of minutes after the patrol car ignition isswitched off. If system data upload/download is in progress, the system automatically powers itselfdown on completion.

As can be seen, the system does not significantly increase on board user workload during service. The onlysystem interaction required is during alarm management, as the on board user must handle the eventsignaled by the system.

2.4 Orientation and Visual Field of the Cameras

Figure 2 illustrates the orientation and the visual field of the systems cameras. The number plate of a car isread when it completely enters the cameras field of vision.

Figure 18 : Search failed dialog box

4.5Alarm Management

4.5.1Alarm DetectionA search is performed in the hot list database for each plate read by the system. If the plate is found in thedatabase, an alarm is generated. The system can read plates, but not the associated state. If the hot listdatabase contains the same plate (e.g. the same sequence of letters and numbers) but from different states(e.g.: [AA000AA, OH], [AA000AA, CA], [AA000AA, FL]), the system generates an alarm and presents thevarious plate/state alternatives. During alarm management, the on board user must verify all the alternativespresented by the system and accept the correct one or reject the plate if none match. The verification andvalidation procedures are described in the paragraphs below.

During alarm display, the system continues to read plates and search for them in the hot list database asusual. New alarms are presented to the on board user only after the previous alarm has been handled.

Rev.: 1.1 Data: 9-lug-04 Pag. 16/19


4.5.2 System ActionsIf a plate read by the system is found in the hot list database an alarm is generated automatically. Figure 19illustrates the human computer interface when an alarm is generated.

Figure 19 : Interface in alarm state

The following actions are performed by the system:

The dialog box in Figure 19a is displayed to indicate that a new alarm has been detected

An acoustic alarm is generated to signal the new alarm to the on board user

The arrow indicator in Figure 19b is activated to indicate the camera that has generated the alarm

The display area contains the image of the plate and associated alarm data

The Timer in Figure 19c indicates how much time is left for the on board user to validate the alarm

The Accept and Reject buttons in Figure 19d are enabled to allow the on board user to validate thealarm

The alarm indicators in Figure 19e are displayed to inform the on board user that alarm handling is inprogress

The zoom button in Figure 19f is enabled to allow the on board user to zoom in on the plate detected

The scroll buttons in Figure 19g are activated only if more than one plate/state alternative is presentin the database, enabling the on board user to scroll through the various possibilities

The counter in Figure 19h indicates the number of transits the system have read since it waspowered up

4.5.3 On Board User ActionsOn board user alarm management requires the following actions:

Click on the OK button in Figure 19a

Check whether the alarm generated by the system is correct

Accept or reject the alarm


17/19



Rev.: 1.1 Data: 9-lug-04 Pag. 17/19


Alarms generated must be verified by comparing the plate data read by the system, indicated in the Transitarea in the window in Figure 19, with the plate image displayed in the Show Image area in Figure 19. If morethan one plate/state alternative is present, the on board user must use the buttons in Figure 19g to scrollthrough the list of possibilities. These buttons are displayed in red when the list can be scrolled in thedirection indicated by the arrow and in gray when scrolling that direction is no longer possible.

Alarms are accepted or rejected depending on the outcome of the verification performed by the on boarduser. If the data read and identified by the system matches the plate displayed in the Show Image area, thealarm must be accepted. If not it must be rejected. If more than one plate/state alternative is presented, theon board user must verify all of them. If one of the alternatives is accepted, the data indicated in the Transit

area of the window in Figure 19 must match the plate in the image displayed.

On board users accept or reject alarms using the buttons illustrated in Figure 19d.

If the on board user does not complete the alarm validation procedure within the time limit set for the Timer,the alarm is automatically accepted. The system displays the dialog box in Figure 20 to inform the on boarduser that the Timerperiod has expired.

Figure 20 : Timer alarm expiry dialog box

4.6 Data Transfer

Data transfer is performed automatically when the car is in the data transfer area.

During this phase the operations center system establishes a connection with the Mobile Auto-Detectorsystem to download the alarms generated during the patrolling and update the hot list database.

The on board user is informed of the fact that data transfer is in progress by the Data Transferringindicatorin the System State area in Figure 21, which goes green.

4.7 Diagnostic Messages

The system can generate a Diagnostic Message to inform the on board user of a particular operatingcondition.

4.7.1 Software Update ProcessSoftware update session can be scheduled by the system administrator when a new system softwarerelease is available. In this case, during the data transfer operation, the software update process is

automatically performed by the system. The dialog box in Figure 22 notifies the on board user that theprocess is in progress.

Figure 22 : Software update process in progress dialog box

If the software update process is completed correctly, the dialog box in Figure 23 notifies the on board user.
