GeoVision What is the best license plate size to optimize LPR result?

Back to GeoVision Support | Support Home

In order to optimize recognition result in GV-LPR, we recommend each letter and number on the license plate to be around 32 pixels in height

      To find the height of the license plate characters:

  1. Save a snapshot of the recognition result in JPEG format.
  2. Open the snapshot using Microsoft Paint.
  3. Using the "Select" tool in Paint, create a box around the license plate characters.
  4. The dimension of the box should be shown at the lower-right hand corner in Paint. The later number indicates the height of the characters (in pixels).
