used to capture two or one lane simultaneously. In the case of two lanes, the Panoramic

Multiple Exposures
The ITSCAM FF 600
Multiple Exposures
functionality generates two to four sequential images per request,
by configuring the Number of captures per pulse via interface. This feature can increase the accuracy rate
in the automatic identification of plates and identify vehicles that had some kind of concealment when the
first image is captured. The settings that may vary are:
•
The Flash intensity, always corresponding to a percentage of the initial trigger. This option is
available for the line of ITSLUX illuminators from Pumatronix, designed to deliver the best results
with
Multiple Exposures
;
•
The image sensor exposure time (
shutter
), generating images varying the amount of light captured;
•
Digital post-processing (
Gain
), which allows the images to lighten or darken.
When using
Multiple Exposures
(or photos), the first capture allows the non-reflective plates to be clearly
visualized and the second capture will be made with a weak flash, which allows the reflective plates not to
be saturated and show a better visualization:

OCR
ITSCAM FF 600 can recognize license plates from Brazil (in the Brazilian and Mercosur standards),
Argentina, Chile, Mexico, Paraguay, Uruguay, and the entire Southern Cone simultaneously. When enabled,
recognition is done on all captured images.
OCR also allows you to define an ROI (Region of Interest of the Image), to reduce the processing of image
regions where there is no plate to find. Access the ITSCAM 600 device manual for all available OCR settings.

is a feature applied to automatic license plate character reading (OCR) step results. This
analytic defines which string best describes the vehicle plate captured in the image. The algorithm compares
