GeoVision LPR - Manual (Page 2)

The qualified image examples
To increase the license plate recognition accuracy, you need to install the LPR
camera in the proper way to capture the qualified plate images. When you
install the LPR camera, there are certain criteria to meet, including the plate
size, the lighting condition and the angle of the camera. In this document, we
provide the qualified image examples, and the unqualified image examples,
which are generated when the LPR camera is set in an improper way. We also
provide the easy installation instructions on how to fix those unqualified plate
images.
You should capture and fill the image with a full width of vehicle. In this way,
the height of the captured plate characters would approximately fall between
30 and 35 pixels.
