2.2 Installing Hardware

Types and quality of video capture boards depend on used video cameras (see SecurOS InstallationGuide).

2.2.1 Installing video cameras

Note: Connecting video cameras are fully described in SecurOS Installation Guide.

The video cameras have to be installed directly next to the path of the passing vehicles. The bestcamera position (for the qualitative detection rates) the camera is on the road and looking down atan angle of 10-20 degrees. The width of the control zone is defined by its horizontal resolution(see below). For the traditional TV cameras the maximum width of the control zone is up to fivemeters. For megapixel cameras it can be more, but in this case increases considerably the load on thecomputer.

LPR Module 14

Deploying Module

User Guide

There are some guidelines for choosing and setting up video cameras. For list of recommendedcameras see Appendix A: Recommended cameras on page 73.

Warning! Wrong installation may cause license plate recognition errors.

• Camera type. It is recommended to use a monochrome camera with high resolution and 1/2” or1/3” interleave transfer sensor and with manual exposure set to 1/2000 or 1/5000 sec.

This is necessary to get better images of high speed cars license plate numbers.

Example: At a speed of 60 km/h a car passes 15 meters per a second, and 1 mm— for 1/2000 second.If a vehicle speed is less then 15 km/h, e.g. on parking, then the 1/500 second explosure is enough.

• On choosing objective type and setting focal length use the following items:

For the majority of the European countries the licence plate symbol thickness is 1 cm, and it’swidth is—50 cm. For better recognition the symbol stroke on image must be at least 2 pixels.On horizontal frame with the size of from 700 till 750 pixels the under-control zone will beabout (for cameras that works in NTSC format with frame width in 640 pixels the zone will beless. In a pinch when 1 cm takes 1,5 pixels and frame width is 700 pixels then the zone sizewill be the following: 700/1.5 = 4.7 meters (that is about one and a half lane). Reducing theresolution lower than 1.5 pixels by 1 cm can affect the quality of recognition, especially at lowcontrast and dirty plates.

Figure 4: Camera zoom setup

• Camera features. Automatic focus and levelling quaking image features has to be disabled.

• Camera with auto-aperture (ELC). Auto-aperture may be used when there are no quick bright-ness changes within the camera view. In other cases, this feature has to be turned off.

To setup the iris diaphragm:

1. Turn the objective to auto-aperture work.

2. Almost shade the camera aperture.

3. Make some snap-shots of cars.

4. Watch the created images from the video-archive. If these images are blurry, slightly openthe aperture and repeat the procedure.

• Camera angle of rotation. Mount a camera in such a way that the horizontal level of thecamera does not deviate from the horizon more than 10◦.

User Guide

Figure 5: The right camera installation (the angle less than 10◦)

Figure 6: The wrong camera installation (the angle more than 10◦)

• Camera angle of inclination. The best camera position is that the cars move directly towarda camera. Some deviations are acceptable: horizontal—not more than 30◦ and vertical—notmore than 40◦.

Warning! Acceptable deviation of horizontal camera angle may not be more than 20◦, whenlicense plates of the following countries are recognized by Module: USA, Canada, Paraguay,Argentina, etc. This value is due to smaller width of symbols used for license plates in thesecountries.

2.2.2 Thermo-box

Use thermo-boxes reasoning from climatic conditions of the region. Its size is determined by cameraand objective ones. It is recommended to use thermo-boxes with heating and blower functions.

2.2.3 Lightning guard

Use lightning guard equipment to protect connected active devices from external natural interferencedue to strokes of lightning.

2.2.4 Illumination

It is enough natural lighting on solar day (but not less than 50 lux). However on night-time usediffused illumination with intensity 300 lux.

Warning! There has to be no glare on receiving video and no exposure on obtained image.

On night-time one can use additional light sources, e. g. searchlights with either 500–1000 wattincandescent lamp or 250–400 watt elements of diode-resistor logic. Also use setting IR searchlightin case there are no place for additional illumination. Model of IR searchlight is selected dependingon necessary illumination angle and distance. With IR searchlight it is recommended to use camerastogether with IR Corrective filter for glare and camera extra exposure compensation.

Note: IR illuminators by Pelco are recommended.

Each recognizedlicense plate is stored in a database with an additional information (date, time, recognition cameraID) and displayed on the Module interface along with all information received from the license plate(video of the passing car, matching with external or/and local database and details on correspondingaccess level).

Note: There are two different Module objects for recognition of licence plates from video streams withlow fps (below six) and with normal fps (six and larger), see 3.2.5 License plate recognizer 6 fps onpage 36.

License plates found in “alarmed” and/or informational external databases (“alarmed” license plates)are marked with the corresponding color and displayed on the Module interface.

Module can be configured to inform operator about maximum speed violation facts using velocitymeasurement obtained from video analysis.

Operator has a visual control tools as well as the ability to search through the database. For eachlicense plate number in the database it is possible to view the video and video frame archived on thesystem’s hard drive.

Below is the recommended scheme of operator interface.

Analyse video fromcamera

Select a camera that will be monitoring the vehicle license plates.Attention! For the corresponding Camera object set the following para-meters:

• Pre-recording phase duration—set an approximate vehicle tran-sit time by camera view (in seconds).

Warning! The best Pre-recording phase duration parametervalue should somewhat exceed the average time spent in the frame.However, if it is a very large (more then 10 seconds), then onecan restrict, for example, ten seconds, because the more time isset the greater the total load on the system (for memory andperformance).

• Resolution—set the value according with the planned under-controlled zone width (actually for megapixel cameras), cornersof the cameras installation and the requirement that on 1 sm ofthe zone cross-selection (visible in a frame) it is necessary atleast 1.2–1.5, (better 2), pixels (see 2.2.1 Installing video cam-eras on page 13). If the signal comes with the interlaced scan-ning (typically for analog cameras) it is necessary to select theHigh (CIF2) value or, at least the Normal (CIF1) value. For thecamera with the progressive scanning (usually it is IP-cameras)select the Complete (CIF4) value.

Recognitionalgorithm sensitivity

Move the slider to specify the sensitivity level of the recognition al-gorithm. The slider has only two positions, corresponding to Stan-dard and High sensitivities. The latter ensures higher recognition rateon low-contrast license plates at the cost of using more computation-ally demanded recognition algorithm resulting in a 30% increase of theprocessor load on average, if compared to Standard level. High levelis recommended to decrease the number of poorly (or completely not)recognised license plates. If the user priority is to avoid capturing ve-hicles with false or poor recognition results, then Standard level isrecommended.

Analyze eachhalf-frame

Select this check box to enable recognition on both the odd and evenhalf-fields of interlaced video frames. At the cost of nearly doubling theprocessor load, this will make possible analyzing the incoming videoat the effective rate of 50 or 60 fps (for NTSC cameras), which is asensible choice to be able to recognize number plates on cars travellingat great speed. This check box is grayed unless the camera is set tocapture the full frame. Activating this option is worth considering ifyou know for sure that the full frame is interlaced, which is typicalof conventional TV cameras (there are exceptions, though) and quiteuncommon (although possible) with IP cameras.

Camera orientation

Camera orientation

Select this check box to specify corners of the stationary camera ori-entation (it makes sense to specify them with a view of more effectivefiltering numbers which can arise on extraneous inscriptions and regularstructures, such as lattices of heat sinks of cars). Corners need to be setto within 3-5 degrees. In any case the inclination should not be morethan 400◦, and turn is no more 30–35◦, and for the countries with highand narrow number sign characters (as in the USA and many countriesof Latin America) the limiting angle of rotation of the camera will beless. To set camera orientation follows with care when the corner be-tween a direction of the camera and a direction of movement of the carstrongly varies, for example, when cars make sharp manoeuvre in thecourse of movement, turn.Warning: to set camera orientation does not follow for the countries onwhich numbers the proportional font (for example, Malaysia and partlyPortugal is used) as it can lead to skip “short” numbers including someof narrow characters.

Select this check box to create a log file of the Module events.

Note: Statistics is reasonable for using only in case of stationarily fixed camera. In case of change of itsposition or a visual direction earlier gathered statistics is unsuitable.Statistics should not be used at such position of the camera when in the same part of a frame there canbe numbers of essentially different size. For example, when the camera is strengthened low over roadand looks directly forwards so �the horizon line� is visible. In this case number of the moving car willremain practically on a place and only to vary in the sizes.The best case—when the camera is fixed over a road and its view covers rather small site of road.

Frequently Asked Questions

User Guide

5. Frequently Asked Questions

Question: How can I put previously recorded video in SecurOS interface?

To put previously recorded video in SecurOS interface:

1. Copy file of previously recorded video to the SecurOS folder (e. g. C:\SecurOS). Rename thisfile as X. Y, where X—integer number from 0 till 31, Y—integer number from 1 till 16.

2. Create Video Capture Device object (see SecurOS Administration Guide) in SecurOS object treeand set the following parameters:

• Type → select the Virtual value from the drop-down list box

• PCI Channel → select the X value (see item 1). For example, if the file name was 0. 01,then one need to set the 0 value.

Warning! Channel number should not coincide with channels used in other Video CaptureDevice objects on the same computer, otherwise the video will not be displayed on the videomonitor. In this case rename the file by changing its X value to make it differ from any numberof already used channels.

3. Create Camera object as a child one for the just created Video Capture Device object (seeitem 2). Define a channel number: set the Y value (see item 1). For example, if the file namewas 0. 01, then one need to set the 1 value.

Question: What value must be set for the “Pre-recording phase duration” Camera object para-

meter?

In Pre-recording phase duration one need to set an average time of car passing in camera view. Itis recommended to set a value not more than 10 seconds. Setting more than 10 seconds may causesystem errors.

Question: How can I create an external database query using several data fields?

The result of an external database connection parameters query execution (see 3.2.6.1 The RecognizersTab on page 37) should be a data string. The following example is a query to several external databasefields:

SELECT CAST (’Car model ’ AS TEXT) || model || CAST(’ was stolen ’ AS TEXT)

|| stealing date || CAST(’ and in search from ’ AS TEXT)

|| post date FROM steal WHERE LPR=UPPER(?).

The query result would be a list of messages like Car model ... was stolen ...
