Functional Features

The system supports the enrolment of plates of interest, either manually or by importing CSV files. It allows the creation and management of unlimited groups of plates (e.g. white list, black list, stolen vehicles, employees, authorized vehicles).
The solution supports license plates from the following countries:

configured condition (e.g. car entering a parking at a certain time and not yet exited after 2
hours; or car passed between two checkpoints in less than 5 minutes)
• For each detected and read plate, automatic and real time estimation and storage of its relative
Country
• For each detected and read plate, automatic and real time estimation and storage of its relative
vehicle’s make, model and color(**)

o TechnoAware-CentralManager client, local or remote
o VTrack WebInterface
o API based on cgi call, for receiving automatically an xml file through http with the required
data
o compatible third-party platforms
o automatic periodical report in pdf format, customizable by project
• Enabling/disabling of configurations, functions and/or single rules by:
o an interrupt from an external input, through cgi call
o time scheduling, by timetabled configuration
o manual command, through VTrack-CentralManager client
o polling the status of an external I/O through network protocols, such as http, TCP, Modbus
• Built-in database for the storage of the processed events and data
• API for streaming out the real time processed video and/or metadata flow, for being acquired by
compatible third-party platforms
• Ability to manage redundant hardware architectures, by active FailOver function (both cases n:n
or n:1)
• Ability to work in virtualized environments

Configuration features

• Ability to configure unlimited virtual areas of interest, of any polygonal shape and size
• For each configured area of interest, ability to filter the plates detection according to their
movement direction (incoming, outcoming, both)
• Unlimited configurable no-processing areas, to inhibit not-of-interest parts of the image
• Ability to filter the plates detection and reading according to minimum and maximum size limits,
for the plate itself and/or for its characters
• Ability to configure a minimum reading confidence for each detected plate, for filtering all the
readings outcome below this confidence
• For each detected and tracked plate, ability to configure a reading timeframe within which to
extract multiple relative candidate strings, to be compared and weighted among each other’s for
increasing the confidence of the reading result
• Plate’s reading result defined according to:
o the most confident candidate outcome occurred within the configured reading timeframe
o the candidate outcome occurred more times within the configured reading timeframe
• Ability to associate a specific confidence weight for each specific supported Country according to
its expected occurrence
• Availability of OCR mode, for reading free text
• Ability to process the acquired video stream at a lower resolution and frame rate
• Ability to crop and process independently unlimited image portions of the acquired video flow
• Ability to configure different user profiles, allowing to enable or to inhibit the access to the
configuration of the modules

Additional built-in diagnostic functions

• Tampering module, for configuring and triggering an alarm on detection of camera obscured,
dazzled or moved for longer than a configured time
• QualityCam module, for configuring and triggering an alarm on camera’s reduction of visibility
(i.e. because of dirt, or defocusing) and/or misalignment
• VideoLoss function, to trigger an alarm notification in case of a loss of communication with a
video source
• Watchdog function, for the automatic restart of the module in case of critical error or eventual
restart of the hardware unit
• HeartBeat function, for the periodical notification of the correct working of the module to an
external device
• CheckConfig function, for checking by a html/xml request the status of the active configuration
• Writing and storing of log files for each main process of the module
• Monitor Client, for configuring automatic notifications in case of misfunctioning events of the
connected VTrack modules

Image and video streaming requirements

• Conditions of the plate in the processed image, for maximizing the detection and reading
performances:
o clearly visible and readable by the naked eye in the image, even in difficult environmental
conditions (night, heavy rain, snow, fog, sun glare, reflections, artificial lights,
under/overexposed camera, obstacles, …)
o entirely visible and readable in the image for at least 10-15 continuous frames
o each plate character being at least 20 pixels of height
o pan and tilt inclination angles of the plate, in respect with the camera view, being not over
±35°
• Minimum frame rate, according to the speed of the vehicles and the plates visibility and
readability requirements above indicated (i.e. 2-5 fps for still vehicles, up to 60 fps for fast
vehicles)
• Image resolution, in order to satisfy the requirement relative to the minimum size of the plate
characters, as above indicated
• Acquired and processed video stream being the less compressed possible (not compressed at all
would be preferable)

Processing requirements

• Computational need (*):
o CPU: considering, as reference, a single core with 2,80GHz base speed,
– up to 3 channels in parallel processing video flows in VGA resolution (640×480) at 10
frames per second
– up to 2 channels in parallel processing video flows in 4CIF resolution (704×576) at 10
frames per second
– up to 2 functions in parallel processing video flows in 800×600 resolution at 8 frames per
second
– up to 1 function processing video flows in FullHD (1080p) resolution (1920×1080) at 5
frames per second
o RAM: about 80MB for each function processed in parallel
o GPU: NVIDIA CUDA compatible, according to the always up-to-date page

complexity of the environment, the number and kind of targets, the specific function configured and the typology of hardware used. TechnoAware strongly suggests to always contact anyway its technical support team for doublechecking and validating for free the hardware meant to be used, for each project, before purchasing it.
